Very Basic Docker Commands Cheat Sheet

If you ever needed a quick list of Docker commands, here you go.. 1. Check that Docker is installed docker --version Shows the installed Docker version. 2. Run your first container docker run hello-world Pulls the official test image (if needed) and runs it. You should see a “Hello from Docker!” message. 3. See running containers docker ps Lists containers that are currently running. Use docker ps -a to also show stopped ones. 4. See downloaded images docker images Shows every image on your machine (name, tag, size, ID). 5. Stop a running container docker stop CONTAINER_ID Gracefully stops a container. Get the ID from docker ps . 6. Remove a stopped container docker rm CONTAINER_ID Deletes a container that is already stopped. 7. Force stop and remove docker rm -f CONTAINER_ID Force-stops the container (if it’s still running) and removes it in one step.
