Microsoft Azure Storage
Stash supports Microsoft’s Azure Blob Storage as a backend. This tutorial will show you how to use this backend.
In order to use Azure Blob Storage as backend, you have to create a Secret and a Repository object pointing to the desired blob container.
Create Storage Secret
To configure storage secret for this backend, following secret keys are needed:
| Key | Type | Description |
|---|---|---|
RESTIC_PASSWORD | Required | Password that will be used to encrypt the backup snapshots |
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 -n demo azure-secret \
--from-file=./RESTIC_PASSWORD \
--from-file=./AZURE_ACCOUNT_NAME \
--from-file=./AZURE_ACCOUNT_KEY
secret/azure-secret created
Create Repository
Now, you have to create a Repository crd. You have to provide the storage secret that we have created earlier in spec.backend.storageSecretName field.
Following parameters are available for azure backend.
| Parameter | Type | Description |
|---|---|---|
azure.container | Required | Name of Storage container. |
azure.prefix | Optional | Path prefix inside the container where backed up data will be stored. |
azure.maxConnections | Optional | Maximum number of parallel connections to use for uploading backup data. By default, Stash will use maximum 5 parallel connections. |
Below, the YAML of a sample Repository crd that uses an Azure Blob container as a backend.
apiVersion: stash.appscode.com/v1alpha1
kind: Repository
metadata:
name: azure-repo
namespace: demo
spec:
backend:
azure:
container: stash-backup
prefix: /demo/deployment/my-deploy
storageSecretName: azure-secret
Create the Repository we have shown above using the following command,
$ kubectl apply -f https://github.com/stashed/docs/raw/v2022.07.09/docs/examples/guides/backends/azure.yaml
repository/azure-repo created
Now, we are ready to use this backend to backup our desired data using Stash.
