# Server configuration

## User registration

Woodpecker does not have its own user registry; users are provided from your [forge](./11-forges/11-overview.md) (using OAuth2).

Registration is closed by default (`WOODPECKER_OPEN=false`). If registration is open (`WOODPECKER_OPEN=true`) then every user with an account at the configured forge can login to Woodpecker.

To open registration:

```ini
WOODPECKER_OPEN=true
```

You can **also restrict** registration, by keep registration closed and:

- **adding** new **users manually** via the CLI: `woodpecker-cli user add`
- allowing specific **admin users** via the `WOODPECKER_ADMIN` setting
- by open registration and **filter by organization** membership through the `WOODPECKER_ORGS` setting

### Close registration, but allow specific admin users

```ini
WOODPECKER_OPEN=false
WOODPECKER_ADMIN=johnsmith,janedoe
```

### Only allow registration of users, who are members of approved organizations

```ini
WOODPECKER_OPEN=true
WOODPECKER_ORGS=dolores,dogpatch
```

## Administrators

Administrators should also be enumerated in your configuration.

```ini
WOODPECKER_ADMIN=johnsmith,janedoe
```

## Filtering repositories

Woodpecker operates with the user's OAuth permission. Due to the coarse permission handling of GitHub, you may end up syncing more repos into Woodpecker than preferred.

Use the `WOODPECKER_REPO_OWNERS` variable to filter which GitHub user's repos should be synced only. You typically want to put here your company's GitHub name.

```ini
WOODPECKER_REPO_OWNERS=mycompany,mycompanyossgithubuser
```

## Global registry setting

If you want to make available a specific private registry to all pipelines, use the `WOODPECKER_DOCKER_CONFIG` server configuration.
Point it to your server's docker config.

```ini
WOODPECKER_DOCKER_CONFIG=/root/.docker/config.json
```

## Handling sensitive data in docker-compose and docker-swarm

To handle sensitive data in docker-compose or docker-swarm configurations there are several options:

For docker-compose you can use a `.env` file next to your compose configuration to store the secrets outside of the compose file. While this separates configuration from secrets it is still not very secure.

Alternatively use docker-secrets. As it may be difficult to use docker secrets for environment variables Woodpecker allows to read sensible data from files by providing a `*_FILE` option of all sensible configuration variables. Woodpecker will try to read the value directly from this file. Keep in mind that when the original environment variable gets specified at the same time it will override the value read from the file.

```diff title="docker-compose.yaml"
 version: '3'

 services:
   woodpecker-server:
     [...]
     environment:
       - [...]
+      - WOODPECKER_AGENT_SECRET_FILE=/run/secrets/woodpecker-agent-secret
+    secrets:
+      - woodpecker-agent-secret
+
+ secrets:
+   woodpecker-agent-secret:
+     external: true
```

Store a value to a docker secret like this:

```bash
echo "my_agent_secret_key" | docker secret create woodpecker-agent-secret -
```

or generate a random one like this:

```bash
openssl rand -hex 32 | docker secret create woodpecker-agent-secret -
```

## Custom JavaScript and CSS

Woodpecker supports custom JS and CSS files.
These files must be present in the server's filesystem.
They can be backed in a Docker image or mounted from a ConfigMap inside a Kubernetes environment.
The configuration variables are independent of each other, which means it can be just one file present, or both.

```ini
WOODPECKER_CUSTOM_CSS_FILE=/usr/local/www/woodpecker.css
WOODPECKER_CUSTOM_JS_FILE=/usr/local/www/woodpecker.js
```

The examples below show how to place a banner message in the top navigation bar of Woodpecker.

### `woodpecker.css`

```css
.banner-message {
  position: absolute;
  width: 280px;
  height: 40px;
  margin-left: 240px;
  margin-top: 5px;
  padding-top: 5px;
  font-weight: bold;
  background: red no-repeat;
  text-align: center;
}
```

### `woodpecker.js`

```javascript
// place/copy a minified version of jQuery or ZeptoJS here ...
!(function () {
  'use strict';
  function e() {} /*...*/
})();

$().ready(function () {
  $('.app nav img').first().htmlAfter("<div class='banner-message'>This is a demo banner message :)</div>");
});
```
