Note: You may have been redirected to this page because there is no longera dynamically-linked Docker package for your Linux distribution.

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).

Verify Docker Installation Working with Docker Images. A Docker image is a read-only template file with instructions for creating a Docker container. You can either create your custom images or you can only use those created by others and published in the Docker Hub, the world’s largest library and community for container images. Docker is an application that makes it simple and easy to run application processes in a container, which are like virtual machines, only more portable, more resource-friendly, and more dependent on the host operating system.

This topic discusses binary installation for both Linux and macOS:

Install daemon and client binaries on Linux

Prerequisites

InstallGit

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
Git

Enable SELinux or AppArmor if possible.

It is recommended to use AppArmor or SELinux if your Linux distribution supportseither of the two. Update mac to latest version. 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.

Git
  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.

Next steps

  • Continue to Post-installation steps for Linux.
  • Take a look at the Get started training modules to learn how to build an image and run it as a containerized application.
  • Review the topics in Develop with Docker to learn how to build new applications using Docker.
