Docker

Important Commands

All of our tooling will be available in Docker containers. This means that, unless you want to install node, go, a DB and possibly other tools locally, you should get familiar with the basics:

• Running a container: docker run <image name>. MANY options, such as -v for mounts, -p for ports, --name for name, --rm to remove it when it exits, -it to attach, etc
• Updating / pulling an image: docker pull <image name>
• View running containers: docker ps (add -a to also show stopped containers)
• View images: docker image ls (add -a to also show untagged images (i.e. old ones in most cases))
• Stop container: docker stop <container name or hash>
• Start existing container: docker start <container name or hash>
• Delete container: docker rm <container name or hash>
• Delete image: docker rmi <image name or hash>

Docker compose

To make your life a bit easier, I will be providing a docker-compose.yml file.

In that case, instead of running all the docker commands above on a regular basis (which will be quite a bit longer than what you can see there, but I'll also provide those), you can rely on running docker compose up -d in the folder where that file is located to start everything you need and docker compose down to clean up after the fact. To update the images, run docker compose pull to update the images.

To periodically clean up dangling images, run

docker image prune
