k8s consul/vault/transit-app/mariadb demo

Software requirements (on your laptop):

git curl jq kubectl(v1.17 or greater) helm3 consul vault

Setup

  1. Set your GCP creds. I've done mine via environment variables https://www.terraform.io/docs/providers/google/provider_reference.html

If using TFE, use the GOOGLE_CREDENTIALS environment variable. Also the JSON credential data is required to all be on one line. Just modify in a text editor before adding to TFE.

GOOGLE_CREDENTIALS: {"type": "service_account","project_id": "klaas","private_key_id":..........

  1. Fill out terraform.tfvars with your values

  2. plan/apply

terraform apply --auto-approve;
  1. Copy the command for "connecting" to your k8s cluster from the terraform output.
gcloud container clusters get-credentials your-cluster-name --zone us-central1-c --project your-project
  1. Deploy Consul/Vault/Mariadb/Python-transit-app. This takes a minute or two as there are a bunch of sleeps setup in the script.
cd demo
./full_stack_deploy.sh

cat that script if you want to see how to deploy each of the above by hand/manually.

Teardown

demo/cleanup.sh

UI

Refresh your browser tab when they initally open up. They are started by nohup commands using kubectl port-forward. see demo/vault/vault.sh and demo/consul/consul.sh
