NetBackup™ Deployment Guide for Azure Kubernetes Services (AKS) Cluster

name:environment-sample

Specify the name of the environment in your cluster.

namespace: example-ns

Specify the namespace where all the NetBackup resources are managed. If not specified here, then it will be the current namespace when you run the command kubectl apply -f on this file.

containerRegistry: example.azurecr.io

Specify a container registry that the cluster has access. NetBackup images are pushed to this registry.

tag: '10.0.0.1'

This tag is used for all images in the environment. Specifying a `tag` value on a sub-resource affects the images for that sub-resource only. For example, if you apply an EEB that affects only primary servers, you might set the `primary.tag` to the custom tag of that EEB. The primary server runs with that image, but the media servers and MSDP scaleouts continue to run images tagged `10.0.0.1`. Beware that the values that look like numbers are treated as numbers in YAML even though this field needs to be a string; quote this to avoid misinterpretation.

licenseKeys:

List the license keys that are shared among all the sub-resources. Licenses specified in a sub-resource are appended to this list and applied only to the sub-resource.

paused: false

Specify whether the NetBackup operator attempts to reconcile the differences between this YAML specification and the current Kubernetes cluster state. Only set it to true during maintenance.

configCheckMode: default

This controls whether certain configuration restrictions are checked or enforced during setup. Other allowed values are skip and dryrun.

corePattern: /corefiles/core.%e.%p.%t

Specify the path to use for storing core files in case of a crash.

loadBalancerAnnotations: service. beta.kubernetes.io/ azure-load- balancer- internal-subnet:

example-subnet

Specify the annotations to be added for the network load balancer

paused: false

Specifies whether the NetBackup operator attempts to reconcile the differences between this YAML specification and the current Kubernetes cluster state. Set it to true only during maintenance. This applies only to the environment object. To pause reconciliation of the managed primary server, for example, you must set spec.primary.paused. Setting spec.paused:true ceases updates to the managed resources, including updates to their `paused` status. Entries in the media servers and MSDP scaleouts lists also support the `paused` field. The default value is false.

primary

Specifies attributes specific to the primary server resources. Every environment has exactly one primary server, so this section cannot be left blank.

resourceNamePrefix: primary-name

Set resourceNamePrefix to control the name of the primary server. The default value is the same as the environment's name.

tag: 10.0.0.1-special

To use a different image tag specifically for the primary server, uncomment this value and provide the desired tag. This overrides the tag specified in the common section.

nodeSelector:

labelKey: kubernetes.io/os

labelValue: linux

Specify a key and value that identifies nodes where the primary server pod runs.

networkLoadBalancer:

annotations: service.beta. kubernetes.io / azure-load- balancer-internal- subnet: example- subnet

ipList:
        - ipAddr: 4.3.2.1
          fqdn: primary.example.com

Uncomment the annotations to specify additional primary server-specific annotations. These values are merged with the values given in the loadBalancerAnnotations above. Any duplicate values given here override the corresponding values above.

Next, specify the hostname and IP address of the primary server.

credSecretName: primary-credential-secret

This determines the credentials for the primary server. Media servers use these credentials to register themselves with the primary server.

itAnalyticsPublicKey: ssh-rsaxxx

If using NetBackup IT Analytics, uncomment this and provide the SSH public key. IT Analytics uses this to access the primary server.

kmsDBSecret: kms-secret

Secret name which contains the Host Master Key ID (HMKID), Host Master Key passphrase (HMKpassphrase), Key Protection Key ID (KPKID) and Key Protection Key passphrase (KPKpassphrase) for NetBackup Key Management Service. The secret should be 'Opaque', and can be created either using a YAML or the following example command: kubectl create secret generic kms-secret --namespace nb-namespace --from-literal=HMKID="HMK@ID" --from-literal=HMKpassphrase="HMK@passphrase" --from-literal=KPKID="KPK@ID" --from-literal=KPKpassphrase="KPK@passphrase"

licenseKeys:

To specify additional license keys that are applied only to the primary server, uncomment this and provide the license key(s). In this example, the primary server would have the "X" license key defined in the previous section, followed by this "Y" key.

catalog:

capacity: 100Gi

storageClassName: standard

This storage applies to the primary server for the NetBackup catalog and log volumes. The primary server catalog volume must be at least 100 Gi.

log:

capacity: 30Gi

storageClassName: standard

Log volume must be at least 30Gi.

mediaServers:

- resourceNamePrefix: media1

This specifies media server configurations. This is given as a list of media servers, but most environments will have just one, with multiple replicas. It's also possible to have zero media servers; in that case, either remove the media servers section entirely, or define it as an empty list: mediaServers: []

replicas: 1

Specifies the number of replicas of this media server. Minimum number of supported replicas is 1.

tag: 10.0.0.1-special

To use a different image tag specifically for the media servers, uncomment this value and provide the desired tag. This overrides the tag specified above in the common table.

nodeSelector:

labelKey: kubernetes.io/os

labelValue: linux

Specify a key and value that identifies nodes where media-server pods will run.

data:

capacity: 50Gi

storageClassName: managed-premium-nbux

This storage applies to the media server data volumes.

The minimum data size for a media server is 50 Gi.

log

capacity: 30Gi

storageClassName: managed-premium-nbux

This storage applies to the media server log volumes.

Log volumes must be at least 30Gi.

networkLoadBalancer:

annotations: - service.beta.kubernetes.io/ azure-load-balancer -internal-subnet: example-subnet

ipList:

ipAddr: 4.3.2.2

fqdn: media1-1.example.com

ipAddr: 4.3.2.3

fqdn: media1-2.example.com

Uncomment annotations to specify additional media-server specific annotations. These values are merged with the values given in the loadBalancerAnnotations. The duplicate values given here, override the corresponding values in the loadBalancerAnnotations.

The number of entries in the IP list should match the replica count specified above.

licenseKeys:

Uncomment annotations to specify any license key that is specifically applicable to the media server(s).

msdpScaleouts:

- resourceNamePrefix: dedupe1

This specifies MSDP Scaleout configurations. This is given as a list, but it would be rare to need more than one scaleout deployment in a single environment. Use the `replicas` property below to scale out. It's also possible to have zero MSDP scaleouts; in that case, either remove the msdpScaleouts section entirely, or define it to an empty list: msdpScaleouts: []

tag: '16.0.1'

This tag overrides the one defined in the table 1-3. It is necessary because the MSDP Scaleout images are shipped with tags different from the NetBackup primary and media images.

replicas: 4

This is the scaleout size of this MSDP Scaleout component. It is a required value, and it must be between 4 and 16 inclusive.

serviceIPFQDNs:

ipAddr: 1.2.3.4

fqdn: dedupe1-1.example.com

ipAddr: 1.2.3.5

fqdn: dedupe1-2.example.com

ipAddr: 1.2.3.6

fqdn: dedupe1-3.example.com

ipAddr: 1.2.3.7

fqdn: dedupe1-4.example.com

These are the IP addresses and host names of the MSDP Scaleout servers. The number of the entries should match the number of the replicas specified above.

kms:

keyGroup: example-key-group

Specifies the initial key group and key secret to be used for KMS encryption. When reusing storage from a previous deployment, the key group and key secret may already exist. In this case, provide the keyGroup only.

keySecret:

example-key-secret

Specify keySecret only if the key group does not already exist and needs to be created. The secret type should be Opaque, and you can create the secret either using a YAML or the following command:

kubectl create secret generic example-key-secret --namespace nb-namespace --from-literal=username="devuser" --from-literal=passphrase="test passphrase"

loadBalancerAnnotations:

service.beta.kubernetes .io/azure-load- balancer-internal: true

For MSDP scaleouts, the default value for the Azure-load-balancer-internal annotation is `false`, which may cause the MSDP Scaleout services in this Environment to be accessible publicly. To make sure that they use private IP addresses, specify `true` here or in the loadBalancerAnnotations above in Table 1-3.

credential:

secretName: msdp-secret1

This defines the credentials for the MSDP Scaleout server. It refers to a secret in the same namespace as this environment resource. Secret can be either of type 'Basic-auth' or 'Opaque'. You can create secrets using a YAML or by using the following command:kubectl create secret generic <msdp-secret1> --namespace <nb-namespace> --from-literal=username=<"devuser"> --from-literal=password=<"Y@123abCdEf">

autoDelete: false

Optional parameter. Default value is true. When set to true, the MSDP Scaleout operator deletes the MSDP secret after using it. In such case, the MSDP and primary secrets must be distinct. To use the same secret for both MSDP scaleouts and the primary server, set autoDelete to false.

catalog:

capacity: 1Gi

storageClassName: standard

This storage applies to MSDP Scaleout to store the catalog and metadata. The catalog size may only be increased for capacity expansion. Expanding the existing catalog volumes cause short downtime of the engines. Recommended size is 1/100 of backend data capacity.

dataVolumes:

capacity: 5Gi

storageClassName: standard

This specifies the data storage for this MSDP Scaleout resource. You may increase the size of a volume or add more volumes to the end of the list, but do not remove or re-order volumes. Maximum 16 volumes are allowed. Appending new data volumes or expanding existing ones will cause short downtime of the Engines. Recommended volume size is 5Gi-32Ti.

log:

capacity: 20Gi

storageClassName: standard

Specifies log volume size used to provision Persistent Volume Claim for Controller and MDS Pods. In most cases, 5-10 Gi capacity should be big enough for one MDS or Controller Pod to use.

nodeSelector:

labelKey: kubernetes.io/os

labelValue: linux

Specify a key and value that identifies nodes where MSDP Scaleout pods will run.

resourceNamePrefix

Specifies the prefix name for the primary, media, and MSDP Scaleout server resources.

ipAddr, fqdn and

loadBalancerAnnotations

The values against ipAddr, fqdn and loadBalancerAnnotations against following fields should not be changed post initial deployment. This is applicable for primary, media, and MSDP Scaleout servers. For example:

- The loadBalancerAnnotations for loadBalancerAnnotations: service.beta.kubernetes.io/azure-load-balancer -internal-subnet: example-subnet service.beta.kubernetes.io/azure-load-balancer -internal: 'true'

- The IP and FQDNs values defined for Primary, Media and MSDPScaleout  ipList:    - ipAddr: 4.3.2.1      fqdn: primary.example.com   ipList:    - ipAddr: 4.3.2.2      fqdn: media1-1.example.com    - ipAddr: 4.3.2.3      fqdn: media1-2.example.com   serviceIPFQDNs:    - ipAddr: 1.2.3.4      fqdn: dedupe1-1.example.com    - ipAddr: 1.2.3.5      fqdn: dedupe1-2.example.com    - ipAddr: 1.2.3.6      fqdn: dedupe1-3.example.com    - ipAddr: 1.2.3.7      fqdn: dedupe1-4.example.com
