Docker containers management

Docker container commands

✔️ Create container from an image

docker container run <image>

# remove container after command exits
docker container run --rm <image>

# detach (run in background) and map host port 3000 to container port 80
docker container run -d -p 3000:80 <image> 

# name container and override CMD/ENTRYPOINT Dockerfile directive with interactive shell/pseudo tty (-i -t)
docker container run --name <name> -i -t <image> /bin/sh

✔️ List all containers (running and stopped)

docker container ls -a

✔️ Stop container

# normal container exit code is zero
docker container stop <container>

✔️ Restarts stopped container (run in background, interactive, attach : overrides interactive)

# start in background
docker container start <container>

# start in interactive mode
docker container start -i <container>

# attach container stdout / stderr to current shell
docker container start -a <container>

✔️ Print container logs

# prints CMD/ENTRYPOINT Dockerfile directive output since container startup
docker logs <container id>

✔️ Enter a running container (shell may vary)

# switch the container to interactive mode and start a shell
docker exec -i -t <container> /bin/bash

✔️ Gracefully stop container

# graceful shutdown (SIGTERM)
docker container stop <container>

# forced shutdown (SIGKILL)
docker container kill <container>

✔️ Delete a stopped container (specified, all stopped)

# delete a specific container
docker container rm <container>

# delete all stopped containers
docker container prune -f
