containerized my personal website and run it on AWS EC2 instance

In this lab, I launch EC2 instance on configured infrastructure (see Lab 2), install Docker on EC2, create a custom Docker container - copy over an existing application, install and launch web server, build and tag the Docker image, run application from Docker container on EC2 instance, push Docker container to Docker Hub.

To create custom EC2 instance on configured infrastructure, run:

python kbosko-lab3.py

While creating EC2 instance, the shell script Docker.sh is executed which installs Docker and Apache web server, creates Docker container, builds it and runs it.

Docker container runs my website www.cross-validated.com which is downloaded from S3 bucket created in previous Lab 2.

NOTE: you need to paste your own resources both in python and bash scripts.

There are several ways to debug if got stuck:

1. Attach shell to docker container

#check docker ID
docker ps
docker exec -it {container ID} bash

2. Check log file for EC2 instance through AWS management console

Right-click on EC2 instance --> Monitor and troubleshoot --> Get system log

3. Check log file for container after SSH into the instance from local machine

sudo less  /var/log/cloud-init-output.log

See documentation on how to Run commands on your Linux instance at launch

4. Check that UserData got attached to EC2 instance from AWS management console

Right-click on instance --> Instance Settings --> View/Change User Data

Pushing Docker container to repo in Docker Hub:

1. Create repository in Docker Hub
2. Docker login
3. Retag your Docker container

docker tag <existing-image> <hub-user>/<repo-name>[:<tag>]

or when building assign correct tags

docker build -t <hub-user>/<repo-name>[:<tag>]

4. Docker push

docker push <hub-user>/<repo-name>:<tag>
