Docker Documentation

Why use docker?

Setup

Allow user to run docker commands (without sudo)

sudo usermod -aG docker jonathan

Dockerfile

https://medium.com/bb-tutorials-and-thoughts/docker-a-beginners-guide-to-dockerfile-with-a-sample-project-6c1ac1f17490 Maybe put run in Dockerfile like this?

# Start container
JUPY_CONTAINER_NAME="jupytest"
IMAGE="jupyter/base-notebook:latest"

HOST_WORK=`pwd`
CONTAINER_WORK=/home/jovyan/work

docker run -it --rm \
  -p 8888:8888 \
  -v "${HOST_WORK}":"${CONTAINER_WORK}" \
  $IMAGE start-notebook.sh

Might try Docker-compose multiple containers (ie. train and convert_to_Darknet) Run docker-compose up

Build & run container

docker build -t jonathan/test /media/Data/sync/gw/research/power_mgmt_infra/src/sorter/keras/
docker run -it --rm -p 8888:8888 -v /media/Data/sync/gw/research:/home/jovyan/work jonathan/test

docker run [options] (docs)

• --rm removes container after completion
• --name container_name names container
• -d runs container as daemon (doesn't block terminal)
  • use docker start container_name and docker stop container_name
• -it runs container in interactive mode (use to get notebook URL)
• -v "$PWD":/home/jovyan/work mounts current director in container to allow read/write. jovyan is the default user for jupyter notebooks

Maybe run -td? Run as daemon, but need URL with token.

Other commands

List images and containers.

docker image ls
docker ps -a

Stop and remove all containers.

docker stop $(docker ps -a -q)
docker rm $(docker ps -a -q)

Remove image, image with no tag, force remove all.

docker rmi image_name
docker rmi $(docker images -f dangling=true -q)
docker rmi $(docker images -q) --force

Issues

• Permission denied from Jupyter Notebook

  mkdir test
  ls -l test
  chgrp 100 test
  chmod g+w test
  ls -l test
  

Resources

• Jupyter Docker Stacks
• Run Docker in WSL
