Portainer GUI

Prereq

Already deployed:

✅ Docker swarm cluster with persistent shared storage

✅ Traefik

Portainer is a lightweight UI for visualizing your docker environment. It also happens to integrate well with Docker Swarm clusters, which makes it a great fit for our stack.

It's a great addition to any stack, especially if you're just starting your containerization journey!

Create Persistent Volume​

sudo mkdir /var/data/portainer
cd /var/data/portainer

Stack​

sudo micro portainer-stack.yaml
note

If you use traefik to expose portainer then uncomment labels and change ports section.
