Portainer

In the Army, we have “Command Posts.” Portainer is your Command Post for Docker. It gives you a visual overview of your “digital troops” (containers) and lets you deploy them with ease.

Description

Portainer is a powerful, open-source tool set that allows you to easily build and manage containers in Docker, Swarm, Kubernetes, and Azure ACI.

It’s a “must-have” for any home lab running more than a couple of containers. It makes managing stacks (docker-compose) much more manageable.

Knowledge Check

• Do you have the agent installed on your remote nodes?
• Are you using the Business Edition (free for up to 3 nodes) or the Community Edition?

Common Pitfalls

• Port Conflicts: Ensure ports 9000 (HTTP) or 9443 (HTTPS) are not already in use on your host.
• Volume Persistence: Always map /data to a persistent volume so you don’t lose your configuration on restart.
