Install Docker On Ec2

  1. I won't explain how to create a new EC2 instance. Install Docker // update sudo yum update -y // install most recent package sudo amazon-linux-extras install docker // start the service docker sudo service docker start // add the ec2-docker user to the group sudo usermod -a -G docker ec2-user // you need to logout to take affect logout // login again ssh -i '.pem' [email protected]
  2. $ docker info Install Docker on EC2 (via EC2 User data) If you do not want to manually configure it, the easiest option is passing the script via User data while creating the EC2 machine.

Sudo yum install docker. ## Check docker version. Docker -version. ## Add the ec2-user to the docker group so you can execute Docker commands without using sudo. ## Exit the terminal and re-login to make the change effective. Sudo usermod -a -G docker ec2-user. Install Docker Engine on Amazon Linux 2 EC2 Next, unlike other Linux systems, we don’t need to add an official docker repository on AWS Ec2 Linux manually to get the latest version. It is already there, we just need to run a single command using the YUM packages manager to install Docker’s community edition.

Ensure you are running Linux (kernel 3.8 or later) and have Docker(version 1.10.0 or later) installed.

Install Weave Net by running the following:

Install Weave Net by running the following: sudo curl -L git.io/weave -o /usr/local/bin/weave sudo chmod a+x /usr/local/bin/weave If you are on OSX and you are using Docker Machine ensure that a VM is running and configured before downloading Weave Net. We had this today with a fresh CoreOS 522.5.0 cluster (Docker 1.3.3 build 54d900a) on Amazon’s EC2. I am very unsure where the actual problem was. However it went away by reinstalling the cluster using the latest 522.6.0 AMIs.

If you are on OSX and you are using Docker Machine ensure that a VM is running and configured before downloading Weave Net. To set up a VM see the Docker Machinedocumentation or refer to “Part 1: Launching Weave Net with Docker Machine”.

After your VM is setup with Docker Machine, Weave Net can be launched directly from the OSX host. Weave Net respects the environment variable DOCKER_HOST, so that you can run and control a Weave Network locally on a remote host. See Using The Weave Docker API Proxy.

With Weave Net downloaded onto your VMs or hosts, you are ready to launch a Weave network and deploy apps onto it. See Launching Weave Net.

Quick Start Screencast

Checkpoint

Docker Install On Ec2

Weave Net periodically contacts Weaveworks servers for availableversions. New versionsare announced in the log and in the statussummary.

The information sent in this check is:

  • Host UUID hash
  • Kernel version
  • Docker version
  • Weave Net version
  • Network mode, e.g. ‘awsvpc’

To disable this check, run the following before launching Weave Net:

Guides for Specific Platforms

Amazon ECS users see herefor the latest Weave AMIs.

If you’re on Amazon EC2, the standard installation instructions at thetop of this page, provide the simplest setup and the most flexibility.A special no-overlay mode for EC2 canoptionally be enabled, which allows containers to communicate at thefull speed of the underlying network.

In this article we will perform Docker installation as well as we will configure “Container” and “Images” with easy steps on AWS Ec2 instance. We are using Amazon Linux distribution and assuming that you have already created your AWS account if not you can refer this article Create AWS free tier account. Once you logged into AWS account and connected to your AWS Ec2 instance you can follow below steps to perform Docker installations.

1.Get ready your Ec2 Instance

When you are logged into your AWS Ec2 instance you have to update all the packages, before that you have to switch to root user account using command sudo su and then you can use below command;

2. Install Docker

Once you used above command it will update packages on ec2 instance or it will give message “no packages marked for update” it means your ec2 instance already have all the latest packages installed.

Now, you can install Docker using below command,

This command will installed Docker softwares and its dependencies.

3.Verify Docker Installation

OR

4.Start Docker

Now, you can check status and start Docker service using below commands;

You can find all the status of the Docker using command “docker info” It will provide you all the information.

5.Check Available Docker Images/Containers

Now, you can check available Docker Images and Containers with help of below commands, if you don’t know about what is Docker Image, what is Docker Container, what is Docker Client and what is Docker Hub then you go through this Docker-Containers Lets understand it with simplest way article to easily understand all the terms.

“docker images” command used to check available images on your Docker server or Docker engine

“docker ps” (ps stand for process status) command is used to check all running containers and “docker ps -a” (-a stands for all) command is used to check all running as well as stopped containers.

6.Download Docker Images

Ec2

Now, you required to create and download Docker images of various distributions for that you can use docker file or you can directly download Docker images from hub.docker.com.

You can also download Docker images using below command,

Install docker on ec2 linux

Now, in below example I am installing “ubuntu” image. So, as you can see as soon as we run above command Docker search ubuntu image in local machine first and in case it not found Docker can pull image from hub.docker.com.

7.Verify Installed Images/Containers

As soon as you run above “docker run -it ubuntu /bin/bash” command your Docker container will be ready and you will be reached within that (ubuntu) Container. You can verify it using below command;

Now, you can enter exit command and you will be exit from the container and your container will also stopped. You can now use below command to check available images on your Docker server/engine.

This time you will see “ubuntu” image which we have installed.

Install Docker On Ec2 Ubuntu

Now, check available containers with below command;

You can find now, one Container available which is in stopped state.

8. Docker Commands Best Practices

Command to search docker images that available on docker hub

Command to start container; you can use container name or id to start container.

Command to go to inside the running containers; use container name or id to go inside running containers
