In Ubuntu Server

----------------------

Method-1
=======

Step 1: Update all Software Repositories using below command.

#sudo apt-get update

Step 2: Install a Docker using below command

#sudo apt install docker.io -y

Step 3: Enable and start the docker service as follows.

#sudo systemctl enable docker
#sudo systemctl start docker

Step 4: Check the  docker version

#docker --version

# You will get permison denied error as regular user dosn't have permisions to execute docker commands, add ubuntu user to docker group.

#sudo usermod -aG docker $USER
     or 

#sudo usermod -aG docker ubuntu

# Exit From Current SSH Terminal & SSH(Login) again .Then execute
docker ps

To Un Install a docker
-----------------------------
Use below command to un-install docker
#apt-get remove docker docker-engine docker.io -y
----------------------------------------------------------------------------------------------------------------------------
Method -2
========
Step 1: Update all Software Repositories using below command.
#apt-get update


Step 2: Install Docker using below command
#curl -fsSL get.docker.com | /bin/bash


Step 3: Check all the versions.
#apt-cache madison docker-ce


Step 4: If we want to install the specific version use the below command.
apt-get install docker-ce=<VERSION>

Step 5: If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

#usermod -aG docker  <<YourUser>>
============================================================================

 In Amazon Linux
-----------------------
sudo yum update -y       
sudo yum install docker -y
sudo service docker start

Add Regural user to dockergroup
sudo usermod -aG docker  <username>

ex:
sudo usermod -aG docker ec2-user

Once you add user to group exit from the server and login again.
# Get docker information
docker info

#Install Docker in Linux (Works for most of linux flavors).
sudo curl -fsSL get.docker.com | /bin/bash

Docker Home Directory/Working Dir:
/var/lib/docker

============================================================================

Install Docker on AWS RHEL  (Offcially No Support)
----------------------------------------------------------------------
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo dnf install docker-ce-3:18.09.1-3.el7 -y
sudo systemctl enable docker
sudo systemctl start docker

sudo docker info

# Check docker is installed or not
docker info

# You will get permison denied error as regular user dosn't have permisions to execute docker commands, add user to docker group.

sudo usermod -aG docker $USER
or
sudo usermod -aG docker ec2-user

# Exit From Current SSH Terminal & SSH(Login) again .Then execute
docker ps
