An IBM Cloud Schematics template to provision a Kubernetes cluster with N worker nodes in IBM Cloud. Schematics uses Terraform as the infrastructure as code engine. With this template, you can provision and manage infrastructure as a single unit.
See the IBM Cloud docs for more information about Schematics and the IBM Cloud Container Service.
Environments can be used to separate software components into development tiers (e.g. staging, QA, and production).
- In IBM Cloud, go to the menu and select the Schematics dashboard.
- In the left navigation menu, select Templates to access the template catalog.
- Click Create on the containers cluster template. You are taken to a configuration page where you can define data about your environment.
- Define values for your variables according to the following table.
| Variable Name | Description | Default Value |
|---|---|---|
| bluemix_api_key | Your IBM Cloud API key. You can get the value by running bx iam api-key-create <key name>. |
|
| cluster_name | The base name for the cluster. | kubecluster |
| datacenter | The data center for the cluster, You can get the list with by running bluemix cs locations. |
dal12 |
| machine_type | The CPU cores, memory, network, and speed. You can get a list for a given location by running bluemix cs machine-types <location>. |
u1c.2x4 |
| num_workers | The number of worker nodes in the cluster. | 2 |
| org | Your IBM Cloud org name. | |
| private_vlan_id | The private VLAN for your account. You can run bx cs vlans <location>. |
|
| public_vlan_id | The public VLAN for your account. You can run bx cs vlans <location>. |
|
| region | The IBM Cloud region where you want to deploy your cluster. | us-south |
| space | Your IBM Cloud space name. | dev |
| subnet_id | The portable subnet to use for cluster. You can view a list of available subnets by running bx cs subnets. |
NOTE: The num_workers variable has to be a value between 1 and 10. All worker nodes in the cluster are assigned the name 'worker-N'. It is not possible to change the base name of worker nodes with this template.
After setting up your environment with this template, you can run Plan to preview how Schematics will deploy resources (in this case, a Kubernetes cluster) to your environment. When you are ready to deploy the cluster, run Apply.
