# Deployment

To deploy:

```
kubectl apply -n drone -f application.yml
```

To bootstrap secrets:

```
 kubectl create secret generic -n drone application-secrets \
    --from-literal=DRONE_GITEA_CLIENT_ID=... \
    --from-literal=DRONE_GITEA_CLIENT_SECRET=... \
    --from-literal=DRONE_RPC_SECRET=$(cat /dev/urandom | base64 | head -c 30)
```

# Integrating with Docker registry

We use harbor.k-space.ee to host own images.

Set up robot account `robot$k-space+drone` in Harbor first.

In Drone associate `docker_username` and `docker_password` secrets with the
`k-space`.

Instead of click marathon you can also pull the CLI configuration for Drone
from https://drone.k-space.ee/account

```
drone orgsecret add k-space docker_username 'robot$k-space+drone'
 drone orgsecret add k-space docker_password '...'
```

# Integrating with e-mail

To (re)set e-mail credentials:

```
drone orgsecret add k-space email_password '...'
```

To issue build hit the button in Drone web interface or alternatively:

```
drone build create k-space/...
```

# Using templates

Templates unfortunately aren't pulled in from this Git repo.

Current `docker.yaml` template includes following:
