Docker Setup On Linux Server¶

Networking/Environments¶

By default when mapping a port on Docker, it will bind to all the interfaces, this is fine for home user behind a firewall but not suitable for VPS as all ports will be wide open on the internet. To fix this, only bind to tailscale IP when mapping ports. For convenience, setup PUID and PGID for future container setups.

• put this in the bashrc for automatic loading of Tailscale IP variable
• now the docker compose, all the environment variables can be used.

export TAILSCALE_IP=$(tailscale ip --4)
export PUID=$(id -u)
export PGID=$(id -g)

    ports:

      - ${TAILSCALE_IP}:8080:8080

Logs¶

Change this in /etc/docker/daemon.json

{
  "log-driver": "local",
  "log-opts": {
    "max-size": "10m",
    "max-file": 10
  }
