# Sample apps with Compose
|
||||
|
||||
The following samples show the various aspects of how to work with Docker
|
||||
Compose. As a prerequisite, be sure to [install Docker Compose](https://docs.docker.com/compose/install/)
|
||||
if you have not already done so.
|
||||
|
||||
## Key concepts these samples cover
|
||||
|
||||
The samples should help you to:
|
||||
|
||||
- define services based on Docker images using
|
||||
[Compose files](https://docs.docker.com/compose/compose-file/) `docker-compose.yml` files
|
||||
- understand the relationship between `docker-compose.yml` and
|
||||
[Dockerfiles](https://docs.docker.com/engine/reference/builder/)
|
||||
- learn how to make calls to your application services from Compose files
|
||||
|
||||
## Samples tailored to demo Compose
|
||||
|
||||
These samples focus specifically on Docker Compose:
|
||||
|
||||
- [Quickstart: Compose and Django](./django/README.md) - Shows how to use Docker Compose to set up and run a simple Django/PostgreSQL app.
|
||||
|
||||
- [Quickstart: Compose and Rails](./rails/README.md) - Shows how to use
|
||||
Docker Compose to set up and run a Rails/PostgreSQL app.
|
||||
|
||||
- [Quickstart: Compose and WordPress](./wordpress/README.md) - Shows how to
|
||||
use Docker Compose to set up and run WordPress in an isolated environment
|
||||
with Docker containers.

# Quickstart: Compose and Django
|
||||
|
||||
This quick-start guide demonstrates how to use Docker Compose to set up and run a simple Django/PostgreSQL app. Before starting,
|
||||
[install Compose](https://docs.docker.com/compose/install/).
|
||||
|
||||
## Define the project components
|
||||
|
||||
For this project, you need to create a Dockerfile, a Python dependencies file,
|
||||
and a `docker-compose.yml` file. (You can use either a `.yml` or `.yaml` extension for this file.)
|
||||
|
||||
1. Create an empty project directory.
|
||||
|
||||
You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain resources to build that image.
|
||||
|
||||
2. Create a new file called `Dockerfile` in your project directory.
|
||||
|
||||
The Dockerfile defines an application's image content via one or more build
|
||||
commands that configure that image. Once built, you can run the image in a
|
||||
container. For more information on `Dockerfile`, see the [Docker user guide](https://docs.docker.com/get-started/)
|
||||
and the [Dockerfile reference](https://docs.docker.com/engine/reference/builder/).
|
||||
|
||||
3. Add the following content to the `Dockerfile`.
|
||||
|
||||
```dockerfile
|
||||
# syntax=docker/dockerfile:1
|
||||
FROM python:3
|
||||
ENV PYTHONDONTWRITEBYTECODE=1
|
||||
ENV PYTHONUNBUFFERED=1
|
||||
WORKDIR /code
|
||||
COPY requirements.txt /code/
|
||||
RUN pip install -r requirements.txt
|
||||
COPY . /code/
|
||||
```
|
||||
|
||||
This `Dockerfile` starts with a [Python 3 parent image](https://hub.docker.com/r/library/python/tags/3/).
|
||||
The parent image is modified by adding a new `code` directory. The parent image is further modified
|
||||
by installing the Python requirements defined in the `requirements.txt` file.
|
||||
|
||||
4. Save and close the `Dockerfile`.
|
||||
|
||||
5. Create a `requirements.txt` in your project directory.
|
||||
|
||||
This file is used by the `RUN pip install -r requirements.txt` command in your `Dockerfile`.
|
||||
|
||||
6. Add the required software in the file.
|
||||
|
||||
```python
|
||||
Django>=3.0,<4.0
|
||||
psycopg2>=2.8
|
||||
```
|
||||
|
||||
7. Save and close the `requirements.txt` file.
|
||||
|
||||
8. Create a file called `docker-compose.yml` in your project directory.
|
||||
|
||||
The `docker-compose.yml` file describes the services that make your app. In
|
||||
this example those services are a web server and database. The compose file
|
||||
also describes which Docker images these services use, how they link
|
||||
together, any volumes they might need to be mounted inside the containers.
|
||||
Finally, the `docker-compose.yml` file describes which ports these services
|
||||
expose. See the [`docker-compose.yml` reference](https://docs.docker.com/compose/compose-file/) for more
|
||||
information on how this file works.
|
||||
|
||||
9. Add the following configuration to the file.
|
||||
|
||||
```yaml
|
||||
services:
|
||||
db:
|
||||
image: postgres
|
||||
volumes:
|
||||
- ./data/db:/var/lib/postgresql/data
|
||||
environment:
|
||||
- POSTGRES_DB=postgres
|
||||
- POSTGRES_USER=postgres
|
||||
- POSTGRES_PASSWORD=postgres
|
||||
web:
|
||||
build: .
|
||||
command: python manage.py runserver 0.0.0.0:8000
|
||||
volumes:
|
||||
- .:/code
|
||||
ports:
|
||||
- "8000:8000"
|
||||
environment:
|
||||
- POSTGRES_NAME=postgres
|
||||
- POSTGRES_USER=postgres
|
||||
- POSTGRES_PASSWORD=postgres
|
||||
depends_on:
|
||||
- db
|
||||
```
|
||||
|
||||
This file defines two services: The `db` service and the `web` service.
|
||||
|
||||
> Note:
|
||||
>
|
||||
> This uses the build in development server to run your application
|
||||
> on port 8000. Do not use this in a production environment. For more
|
||||
> information, see [Django documentation](https://docs.djangoproject.com/en/3.1/intro/tutorial01/#the-development-server){: target="_blank" rel="noopener" class="_”}.
|
||||
|
||||
10. Save and close the `docker-compose.yml` file.
|
||||
|
||||
## Create a Django project
|
||||
|
||||
In this step, you create a Django starter project by building the image from the build context defined in the previous procedure.
|
||||
|
||||
1. Change to the root of your project directory.
|
||||
|
||||
2. Create the Django project by running the [docker compose run](https://docs.docker.com/engine/reference/commandline/compose_run/)
|
||||
command as follows.
|
||||
|
||||
```console
|
||||
sudo docker compose run web django-admin startproject composeexample .
|
||||
```
|
||||
|
||||
This instructs Compose to run `django-admin startproject composeexample`
|
||||
in a container, using the `web` service's image and configuration. Because
|
||||
the `web` image doesn't exist yet, Compose builds it from the current
|
||||
directory, as specified by the `build: .` line in `docker-compose.yml`.
|
||||
|
||||
Once the `web` service image is built, Compose runs it and executes the
|
||||
`django-admin startproject` command in the container. This command
|
||||
instructs Django to create a set of files and directories representing a
|
||||
Django project.
|
||||
|
||||
3. After the `docker compose` command completes, list the contents of your project.
|
||||
|
||||
```console
|
||||
$ ls -l
|
||||
|
||||
drwxr-xr-x 2 root root composeexample
|
||||
drwxr-xr-x 3 root root data
|
||||
-rw-rw-r-- 1 user user docker-compose.yml
|
||||
-rw-rw-r-- 1 user user Dockerfile
|
||||
-rwxr-xr-x 1 root root manage.py
|
||||
-rw-rw-r-- 1 user user requirements.txt
|
||||
```
|
||||
|
||||
If you are running Docker on Linux, the files `django-admin` created are
|
||||
owned by root. This happens because the container runs as the root user.
|
||||
Change the ownership of the new files.
|
||||
|
||||
Do not change the permission of the data folder where Postgres has its file, otherwise Postgres will not be able to start due to permission issues.
|
||||
|
||||
```console
|
||||
sudo chown -R $USER:$USER composeexample manage.py
|
||||
```
|
||||
|
||||
If you are running Docker on Mac or Windows, you should already
|
||||
have ownership of all files, including those generated by
|
||||
`django-admin`. List the files just to verify this.
|
||||
|
||||
```console
|
||||
$ ls -l
|
||||
|
||||
total 32
|
||||
-rw-r--r-- 1 user staff 145 Feb 13 23:00 Dockerfile
|
||||
drwxr-xr-x 6 user staff 204 Feb 13 23:07 composeexample
|
||||
-rw-r--r-- 1 user staff 159 Feb 13 23:02 docker-compose.yml
|
||||
-rwxr-xr-x 1 user staff 257 Feb 13 23:07 manage.py
|
||||
-rw-r--r-- 1 user staff 16 Feb 13 23:01 requirements.txt
|
||||
```
|
||||
|
||||
### Connect the database
|
||||
|
||||
In this section, you set up the database connection for Django.
|
||||
|
||||
1. In your project directory, edit the `composeexample/settings.py` file.
|
||||
|
||||
2. Replace the `DATABASES = ...` with the following:
|
||||
|
||||
```python
|
||||
# settings.py
|
||||
|
||||
import os
|
||||
|
||||
[...]
|
||||
|
||||
DATABASES = {
|
||||
'default': {
|
||||
'ENGINE': 'django.db.backends.postgresql',
|
||||
'NAME': os.environ.get('POSTGRES_NAME'),
|
||||
'USER': os.environ.get('POSTGRES_USER'),
|
||||
'PASSWORD': os.environ.get('POSTGRES_PASSWORD'),
|
||||
'HOST': 'db',
|
||||
'PORT': 5432,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
These settings are determined by the
|
||||
[postgres](https://hub.docker.com/_/postgres) Docker image
|
||||
specified in `docker-compose.yml`.
|
||||
|
||||
3. Save and close the file.
|
||||
|
||||
4. Run the [docker compose up](https://docs.docker.com/engine/reference/commandline/compose_up/) command from the top level directory for your project.
|
||||
|
||||
```console
|
||||
$ docker compose up
|
||||
|
||||
djangosample_db_1 is up-to-date
|
||||
Creating djangosample_web_1 ...
|
||||
Creating djangosample_web_1 ... done
|
||||
Attaching to djangosample_db_1, djangosample_web_1
|
||||
db_1 | The files belonging to this database system will be owned by user "postgres".
|
||||
db_1 | This user must also own the server process.
|
||||
db_1 |
|
||||
db_1 | The database cluster will be initialized with locale "en_US.utf8".
|
||||
db_1 | The default database encoding has accordingly been set to "UTF8".
|
||||
db_1 | The default text search configuration will be set to "english".
|
||||
|
||||
<...>
|
||||
|
||||
web_1 | July 30, 2020 - 18:35:38
|
||||
web_1 | Django version 3.0.8, using settings 'composeexample.settings'
|
||||
web_1 | Starting development server at http://0.0.0.0:8000/
|
||||
web_1 | Quit the server with CONTROL-C.
|
||||
```
|
||||
|
||||
At this point, your Django app should be running at port `8000` on
|
||||
your Docker host. On Docker Desktop for Mac and Docker Desktop for Windows, go
|
||||
to `http://localhost:8000` on a web browser to see the Django
|
||||
welcome page.
|
||||
|
||||
|
||||
|
||||
> Note:
|
||||
>
|
||||
> On certain platforms (Windows 10), you might need to edit `ALLOWED_HOSTS`
|
||||
> inside `settings.py` and add your Docker host name or IP address to the list.
|
||||
> For demo purposes, you can set the value to:
|
||||
>
|
||||
> ```python
|
||||
> ALLOWED_HOSTS = ['*']
|
||||
> ```
|
||||
>
|
||||
> This value is **not** safe for production usage. Refer to the
|
||||
> [Django documentation](https://docs.djangoproject.com/en/1.11/ref/settings/#allowed-hosts) for more information.
|
||||
|
||||
5. List running containers.
|
||||
|
||||
In another terminal window, list the running Docker processes with the `docker ps` or `docker container ls` command.
|
||||
|
||||
```console
|
||||
$ docker ps
|
||||
|
||||
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
||||
def85eff5f51 django_web "python3 manage.py..." 10 minutes ago Up 9 minutes 0.0.0.0:8000->8000/tcp django_web_1
|
||||
678ce61c79cc postgres "docker-entrypoint..." 20 minutes ago Up 9 minutes 5432/tcp django_db_1
|
||||
```
|
||||
|
||||
6. Shut down services and clean up by using either of these methods:
|
||||
|
||||
* Stop the application by typing `Ctrl-C` in the same shell in where you
|
||||
started it:
|
||||
|
||||
```console
|
||||
Gracefully stopping... (press Ctrl+C again to force)
|
||||
Killing test_web_1 ... done
|
||||
Killing test_db_1 ... done
|
||||
```
|
||||
|
||||
* Or, for a more elegant shutdown, switch to a different shell, and run
|
||||
[docker compose down](https://docs.docker.com/engine/reference/commandline/compose_down/) from the top level of your
|
||||
Django sample project directory.
|
||||
|
||||
```console
|
||||
$ docker compose down
|
||||
|
||||
Stopping django_web_1 ... done
|
||||
Stopping django_db_1 ... done
|
||||
Removing django_web_1 ... done
|
||||
Removing django_web_run_1 ... done
|
||||
Removing django_db_1 ... done
|
||||
Removing network django_default
|
||||
```
|
||||
|
||||
Once you've shut down the app, you can safely remove the Django project directory (for example, `rm -rf django`).

This Quickstart guide shows you how to use Docker Compose to set up and run
|
||||
a Rails/PostgreSQL app. Before starting, [install Compose](https://docs.docker.com/compose/install/).
|
||||
|
||||
## Define the project
|
||||
|
||||
Start by setting up the files needed to build the app. The app will run inside a
|
||||
Docker container containing its dependencies. Defining dependencies is done using
|
||||
a file called `Dockerfile`. To begin with, the Dockerfile consists of:
|
||||
|
||||
```dockerfile
|
||||
# syntax=docker/dockerfile:1
|
||||
FROM ruby:2.5
|
||||
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client
|
||||
WORKDIR /myapp
|
||||
COPY Gemfile /myapp/Gemfile
|
||||
COPY Gemfile.lock /myapp/Gemfile.lock
|
||||
RUN bundle install
|
||||
|
||||
# Add a script to be executed every time the container starts.
|
||||
COPY entrypoint.sh /usr/bin/
|
||||
RUN chmod +x /usr/bin/entrypoint.sh
|
||||
ENTRYPOINT ["entrypoint.sh"]
|
||||
EXPOSE 3000
|
||||
|
||||
# Configure the main process to run when running the image
|
||||
CMD ["rails", "server", "-b", "0.0.0.0"]
|
||||
```
|
||||
|
||||
That'll put your application code inside an image that builds a container
|
||||
with Ruby, Bundler and all your dependencies inside it. For more information on
|
||||
how to write Dockerfiles, see the [Docker user guide](https://docs.docker.com/get-started/)
|
||||
and the [Dockerfile reference](https://docs.docker.com/engine/reference/builder/).
|
||||
|
||||
Next, open an editor and create a bootstrap `Gemfile` which just loads Rails. This will be overwritten in a moment by `rails new`.
|
||||
|
||||
```ruby
|
||||
source 'https://rubygems.org'
|
||||
gem 'rails', '~>5'
|
||||
```
|
||||
|
||||
Create an empty `Gemfile.lock` file to build our `Dockerfile`.
|
||||
|
||||
```console
|
||||
$ touch Gemfile.lock
|
||||
```
|
||||
|
||||
Next, provide an entrypoint script to fix a Rails-specific issue that
|
||||
prevents the server from restarting when a certain `server.pid` file pre-exists.
|
||||
This script will be executed every time the container gets started.
|
||||
`entrypoint.sh` consists of:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
# Remove a potentially pre-existing server.pid for Rails.
|
||||
rm -f /myapp/tmp/pids/server.pid
|
||||
|
||||
# Then exec the container's main process (what's set as CMD in the Dockerfile).
|
||||
exec "$@"
|
||||
```
|
||||
|
||||
Finally, `docker-compose.yml` is where the magic happens. This file describes
|
||||
the services that comprise your app (a database and a web app), how to get each
|
||||
one's Docker image (the database just runs on a pre-made PostgreSQL image, and
|
||||
the web app is built from the current directory), and the configuration needed
|
||||
to link them together and expose the web app's port.
|
||||
|
||||
```yaml
|
||||
services:
|
||||
db:
|
||||
image: postgres
|
||||
volumes:
|
||||
- ./tmp/db:/var/lib/postgresql/data
|
||||
environment:
|
||||
POSTGRES_PASSWORD: password
|
||||
web:
|
||||
build: .
|
||||
command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
|
||||
volumes:
|
||||
- .:/myapp
|
||||
ports:
|
||||
- "3000:3000"
|
||||
depends_on:
|
||||
- db
|
||||
```
|
||||
|
||||
> **Tip**
|
||||
>
|
||||
> You can use either a `.yml` or `.yaml` extension for this file.
|
||||
|
||||
### Build the project
|
||||
|
||||
With those files in place, you can now generate the Rails skeleton app
|
||||
using [docker compose run](https://docs.docker.com/engine/reference/commandline/compose_run/):
|
||||
|
||||
```console
|
||||
$ docker compose run --no-deps web rails new . --force --database=postgresql
|
||||
```
|
||||
|
||||
First, Compose builds the image for the `web` service using the `Dockerfile`.
|
||||
The `--no-deps` tells Compose not to start linked services. Then it runs
|
||||
`rails new` inside a new container, using that image. Once it's done, you
|
||||
should have generated a fresh app.
|
||||
|
||||
List the files.
|
||||
|
||||
```console
|
||||
$ ls -l
|
||||
|
||||
total 64
|
||||
-rw-r--r-- 1 vmb staff 222 Jun 7 12:05 Dockerfile

||||

|
||||
drwxr-xr-x 3 vmb staff 102 Jun 7 12:09 vendor
|
||||
```
|
||||
|
||||
If you are running Docker on Linux, the files `rails new` created are owned by
|
||||
root. This happens because the container runs as the root user. If this is the
|
||||
case, change the ownership of the new files.
|
||||
|
||||
```console
|
||||
$ sudo chown -R $USER:$USER .
|
||||
```
|
||||
|
||||
If you are running Docker on Mac or Windows, you should already have ownership
|
||||
of all files, including those generated by `rails new`.
|
||||
|
||||
Now that you’ve got a new Gemfile, you need to build the image again. (This, and
|
||||
changes to the `Gemfile` or the Dockerfile, should be the only times you’ll need
|
||||
to rebuild.)
|
||||
|
||||
```console
|
||||
$ docker compose build
|
||||
```
|
||||
|
||||
### Connect the database
|
||||
|
||||
The app is now bootable, but you're not quite there yet. By default, Rails
|
||||
expects a database to be running on `localhost` - so you need to point it at the
|
||||
`db` container instead. You also need to change the database and username to
|
||||
align with the defaults set by the `postgres` image.
|
||||
|
||||
Replace the contents of `config/database.yml` with the following:
|
||||
|
||||
```yaml
|
||||
default: &default
|
||||
adapter: postgresql
|
||||
encoding: unicode
|
||||
host: db
|
||||
username: postgres
|
||||
password: password
|
||||
pool: 5
|
||||
|
||||
development:
|
||||
<<: *default
|
||||
database: myapp_development
|
||||
|
||||
|
||||
test:
|
||||
<<: *default
|
||||
database: myapp_test
|
||||
```
|
||||
|
||||
You can now boot the app with [docker compose up](https://docs.docker.com/engine/reference/commandline/compose_up/).
|
||||
If all is well, you should see some PostgreSQL output:
|
||||
|
||||
```console
|
||||
$ docker compose up
|
||||
|
||||
rails_db_1 is up-to-date
|
||||
Creating rails_web_1 ... done
|
||||
Attaching to rails_db_1, rails_web_1
|
||||
db_1 | PostgreSQL init process complete; ready for start up.
|
||||
db_1 |
|
||||
db_1 | 2018-03-21 20:18:37.437 UTC [1] LOG: listening on IPv4 address "0.0.0.0", port 5432
|
||||
db_1 | 2018-03-21 20:18:37.437 UTC [1] LOG: listening on IPv6 address "::", port 5432
|
||||
db_1 | 2018-03-21 20:18:37.443 UTC [1] LOG: listening on Unix socket "/var/run/postgresql/.s.PGSQL.5432"
|
||||
db_1 | 2018-03-21 20:18:37.726 UTC [55] LOG: database system was shut down at 2018-03-21 20:18:37 UTC
|
||||
db_1 | 2018-03-21 20:18:37.772 UTC [1] LOG: database system is ready to accept connections
|
||||
```
|
||||
|
||||
Finally, you need to create the database. In another terminal, run:
|
||||
|
||||
```console
|
||||
$ docker compose run web rake db:create
|
||||
Starting rails_db_1 ... done
|
||||
Created database 'myapp_development'
|
||||
Created database 'myapp_test'
|
||||
```
|
||||
|
||||
### View the Rails welcome page!
|
||||
|
||||
That's it. Your app should now be running on port 3000 on your Docker daemon.
|
||||
|
||||
On Docker Desktop for Mac and Docker Desktop for Windows, go to `http://localhost:3000` on a web
|
||||
browser to see the Rails Welcome.
|
||||
|
||||
|
||||
|
||||
### Stop the application
|
||||
|
||||
To stop the application, run [docker compose down](https://docs.docker.com/engine/reference/commandline/compose_down/) in
|
||||
your project directory. You can use the same terminal window in which you
|
||||
started the database, or another one where you have access to a command prompt.
|
||||
This is a clean way to stop the application.
|
||||
|
||||
```console
|
||||
$ docker compose down
|
||||
|
||||
Stopping rails_web_1 ... done
|
||||
Stopping rails_db_1 ... done
|
||||
Removing rails_web_run_1 ... done
|
||||
Removing rails_web_1 ... done
|
||||
Removing rails_db_1 ... done
|
||||
Removing network rails_default
|
||||
|
||||
```
|
||||
|
||||
### Restart the application
|
||||
|
||||
To restart the application run `docker compose up` in the project directory.
|
||||
|
||||
### Rebuild the application
|
||||
|
||||
If you make changes to the Gemfile or the Compose file to try out some different
|
||||
configurations, you need to rebuild. Some changes require only
|
||||
`docker compose up --build`, but a full rebuild requires a re-run of
|
||||
`docker compose run web bundle install` to sync changes in the `Gemfile.lock` to
|
||||
the host, followed by `docker compose up --build`.
|
||||
|
||||
Here is an example of the first case, where a full rebuild is not necessary.
|
||||
Suppose you simply want to change the exposed port on the local host from `3000`
|
||||
in our first example to `3001`. Make the change to the Compose file to expose
|
||||
port `3000` on the container through a new port, `3001`, on the host, and save
|
||||
the changes:
|
||||
|
||||
```yaml
|
||||
ports:
|
||||
- "3001:3000"
|
||||
```
|
||||
|
||||
Now, rebuild and restart the app with `docker compose up --build`.
|
||||
|
||||
Inside the container, your app is running on the same port as before `3000`, but
|
||||
the Rails Welcome is now available on `http://localhost:3001` on your local
|
||||
host.

# Quickstart: Compose and WordPress
|
||||
|
||||
You can use Docker Compose to easily run WordPress in an isolated environment
|
||||
built with Docker containers. This quick-start guide demonstrates how to use
|
||||
Compose to set up and run WordPress. Before starting, make sure you have
|
||||
[Compose installed](https://docs.docker.com/compose/install/).
|
||||
|
||||
## Define the project
|
||||
|
||||
1. Create an empty project directory.
|
||||
|
||||
You can name the directory something easy for you to remember.
|
||||
This directory is the context for your application image. The
|
||||
directory should only contain resources to build that image.
|
||||
|
||||
This project directory contains a `docker-compose.yml` file which
|
||||
is complete in itself for a good starter wordpress project.
|
||||
|
||||
>**Tip**: You can use either a `.yml` or `.yaml` extension for
|
||||
this file. They both work.
|
||||
|
||||
2. Change into your project directory.
|
||||
|
||||
For example, if you named your directory `my_wordpress`:
|
||||
|
||||
```console
|
||||
$ cd my_wordpress/
|
||||
```
|
||||
|
||||
3. Create a `docker-compose.yml` file that starts your
|
||||
`WordPress` blog and a separate `MySQL` instance with volume
|
||||
mounts for data persistence:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
db:
|
||||
# We use a mariadb image which supports both amd64 & arm64 architecture
|
||||
image: mariadb:10.6.4-focal
|
||||
# If you really want to use MySQL, uncomment the following line
|
||||
#image: mysql:8.0.27
|
||||
command: '--default-authentication-plugin=mysql_native_password'
|
||||
volumes:
|
||||
- db_data:/var/lib/mysql
|
||||
restart: always
|
||||
environment:
|
||||
- MYSQL_ROOT_PASSWORD=somewordpress
|
||||
- MYSQL_DATABASE=wordpress
|
||||
- MYSQL_USER=wordpress
|
||||
- MYSQL_PASSWORD=wordpress
|
||||
expose:
|
||||
- 3306
|
||||
- 33060
|
||||
wordpress:
|
||||
image: wordpress:latest
|
||||
volumes:
|
||||
- wp_data:/var/www/html
|
||||
ports:
|
||||
- 80:80
|
||||
restart: always
|
||||
environment:
|
||||
- WORDPRESS_DB_HOST=db
|
||||
- WORDPRESS_DB_USER=wordpress
|
||||
- WORDPRESS_DB_PASSWORD=wordpress
|
||||
- WORDPRESS_DB_NAME=wordpress
|
||||
volumes:
|
||||
db_data:
|
||||
wp_data:
|
||||
```
|
||||
|
||||
> **Notes**:
|
||||
>
|
||||
* The docker volumes `db_data` and `wordpress_data` persists updates made by WordPress
|
||||
to the database, as well as the installed themes and plugins. [Learn more about docker volumes](https://docs.docker.com/storage/volumes/)
|
||||
>
|
||||
* WordPress Multisite works only on ports `80` and `443`.
|
||||

|
||||
|
||||
### Build the project
|
||||
|
||||
Now, run `docker compose up -d` from your project directory.
|
||||
|
||||
This runs [`docker compose up`](https://docs.docker.com/engine/reference/commandline/compose_up/) in detached mode, pulls
|
||||
the needed Docker images, and starts the wordpress and database containers, as shown in
|
||||
the example below.
|
||||
|
||||
```console
|
||||
$ docker compose up -d
|
||||
|
||||
Creating network "my_wordpress_default" with the default driver
|
||||

||||

||||

||||

||||

|
||||
Status: Downloaded newer image for wordpress:latest
|
||||
Creating my_wordpress_db_1
|
||||
Creating my_wordpress_wordpress_1
|
||||
```
|
||||
|
||||
> **Note**: WordPress Multisite works only on ports `80` and/or `443`.
|
||||
If you get an error message about binding `0.0.0.0` to port `80` or `443`
|
||||
(depending on which one you specified), it is likely that the port you
|
||||
configured for WordPress is already in use by another service.
|
||||
|
||||
### Bring up WordPress in a web browser
|
||||
|
||||
At this point, WordPress should be running on port `80` of your Docker Host,
|
||||
and you can complete the "famous five-minute installation" as a WordPress
|
||||
administrator.
|
||||
|
||||
> **Note**: The WordPress site is not immediately available on port `80`
|
||||
because the containers are still being initialized and may take a couple of
|
||||
minutes before the first load.
|
||||
|
||||
If you are using Docker Desktop for Mac or Docker Desktop for Windows, you can use
|
||||
`http://localhost` as the IP address, and open `http://localhost:80` in a web
|
||||
browser.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### Shutdown and cleanup
|
||||
|
||||
The command [`docker compose down`](https://docs.docker.com/engine/reference/commandline/compose_down/) removes the
|
||||
containers and default network, but preserves your WordPress database.
|
||||
|
||||
The command `docker compose down --volumes` removes the containers, default
|
||||
network, and the WordPress database.

# Compose sample application
|
||||
|
||||
|
||||
|
||||
This sample demonstrates a WebAssembly (Wasm) microservice written in Rust. It subscribes to a Kafka queue topic on a Redpanda server, and then transforms and saves each message into a MySQL (MariaDB) database table. The microservice is compiled into Wasm and runs in the WasmEdge runtime, which is a secure and lightweight alternative to natively compiled Rust apps in Linux containers.
|
||||
|
||||
## Use with Docker Development Environments
|
||||
|
||||
You will need a version of Docker Desktop or Docker CLI with Wasm support.
|
||||
|
||||
* [Install Docker Desktop + Wasm (Beta)](https://docs.docker.com/desktop/wasm/)
|
||||
* [Install Docker CLI + Wasm](https://github.com/chris-crone/wasm-day-na-22/tree/main/server)

The compose file defines an application with three services `redpanda`, `etl` and `db`. The `redpanda` service is a Kafka-compatible messaging server that produces messages in a queue topic. The `etl` service, in the WasmEdge container that subscribes to the queue topic and receives incoming messages. Each incoming message is parsed and stored in the `db` MySQL (MariaDB) database server.
|
||||
|
||||
## Deploy with docker compose
|
||||

||||
```bash
|
||||
$ docker compose up -d

|
||||
```
|
||||
|
||||
After the application starts,
|
||||
log into the Redpanda container and send a message to the queue topic `order` as follows.
|
||||
|
||||
```bash
|
||||
$ docker compose exec redpanda /bin/bash
|
||||
redpanda@1add2615774b:/$ cd /app
|
||||
redpanda@1add2615774b:/app$ cat order.json | rpk topic produce order
|
||||
Produced to partition 0 at offset 0 with timestamp 1667922788523.
|
||||
```
|
||||
|
||||
To see the data in the database container, you can use the following commands.
|
||||
|
||||
```bash
|
||||
$ docker compose exec db /bin/bash
|
||||

# Compose sample application
|
||||
|
||||
|
||||
|
||||
This sample demonstrates a web application with a WebAssembly (Wasm) microservice, written in Rust. The Wasm microservice is an HTTP API connected to a MySQL (MariaDB) database. The API is invoked via from JavaScript in a web interface serving static HTML. The microservice is compiled into WebAssembly (Wasm) and runs in the WasmEdge Runtime, a secure and lightweight alternative to natively compiled Rust apps in Linux containers. Checkout [this article](https://blog.logrocket.com/rust-microservices-server-side-webassembly/) or [this video](https://www.youtube.com/watch?v=VSqMPFr7SEs) to learn how the Rust code in this microservice works.
|
||||
|
||||
## Use with Docker Development Environments
|
||||
|
||||
You will need a version of Docker Desktop or Docker CLI with Wasm support.
|

|
||||
|
||||
The compose file defines an application with three services `frontend`, `backend` and `db`. The `frontend` is a simple Nginx server that hosts static web pages that access the `backend` web service, in the WasmEdge container, via HTTP port 8080. When deploying the application, docker compose maps port 8090 of the `frontend` service container to port 8090 of the host as specified in the file. Make sure that ports 8090 and 8080 on the host are not already being used.
|
||||
|
||||
## Deploy with docker compose
|
||||
|
||||
```bash
|
||||
$ docker compose up -d
|
||||
...
|
||||
⠿ Network wasmedge-mysql-nginx_default Created

||||
⠿ Container wasmedge-mysql-nginx-db-1 Created
|
||||
⠿ Container wasmedge-mysql-nginx-frontend-1 Created
|
||||
⠿ Container wasmedge-mysql-nginx-backend-1 Created
|
||||
```
|
||||
|
||||
## Expected result
|
||||
|
||||
```bash
|
||||
$ docker compose ps
|
||||
NAME COMMAND SERVICE STATUS PORTS
|
||||
wasmedge-mysql-nginx-backend-1 "order_demo_service.…" backend running 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp
|
||||

|
||||
wasmedge-mysql-nginx-frontend-1 "/docker-entrypoint.…" frontend running 0.0.0.0:8090->80/tcp, :::8090->80/tcp
|
||||
```
|
||||
|
||||
After the application starts, go to `http://localhost:8090` in your web browser to display the web frontend.
|
||||
|
||||
### Using the API with `curl`
|
||||
|
||||
As an alternative to the web frontend, you can use `curl` to interact with the WasmEdge API directly (the `backend` service).
|
||||
|
||||
When the WasmEdge web service receives a GET request to the `/init` endpoint, it would initialize the database with the `orders` table.
|
||||
|
||||
```bash
|
||||
curl http://localhost:8080/init
|
||||
```
|
||||
|
||||
When the WasmEdge web service receives a POST request to the `/create_order` endpoint, it extracts the JSON data from the POST body and inserts an `Order` record into the database table.
|
||||
To insert multiple records, use the `/create_orders` endpoint and POST a JSON array of `Order` objects:
|
||||
|
||||
```bash
|
||||
curl http://localhost:8080/create_orders -X POST -d @db/orders.json
|
||||
```
|
||||
|
||||
When the WasmEdge web service receives a GET request to the `/orders` endpoint, it gets all rows from the `orders` table and return the result set in a JSON array in the HTTP response.
|
||||
|
||||
```bash
|
||||
curl http://localhost:8080/orders
|
||||
```
|
||||
|
||||
When the WasmEdge web service receives a POST request to the `/update_order` endpoint, it extracts the JSON data from the POST body and update the `Order` record in the database table that matches the `order_id` in the input data.
|
||||
|
||||
```bash
|
||||
curl http://localhost:8080/update_order -X POST -d @db/update_order.json
|
||||
```
|
||||
|
||||
When the WasmEdge web service receives a GET request to the `/delete_order` endpoint, it deletes the row in the `orders` table that matches the `id` GET parameter.
|
||||
|
||||
```bash
|
||||
curl http://localhost:8080/delete_order?id=2
|
||||
```
