Running [Drone](https://drone.io/) [Kubernetes Runner](https://docs.drone.io/installation/runners/kubernetes/) at local
## Requirements
* [kind](https://github.com/kubernetes-sigs/kind)
* kubectl
* [Ngrok](https://ngrok.com/): to receive webhooks from GitHub
* GitHub account: to create a GitHub OAuth app
* [Helm](https://helm.sh/): to install MySQL
* (optional) [kubectx](https://github.com/ahmetb/kubectx)
* (optoinal) [stern](https://github.com/wercker/stern)
## Note
Please be careful that temporarily we publish Drone with Ngrok.
We don't have any responsiblity.
We recommend to restrict users who can login Drone.
https://docs.drone.io/installation/security/registration/
Ngrok's URL is changed everytime `ngrok http`, so you have to reactivate repositories and remove old webhooks.
You can check the status of webhook and remove old webhooks from `https://github.com///settings/hooks` .
## Ngrok
Install Ngrok and create your account.
https://ngrok.com/
```
$ brew cask install ngrok
```
## Create a kubernetes cluster with kind
```
$ kind create cluster --name drone
$ kubectl create ns drone
$ kubens drone
```
## Watch logs with stern
It is useful for trouble shooting.
```
$ stern ".*"
```
## Install MySQL with Helm
https://github.com/helm/charts/tree/master/stable/mysql
```
$ bash scripts/install-mysql.sh
```
Connect MySQL.
```
$ kubectl exec -ti drone-mysql-??? mysql -- -u root -p drone
```
## Install Drone Server
* https://docs.drone.io/installation/providers/github/
### Create a GitHub OAuth App
Create a GitHub OAuth App from https://github.com/settings/applications/new
Homepage URL and Authorization callback URL are http://example.com . After we publish Drone with Ngrok, change these URLs.
### Create Kubernetes Secrets
* [DRONE_DATABASE_DATASOURDE](https://docs.drone.io/installation/reference/drone-database-datasource/)
```
$ echo -n '' > secrets/drone-github-client-id
$ echo -n '' > secrets/drone-github-client-secret
$ echo -n '' > secrets/drone-database-datasource
$ echo -n '' > secrets/drone-rpc-secret
```
```
$ kubectl create secret generic drone-server \
--from-file=secrets/drone-github-client-id \
--from-file=secrets/drone-github-client-secret \
--from-file=secrets/drone-database-datasource
$ kubectl create secret generic drone-server-rpc \
--from-file=secrets/drone-rpc-secret
```
### Install Drone Server
Don't forget to update [DRONE_USER_FILTER](https://docs.drone.io/installation/reference/drone-user-filter/) of server.yaml before `kubectl apply`.
About the parameters, please see https://docs.drone.io/installation/reference/ .
```
$ kubectl apply -f server.yaml
```
You can confirm that database is migrated.
```
mysql> show tables;

## Install Drone Runner
* https://kube-runner.docs.drone.io/installation/installation/
About the parameters, please see https://kube-runner.docs.drone.io/installation/reference/ .
```
$ kubectl apply -f runner.yaml
```
## Publish Drone with Ngrok
```
$ kubectl port-forward svc/drone-server 4000:4000
```
```
$ ngrok http 4000
```
We recommend to use the URL not http but https.
Update the GitHub OAuth App's Homepage URL and Callback URL, and server.yaml's `DRONE_SERVER_HOST`.
The path of Callback URL is `/login`.
```
$ kubectl apply -f server.yaml
```
Note that you have to do these operations everytime you run `ngrok http` because Ngrok's URL is changed.
Then access to Drone from your web browser.
## Create a sample repository to run CI with Drone
https://kube-runner.docs.drone.io/configuration/overview/
.drone.yaml
Don't forget `type: kubernetes`.
```yaml
---
kind: pipeline
type: kubernetes
name: default
steps:
- name: hello
image: alpine:3.10.3
commands:
- time 20
- echo hello
```
You can confirm that the pod is running while the pipeline is running.
```
$ kubectl get pod
```
