Run a Docker image as a container

Question

After building a Docker image from a dockerfile, I see the image was built successfully, but what do I do with it? Shouldn\'t i be able to run it as a container

Answer 1

To view a list of all images on your Docker host, run:

  $ docker images
   REPOSITORY          TAG           IMAGE ID            CREATED             SIZE
   apache_snapshot     latest        13037686eac3        22 seconds ago      249MB
   ubuntu              latest        00fd29ccc6f1        3 weeks ago         111MB

Now you can run the Docker image as a container in interactive mode:

   $ docker run -it apache_snapshot /bin/bash

OR if you don't have any images locally,Search Docker Hub for an image to download:

    $ docker search ubuntu

Pull the Docker image from a repository with the docker pull command:

     $ docker pull ubuntu

Run the Docker image as a container:

     $ docker run -it ubuntu /bin/bash
