This tutorial explains, how to install docker on EC2 Instance. Before starting, let’s have some brief knowledge about Docker.

  1. Ubuntu Install Specific Docker Version
  2. Install Docker Version 19.03.12
  3. Install Docker Version 19.03.5
  4. Install Docker Version Download

Docker is a platform that combines applications and its dependencies in the form of packages, called container. We can run multiple containers on a single Operating System. Containers are not Virtual Machines. Virtual Machines requires Operating System to run applications, but containers do not. As containers don’t need an Operating System, it takes very little time to start and hence it is very faster than Virtual Machines.

Install Docker Testing Version Docker is an increasingly popular software package that creates a container for application development. Developing in Docker speeds up applications, as it shares the kernel and other resources, instead of requiring dedicated server resources. Let’s Install Docker on EC2 Instance. In this tutorial, we will use Amazon Linux to install docker. Amazon Linux/Amazon Linux2 is the Linux Operating System used in EC2 Instance. Step 1– Log to Linux EC2 Instance and update it. $ sudo yum update -y. Step 2– Install docker using Yum command $ sudo yum install docker -y.

  • Docker doesn’t need a graphical interface and it is best is to use the Raspbian Stretch Lite image and enable SSH. This way your Raspberry Pi will have much more available processing power and memory to run the Docker containers. Install Docker on Raspberry Pi # Installing Docker on Raspberry Pi is just a matter of running a few commands.
  • This example uses the script at get.docker.com to install the latest release of Docker Engine - Community on Linux. To install the latest testing version, use test.docker.com instead. In each of the commands below, replace each occurrence of get with test. Warning: Always examine scripts downloaded from the internet before running them locally.

and Launching Amazon Linux EC2 Instance

Let’s Install Docker on EC2 Instance

In this tutorial, we will use Amazon Linux to install docker. Amazon Linux/Amazon Linux2 is the Linux Operating System used in EC2 Instance.

Step 1– Log to Linux EC2 Instance and update it.

$ sudo yum update -y

Step 2– Install docker using Yum command

$ sudo yum install docker -y

Step 3– Start Docker Service

$ Service docker start

Step 4– Check docker Version.

$ docker -v

Basic Configuration (Creating Docker File / Running Docker Image)

After you install docker on ec2 , let’s have some basic setup for Docker.

Step 1 – Create a docker file

Dockerfile is a text file where we write instructions to build an image.

Create a folder name Images on the Amazon Linux box.

$ mkdir images

Move to folder images

$ cd images

Create a file name Dockerfile inside images folder

$ nano Dockerfile

Put the content in the following way inside the Dockerfile.

FROM Ubuntu ( It will use the Official image Ubuntu to build your image)

MAINTAINER chandan <[email protected]>

( It sets the Author field of the generated image)

RUN apt-get update ( It will update the image at the time of Build)

CMD [ “echo”, ” Hello World ……….! “] ( It will run echo command when we run the docker container image)

Step 2– Run the docker build command to build the image.

$ docker build .

Note : ( . command is used when you are inside images folder where Dockerfile is present, alternatively you can put the docker file absolute path like /home/ec2-user/images/Dockerfile)

You can run the following command as well to Name and tag your Image. Here myimage is the Name and 01 is Tag of the image.

$ docker build -t myimage:01 .

Step 3– See the Docker Images after build

$ docker images

Step 4 – Run the docker image

$ docker run 07deaa33585e

Here 07deaa33585e is the IMAGE ID that can be seen in docker images command.

You can see here, it executed the echo command as soon as we run the docker image. In the same way, we can run any script, commands or any application by running a docker image.

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 Install Specific Docker Version

  • 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

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

Version
  • 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

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. Descargar mac os x 10.1 puma iso. 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.

Install Docker Version 19.03.12

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:

Install Docker Version 19.03.5

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

Yum install docker version

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

Install Docker Version Download

  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.
