# Terraform config for drone
[![Build Status](https://drone.thomasklein.me/api/badges/thomasklein/terraform-app-drone/status.svg)](https://drone.thomasklein.me/thomasklein/terraform-app-drone)

Drone is a self-hosted Continuous Integration platform. This terraform root module will create a Gitea OAuth2 application, a persistent volume for Drone and installs Drone to a Kubernetes namespace on Lawndale.

**This module assumes Lawndale as the hosting environment!**

## Provider configurations
The following providers are used and should be configured before calling `init` or `apply`.

### AWS
AWS is only used for state backend. Check out [AWS Provider config](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#authentication-and-configuration).

### Gitea
Either `GITEA_TOKEN` or `GITEA_USERNAME` and `GITEA_PASSWORD` must be set for authentication.

### Kubernetes / Helm
Drone is provisioned with Helm on a kubernetes cluster.

Helm is using the same environment variables as the Kubernetes provider.

Set `KUBE_CONFIG_PATH` to use a kubeconfig file, and `KUBE_CTX` to use a different context than set in the kubeconfig.

For token auth, set `KUBE_TOKEN` and `KUBE_HOST` environment vars. 

A PEM-encoded root certificates bundle for TLS authentication can be sourced by setting 
`KUBE_CLUSTER_CA_CERT_DATA`.

## Persistent volume
Persistence is supported by [terraform-modules//9p-persistent-volume](git.thomasklein.me/thomasklein/terraform-modules/9p-persistent-volume).
