1. Clone this repository - https://github.com/diksha/HW4

   git clone https://github.com/diksha/HW4.git

2. Run docker-compose up

This will create containers for proxy main and redis and will also start the server.

3. Run infrastructure.js node infrastructure.js

4. Spawn a new server

localhost:8001/spawn

This will spawn a new server

##Part 2

1. Copy HW4Part2 post-commit into git hooks of App
2. Copy HW4Part2 green_post-receive to post-receive in green.git hooks
3. Copy HW4Part2 blue_post-receive to post-receive in blue.git hooks

Commit some change to App And then push to blue or green git push green master

We can see that the code is pushed to green and a docker is spawned.

##Part 3

1. Clone HW4Part3

Do the following steps

Create a container that runs a command that outputs to a file.

docker build -t container1 .

Use socat to map file access to read file container and expose over port 9001 (hint can use SYSTEM + cat).

docker run -td --name first_container container1

Creates 1st container

docker build -t container2 . docker run -td --link first_container1:input --name second_container1 container2

Creates 2nd container and links it

docker exec -it second_container1 bash

Use a linked container that access that file over network. The linked container can just use a command such as curl to access data from other container.

curl input:9001
