Manage GKE infrastructure

A GKE blueprint contains custom resources you can combineto specify the intent to deploy a GKE cluster. The following list definesthe role of each custom resource:

  • ContainerCluster: creates a private GKE cluster with aprovisioned service mesh.
  • ClusterInit: initializes the cluster's lifecycle that Telecom Network Automation(Telecom Network Automation) manages. This lifecycle includes installingTelecom Network Automation components on the GKE cluster.
  • SourceRepoRepository andRepository: sets up the GitOps pipeline forthe created GKE cluster using Cloud Source Repository and Porch alongwith ConfigSync, installed from the previous resource.
  • ContainerNodePool: creates a node pool with Ubuntu OS, SSD disk typeande2-standard-2 machine type as default. You can edit these details.

When creating a deployment, you can customize the blueprint using followingparameters in thesetters.yaml file:

ParameterDescription
project-idThe project id of the currentproject.
project-numThe project number of the currentproject.
cluster-nameThe name of the GKE cluster.
locationThe compute location of the cluster
master-ip-rangeThe IP CIDR block thatGKE main nodesuse
cluster-ipv4-cidr-blocksThe IP CIDR block that pods use.
services-ipv4-cidr-blocksThe IP CIDR block that servicesuse.
compute-network-nameThe name of the compute network.Change this name if you don'tintend to use a VPC where anOrchestration cluster is createdfor the GKE cluster.
clients-ipv4-cidr-blocksThe IP CIDR block for clients thataccess the cluster
node-countThe number of nodes in the nodepool per zone. If a regionalcluster is created, the number ofnodes in the node pool increases tothree times the original amount.
nodepool-nameThe name of the node pool.
node-machine-typeThe type of the node machine.

GKE blueprints

Create a GKE blueprint

  1. From the navigation menu, clickBlueprints.
  2. From the drop-down menu, select your preferred Orchestration cluster.
  3. ClickImport from Library.
  4. SelectGKE Cluster blueprint.
  5. ClickAdd Blueprint.
  6. On the next page, specify a name for the blueprint.
    1. Optionally, add any labels you need.
  7. ClickCreate. Your blueprint appears in theDraft Blueprints list.

Edit a blueprint

  1. From the navigation menu, clickBlueprints > Drafts Blueprint.
  2. Select your preferred blueprint. A blueprint editor appears.
  3. Edit thecluster.yaml andnodepool.yaml files.

  4. Afterwards, clickSave File.

    Note: You must save each file individually.

Propose a blueprint

  1. From the navigation menu, clickBlueprints > Drafts Blueprint.
  2. Select your preferred blueprint. A blueprint editor appears.
  3. ClickPropose. The status of the blueprint updates toProposed.

Approve a blueprint

  1. From the navigation menu, clickBlueprints.
  2. Click theAction icon on your preferred blueprint.
  3. SelectApprove. The blueprint appears inApproved Blueprints.

GKE deployment

Create a GKE Deployment

  1. From the navigation menu, clickBlueprints > Approved Blueprints.
  2. Click the GKE blueprint you want to deploy.
  3. ClickCreate Deployment.
  4. Provide a name for the deployment.
  5. ClickCreate Deployment. The deployment appears inDraftDeployment.

Edit a GKE deployment

  1. From the navigation menu, clickBlueprints.
  2. Select the GKE deployment you want to edit. Adeployment editor appears.
  3. Edit thesetters.yaml file.
  4. Afterwards, clickSave File.

Apply a GKE deployment

  1. From the navigation menu, clickBlueprints.
  2. Select the name of the GKE deployment you want toapply. A deployment editor appears.
  3. ClickDeploy. A confirmation dialog appears.
  4. Confirm the deployment by clickingDeploy. The deployment appears inApplied Deployment.
Note: The GKE cluster name must be less than 15 characters, and have aunique cluster name for each blueprint deployment. Deleting aGKE blueprint deployment does not* *make the cluster namereusable.

Delete a GKE cluster

  1. From the navigation menu, clickDeployments > Applied Deployments.
  2. Select the GKE deployment you want to delete.
  3. ClickDelete.
  4. Confirm the deletion of the deployment.
