deploy-dev-env

A simple terraform setup to deploy a dev environment to digital ocean.

The current setup allows the user to deploy a series of virtual machines to DigitalOcean. Currently it uses the sister repository here to generate the original template for use here.

What it generates:

• 3 vms:
  • 1 Loadbalancer vm that will eventually be loaded with something like HAProxy
  • 2 Application vms that will hold whatever dockerized applications you want.

Why?

• Basically there were situations in my life where I wanted to be able to build containerized applications and test them in front of a load balanced system.

How?

1. Complete the steps in the sister repository.
2. Move into the applications/backend folder

   cd applications/backend

3. Execute a terraform init:

   terraform init
   

4. Make sure you have your digital ocean api key set on an environmental variable:

   export do_token="TOKEN GOES HERE"
   

5. Manipulate the deployment variables as you see fit:

   vim env/dev.tfvars
   

6. Run a terraform apply (making sure to give it your tfvar file and you local env variable with your api key):

   terraform apply -var "do_token=${DO_PAT}" --var-file=/full/path/for/some/reason/required/env/dev.tfvars
   

7. Good to go to start testing the deployment out.

Whats Next:

• Integrate a load balancer on the load balancer machine
• I started a method for moving files over to the deployed machines using optional provisioning but opted to keep it out of the inital push and will focus on it later.
• Setup a local docker registry machine perhaps to make the pushing of containers easier? Not sure
