How to install Docker, run Docker containers on Linux Mint 1. Docker is an open source project supported by a commercial entity of the same name that makes it super easy to run an application process inside a relatively isolated environment called a container. Unlike a virtual machine VM, which has its own kernel, a container is dependent on the host operating systems kernel. As a result, its much lighter and boots up much faster. Its the simplest tool that puts enterprise class application deployment and management capabilities right on your desktop laptop. By default, Docker containers are run using application images hosted on Docker Hub. In this article, well go through the process of installing and using it to run containers on Linux Mint 1. Linux Mint 1. 8. 1 is set to be released very soon, but these instruction will work on it too. Enable Official Docker Repository on Linux Mint 1. The official repository of Linux Mint 1. Ubuntu 1. 6. 0. 4, contain a slightly outdated edition of the Docker package than is available on Ubuntu 1. Fedora 2. 5 see How to install Docker and run Docker containers on Fedora 2. For example, if you attempt to install it Docker from the official Linux Mint repository, you will likely be installing Docker 1. Docker 1. 1. 2. 3. KVM QEMU. So to make it such that the latest and greatest version of Docker will always be available on your system, its better to enable the official Docker repository. To get that done, run the following commands First import the GPG keysudo apt key adv keyserver hkp p. E8. 9F3. A9. 12. 89. C0. 70. ADBF7. 62. C5. 26. 09. D Next, point the package manager to the official Docker repositorysudo apt add repositorydeb https apt. Update the package databasesudo apt updateInstall Docker Prerequisites on Linux Mint 1. To install and successfully run Docker containers on Linux Mint 1. Installing both packages will eliminate an unmet dependencies error when you try to install the linux image extra virtual by itselfsudo apt install linux image generic linux image extra virtual Reboot the system so it would be running on the newly installed kernel imagesudo rebootInstall Docker on Linux Mint 1. Now that all is set, you may install Docker using the next command, which will not only install it, but also start the daemon and enable it, so that it will always start at boot. Install Dockersudo apt install docker engineRunManage Docker Containers on Linux Mint 1. The Docker daemon is up and running, so you may now run your first container using the following command Run a Docker container This container is just a test container, and it will run and exitsudo docker run hello worldAs stated earlier, images used to run Docker containers are, by default, hosted on Docker Hub. With hundreds, perhaps thousands of images available, how do you find an image with which to run a container By using Dockers search command. For example, lets see if Linux Mint has an image hosted on Docker Hub 1. How to search for Docker imagessudo docker searchlinux mint The output should be of this sort.

That indicates it came from the project itself, not from any random person. In the output above, for example, theres no official image for Linux Mint, but theres one for Ubuntu and Oracle Linux. So lets try and run a container using the official Ubuntu image Run a Docker container using the official Ubuntu imagesudo docker run it ubuntu bashThe above command will download the Ubuntu image, run the container, keep it running, and give you interactive tty access inside it, with the Bash shell. Youll notice that your command prompt has changed to something like root1. So your host machine is running Linux Mint 1. Ubuntu container. With command line access inside the container, you can do anything you want, like just exit the container, or do somethings more interesting, like update the package database, upgrade the system, and install any software you feel like installing. For now, you may exit the container by typing exit. In a future article, well go into details of how to install applications inside a container, commit the changes, and push the new image derived from that to Docker Hub. Lets end this by running another container using the official Nginx image. By default, running the Nginx container will expose its ports 8. What this command does is map port 8. Run a Docker container using the official Nginx imagesudo docker run p. Alternatively, you can force the container to detach by running this commandsudo docker run d p. Mapping the port in that fashion makes it possible to access the default Nginx page by pointing your browser to the host machines IP address. If you did that, you should see the default Nginx page, and if you ran the command without the d option, you should see some output indicating that the page has been accessed. Depending on the host machines resources, you can run as many containers as you want at the same time. Use the next set of commands to list the containers running on the host machine, stop a running container and remove a stopped container 1. List all containers, running or notsudo docker ps a The output of the above commands takes this form CONTAINER ID IMAGE COMMAND STATUS PORTS NAMES 2. Up 1. 4 seconds 6. Up 2 minutes 0. Exited 0 5 minutes ago infalliblelalande 0e. Exited 0 2 hours ago gravejones List only running containerssudo docker ps Remove a stopped container. Specify the containers id or name when removing it In this case, we remove the container using its namesudo docker rmgravejones To remove a running container, first stop it using its name or id In this case, we stop it using its idsudo docker stop. Then remove itsudo docker rm. Clean Up After Yourself. Whenever you run a container, the Docker client has to download an image from by default Docker Hub. The images are stored on your computer, and will remain there even after youve stopped and removed the container. With time, those images can take up a significant chunk of your computers storage space. So a good habit to adopt is to delete those images youll not be using anytime soon. To list the images stored on your computer, type Listing Docker imagessudo docker images Output of above command REPOSITORY TAG IMAGE ID CREATED SIZE redis latest 1c. MB ubuntu latest 4ca. MB nginx latest abf. MB hello world latest c. BDont think youll be needing an image anytime soon Delete it Delete a Docker image using its namesudo docker rmi hello world And in this case, using it idsudo docker rmi. Running individual Docker containers like you just read in this article is fun, but thats just the beginning. Docker has other features, like the Swarm Mode, which makes it easy to orchestrate a cluster of Docker containers across a cluster of servers running Docker.
