OpenShift 4 IPI Alibaba Install Documentation

The OpenShift 4 IPI Alibaba variable file can be found at OCP-4.X/vars/install-on-alibaba.yml. It will configure the deployment playbook at OCP-4.X/deploy-cluster.yml to perform a cluster installation on Alibaba. In addition to installing a cluster, the playbook can also perform day 2 operations to include deploying three infra nodes and deploying a workload node to isolate workload driver pods from openshift-scale/workloads repo.

Usage

Running from the CLI:

$ cp OCP-4.X/inventory.example inventory
$ # Edit inventory and add your expected orchestration host
$ # Edit deployment variables (Ex vi OCP-4.X/vars/install-on-alibaba.yml) or define env variables
$ ansible-playbook -v -i inventory OCP-4.X/deploy-cluster.yml -e platform=alibaba
