docker build -t <name_you_want_for_the_image> . –no-cache

List local images of our PC

docker images

Remove Images

Delete an Image:

docker rmi <image_name>

Please remove all images that are not currently used by any running containers:

docker image prune

Upload/Download images to/from DockerHub Registry

Upload

Login into DockerHub on your terminal:

docker login -u <username>

Publish an image to Docker Hub with your username:

docker push <username>/<image_name>

Download

Search for an image on DockerHub:

docker search <image_name>

Download (pull) an image from Docker Hub:

docker pull <image_name>

Run/Stop/Start a container (basic)

See running containers on the machine:

docker ps

Create and run a container from an image, with a custom name:

docker run --name <container_name> <image_name>

Run a container in the background

docker run -d <image_name>

Start or stop an existing container:

docker start|stop <container_name> (or <container-id>)

Remove a stopped container:

docker rm <container_name>

Run a container given an image (advanced)

Map ports of your host to the container:

docker run --name <container_name> -p <host_post>:<container_port> <image_name>

Mount a volume from host to container:

docker run -v <volume-name>:<path-in-container-where-volume-is-mounted> <image-name>

Pass environment variables:

docker run -e MY_ENV_VAR='whatever' <image_name>

Misc. operations

Open a shell inside a running container (in this case our shell is sh):

docker exec -it <container_identifier> sh

Fetch and follow the logs of a container:

docker logs -f <container_name>

To inspect (see all the metadata) of a running container:

docker inspect <container_name> (or <container_id>)

View resource usage stats of the containers:
