Docker Tricks

Base directory for mounting

mkdir -p ~/Projects/docker
cd ~/Projects/docker

Dockers with Proxy

Considering that $PWD is the base directory

Running Traefik as HTTP Proxy server

mkdir traefik
curl https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml > traefik/traefik.toml
docker run -d \
  --name traefik \
  --publish 80:80 \
  --mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock \
  --mount type=bind,source=$PWD/traefik/traefik.toml,target=/traefik.toml \
  --label traefik.port=8080 \
  --label traefik.frontend.rule=Host:monitor.localhost \
  traefik \
  --docker \
  --docker.domain=localhost \
  --docker.watch \
  --web

You can now use http://monitor.localhost to observe your requests.

Portainer as Docker GUI

mkdir portainer
docker run -d \
  --name portainer \
  --mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
  --mount type=bind,src=$PWD/portainer,dst=/data \
  --label traefik.port=9000 \
  portainer/portainer \
  -H unix:///var/run/docker.sock

You can now use http://portainer.localhost to manage your Docker containers.

MySQL

mkdir mysql
docker run -d \
  --name mysql \
  -p 3306:3306 \
  -v $PWD/mysql:/var/lib/mysql \
  -e MYSQL_ROOT_PASSWORD="MY ROOT PASSWORD" \
  --memory 384000000 \
  mysql:5.7

Memory: Limit memory usage in bytes

It exposes port 3306 to your host computer (and potentially to your network if your host is not firewalled). Now you can install a compatible mysql client in your host OS.

For ArchLinux: pacman -S percona-server-clients or pacman -S mariadb-clients
