Docker Machine Install Ubuntu

Posted on by



C: choco install docker-machine Using Git Bash terminal, use Docker Machine to install Docker Engine. This will download a Linux image containing the Docker Engine and have it run as a VM using. Install Docker CE: yum install docker-ce. Systemctl start docker systemctl enable docker Test Docker installation: docker run hello-world. Remove old versions of Docker: apt-get remove docker docker-engine docker.io. If you are installing on Ubuntu 14.04, install the linux-image-extra package.

Estimated reading time: 10 minutes

  1. Now you need docker cli, you can install Linux vm then install docker in that Linux vm you just installed. Then run which docker and copy this file to your windows computer. Copy the docker executable into /usr/local/bin on your WSL.
  2. Sudo apt-get install docker-ce=5:19.03.103-0ubuntu-focal docker-ce-cli=5:19.03.103-0ubuntu-focal containerd.io If you just want to latest version without specifying above, run the commands below. The command below will always install the highest possible version.

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)

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

Machine

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.

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 Post-installation steps for Linux to allownon-privileged users to run Docker commands and for other optional configurationsteps.

Upgrade Docker Engine

20.04

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: Mac os catalina windows bootcamp.

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:

You must delete any edited configuration files manually.

Next steps

  • Continue to Post-installation steps for Linux.
  • Review the topics in Develop with Docker to learn how to build new applications using Docker.

Setting up SMTP Email (Recommended)¶

The default single-container Docker instance for Mattermost is designedfor product evaluation, and sets SendEmailNotifications=false so theproduct can function without enabling email. To see the product’s fullfunctionality, enabling SMTP email is recommended.

To enable email, configure an SMTP email service as follows:

  1. Set up an SMTP email sending service (if you don’t yet have anSMTP service with credentials)

    • Any SMTP email service can be used, you just need the following

      information: ServerName, Port, SMTPUsername, andSMTPPassword.

      • If you don’t have an SMTP service, here are simple instructions

        to set one up with Amazon Simple Email Service(SES):

        1. Go to Amazon SESconsole thenSMTPSettings>CreateMySMTPCredentials

        2. Copy the ServerName, Port, SMTPUsername, andSMTPPassword for Step 2 below.

        3. From the Domains menu set up and verify a new domain,then enable GenerateDKIMSettings for the domain.

          1. We recommend you set up Sender PolicyFramework(SPF) and/or Domain Keys IdentifiedMail(DKIM) for your email domain.

        4. Choose a sender address like mattermost@example.com andclick SendaTestEmail to verify setup is workingcorrectly.

  2. Configure SMTP settings

    1. Open the System Console by logging into an existing team andaccessing “System Console” from the main menu.

      • Alternatively, if a team doesn’t yet exist, go to

        http://dockerhost:8065/ in your browser, create a team,then from the main menu click System Console

    2. Go to the Authentication > Email tab and configure the following:

      1. Allow Sign Up With Email:true

    3. Go to the Notifications > Email tab and configure the following:

      1. Send Email Notifications:true

      2. Notification Display Name: Display name on email accountsending notifications

      3. Notification Email Address: Email address displayed onemail account used to send notifications

      4. SMTP Username: SMTPUsername from Step 1

      5. SMTP Password: SMTPPassword from Step 1

      6. SMTP Server: SMTPServer from Step 1

      7. SMTP Port: SMTPPort from Step 1

      8. Connection Security: TLS(Recommended)

      9. Then click Save

      10. Then click Test Connection

      11. If the test failed please look in OTHER > Logs for anyerrors that look like [EROR]/api/v4/email/test..

    4. (Optional) Go to the Security > Sign Up tab and configure the following:

      1. Enable Email Invitations:true

Troubleshooting SMTP¶

Install Docker Machine On Ubuntu

TLS/STARTTLS Requirements¶

If you fill in SMTP Username and SMTP Password then you must setConnection Security to TLS or to STARTTLS

Troubleshooting using Logs¶

If you have issues with your SMTP install, from your Mattermost teamsite go to the main menu and open System Console -> Logs to look forerror messages related to your setup. You can do a search for the errorcode to narrow down the issue. Sometimes ISPs require nuanced setups forSMTP and error codes can hint at how to make the proper adjustments.

Docker Machine Install Ubuntu 16.04

For example, if System Console -> Logs has an error code reading:

Search for 5545.7.1error andClienthostrejected:Accessdenied.

Checking your SMTP server is reachable¶

  • Attempt to telnet to the email service to make sure the server isreachable.

  • You must run the following commands from the same machine or virtualinstance where mattermost/bin/mattermost is located.

  • Telnet to the email server with telnetmail.example.com25. Ifthe command works you should see something like

  • Then type something like HELO<yourmailserverdomain>. If thecommand works you should see something like

Note

As we’re not installing telnet by default on the official docker images you either need to use ping on those or install telnet yourself either directly or by modifying the Dockerfile.
