Advanced Docker commands

Docker install

It is best to follow the official Docker instructions for installation.

Ubuntu

Direct links:

Warning: Check first what every command does before executing. Commands might be outdated.

Add current user to group docker on Linux systems. This prevents the need of typing sudo before every docker command.

sudo usermod -a -G docker $USER

Docker machine (ip):

base=https://github.com/docker/machine/releases/download/v0.16.0 &&
  curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker-machine &&
  sudo install /tmp/docker-machine /usr/local/bin/docker-machine

Docker machine bash completion:

base=https://raw.githubusercontent.com/docker/machine/v0.16.0
  for i in docker-machine-prompt.bash docker-machine-wrapper.bash docker-machine.bash
  do
    sudo wget "$base/contrib/completion/bash/${i}" -P /etc/bash_completion.d
  done

Docker own OpenFace .csv (untested)

If you want to use your own OpenFace .csv, you've obtained by running some video through OpenFace, in combination with Docker, you will need to do:
  • Copy file from host to container: docker cp foo.csv facsvatar_facsfromcsv:/openface/*your_folder/foo.csv
  • Go inside Docker container: docker-compose exec facsvatar_facsfromcsv bash
  • Inside container: python main.py --pub_ip facsvatar_bridge --csv_folder openface/your_folder --csv_arg -1

Useful Docker commands

sudo usermod -a -G docker $USER  # add current user to group docker on Linux systems (Ubuntu)

docker build . -t foo/bar  # build docker image
docker run -it foo/bar  # run build docker image and enter interactive mode
docker run -p 5550:5550 -it foo/bar  # same as above with mapping Docker port to host
docker-compose up  # run docker-compose.yml
docker-compose build / docker-compose up --build  # rebuild images in docker-compose.yml

docker image ls  # show docker images
docker container ls  # show docker containers
docker exec -it pyzmq-docker_pub_1  # enter bash in container
docker attach pyzmq-docker_sub_1  # get
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' pyzmq-docker_sub_1  # get ip of container

To detach the tty without exiting the shell, use the escape sequence Ctrl+p + Ctrl+q

docker stop $(docker ps -a -q)  # stop all CONTAINERS
docker rm $(docker ps -a -q)  # remove all CONTAINERS
docker rm $(docker images -q)  # remove all IMAGES
You can’t perform that action at this time.
