# Server configuration

## Goal
```bash
export SITE=tom.moulard.org
docker-compose up -d
```

Now you have my own server configuration

### Tear down
```bash
docker-compose down
```

    - [X] gitlab
    - [X] gitlab runner
    - [X] transmission
    - [ ] pastebin
    - [ ] nextcloud

## Configuration
Don't forget to change db passwords. (migth not be needed since they are beyond
the reverse proxy).
Fill vpn secrets(if none provided, they are generated directly).
Configuration files are: `docker-compose.yml`, `nginx.conf`

To set the password:
```bash
export HASHED_PASSWORD=$(openssl passwd -apr1)
```

### Scalling up
```bash
docker-compose scale nginx=2
```

### Gitlab runner
#### Get the Registration Token
Find your runner registration token ($REGISTRATION_TOKEN) at `http://GITLAB_HOST/$PROJECT_GROUP/$PROJECT_NAME/settings/ci_cd`.

There is **two** way to register the runner:

##### Register via config file
Register the Registration Token to have a Runner Token
```bash
curl -X POST 'http://gitlab.${SITE}/api/v4/runners' --form 'token=$REGISTRATION_TOKEN' --form 'description=The Best Runner'
```

###### Change runner configuration
Now change the token in the [configuration file](gitlab/runner/config.toml).
```toml
[[runners]]
    token = "XXXXXXXXXXXXXXXXXXXX"
```
and run the runner
```bash
docker-compose up -d runner
```

##### Register via CLI
Steps:
 - up the runner `docker-compose up -d runner`
 - register the runner
```bash
docker-compose exec runner gitlab-runner register \
    --non-interactive \
    --executor "docker" \
    --docker-image alpine:latest \
    --url "http://gitlab/" \
    --registration-token "$REGISTRATION_TOKEN" \
    --description "The Best Runner" \
    --tag-list "docker,aws" \
    --run-untagged="true" \
    --locked="false" \
    --access-level="not_protected"
```
