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

The specific way to run it depends on whether you gave the image a tag/name or not.

$ docker images
REPOSITORY          TAG                 ID                  CREATED             SIZE
ubuntu              12.04               8dbd9e392a96        4 months ago        131.5 MB (virtual 131.5 MB)

With a name (let's use Ubuntu):

$ docker run -i -t ubuntu:12.04 /bin/bash

Without a name, just using the ID:

$ docker run -i -t 8dbd9e392a96 /bin/bash

Please see Docker run reference for more information.

For those who had the same problem as well  but encountered an error like  rpc error  code   2 desc   oci runtime error  exec failed  container linux go 247  starting container process caused  exec    bash    executable file not found in  PATH    I added an entry point that was worked for me   docker run -it --entrypoint  bin sh for the images without Bash   Example  from the approved example    run -it --entrypoint  bin sh ubuntu 12 04   Reference  https   gist github com mitchwongho 11266726

You can see your available images using   docker images   Then you can run in detached mode so your terminal is still usable  You have several options to run it using a repository name  with or without a tag  or image ID   docker run -d repository docker run -d repository tag docker run -d image id   Then you can check your container is running using  docker ps   docker ps gives you a container ID  You can use it or just the 2 3 first characters to go into your container using   docker exec -it container id  bin bash   And you can stop it using docker stop container id and docker rm container id   You can also run your container with -rm arguments so if you stop your container it will automatically be removed

I had the same problem  I ran my Docker image  and it created a container with a specific CONTAINER ID  I wanted to work with the same container   First run your Docker image   docker run -it -p 8888 8888 -p 6006 6006 -v     host waleedka modern-deep-learning   Then list all the containers you have made   sudo docker ps -a   And select the container you want to work with  mine is 167ddd6d7f15    sudo docker start -ai 167ddd6d7f15

Do the following steps      docker images  You will get a list of all local Docker images with the tags specified    docker run image name tag name  If you didn t specify tag name it will automatically run an image with the  latest  tag   Instead of image name  you can also specify an image ID  no tag name

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     NAME                            DESCRIPTION             STARS  OFFICIAL  AUTOMATED     ubuntu                          Ubuntu is a Debian      6759    OK             dorowu ubuntu-desktop-lxde-vnc  Ubuntu with openss      141               OK      rastasheep ubuntu-sshd          Dockerized SSH ser      114               OK      ansible ubuntu14 04-ansible     Ubuntu 14 04 LTS w      88                OK      ubuntu-upstart                  Upstart is an even      80      OK    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

Since you have created an image from the Dockerfile  the image currently is not in active state  In order to work you need to run this image inside a container   The   docker images command describes how many images are currently available in the local repository  and  docker ps -a   shows how many containers are currently available  i e  the list of active and exited containers   There are two ways to run the image in the container     docker run  OPTIONS  IMAGE  TAG  DIGEST   COMMAND   ARG       In detached mode   -d false  Detached mode  Run container in the background  print new container id   In interactive mode   -i  Keep STDIN open even if not attached   Here is the Docker run command    docker run image name tag name   For more clarification on Docker run  you can visit Docker run reference   It s the best material to understand Docker
