Backing up 3scale API Management by using OADP¶

Back up Red Hat 3scale API Management components, including the 3scale Operator, MySQL database, and Redis database, by using OpenShift API for Data Protection (OADP). This helps you protect your API management infrastructure and provides recovery in case of data loss.

For more information about installing and configuring Red Hat 3scale API Management, see Installing 3scale API Management on OpenShift and Red Hat 3scale API Management.

Creating the Data Protection Application¶

Create a Data Protection Application (DPA) custom resource (CR) to configure backup storage and Velero settings for Red Hat 3scale API Management. This helps you set up the backup infrastructure required for protecting your 3scale components.

Procedure

Create a YAML file with the following configuration:

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: dpa-sample
  namespace: openshift-adp 
spec:
  configuration:
    velero:
      defaultPlugins:
        - openshift 
        - aws
        - csi
      resourceTimeout: 10m 
    nodeAgent: 
      enable: true 
      uploaderType: kopia 
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket_name>
          prefix: <prefix>
        config:
          region: <region>
          profile: "default"
          s3ForcePathStyle: "true"
          s3Url: <s3_url>
        credential:
          key: cloud
          name: cloud-credentials

where:

<bucket_name>: Specifies a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
<prefix>: Specifies a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
<region>: Specifies a region for backup storage location.
<s3_url>: Specifies the URL of the object store that you are using to store backups.

Create the DPA CR by running the following command:
```
$ oc create -f dpa.yaml
```

Backing up the 3scale API Management operator, secret, and APIManager¶

Back up the Red Hat 3scale API Management operator resources, including the Secret and APIManager custom resources (CRs), by creating backup CRs. This helps you preserve your 3scale operator configuration for recovery scenarios.

Prerequisites

You created the Data Protection Application (DPA).

Procedure

Back up your 3scale operator CRs, such as operatorgroup, namespaces, and subscriptions, by creating a YAML file with the following configuration:
```
apiVersion: velero.io/v1
kind: Backup
metadata:
  name: operator-install-backup
  namespace: openshift-adp
spec:
  csiSnapshotTimeout: 10m0s
  defaultVolumesToFsBackup: false
  includedNamespaces:
  - threescale
  includedResources:
  - operatorgroups
  - subscriptions
  - namespaces
  itemOperationTimeout: 1h0m0s
  snapshotMoveData: false
  ttl: 720h0m0s
```
where:

operator-install-backup

Specifies the value of the metadata.name parameter in the backup. This is the same value used in the metadata.backupName parameter used when restoring the 3scale operator.

threescale

Specifies the namespace where the 3scale operator is installed.

Note

You can also back up and restore ReplicationControllers, Deployment, and Pod objects to ensure that all manually set environments are backed up and restored. This does not affect the flow of restoration.

Create a backup CR by running the following command:

$ oc create -f backup.yaml

Example output

backup.velero.io/operator-install-backup created

Back up the Secret CR by creating a YAML file with the following configuration:

apiVersion: velero.io/v1
kind: Backup
metadata:
  name: operator-resources-secrets
  namespace: openshift-adp
spec:
  csiSnapshotTimeout: 10m0s
  defaultVolumesToFsBackup: false
  includedNamespaces:
  - threescale
  includedResources:
  - secrets
  itemOperationTimeout: 1h0m0s
  labelSelector:
    matchLabels:
      app: 3scale-api-management
  snapshotMoveData: false
  snapshotVolumes: false
  ttl: 720h0m0s

name: Specifies the value of the metadata.name parameter in the backup. Use this value in the metadata.backupName parameter when restoring the Secret.

Create the Secret backup CR by running the following command:

$ oc create -f backup-secret.yaml

Example output

backup.velero.io/operator-resources-secrets created

Back up the APIManager CR by creating a YAML file with the following configuration:

apiVersion: velero.io/v1
kind: Backup
metadata:
  name: operator-resources-apim
  namespace: openshift-adp
spec:
  csiSnapshotTimeout: 10m0s
  defaultVolumesToFsBackup: false
  includedNamespaces:
  - threescale
  includedResources:
  - apimanagers
  itemOperationTimeout: 1h0m0s
  snapshotMoveData: false
  snapshotVolumes: false
  storageLocation: ts-dpa-1
  ttl: 720h0m0s
  volumeSnapshotLocations:
  - ts-dpa-1

name: Specifies the value of the metadata.name parameter in the backup. Use this value in the metadata.backupName parameter when restoring the APIManager.

Create the APIManager CR by running the following command:

$ oc create -f backup-apimanager.yaml

Example output

backup.velero.io/operator-resources-apim created

Backing up a MySQL database¶

Back up a MySQL database by creating a persistent volume claim (PVC) to store the database dump. This helps you preserve your 3scale system database data for recovery scenarios.

Prerequisites

You have backed up the Red Hat 3scale API Management operator.

Procedure

Create a YAML file with the following configuration for adding an additional PVC:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: example-claim
  namespace: threescale
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: gp3-csi
  volumeMode: Filesystem

Create the additional PVC by running the following command:
```
$ oc create -f ts_pvc.yml 
```

Attach the PVC to the system database pod by editing the system-mysql deployment to use the MySQL dump:

$ oc edit deployment system-mysql -n threescale

  volumeMounts:
    - name: example-claim
      mountPath: /var/lib/mysqldump/data
    - name: mysql-storage
      mountPath: /var/lib/mysql/data
    - name: mysql-extra-conf
      mountPath: /etc/my-extra.d
    - name: mysql-main-conf
      mountPath: /etc/my-extra
    ...
      serviceAccount: amp
  volumes:
        - name: example-claim
          persistentVolumeClaim:
            claimName: example-claim
    ...

claimName: Specifies the PVC that contains the dumped data.

Create a YAML file with following configuration to back up the MySQL database:

apiVersion: velero.io/v1
