## Keycloak

#### How do I setup a custom theme?

Check [this approach](https://git.autonomic.zone/ruangrupa/login.lumbung.space).

#### How do I create another admin user?

- Under the `Master` realm > `Users` > `Add user`
- Create the user and set a temporary password
- Under the `Role Mappings` tab, move `admin` from `Available Roles` into `Assigned Roles`

## Nextcloud

#### How do I customise the default home page when logging in?

- Delete the dashboard app since it is so corporate
- Follow [these docs](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/default_files_configuration.html) to set the default files list for each user in the Files app
- Configure a `defaultapp` in your `config.php` or use [apporder](https://apps.nextcloud.com/apps/apporder)

#### How do I integrate with Keycloak SSO?

Use [this plugin](https://github.com/pulsejet/nextcloud-oidc-login). Unlike the plugin it's forked from, there is no configuration UI, so you'll need to edit `/var/www/html/config/config.php`:

```
  'oidc_login_client_id' => 'nextcloud',
  'oidc_login_client_secret' => 'mysecret',
  'oidc_login_provider_url' => 'https://example.com/auth/realms/myrealm',
  'oidc_login_disable_registration' => false,
  'oidc_login_hide_password_form' => true,
  'oidc_login_button_text' => 'Log in with your myssodomain',
  'oidc_login_default_group' => 'mygroup',
  'oidc_login_attributes' =>
  array (
    'id' => 'sub',
    'name' => 'name',
    'mail' => 'email',
  ),
  'oidc_create_groups' => true,
```

You can use [this trick](https://janikvonrotz.ch/2020/10/20/openid-connect-with-nextcloud-and-keycloak/) (see "Cryptic Usernames" work-around) to get proper usernames.

You might also need the following "Why is my synchronisation.." change if you see an error `'redirect_uri' is invalid`.

If you ever need to change the realm, you'll need to reset the cache with:

```
docker exec -u www-data <container-id> php occ config:app:delete oidc_login last_updated_well_known
docker exec -u www-data <container-id> php occ config:app:delete oidc_login last_updated_jwks
```

#### Why is my synchronisation client freezing on the "grant access" step?

Please see [this ticket](https://git.autonomic.zone/coop-cloud/nextcloud/issues/5).

#### How can I customise the CSS?

There is some basic stuff in the admin settings.

To go a little deeper, you can use [this handy app](https://apps.nextcloud.com/apps/theming_customcss).

Here is an example CSS config which hides the local login and makes space for a central image:

```css
#body-login .wrapper main form[name="login"],
#body-login .wrapper main form[name="login"] ~ a {
  display: none;
}

#body-login .logo {
  visibility: hidden;
}

#body-login #alternative-logins a.button[href*="oidc"] {
  background: #233b4a;
  color: #fff;
  transition: all 0.2s ease-in-out;
}
#body-login #alternative-logins a.button[href*="oidc"]:hover {
  background: linear-gradient(-35deg, #233b4a 40%, #486c83 100%);
}

#body-login #alternative-logins a.button[href*="/sociallogin/oauth/google"] {
  border: 0;
  color: #db4437 !important;
  background-color: #fff;
}

#body-login
  #alternative-logins
  a.button[href*="/sociallogin/oauth/google"]::before {
  width: 25px;
  background-color: #db4437;
  border-radius: 100%;
  background-size: 60%;
  background-position: center;
  height: 25px;
  vertical-align: middle;
  margin-right: 4px;
}

#body-login main {
  padding: 50vh 0 0 0;
}

#body-login a[href*="#body-login"] {
  visibility: hidden;
}

#body-login footer a,
#body-login footer p {
  color: #233b4a;
}

#body-login footer a:hover {
  color: #fff;
}

#body-login footer p.info {
  text-shadow: none;
}
```

## Drone

#### Generating deploy keys

We normally do something like the following.

```bash
ssh-keygen -t ed25519 -C drone@swarm.autonomic.zone
```

When you're loading them into Drone, make sure to use the right name of the organisation when using `drone orgsecret add`.

#### How to change orgsecret values

First, get your Drone CLI tool downloaded and the environment configured.

```bash
export DRONE_SERVER=https://drone.example.com
export DRONE_TOKEN=$(pass show your-pass-store-path)
curl -L https://github.com/drone/drone-cli/releases/latest/download/drone_linux_amd64.tar.gz | tar zx
```

Then you can do things like:

```
./drone orgsecret ls
./drone orgsecret add someorg my_deploy_key @my_private_key_file
```

#### How to enable build failure notifications

Add this to your `.drone.yml` file. See the [plugin docs](http://plugins.drone.io/drone-plugins/drone-slack/) for more.

```yaml
- name: notify rocket chat
  image: plugins/slack
  depends_on: ["mybuild"]
  settings:
    webhook:
      from_secret: rc_builds_url
    username: foobar
    channel: "builds"
    template: "{{repo.owner}}/{{repo.name}} build failed: {{build.link}}"
  when:
    status:
      - failure
```

!!! warning

    You must include valid names of pipelines in your `depends_on` list field.
    This is so that the notification will wait until all other pipelines are
    run before performing the notification logic.

#### Skipping CI builds

Add `[ci skip]` into the git commit message. You don't have to run builds if you don't want to.

## Peertube

#### How do I wire up Keycloak SSO?

Use [this plugin](https://framagit.org/framasoft/peertube/official-plugins/tree/master/peertube-plugin-auth-openid-connect).

#### How do I develop a custom theme?

See [this approach](https://git.autonomic.zone/ruangrupa/peertube-plugin-lumbung-space).
