From a single server MVP to scale easy with Portainer
We assume you already have you web-app running within a container
Select your orchestration (what is best practice, what are reasons, what are limits ???)
- Kubernetes
- Docker Swarm
10-100 server : Docker Swarm
50-200 server: microk8s (easy as docker swarm, but prepare for further growth ???)
100-100.000: kubernetes
Setup infrastructure (swarm or microk8s)
Launch servers (virtual or bare metal)
Create master
Join further nodes
Launch Portainer
Launch reverse proxy via Portainer
The reverse proxy will automatically load balance all incoming requests to the web-app containers
The proxy will hot reload when containers change, not interrupt ongoing and long-running requests (?)
The proxy can automatically forward to services based on sub-domains and/or paths via labels (?)
Launch services (web-app and others)
Launch you services with Portainer, set labels for sub-domain and/or path
Example: www (wordpress), api (nodejs) (?)
Database: only one instance per server on dedicated servers
Scale up
Check metrics
Easily scale services up and down, add more servers
7. b. Manage credentials, pass them to the web-app so it can connect to the database.
