Digitalocean Terraform Tutorial

1. Clone this repo
2. Install terraform
3. Install doctl
4. Run terraform init in this repo. This will initialize Terraform and get us ready to run Terraform plans.
5. Run doctl auth init to login to DigitalOcean. This will get us ready to pull data from DigitalOcean.
6. Get an API token from your DigitalOcean account from https://cloud.digitalocean.com/account/api/tokens
7. Set it to DIGITALOCEAN_TOKEN in your terminal environment with export DIGITALOCEAN_TOKEN=<your token>. This will be used by Terraform.
8. Run terraform plan -out plan.tfplan to plan this Terraform application.
9. Run terraform apply "plan.tfplan" to apply this to your DigitalOcean account. This will launch a K8s cluster, a Postgres DB, and a Redis DB. This can take a long time to run. Note the Postgres and Redis databases are just for show, nothing is setup to use them.
10. Run doctl kubernetes cluster kubeconfig save dcsil-cluster to download the kubernetes config for the cluster we just launched (named dcsil-cluster).
11. Run ./launch.sh to launch nginx/load balancers on your Kubernetes Cluster. This script will set up a DCSIL namespace, then launch our nginx application on Kubernetes. Next it will launch a LoadBalancer that is set up to serve data from any apps with the label "nginx". This script can take a while to run.
12. Go to the IP Address the script prints out. This should show the nginx page.
