Chain: ipi-aws-pre-workers-rhel

The worker RHEL setup step contains all steps that add RHEL workers to an existing cluster


Name Description
ipi-aws-pre The IPI setup step contains all steps that provision an OpenShift cluster with a default configuration on AWS.
ssh-bastion The post-installation ssh-bastion step adds an ssh bastion to an exiting cluster.
workers-rhel-aws-provision The post-installation provision step creates new machinesets which provision new RHEL instances for worker nodes.
workers-rhel The workers rhel step chain contains steps necessary to prepare and configure OCP on RHEL worker hosts.

In addition to the default environment, the following variables are consumed through this chain

Variable Name Variable Content Consumed By Steps
BASE_DOMAIN A fully-qualified domain or subdomain name. The base domain of the cloud provider is used for setting baseDomain variable of the install configuration of the cluster. (default: ipi-conf-aws
COMPUTE_NODE_TYPE The instance type to use for compute nodes (e.g. AWS We use a 4 core worker to match the median configuration of the fleet. (default: m5.xlarge) ipi-conf-aws
FIPS_ENABLED (default: false) ipi-conf
OPENSHIFT_INSTALL_EXPERIMENTAL_DUAL_STACK Using experimental Azure dual-stack support (default: false) ipi-install-install
OPENSHIFT_INSTALL_PRESERVE_BOOTSTRAP Keep bootstrap resources after install. Warning: this should only be used for debugging purposes, and poses a risk to cluster stability. ipi-install-install
PLATFORM_VERSION workers-rhel-aws-provision workers-rhel-repos
SIZE_VARIANT The size of the cluster in one of our supported t-shirt values that is standard across all CI environments. The sizes are: * "" (default) - 4 vCPU, 16GB control plane nodes, default workers * "compact" - 8 vCPU, 32GB control plane nodes, no workers * "large" - 16 vCPU, 64GB+ control plane nodes, default workers, suitable for clusters up to 250 nodes * "xlarge" - 32 vCPU, 128GB+ control plane nodes, default workers, suitable for clusters up to 1000 nodes These sizes are roughly consistent across all cloud providers, but we may not be able to instantiate some sizes in some regions or accounts due to quota issues. ipi-conf-aws
ZONES_COUNT The number of Availability Zones to present in the cluster. This depends on the selected region. (default: 2) ipi-conf-aws
