I love the terminal. But I don't love typing docker ps twenty times a day to check container health.
Portainer is the GUI that Docker forgot to build. It lets you manage stacks, containers, images, and networks from a web interface. It's essential for any homelab or small production environment.
The Installation
It's literally one command (or one Compose file).
version: '3'
services:
portainer:
image: portainer/portainer-ce:latest
container_name: portainer
restart: always
ports:
- "8000:8000"
- "9443:9443"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- portainer_data:/data
volumes:
portainer_data:
Why Use It?
- Visual Logs: Click a container, click "Logs". No more
docker logs -f --tail 100 container_name. - Stacks: You can paste your
docker-compose.yamldirectly into the UI and deploy it. - Cleanup: It helps you find and delete unused images and volumes that are eating your disk space.
Security Note
Portainer has root access to your Docker socket. Protect it. Put it behind a reverse proxy (like Traefik) and use strong passwords.
