Build an Image from a Dockerle

docker build -t <image_name>

Build an Image from a Dockerle without the cache

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

List local images

docker images

Delete an Image

docker rmi <image_name>

Remove all unused images

docker image prune

docker login -u <username>

Publish an image to Docker Hub

docker push <username>/<image_name>

Search Hub for an image

docker search <image_name>

Pull an image from a Docker Hub

docker pull <image_name>

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

docker run --name <container_name> <image_name>

Run a container with and publish a container’s port(s) to the host.

docker run -p <host_port>:<container_port> <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>

Open a shell inside a running container:

docker exec -it <container_name> sh

Fetch and follow the logs of a container:

docker logs -f <container_name>

To inspect a running container:

docker inspect <container_name> (or <container_id>)

To list currently running containers:

docker ps

List all docker containers (running and stopped):

docker ps --all

GENERAL COMMANDS

Docker provides the ability to package and run an application in a loosely isolated environment called a container.

The isolation and security allows you to run many containers simultaneously on a given host. Containers are

lightweight and contain everything needed to run the application, so you do not need to rely on what is currently

installed on the host. You can easily share containers while you work, and be sure that everyone you share with gets

the same container that works in the same way.

IMAGES

Docker images are a lightweight, standalone, executable package

of soware that includes everything needed to run an application:

code, runtime, system tools, system libraries and settings.

DOCKER HUB

Docker Hub is a service provided by Docker for nding and sharing

container images with your team. Learn more and nd images

at https://hub.docker.com

CONTAINERS

A container is a runtime instance of a docker image. A container

will always run the same, regardless of the infrastructure.

Containers isolate soware from its environment and ensure

that it works uniformly despite dierences for instance between

development and staging.

Start the docker daemon

docker -d
