# MOLGENIS Vault helm chart
|
||||
|
||||
This chart creates a vault operator, but NO vault.
|
||||
The vault operator defines a new custom resource named `vault` that you can use to create vaults.
|
||||
|
||||
After launching the operator, create the molgenis vault manually:
|
||||
`kubectl create -f resources/vault.yaml`
|
||||
|
||||
That creates a new vault with two vault pods.
|
||||
|
||||
See https://github.com/coreos/vault-operator/blob/master/doc/user/vault.md
|
||||
|
||||
The UI will be exposed on the host name you specify.
|
||||
|
||||
## Parameters
|
||||
|
||||
### Azure cloud credentials
|
||||
Define credentials for backup to the Azure Blob Store.
|
||||
See [etcd-operator documentation](https://github.com/coreos/etcd-operator/blob/master/doc/user/abs_backup.md).
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| --------------- | ----------------------------- | ------------------ |
|
||||
| `abs.account` | name of storage account | `fdlkops` |
|
||||
| `abs.accessKey` | access key of storage account | `xxxx` |
|
||||
| `abs.cloud` | name of cloud environment | `AzurePublicCloud` |
