Portainer as Docker Compose file

by

Updating portainer becomes:
docker compose down
docker pull portainer/portainer-ce:latest
docker compose up -d

version: '3.0'
services:
  portainer:
    container_name: portainer
    hostname: portainer
    command: --sslcert /certs/lan.fullchain --sslkey /certs/lan.key
    image: portainer/portainer-ce:latest
    restart: unless-stopped
    network_mode: bridge
    environment:
      - "TZ=EST5EDT"
    ports:
      - 9443:9443
    volumes:
      - data:/data
      - /ssl/lancerts:/certs:ro
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock

volumes:
  data:

Paste the above into a docker-compose.yml file, I placed mine in a ‘portainer’ folder inside my home directory. Then just run docker compose up -d

I use a folder on my system, /ssl/lancerts, which I map to /certs inside the container. You will have to modify your certificate locations in the volumes section, and the command line towards the top of the compose file. If you are not using SSL, then simply comment out or remove the command line at the top of the compose file and remove the volume mapping.
