Install Portainer

Portainer documentation https://docs.portainer.io/start/install-ce/server/docker/linux#deployment

1. Create network

   docker network create \
    --driver=bridge \
    --subnet=172.20.0.0/16 \
    --ip-range=172.20.0.0/24 \
    --gateway=172.20.0.1 \
    default-network

2. Stop current Portainer

   docker stop portainer

3. Remove current Portainer

   docker rm portainer

4. Pull latest image

   docker pull portainer/portainer-ce:latest

5. Run Portainer. Command maps certificates from mounted directory to Portainer default files

   docker run -d -p 8000:8000 -p 9000:9000 -p 9443:9443 \
   --name portainer --restart=always --network=default-network \
   -v /config/cert/certificate.pem:/certs/portainer.crt -v /config/cert/key.pem:/certs/portainer.key \
   -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

Common issues

• Bad Gateway from Cloudflare to Portainer is due to fact that Portainer container is not in same network with Cloudflared.

• Startup fails due to conflict with port 8000

  docker run -d -p 9000:9000 -p 9443:9443 \
  --name portainer --restart=always --network=default-network \
  -v /config/cert/certificate.pem:/certs/portainer.crt -v /config/cert/key.pem:/certs/portainer.key \
  -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest
