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

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
