# Rundeck Vault Storage Plugin

## Purpose
This is a [Storage Backend](https://docs.rundeck.com/docs/administration/security/key-storage.html#key-data-storage-converter) plugin for storing Key Store data in [Vault](https://www.vaultproject.io/).

This plugin is bundled with Rundeck Enterprise.  It is also available to Community users following the install steps below.

```
Default value: rundeck

* **engineVersion**: Vault Engine Version Key/Value Secret Engine Config

```
rundeck.storage.provider.[index].config.engineVersion=1/2
```

Default value: 1

* **useVaultMetadataTimestamps**: When `true` and **engineVersion** is `2`, the plugin reads the KV v2 **metadata** endpoint (`<mount>/metadata/...`) for secrets that have been updated more than once (`version > 1`), so Rundeck can show the **original** creation time and the **real** last-modified time. Requires `read` on `<mount>/metadata/*` in Vault policy. If the metadata call fails (e.g. missing permission), behavior falls back to the previous timestamps. For `version == 1`, no extra Vault call is made.

```
rundeck.storage.provider.[index].config.useVaultMetadataTimestamps=true
```

Default value: `false` (opt-in).

### Configuration Examples

#### **example basic settings**
```
rundeck.storage.provider.1.type=vault-storage
rundeck.storage.provider.1.path=keys
rundeck.storage.provider.1.config.prefix=rundeck
rundeck.storage.provider.1.config.secretBackend=secret
rundeck.storage.provider.1.config.address=$VAULT_URL
rundeck.storage.provider.1.config.token=$VAULT_TOKEN
```

#### **existing vault storage**

For existing vault storage, probably you will need to remove the default `keys` path added by default for rundeck.
You can use these settings for an existing vault storage:

```
rundeck.storage.provider.1.type=vault-storage
rundeck.storage.provider.1.path=keys
rundeck.storage.provider.1.config.prefix=someprefix
rundeck.storage.provider.1.config.secretBackend=mybackend
rundeck.storage.provider.1.config.address=$VAULT_URL
rundeck.storage.provider.1.config.token=$VAULT_TOKEN
rundeck.storage.provider.1.config.storageBehaviour=vault
```

#### **Using APPROLE authentication**

You can use these settings for an existing vault storage:

#auth
rundeck.storage.provider.1.config.authBackend=approle
rundeck.storage.provider.1.config.approleAuthMount=approle
rundeck.storage.provider.1.config.approleId=$VAULT_APPROLE_ID
rundeck.storage.provider.1.config.approleSecretId=$VAULT_APPROLE_SECRET_ID

#timeouts
rundeck.storage.provider.1.config.maxRetries=500
rundeck.storage.provider.1.config.retryIntervalMilliseconds=2
rundeck.storage.provider.1.config.openTimeout=2500
rundeck.storage.provider.1.config.readTimeout=2500
```

**Enabling APPROLE Vault using API**

```
curl --header "X-Vault-Token: $TOKEN" --request POST --data '{"type": "approle"}' http://localhost:8200/v1/sys/auth/approle
curl --header "X-Vault-Token: $TOKEN" --request POST --data '{"policies": "rundeck", "token_ttl": "2m", "token_max_ttl": "2m"}' http://localhost:8200/v1/auth/approle/role/rundeck
# get $VAULT_APPROLE_ID
curl --header "X-Vault-Token: $TOKEN" http://localhost:8200/v1/auth/approle/role/rundeck/role-id | jq
# get $VAULT_APPROLE_SECRET_ID
curl --header "X-Vault-Token: $TOKEN" --request POST http://localhost:8200/v1/auth/approle/role/rundeck/secret-id | jq
```

#### **Using CERT authentication**

```
rundeck.storage.provider.1.type=vault-storage
rundeck.storage.provider.1.path=keys
rundeck.storage.provider.1.config.prefix=app
rundeck.storage.provider.1.config.address=$VAULT_URL
rundeck.storage.provider.1.config.authBackend=cert
rundeck.storage.provider.1.config.secretBackend=kv
rundeck.storage.provider.1.config.engineVersion=2
rundeck.storage.provider.1.config.certAuthMount=tls-auth
rundeck.storage.provider.1.config.keyStoreFile=$KEYSTORE_FILE
rundeck.storage.provider.1.config.keyStoreFilePassword=$KEYSTORE_PASSWORD
rundeck.storage.provider.1.config.trustStoreFile=$TRUSTSTORE_FILE
rundeck.storage.provider.1.config.truststoreFilePassword=$TRUSTSTORE_PASSWORD
rundeck.storage.provider.1.config.validateSsl=true
```
## Vault API versions

Since version 1.3.1, this plugin can work with `kV Secrets Engine - Version 2`. 
A new config variable was added in order to set the API version that you need to use:

rundeck.storage.provider.1.config.engineVersion=1/2

* engineVersion=1 will work with vault version 0.x
* engineVersion=2 will work with vault version 1.x

Example:

```
rundeck.storage.provider.1.type=vault-storage
rundeck.storage.provider.1.path=keys
rundeck.storage.provider.1.config.prefix=rundeck
rundeck.storage.provider.1.config.secretBackend=secret
rundeck.storage.provider.1.config.address=$VAULT_URL
rundeck.storage.provider.1.config.token=$VAULT_TOKEN
rundeck.storage.provider.1.config.engineVersion=2
```

By default, the value is set to v1 (1)

## Minimal version requirements
  * Java 1.8
  * Rundeck 2.10.0
  * Vault 0.9.0

## Thanks
  * [BetterCloud/vault-java-driver](https://github.com/BetterCloud/vault-java-driver) made this possible.

## TODO
  * Automated auth token lease renewal
  * Storage converter plugin
