To launch Docker in Ec2 Instance and installing Webserver on Docker

To Launch An Instance in AWS ::

Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) Cloud. Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster. You can use Amazon EC2 to launch as many or as few virtual servers as you need, configure security and networking, and manage storage. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, reducing your need to forecast traffic.

▪ give name to your instance

▪ select instance type

▪ Download the key pair

▪Do network settings

▪Do network settings

▪ configure storage

▪ select no.of instances to launch

▪ If you want read the summary for review

Then click on LAUNCH INSTANCE

To connect to the launched instance using SSH

First we need to give permission using chmod command

$ chmod 400 redhat-key.pem

Then using ssh connect to the instance

$ ssh -i "key_name" <user_name>@ <public_ip>

To Install Docker In EC-2 Instance

Docker makes development efficient and predictable,Docker takes away repetitive, mundane configuration tasks and is used throughout the development lifecycle for fast, easy and portable application development.

$ apt-get install docker.io

Docker needs root permission ,we can't directly run docker by using normal user privilages

Before going to install docker,first you need to update the instance by running the command

$ apt-get update

Then run again the command to install the docker,then docker will be installed in your instance,To check use the command $ docker images

To launch a container using Docker

$ docker run -it <image_name>:<tag>(optional)

We can use run cmd or pull cmd to download os image in docker

When we run the command . it by default after installing the image it uses that image and we enter into that container

Here we need to use -p option for port forwarding

To install Web Server in Container

$ apt install apache2

Run the above command To install web server in ubuntu.
