Master Of Puppets

This just demonstrate how you can provision and build sample go app in local environment.

• 3 ubuntu instances: 1 x Web(nginx) and 2 x App(GO)
• Using puppet to install and configure Nginx with round-robin and install app requirement on nodes.
• Using simple bash to build and run go app

Dependencies

Software dependencies.

• VirtualBox
• Vagrant

Running stack

For run and build web with 2x GO app just need to run:

make stack

So now you can check the stack from Nginx load-balancer from http://localhost:8000 (by refreshing the page app message should be changed). Also it possible to connect to nodes app-1: http://localhost:8001 app-2: http://localhost:8002

Destroy stack

Run this command to destroy stack

make destroy_stack

Running single node (web | app-1 | app-2)

If you need to run one of nodes and connect to vagrant machine via ssh you just need to run this command:

make machine ROLE=web
make machine ROLE=app-1
make machine ROLE=app-2

Destroy node

make destroy_machine ROLE=web
make destroy_machine ROLE=app-1
make destroy_machine ROLE=app-2

Travis-CI

You can see a build status on Travis-CI: https://travis-ci.org/ali-karimkhani/master_of_puppets. If the build will be success you should see the result of curl localhost:8080 something like this: Hi there, This is served from testing-worker-linux-docker-4f9c9dca-3389-linux-6!
