Install using the convenience script. Docker provides a convenience script at get.docker.com to install Docker into development environments quickly and non-interactively. The convenience script is not recommended for production environments, but can be used as an example to create a provisioning script that is tailored to your needs. Install command completion Bash. Make sure bash completion is installed. On a current Linux OS (in a non-minimal installation), bash completion should be available. Place the completion script in /etc/bashcompletion.d/.

Docker Script Installer

You can install Harbor in different configurations:

The script does not provide options to specify which version of Docker to install,and installs the latest version that is released in the “edge” channel. Do not use the convenience script if Docker has already been installed on thehost machine using another mechanism.

  • Just Harbor, without Notary, Clair, or Chart Repository Service
  • Harbor with Notary
  • Harbor with Clair
  • Harbor with Chart Repository Service
  • Harbor with two or all three of Notary, Clair, and Chart Repository Service

Default installation without Notary, Clair, or Chart Repository Service

The default Harbor installation does not include Notary or Clair service. Run the following command

If the installation succeeds, you can open a browser to visit the Harbor interface at http://reg.yourdomain.com, changing reg.yourdomain.com to the hostname that you configured in harbor.yml. If you did not change them in harbor.yml, the default administrator username and password are admin and Harbor12345.

Log in to the admin portal and create a new project, for example, myproject. You can then use Docker commands to log in to Harbor, tag images, and push them to Harbor.

  • If your installation of Harbor uses HTTPS, you must provide the Harbor certificates to the Docker client. For information, see Configure HTTPS Access to Harbor.
  • If your installation of Harbor uses HTTP, you must add the option --insecure-registry to your client’s Docker daemon and restart the Docker service. For more information, see Connecting to Harbor via HTTP below.

Installation with Notary

To install Harbor with the Notary service, add the --with-notary parameter when you run install.sh:

For installation with Notary, you must configure Harbor to use HTTPS.

For more information about Notary and Docker Content Trust, see Content Trust in the Docker documentation.

Installation with Clair

To install Harbor with Clair service, add the --with-clair parameter when you run install.sh:

For more information about Clair, see the Clair documentation.

By default, Harbor limits the CPU usage of the Clair container to 150000 to avoid it using up all CPU resources. This is defined in the docker-compose.clair.yml file. You can modify this file based on your hardware configuration.

Installation with Chart Repository Service

To install Harbor with chart repository service, add the --with-chartmuseum parameter when you run install.sh:

Installation with Notary, Clair, and Chart Repository Service

If you want to install all three of Notary, Clair and chart repository service, specify all of the parameters in the same command:

Connecting to Harbor via HTTP

IMPORTANT: If your installation of Harbor uses HTTP rather than HTTPS, you must add the option --insecure-registry to your client’s Docker daemon. By default, the daemon file is located at /etc/docker/daemon.json.

For example, add the following to your daemon.json file:

After you update daemon.json, you must restart both Docker Engine and Harbor.

  1. Restart Docker Engine.

  2. Stop Harbor.

  3. Restart Harbor.

How can I install Docker CE on Ubuntu 20.04 19.04 18.04 16.04 Linux distribution. Docker Engine is a container runtime engine which allows you to package your applications with all of its dependencies into a standardized unit for software development and distribution.

Docker Script Install

To get started with Docker Engine on Ubuntu, make sure youmeet the prerequisites, theninstall Docker.

Prerequisites

OS requirements

To install Docker Engine, you need the 64-bit version of one of these Ubuntuversions:

  • Ubuntu Groovy 20.10
  • Ubuntu Focal 20.04 (LTS)
  • Ubuntu Bionic 18.04 (LTS)
  • Ubuntu Xenial 16.04 (LTS)
  1. Installing Docker on Ubuntu 20.04. To use the latest version of Docker, we will install it from the official Docker repository. So, start by adding the GPG key for the official Docker repository to your system, after that add the repository configuration to the APT source with the following commands.

  3. In order to install Prometheus on Docker, you will need to have sudo rights on your host. If you are not sure about it, run the following command $ sudo -v 1. Installing Docker on Ubuntu. Before installing Prometheus on Docker, it is important that Docker is already correctly installed and configured on your instance.
  4. Docker is a software package that creates containers for application development. Learn how to Install Docker on Ubuntu 18.04 in this tutorial.

Docker Engine is supported on x86_64 (or amd64), armhf, and arm64 architectures.

Uninstall old versions

Older versions of Docker were called docker, docker.io, or docker-engine.If these are installed, uninstall them:

It’s OK if apt-get reports that none of these packages are installed.

The contents of /var/lib/docker/, including images, containers, volumes, andnetworks, are preserved. If you do not need to save your existing data, and want tostart with a clean installation, refer to the uninstall Docker Enginesection at the bottom of this page.

Supported storage drivers

Docker Engine on Ubuntu supports overlay2, aufs and btrfs storage drivers.

Docker Engine uses the overlay2 storage driver by default. If you need to useaufs instead, you need to configure it manually.See use the AUFS storage driver

Installation methods

You can install Docker Engine in different ways, depending on your needs:

  • Most usersset up Docker’s repositories and installfrom them, for ease of installation and upgrade tasks. This is therecommended approach.

  • Some users download the DEB package andinstall it manually and manageupgrades completely manually. This is useful in situations such as installingDocker on air-gapped systems with no access to the internet.

  • In testing and development environments, some users choose to use automatedconvenience scripts to install Docker.

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you needto set up the Docker repository. Afterward, you can install and update Dockerfrom the repository.

Set up the repository

  1. Update the apt package index and install packages to allow apt to use arepository over HTTPS:

  2. Add Docker’s official GPG key:

  3. Use the following command to set up the stable repository. To add thenightly or test repository, add the word nightly or test (or both)after the word stable in the commands below. Learn about nightly and test channels.

    Note: The lsb_release -cs sub-command below returns the name of yourUbuntu distribution, such as xenial. Sometimes, in a distributionlike Linux Mint, you might need to change $(lsb_release -cs)to your parent Ubuntu distribution. For example, if you are using Linux Mint Tessa, you could use bionic. Docker does not offer any guarantees on untestedand unsupported Ubuntu distributions.

Install Docker Engine

  1. Update the apt package index, and install the latest version of DockerEngine and containerd, or go to the next step to install a specific version:

    Got multiple Docker repositories?

    If you have multiple Docker repositories enabled, installingor updating without specifying a version in the apt-get install orapt-get update command always installs the highest possible version,which may not be appropriate for your stability needs.

  2. To install a specific version of Docker Engine, list the available versionsin the repo, then select and install:

    a. List the versions available in your repo:

    b. Install a specific version using the version string from the second column, for example, 5:18.09.1~3-0~ubuntu-xenial.

  3. Verify that Docker Engine 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.

Docker Engine is installed and running. The docker group is created but no usersare added to it. You need to use sudo to run Docker commands.Continue to Linux postinstall to allow non-privilegedusers to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine

To upgrade Docker Engine, first run sudo apt-get update, then follow theinstallation instructions, choosing the newversion you want to install.

Install from a package

If you cannot use Docker’s repository to install Docker Engine, you can download the.deb file for your release and install it manually. You need to downloada new file each time you want to upgrade Docker.

  1. Go to https://download.docker.com/linux/ubuntu/dists/,choose your Ubuntu version, then browse to pool/stable/, choose amd64,armhf, or arm64, and download the .deb file for the Docker Engineversion you want to install.

    Note: To install a nightly or test (pre-release) package,change the word stable in the above URL to nightly or test.Learn about nightly and test channels.

  2. Install Docker Engine, changing the path below to the path where you downloadedthe Docker package.

    The Docker daemon starts automatically.

  3. Verify that Docker Engine 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.

Upgrade Docker Engine

To upgrade Docker Engine, download the newer package file and repeat theinstallation procedure, pointing to the new file.

Install using the convenience script

Docker provides convenience scripts at get.docker.comand test.docker.com for installing edge andtesting versions of Docker Engine - Community into development environments quickly andnon-interactively. The source code for the scripts is in thedocker-install repository.Using these scripts is not recommended for productionenvironments, and you should understand the potential risks before you usethem:

  • The scripts require root or sudo privileges to run. Therefore,you should carefully examine and audit the scripts before running them.
  • The scripts attempt to detect your Linux distribution and version andconfigure your package management system for you. In addition, the scripts donot allow you to customize any installation parameters. This may lead to anunsupported configuration, either from Docker’s point of view or from your ownorganization’s guidelines and standards.
  • The scripts install all dependencies and recommendations of the packagemanager without asking for confirmation. This may install a large number ofpackages, depending on the current configuration of your host machine.
  • The script does not provide options to specify which version of Docker to install,and installs the latest version that is released in the “edge” channel.
  • Do not use the convenience script if Docker has already been installed on thehost machine using another mechanism.

This example uses the script at get.docker.com toinstall the latest release of Docker Engine - Community on Linux. To install the latesttesting version, use test.docker.com instead. Ineach of the commands below, replace each occurrence of get with test.

Warning:

Always examine scripts downloaded from the internet beforerunning them locally.

If you would like to use Docker as a non-root user, you should now consideradding your user to the “docker” group with something like:

Remember to log out and back in for this to take effect!

Warning:

Adding a user to the “docker” group grants them the ability to run containerswhich can be used to obtain root privileges on the Docker host. Refer toDocker Daemon Attack Surfacefor more information.

Docker Engine - Community is installed. It starts automatically on DEB-based distributions. OnRPM-based distributions, you need to start it manually using the appropriatesystemctl or service command. As the message indicates, non-root users can’trun Docker commands by default.

Note:

To install Docker without root privileges, seeRun the Docker daemon as a non-root user (Rootless mode).

Upgrade Docker after using the convenience script

If you installed Docker using the convenience script, you should upgrade Dockerusing your package manager directly. There is no advantage to re-running theconvenience script, and it can cause issues if it attempts to re-addrepositories which have already been added to the host machine.

Uninstall Docker Engine

  1. Uninstall the Docker Engine, CLI, and Containerd packages:

  2. Images, containers, volumes, or customized configuration files on your hostare not automatically removed. To delete all images, containers, andvolumes:

Ubuntu

You must delete any edited configuration files manually.
