Docker Cheat sheet
It seems like everyone has their own Docker Cheatsheet nowadays, and I thought I'd add one more into the mix. I've noted down some handy commands I use most often when I work on Docker-related tasks.
Status of docker
A quick and easy way to see an overview of docker on your machine. E.g. how many containers and images have been downloaded and their status.
Build Docker image
This is only required if we want to create a Docker image from a Dockerfile.
docker build . docker build -t newImage . // tag the image
Run Docker container
Once we create our own Docker image or pull one from a registry, we'd want to run it on our machine.
docker run alpine:3.9 docker run -d alpine:3.9 // detached mode docker run -it alpine:3.9 /bin/bash // interactive mode docker run -v "$(pwd)/src:/app" alpine:3.9 // map volume docker run -p 8080:8000 alpine:3.9 // map port
Stop and remove all Docker containers
Wipe all containers. This is especially handy after playing around with a bunch of ideas on the development machine.
docker stop $(docker ps -aq) // OR docker stop $(docker ps -a -q) docker rm $(docker ps -aq) // OR docker rm $(docker ps -a -q) docker rm -f $(docker ps -aq) // doing it all in one line with force remove
Remove all Docker images
I personally prefer to have no Docker images on my machine unless they are in use. This is a brutal but easy way to get rid of all the random images that are taking up precious storage space.
docker rmi $(docker images -q)
