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.
