There is no automatic backup enabled for buckets.

You can request a Google Cloud Storage bucket through the NAIS manifest.

apiVersion: ""
kind: "Application"
  name: app-a
      - name: mybucket
        retentionPeriodDays: 30
          age: 7
          createdBefore: 2020-01-01
          numNewerVersions: 2
          withState: ANY


Once a bucket is provisioned, it will not be automatically deleted unless one explicitly sets spec.gcp.buckets[].cascadingDelete to true. This means that any cleanup must be done manually.

Bucket names must be globally unique across the entire Google infrastructure. This can cause provisioning problems if your bucket name is used by someone else.

RetentionPeriodDays and lifecycleCondition must be set when creating the bucket as they cannot be changed after the bucket is created.

RetentionPeriodDays is set in number of days, if not set; no retention policy will be set and files can be deleted by application or manually from the point they are created.

LifecycleCondition can be set to verify which files/objects are subject to permanent deletion based on the conditions set.

  • age specifies days it has existed in the bucket before it can be deleted.
  • createdBefore specifies a date all files created before this date can be deleted.
  • numNewerVersions specifies the number of revisions that must be kept, all older revisions can be deleted.
  • withState specifies which state (LIVE, ARCHIVED, ANY) the object must have before being subject to permanent deletion.

The latter two are subject to object versioning being set on objects, as unversioned objects do not have multiple versions and have state value LIVE.

If you have problems getting your bucket up and running, check errors in the event log:

kubectl describe storagebucket mybucket
