Scripts to deploy AWS OCP cluster + GPFS

Installation

Here are the steps to deploy OCP + GPFS. These steps will create an OCP cluster with 3 master + 3 workers by default and then will create a multiattach EBS volume and attach it to the three workers.

1. Make sure you have the right ansible dependencies via ansible-galaxy collection install -r requirements.yml and also that you have the httpd tools installed (httpd-tools on Fedora or brew install httpd on MacOSX)
2. Make sure your aws credentials and aws cli are in place and working
3. Make sure you have redhat tokens which enable downloads, token can be obtained at https://console.redhat.com/openshift/downloads
4. Copy the token to ~/.pullsecret.json. The file should be in the following format:

{
  "auths": {
    "cloud.openshift.com": {
      "auth": "YOUR_TOKEN_HERE",
      "email": "[email protected]"
    },
    "quay.io": {
      "auth": "YOUR_TOKEN_HERE",
      "email": "[email protected]"
    },
    "registry.redhat.io": {
      "auth": "YOUR_TOKEN_HERE",
      "email": "[email protected]"
    }
  }
}

5. Run the following to create an overrides.yml.

cat > overrides.yml<<EOF
# ocp_domain: "fusionaccess.devcluster.openshift.com"
ocp_cluster_name: "gpfs-bandini"
gpfs_volume_name: "bandini-volume"
# ocp_worker_count: 3
# ocp_worker_type: "m5.2xlarge"
# ocp_master_count: 3
# ocp_master_type: "m5.2xlarge"
# ocp_az: "eu-central-1a"
# ocp_region: "eu-central-1"

# gpfs_version: "v5.2.2.x"
# ssh_pubkey: "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIO8CumOo7uGDhSG5gzRdMkej/dBZ3YhhpKweKeyW+iCK michele@oshie"
EOF

Change it by uncommenting and tweaking at least the following lines.

• ocp_domain
• ocp_cluster_name
• gpfs_volume_name
• ocp_az
• ocp_region

6. Make sure you read group_vars/all and have all the files with the secret material done.

7. Run make ocp-clients. This will download the needed oc and openshift-install version in your home folder under ~/aws-gpfs-playground/<ocp_version>. You might need to add this path to your bash PATH or copy it to the /usr/bin folder.

8. Run make install to install the openshift-fusion-access operator

9. Once the installation is complete, you can retrieve the cluster access information from the installation log file located at: ~/aws-gpfs-playground/ocp_install_files/.openshift_install.log

Look for the section in the log after the "Install complete!" message. The log will contain the following key details:

• KUBECONFIG File Path: The path for the Kube Config file.
• OpenShift web-console: The URL for the OpenShift web console in AWS.
• Login Credentials: The username and password to log in to the web console.

Deletion

To delete the cluster and the EBS volume, run make destroy

Health Check

Run make gpfs-health to run some GPFS healthcheck commands

Delete GPFS objects

Run make gpfs-cleanup to remove all the gpfs objects we know about
