scale-ci-ansible

The repo contains playbooks for scale-ci automation tasks. Those include install, scaling, upgrade, and post install configuration. The environments under test include RHCOS based OCP on AWS and OCP3 on OSP installs.

RHCOS based OCP 4.X Usage

The playbooks focus on RHCOS based OCP on AWS at this time and are found in the OCP-4.X directory.

The prerequisites are simply an orchestration machine with kubeconfig and oc command. The orchestration host can be localhost if properly setup.

Prepare the Jump host

Run

Clone the github repo:

$ git clone https://github.com/redhat-performance/scale-ci-ansible.git
$ cd scale-ci-ansible
$ cp OCP-4.X/inventory.example inventory

Set the variables including AWS credentials, Install config, post-install and kick off the playbook:

$ ansible-playbook -vv -i inventory OCP-4.X/install.yml

Set OPENSHIFT_POST_INSTALL and OPENSHIFT_TOOLING to true to run the post-install and post-config options to configure the cluster to be able to run perf and scale tests using Scale-CI pipeline. The varibles under the post-install section of the inventory can be modified to override the default values.

Cleanup

Set OPENSHIFT_INSTALL, OPENSHIFT_POST_INSTALL, OPENSHIFT_TOOLING to False and OPENSHIFT_AWS_INSTALL_CLEANUP to True in the inventory and run the playbook:

$ ansible-playbook -vv -i inventory OCP-4.X/install.yml

RHCOS scale

The RHCOS scale playbook is OCP-4.X/scale.yml and can scale an existing RHCOS cluster.

Running from CLI:

$ cp OCP-4.X/inventory.example inventory
$ # Add orchestration host to inventory
$ # Edit vars in OCP-4.X/vars/scale.yml or define Environment vars (See below)
$ time ansible-playbook -vv -i inventory OCP-4.X/scale.yml
