Portability

Build

Check images available locally:

$ docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
imageName           tagName             someId              randomDate          someMBs

Build an image from a dockerfile:

$ docker build -t myapp:1.0 .

Delete an image from the local image store:

$ docker rmi alpine:3.4

Ship

Docker Hub

Cloud-based registry service which allows you to link to code repositories, build your images and test them, stores manually pushed images

Ship

Login with your docker hub account:

$ docker login

Retag a local image with a new image name and tag

$ docker tag alpine:3.4 myrepo/myalpine:3.4

Push an image to the registry:

$ docker push myrepo/myalpine:3.4

Grab an image from remote registry:

$ docker pull alpine:3.4

Run

Run a container:

$ docker run

                --rm
                -it
                --name containerName
                -p 5000:80
                -v ~/dev:/code
                alpine:3.4
                /bin/sh

$ docker stop containerName
$ docker kill containerName

Stop running a container:
