Backup Druid using KubeStash Auto-Backup
KubeStash can automatically be configured to backup any Druid databases in your cluster. KubeStash enables cluster administrators to deploy backup blueprints ahead of time so database owners can easily backup any Druid database with a few annotations.
In this tutorial, we are going to show how you can configure a backup blueprint for Druid databases in your cluster and backup them with a few annotations.
Before You Begin
- At first, you need to have a Kubernetes cluster, and the
kubectlcommand-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by usingMinikubeorKind. - Now, install KubeDB cli on your workstation and KubeDB operator in your cluster following the steps here and make sure to include the flags
--set global.featureGates.Druid=trueto ensure Druid CRD and--set global.featureGates.ZooKeeper=trueto ensure ZooKeeper CRD as Druid depends on ZooKeeper for external dependency with helm command. - Install
KubeStashin your cluster following the steps here. - Install KubeStash
kubectlplugin following the steps here. - If you are not familiar with how KubeStash backup and restore Druid databases, please check the following guide here.
You should be familiar with the following KubeStash concepts:
To keep everything isolated, we are going to use a separate namespace called demo throughout this tutorial.
$ kubectl create ns demo
namespace/demo created
Prepare Backend
We are going to store our backed up data into a GCS bucket. We have to create a Secret with necessary credentials and a BackupStorage CR to use this backend. If you want to use a different backend, please read the respective backend configuration doc from here.
Create Secret:
Let’s create a secret called gcs-secret with access credentials to our desired GCS bucket,
$ echo -n '<your-project-id>' > GOOGLE_PROJECT_ID
$ cat /path/to/downloaded-sa-key.json > GOOGLE_SERVICE_ACCOUNT_JSON_KEY
$ kubectl create secret generic -n demo gcs-secret \
--from-file=./GOOGLE_PROJECT_ID \
--from-file=./GOOGLE_SERVICE_ACCOUNT_JSON_KEY
secret/gcs-secret created
Create BackupStorage:
Now, create a BackupStorage using this secret. Below is the YAML of BackupStorage CR we are going to create,
apiVersion: storage.kubestash.com/v1alpha1
kind: BackupStorage
metadata:
name: gcs-storage
namespace: demo
spec:
storage:
provider: gcs
gcs:
bucket: kubestash-qa
prefix: blueprint
secretName: gcs-secret
usagePolicy:
allowedNamespaces:
from: All
default: true
deletionPolicy: Delete
Let’s create the BackupStorage we have shown above,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/backupstorage.yaml
backupstorage.storage.kubestash.com/gcs-storage created
Create RetentionPolicy:
Now, let’s create a RetentionPolicy to specify how the old Snapshots should be cleaned up.
Below is the YAML of the RetentionPolicy object that we are going to create,
apiVersion: storage.kubestash.com/v1alpha1
kind: RetentionPolicy
metadata:
name: demo-retention
namespace: demo
spec:
default: true
failedSnapshots:
last: 2
maxRetentionPeriod: 2mo
successfulSnapshots:
last: 5
usagePolicy:
allowedNamespaces:
from: All
Let’s create the above RetentionPolicy,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/retentionpolicy.yaml
retentionpolicy.storage.kubestash.com/demo-retention created
Create Secret:
We also need to create a secret with a Restic password for backup data encryption.
Let’s create a secret called encrypt-secret with the Restic password,
$ echo -n 'changeit' > RESTIC_PASSWORD
$ kubectl create secret generic -n demo encrypt-secret \
--from-file=./RESTIC_PASSWORD
secret "encrypt-secret" created
Auto-backup with default configurations
In this section, we are going to backup a Druid database of demo namespace. We are going to use the default configurations which will be specified in the Backup Blueprint CR.
Prepare Backup Blueprint
A BackupBlueprint allows you to specify a template for the Repository,Session or Variables of BackupConfiguration in a Kubernetes native way.
Now, we have to create a BackupBlueprint CR with a blueprint for BackupConfiguration object.
apiVersion: core.kubestash.com/v1alpha1
kind: BackupBlueprint
metadata:
name: druid-default-backup-blueprint
namespace: demo
spec:
usagePolicy:
allowedNamespaces:
from: All
backupConfigurationTemplate:
deletionPolicy: OnDelete
backends:
- name: gcs-backend
storageRef:
namespace: demo
name: gcs-storage
retentionPolicy:
name: demo-retention
namespace: demo
sessions:
- name: frequent-backup
sessionHistoryLimit: 3
scheduler:
schedule: "*/5 * * * *"
jobTemplate:
backoffLimit: 1
repositories:
- name: default-blueprint
backend: gcs-backend
directory: /default-blueprint
encryptionSecret:
name: encrypt-secret
namespace: demo
addon:
name: druid-addon
tasks:
- name: mysql-metadata-storage-backup
Here,
.spec.backupConfigurationTemplate.backends[*].storageRefrefers to our earlier createdgcs-storagebackupStorage..spec.backupConfigurationTemplate.sessions[*].schedulespecifies that we want to backup the database at5 minutesinterval.
Let’s create the BackupBlueprint we have shown above,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/default-backupblueprint.yaml
backupblueprint.core.kubestash.com/druid-default-backup-blueprint created
Now, we are ready to backup our Druid databases using a few annotations.
Deploy Sample Druid Database
Create External Dependency (Deep Storage):
One of the external dependency of Druid is deep storage where the segments are stored. It is a storage mechanism that Apache Druid does not provide. Amazon S3, Google Cloud Storage, or Azure Blob Storage, S3-compatible storage (like Minio), or HDFS are generally convenient options for deep storage.
In this tutorial, we will run a minio-server as deep storage in our local kind cluster using minio-operator and create a bucket named druid in it, which the deployed druid database will use.
$ helm repo add minio https://operator.min.io/
$ helm repo update minio
$ helm upgrade --install --namespace "minio-operator" --create-namespace "minio-operator" minio/operator --set operator.replicaCount=1
$ helm upgrade --install --namespace "demo" --create-namespace druid-minio minio/tenant \
--set tenant.pools[0].servers=1 \
--set tenant.pools[0].volumesPerServer=1 \
--set tenant.pools[0].size=1Gi \
--set tenant.certificate.requestAutoCert=false \
--set tenant.buckets[0].name="druid" \
--set tenant.pools[0].name="default"
Now we need to create a Secret named deep-storage-config. It contains the necessary connection information using which the druid database will connect to the deep storage.
apiVersion: v1
kind: Secret
metadata:
name: deep-storage-config
namespace: demo
stringData:
druid.storage.type: "s3"
druid.storage.bucket: "druid"
druid.storage.baseKey: "druid/segments"
druid.s3.accessKey: "minio"
druid.s3.secretKey: "minio123"
druid.s3.protocol: "http"
druid.s3.enablePathStyleAccess: "true"
druid.s3.endpoint.signingRegion: "us-east-1"
druid.s3.endpoint.url: "http://myminio-hl.demo.svc.cluster.local:9000/"
Let’s create the deep-storage-config Secret shown above:
$ kubectl create -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/deep-storage-config.yaml
secret/deep-storage-config created
Let’s deploy a sample Druid database and insert some data into it.
Create Druid CR:
Below is the YAML of a sample Druid CRD that we are going to create for this tutorial:
apiVersion: kubedb.com/v1alpha2
kind: Druid
metadata:
name: sample-druid
namespace: demo
annotations:
blueprint.kubestash.com/name: druid-default-backup-blueprint
blueprint.kubestash.com/namespace: demo
spec:
version: 30.0.0
deepStorage:
type: s3
configSecret:
name: deep-storage-config
topology:
routers:
replicas: 1
deletionPolicy: WipeOut
Here,
.spec.annotations.blueprint.kubestash.com/name: druid-default-backup-blueprintspecifies the name of theBackupBlueprintthat will use in backup..spec.annotations.blueprint.kubestash.com/namespace: demospecifies the name of thenamespacewhere theBackupBlueprintresides.
Create the above Druid CR,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/sample-druid.yaml
druid.kubedb.com/sample-druid created
Verify BackupConfiguration
If everything goes well, KubeStash should create a BackupConfiguration for our Druid in demo namespace and the phase of that BackupConfiguration should be Ready. Verify the BackupConfiguration object by the following command,
$ kubectl get backupconfiguration -n demo
NAME PHASE PAUSED AGE
appbinding-sample-druid Ready 8m48s
Now, let’s check the YAML of the BackupConfiguration.
$ kubectl get backupconfiguration -n demo appbinding-sample-druid -o yaml

Notice the spec.backends, spec.sessions and spec.target sections, KubeStash automatically resolved those info from the BackupBluePrint and created above BackupConfiguration.
Verify BackupSession:
KubeStash triggers an instant backup as soon as the BackupConfiguration is ready. After that, backups are scheduled according to the specified schedule.
$ kubectl get backupsession -n demo -w
NAME INVOKER-TYPE INVOKER-NAME PHASE DURATION AGE
appbinding-sample-druid-frequent-backup-1726741846 BackupConfiguration appbinding-sample-druid Succeeded 28s 10m
appbinding-sample-druid-frequent-backup-1726742101 BackupConfiguration appbinding-sample-druid Succeeded 35s 6m37s
appbinding-sample-druid-frequent-backup-1726742400 BackupConfiguration appbinding-sample-druid Succeeded 29s 98s
We can see from the above output that the backup session has succeeded. Now, we are going to verify whether the backed up data has been stored in the backend.
Verify Backup:
Once a backup is complete, KubeStash will update the respective Repository CR to reflect the backup. Check that the repository default-blueprint has been updated by the following command,
$ kubectl get repository -n demo default-blueprint
NAME INTEGRITY SNAPSHOT-COUNT SIZE PHASE LAST-SUCCESSFUL-BACKUP AGE
default-blueprint true 3 1.757 MiB Ready 2m23s 11m
At this moment we have one Snapshot. Run the following command to check the respective Snapshot which represents the state of a backup run for an application.
$ kubectl get snapshots -n demo -l=kubestash.com/repo-name=default-blueprint
NAME REPOSITORY SESSION SNAPSHOT-TIME DELETION-POLICY PHASE AGE
default-blueprint-appbinding-samruid-frequent-backup-1726741846 default-blueprint frequent-backup 2024-09-19T10:30:56Z Delete Succeeded 11m

default-blueprint-appbinding-samruid-frequent-backup-1726742400 default-blueprint frequent-backup 2024-09-19T10:40:00Z Delete Succeeded 2m50s
Note: KubeStash creates a
Snapshotwith the following labels:
kubestash.com/app-ref-kind: <target-kind>kubestash.com/app-ref-name: <target-name>kubestash.com/app-ref-namespace: <target-namespace>kubestash.com/repo-name: <repository-name>These labels can be used to watch only the
Snapshots related to our target Database orRepository.
If we check the YAML of the Snapshot, we can find the information about the backed up components of the Database.

KubeStash uses the
mysqldump/postgresdumpcommand to take backups of metadata storage of target Druid databases. Therefore, the component name forlogical backupsis set asdump.
Now, if we navigate to the GCS bucket, we will see the backed up data stored in the /blueprint/default-blueprint/repository/v1/frequent-backup/dump directory. KubeStash also keeps the backup for Snapshot YAMLs, which can be found in the blueprint/default-blueprintrepository/snapshots directory.
Note: KubeStash stores all dumped data encrypted in the backup directory, meaning it remains unreadable until decrypted.
Auto-backup with custom configurations
In this section, we are going to backup a Druid database of demo namespace. We are going to use the custom configurations which will be specified in the BackupBlueprint CR.
Prepare Backup Blueprint
A BackupBlueprint allows you to specify a template for the Repository,Session or Variables of BackupConfiguration in a Kubernetes native way.
Now, we have to create a BackupBlueprint CR with a blueprint for BackupConfiguration object.
apiVersion: core.kubestash.com/v1alpha1
kind: BackupBlueprint

namespace: demo
spec:

params:
databases: ${targetedDatabases}
Note that we have used some variables (format: ${<variable name>}) in different fields. KubeStash will substitute these variables with values from the respective target’s annotations. You’re free to use any variables you like.
Here,
.spec.backupConfigurationTemplate.backends[*].storageRefrefers our earlier createdgcs-storagebackupStorage..spec.backupConfigurationTemplate.sessions[*]:.scheduledefines${schedule}variable, which determines the time interval for the backup..repositories[*].namedefines the${repoName}variable, which specifies the name of the backupRepository..repositories[*].directorydefines two variables,${namespace}and${targetName}, which are used to determine the path where the backup will be stored..addon.tasks[*]databasesdefines${targetedDatabases}variable, which identifies list of databases to backup.
Note: To create
BackupBlueprintfor druid withPostgreSQLas metadata storage just updatespec.sessions[*].addon.tasks.nametopostgres-metadata-storage-restore
Let’s create the BackupBlueprint we have shown above,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/customize-backupblueprint.yaml
backupblueprint.core.kubestash.com/druid-customize-backup-blueprint created
Now, we are ready to backup our Druid databases using few annotations. You can check available auto-backup annotations for a databases from here.
Create Database
Before proceeding to creating a new Druid database, let us clean up the resources of the previous step:
kubectl delete backupblueprints.core.kubestash.com -n demo druid-default-backup-blueprint
kubectl delete druid -n demo sample-druid
Now, we are going to create a new Druid CR in demo namespace. Below is the YAML of the Druid object that we are going to create,
apiVersion: kubedb.com/v1alpha2
kind: Druid
metadata:
name: sample-druid-2

Notice the metadata.annotations field, where we have defined the annotations related to the automatic backup configuration. Specifically, we’ve set the BackupBlueprint name as druid-customize-backup-blueprint and the namespace as demo. We have also provided values for the blueprint template variables, such as the backup schedule, repositoryName, namespace, targetName, and targetedDatabases. These annotations will be used to create a BackupConfiguration for this Druid database.
Let’s create the Druid we have shown above,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2024.11.18/docs/guides/druid/backup/auto-backup/examples/sample-druid-2.yaml

We can see from the above output that the backup session has succeeded. Now, we are going to verify whether the backed up data has been stored in the backend.
Verify Backup:
Once a backup is complete, KubeStash will update the respective Repository CR to reflect the backup. Check that the repository customize-blueprint has been updated by the following command,
$ kubectl get repository -n demo customize-blueprint

Now, if we navigate to the GCS bucket, we will see the backed up data stored in the /blueprint/custom-blueprint/repository/v1/frequent-backup/dump directory. KubeStash also keeps the backup for Snapshot YAMLs, which can be found in the blueprint/custom-blueprint/snapshots directory.
Note: KubeStash stores all dumped data encrypted in the backup directory, meaning it remains unreadable until decrypted.
