openshift-cli-installer 3.0.0

CLI to install/uninstall Openshift clusters.

openshift-cli-installer

Basic Openshift install CLI wrapper.
The tool allows deploying or deletion of one or more clusters.
The clusters can be deployed on different platforms; currently supported platforms: AWS IPI, AWS OSD, GCP OSD, ROSA and Hypershift.
Each cluster can be provided with different configuration options, such as worker type, number of workers etc.

Tools

• AWS IPI installation uses openshift-installer cli which is extracted from the cluster's target version.
  The binary is taken from quay.io/openshift-release-dev/ocp-release:<target version>
• ROSA and Hypershift installation uses the latest ROSA CLI

Container

Image locate at openshift-cli-installer
To pull the image: podman pull quay.io/redhat_msi/openshift-cli-installer

Command line

Install inside poetry venv:

poetry install
poetry run python openshift_cli_installer/cli.py --help

Install as system cli:

pipx install .

For shell complition Add this to ~/.bashrc or ~/.zshrc:

eval "$(_OPENSHIFT_CLI_INSTALLER_COMPLETE=zsh_source openshift-cli-installer)"

Create clusters from YAML file

User can create/destroy clusters by sending YAML file instead with CLI args Example YAML file can be found here pass --clusters-yaml-config-file=.local/clusters-example.yaml to use YAML file. Action also can be passed to the CLI as --action create/destroy instead of specifying the action in the YAML file. --action create --clusters-yaml-config-file=.local/clusters-example.yaml

Global CLI configuration

• --clusters-install-data-directory: Clusters configurations are written to <clusters-install-data-directory><platform><cluster name>; write permissions are needed.

  • <cluster directory>/auth contains kubeconfig and kubeadmin-password files
  • Hypershift cluster:
    • <cluster directory>/auth/api.login contains the full login command to the cluster.
    • <cluster directory>/auth/rosa-admin-password contains the password for the rosa-admin user.

• --parallel: To create / destroy clusters in parallel

• Pass --s3-bucket-name (and optionally --s3-bucket-path and --s3-bucket-object-name) to back up in an S3 bucket.

• --ocm-token: OCM token, defaults to OCM_TOKEN environment variable.

• --must-gather-output-dir: Path to must-gather output dir. must-gather will try to collect data when cluster installation fails and cluster can be accessed.

• AWS IPI clusters:

  • The installer output is saved in the <cluster directory>.
  • The data is used for cluster destroy.
  • platform=aws: Must pass in cluster parameters
  • base-domain: cluster parameter is mandatory
  • auto-region=True: Optional cluster parameter for assigning region param to a region which have the least number of VPCs.
  • log_level: Log level, defaults to error for cluster config to hide the openshift-installer logs which contains kubeadmin password.
  • --registry-config-file: registry-config json file path, can be obtained from openshift local cluster
  • --docker-config-file: Path to Docker config.json file, defaults to ~/.docker/config.json. File must include token for registry.ci.openshift.org
  • --ssh-key-file: id_rsa file path, defaults to /openshift-cli-installer/ssh-key/id_rsa.pub

  • The data is used for cluster destroy.
  • platform=gcp: Must pass in cluster parameters
  • base-domain: cluster parameter is mandatory
  • --gcp-service-account-file: Path to GCP service account json. The file will be copied to specific path ~/.gcp/osServiceAccount.json for installer . Follow these steps to get the ServiceAccount file.
  • --registry-config-file: registry-config json file path, can be obtained from openshift local cluster
  • --docker-config-file: Path to Docker config.json file, defaults to ~/.docker/config.json. File must include token for registry.ci.openshift.org

  • --aws-access-key-id: AWS access key ID
  • --aws-secret-access-key: AWS secret access key
  • --aws-account-id: AWS account ID

• GCP OSD clusters:

  • platform=gcp-osd: Must pass in cluster parameters
  • --gcp-service-account-file: Path to GCP service account json. Follow these steps to get the ServiceAccount file.

Cluster parameters

Every call to the openshift installer cli must have at least one --cluster option.

• Mandatory parameters:
  • name or name-prefix: The name of the cluster or the prefix of the name of the cluster, if prefix is used we generate a unique name up to 15 characters.
  • platform: The platform to deploy the cluster on (supported platforms are: aws, rosa and hypershift)
  • region: The region to deploy the cluster. Optional for AWS-IPI and AWS-OSD clusters, but mandatory for other (GCP, ROSA, Hypershift) clusters.
• Optional parameters:
  • Parameter names should be separated by semicolons (;)
  • To set cluster create / destroy timeout (not applicable for AWS IPI clusters), pass --cluster ...timeout=1h'; default is 60 minutes.
  • timeout and expiration-time format examples: 1h, 30m, 3600s
  • ocm-env: OCM environment to deploy the cluster; available options: stage or production (defaults to stage). AWS-IPI clusters only use production.
  • AWS/GCP IPI:
    • To overwrite cluster config, check below manifests for parameters
      • aws-install-config-template.j2
      • gcp-install-config-template.j2
    • Every parameter (marked with double curly brackets in the template) can be overwritten.
    • For example: to overwrite {{ fips|default("false", true) }} pass --cluster '...fips=true'
  • ROSA / Hypershift:
    • Every supported ROSA CLI create/delete parameter can be passed. Check rosa create --help for more details.
    • For example:
      • Pass --cluster ...fips=true' to enable FIPS
      • Pass --cluster ...expiration-time=2h' to have the cluster expiration time set to 2 hours
  • Hypershift:
    • Cluster VPC CIDR, public and private subnets can be configured from the CLI. Otherwise, values in setup-vpc.tf will be used.
      • To set cidr, pass --cluster ...cidr=1.1.0.0/16'
      • To set private-subnets, pass --cluster ...private-subnets=10.1.1.0/24,10.1.2.0/24'
      • To set public-subnets, pass --cluster ...public-subnets=10.1.10.0/24,10.1.20.0/24'

Steps to create GCP Service Account File

To create the file, create a service account and download it:

1. Go to https://console.cloud.google.com/iam-admin/serviceaccounts?project=
2. Select the service account -> "Create Key"
3. Select the Key Type as JSON and click Create

ACM (Advanced Cluster Management)

Managed clusters (Rosa, AWS and OSD) can be deployed with ACM and attached to ACM hub. To deploy ACM on cluster pass --cluster ... acm=True To enable observability on the ACM enabled cluster pass --cluster ... acm-observability=True Attach clusters to ACM cluster hub:

• Support only clusters that created during the run
• To attach cluster to this ACM hub pass --cluster ... acm-clusters=mycluser1,mycluster2
  • mycluser1,mycluster2 needs to be sent with --cluster ... for the script to create them.

Destroy clusters

--destroy-clusters-from-install-data-directory, --destroy-clusters-from-s3-bucket and --destroy-clusters-from-install-data-directory-using-s3-bucket must have:

  --ocm-token=$OCM_TOKEN \
