Which Docker commands list running containers and show a container's logs?

Options

1. docker ps and docker logs <container> (Correct option)
2. docker list and docker show
3. docker images and docker run
4. docker build and docker push

Answer

docker ps and docker logs <container>

Why

Everyday Docker commands:

• docker build -t myapp .: build an image from a Dockerfile.
• docker run -d -p 8080:8080 --name web myapp: start a container in the background.
• docker ps (add -a for stopped ones): list containers.
• docker logs -f web: follow the output.
• docker exec -it web sh: open a shell inside it.
• docker stop web / docker rm web: stop and remove it.
• docker images: list local images.

Remember

ps = list, logs = output, exec = shell inside.

Key terms

• Container
• Docker image
• Docker CLI
• Dockerfile
