Introduction to EC2 Virtual Cloud Server

• A virtual server in AWS Cloud, providing computing capacity

Steps to deploy a web application on EC2 instance

• Create an EC2 instance on AWS

• Connect to EC2 instance with ssh

• Install Docker on remote EC2 instance

• Run Docker container (docker login, pull, run) from private repository

• Configure EC2 Firewall to access application externally from the browser

1 Steps to launch EC2 instance

1. Choose OS Image

2. Choose capacity

3. Network configurations

4. Add storage

5. Add tags

6. Configure Security Group

2 Connect to EC2 server via ssh using downloaded private ssh key

go to Services EC2 then launch instance button

add tags = why you create this instance or you can say that what is that

who can access this insances

You must downlad key pair because you will not be able to download file again after it is created

Connect to EC2 Instance

• you can add pem file in ./ssh file

• mv Downloads/docker-server.pem ~/.ssh/

• then you can give permission to pem file

• chmod 400 .ssh/docker-server.pem

• then you can connect with ssh and ec2-user this is a user of the aws account

• ssh -i ~/.ssh/docker-server.pem ec2-user@aws public ip

Install Docker on EC2

• first you must yum update= update your package manager tool

• sudo yum update

• sudo yum install docker

• docker --version

• then you have to start docker services

• sudo service docker start

• ps aux | grep docker

• if you dont want to write sudo command you can do that then you must exit and start

• sudo usermod -aG docker $USER

• groups

• docker run redis

RUN WEBAPPLICATION ON EC2

Pull docker image

Run Docker container

GitHub - nanuchi/react-nodejs-example: Example Project demonstrating how to develop React application with NodejsGitHub

app starts at port 3080 inside the docker container

in the aws account you can do that

• docker login

• docker pull nanajanashia/demo-app:1.0

• docker images

• you must run docker images

• bind to port 3000 on EC2 Server

• docker run -d -p 3000:3080 nanajanashia/demo-app:1.0 = you create container for iamges

• docker ps

• but your aws account doesnt open 3000 port you have to open this port
