Deploy the cluster
Deploy the cluster#
rosa CLI to create the ROSA cluster.
Note: If you want to see all available options for your cluster run
rosa create cluster --helpor for interactive mode you can run
rosa create cluster --interactive
Run the following command to create a cluster with all the default options
rosa create cluster --cluster-name=<cluster name>
rosa create cluster --cluster-name=my-rosa-cluster
You should see a response like the following:
I: Creating cluster 'my-rosa-cluster' I: To view a list of clusters and their status, run 'rosa list clusters' I: Cluster 'my-rosa-cluster' has been created. I: Once the cluster is installed you will need to add an Identity Provider before you can login into the cluster. See 'rosa create idp --help' for more information. I: To determine when your cluster is Ready, run 'rosa describe cluster -c my-rosa-cluster'. I: To watch your cluster installation logs, run 'rosa logs install -c my-rosa-cluster --watch'. Name: my-rosa-cluster DNS: my-rosa-cluster.abcd.p1.openshiftapps.com ID: 1idb8u7qc0jinctmmf0000000000000 External ID: AWS Account: 000000000000 API URL: Console URL: Nodes: Master: 3, Infra: 2, Compute: 2 Region: us-east-1 State: pending (Preparing account) Channel Group: stable Private: No Created: Jan 24 2021 05:15:37 UTC Details Page: https://cloud.redhat.com/openshift/details/1idb8u7qc0jinctmmf0000000000000
This will take about 30-40 minutes to run.
The default settings are as follows:
- 3 Master Nodes, 2 Infra Nodes, 2 Worker Nodes
- Worker node type: m5.xlarge
- Region: As configured for the AWS CLI
- The most recent version of OpenShift available to
- A single availability zone
- Public cluster (Public API)
You can run the following command to check the status of the cluster
rosa describe cluster --cluster=my-rosa-cluster
You should notice the state change from “pending” to “installing”.
Once the state has changed to “ready” your cluster is now installed.
rosa list clustersto see a list of all available clusters. You should see the one just created.
In the next step we will create an admin user to be able to use the cluster immediately.
