Microsoft Azure Storage
Stash supports Microsoft Azure Storage as a backend. This tutorial will show you how to configure Restic and storage Secret for Azure Storage.
Create Storage Secret
To configure storage secret for this backend, following secret keys are needed:
| Key | Description |
|---|---|
RESTIC_PASSWORD | Required. Password used to encrypt snapshots by restic |
AZURE_ACCOUNT_NAME | Required. Azure Storage account name |
AZURE_ACCOUNT_KEY | Required. Azure Storage account key |
Create storage secret as below,
$ echo -n 'changeit' > RESTIC_PASSWORD
$ echo -n '<your-azure-storage-account-name>' > AZURE_ACCOUNT_NAME
$ echo -n '<your-azure-storage-account-key>' > AZURE_ACCOUNT_KEY
$ kubectl create secret generic azure-secret \
--from-file=./RESTIC_PASSWORD \
--from-file=./AZURE_ACCOUNT_NAME \
--from-file=./AZURE_ACCOUNT_KEY
secret "azure-secret" created
Verify that the secret has been created with respective keys,
$ kubectl get secret azure-secret -o yaml
apiVersion: v1
data:
AZURE_ACCOUNT_KEY: PHlvdXItYXp1cmUtc3RvcmFnZS1hY2NvdW50LWtleT4=
AZURE_ACCOUNT_NAME: PHlvdXItYXp1cmUtc3RvcmFnZS1hY2NvdW50LW5hbWU+
RESTIC_PASSWORD: Y2hhbmdlaXQ=
kind: Secret

Configure Restic
Now, you have to configure Restic crd to use Azure Storage. You have to provide previously created storage secret in spec.backend.storageSecretName field.
Following parameters are available for Azure backend.
| Parameter | Description |
|---|---|
azure.container | Required. Name of Storage container |
azure.prefix | Optional. Path prefix into bucket where repository will be created. |
Below, the YAML for Restic crd configured to use Azure Storage.
apiVersion: stash.appscode.com/v1alpha1
kind: Restic
metadata:
name: azure-restic
namespace: default
spec:
selector:
matchLabels:
app: azure-restic
fileGroups:
- path: /source/data
retentionPolicyName: 'keep-last-5'
backend:
azure:
container: stashqa
prefix: demo
storageSecretName: azure-secret
schedule: '@every 1m'
volumeMounts:
- mountPath: /source/data
name: source-data
retentionPolicies:
- name: 'keep-last-5'
keepLast: 5

Now, create the Restic we have configured above for azure backend,
$ kubectl apply -f https://github.com/stashed/docs/raw/v0.9.0-rc.4/docs/examples/backends/azure/azure-restic.yaml
restic "azure-restic" created
