Install Docker Container

Estimated reading time: 5 minutes

Docker is a platform for running applications in an isolated environment called a 'container' (or Docker container). Applications like Jenkins can be downloaded as read-only 'images' (or Docker images), each of which is run in Docker as a container. A Docker container is in effect a 'running instance' of a Docker image.

In order to create and run a Docker container, first you need to run a command into a downloaded CentOS image, so a basic command would be to check the distribution version file inside the container using cat command, as shown. $ docker run centos cat /etc/issue 14. Docker icon + message when starting Docker desktop. Container: A container is the running instance of the image, so we can have multiple containers running based on the same image. So, let's start by opening the command prompt and make sure the Docker desktop is running ( it can be verified by the icon on your system tray).

Docker is an application that simplifies the process of managing application processes in containers. In this tutorial, you'll install and use Docker Community Edition (CE) on Ubuntu 18.04.

Install Mysql In Docker Container

If you want to try Docker or use it in a testing environment, but you’re not ona supported platform, you can try installing from static binaries. If possible,you should use packages built for your operating system, and use your operatingsystem’s package management system to manage Docker installation and upgrades.Be aware that 32-bit static binary archives do not include the Docker daemon.

Static binaries for the Docker daemon binary are only available for Linux (asdockerd). Static binaries for the Docker client are available for Linux and macOS (as docker).

This topic discusses binary installation for both Linux and macOS:

Install daemon and client binaries on Linux

Prerequisites

Before attempting to install Docker from binaries, be sure your host machinemeets the prerequisites:

  • A 64-bit installation
  • Version 3.10 or higher of the Linux kernel. The latest version of the kernelavailable for your platform is recommended.
  • iptables version 1.4 or higher
  • git version 1.7 or higher
  • A ps executable, usually provided by procps or a similar package.
  • XZ Utils 4.9 or higher
  • A properly mountedcgroupfs hierarchy; a single, all-encompassing cgroup mountpoint is not sufficient. See Github issues#2683,#3485,#4568).

Secure your environment as much as possible

OS considerations

Enable SELinux or AppArmor if possible.

It is recommended to use AppArmor or SELinux if your Linux distribution supportseither of the two. This helps improve security and blocks certaintypes of exploits. Review the documentation for your Linux distribution forinstructions for enabling and configuring AppArmor or SELinux.

Security Warning

If either of the security mechanisms is enabled, do not disable it as awork-around to make Docker or its containers run. Instead, configure itcorrectly to fix any problems.

Docker daemon considerations
  • Enable seccomp security profiles if possible. SeeEnabling seccomp for Docker.

  • Enable user namespaces if possible. See theDaemon user namespace options.

Install static binaries

  1. Download the static binary archive. Go tohttps://download.docker.com/linux/static/stable/(or change stable to nightly or test),choose your hardware platform, and download the .tgz file relating to theversion of Docker Engine you want to install.

  2. Extract the archive using the tar utility. The dockerd and dockerbinaries are extracted.

  3. Optional: Move the binaries to a directory on your executable path, suchas /usr/bin/. If you skip this step, you must provide the path to theexecutable when you invoke docker or dockerd commands.

  4. Start the Docker daemon:

    If you need to start the daemon with additional options, modify the abovecommand accordingly or create and edit the file /etc/docker/daemon.jsonto add the custom configuration options.

  5. Verify that Docker is installed correctly by running the hello-worldimage.

    This command downloads a test image and runs it in a container. When thecontainer runs, it prints an informational message and exits.

Install client binaries on macOS

The macOS binary includes the Docker client only. It does not include thedockerd daemon.

  1. Download the static binary archive. Go tohttps://download.docker.com/mac/static/stable/x86_64/,(or change stable to nightly or test),and download the .tgz file relating to the version of Docker Engine you wantto install.

  2. Extract the archive using the tar utility. The docker binary isextracted.

  3. Optional: Move the binary to a directory on your executable path, suchas /usr/local/bin/. If you skip this step, you must provide the path to theexecutable when you invoke docker or dockerd commands.

  4. Verify that Docker is installed correctly by running the hello-worldimage. The value of <hostname> is a hostname or IP address running theDocker daemon and accessible to the client.

    This command downloads a test image and runs it in a container. When thecontainer runs, it prints an informational message and exits.

Upgrade static binaries

To upgrade your manual installation of Docker Engine, first stop anydockerd or dockerd.exe processes running locally, then follow theregular installation steps to install the new version on top of the existingversion.

After you have installed docker on your linux machine, the next step is to create an image and run a container. You need to create a base image of an OS distribution and after that you can add and modify the base image by installing packages and dependencies and committing the changes to it.

In this article, we will show you how to create an ubuntu base image and on top of that create intermediate image layers by adding packages in it and keep committing the changes. We will update the ubuntu base image, install 3 packages - vim editor, firefox and python 3.

Note that we can do this using two ways - either we mention all the commands inside a dockerfile and build the image all at once or we can do it step by step and keep committing the changes through CLI. We will discuss both the methods here.

Method 1. Step by Step using CLI.

  • Open a terminal and run the following command. Note that if you are not the root user, you need to add sudo before all the commands.

Install Vi Inside Docker Container

This will check if an ubuntu image exists locally or not. If it does not exist, it will display “Unable to find image 'ubuntu:latest' locally” message and start pulling it from docker hub. After pulling the image, it will run the apt update command.

  • We will now install a vim editor inside the container. For that, we will run the bash of the ubuntu image.

This will open an interactive ubuntu bash. Inside the bash, type the following commands one by one to install the packages.

The first command runs an update. It then installs vim editor, firefox and some dependencies for python 3. Then it adds the official python 3 repository and installs python 3.7 and then exits the bash.

You can check the version of python using the following command.

  • After exiting the bash, you need to commit the changes. Find out the container ID using the following command.

Install Docker Container Windows 10

Copy the container ID and paste in the following command.

  • You can check that the new ubuntu image with the specified name and installed packages has been created using the following command.

Method 2. By creating a dockerfile

  • Create a file name dockerfile and place the following commands in it.

Install docker container windows 10
  • Build the image using the following command.

This command builds the docker image using the dockerfile.

Run the docker image using the following command.

To conclude, the better method to create an image and install packages is by creating a dockerfile with the appropriate commands because it will help you to keep track of the changes that you make and the packages that you install and gives a better clarity of the whole project.
