To run an example customisation you need an exiting OpenShift cluster with integreatly installed.
Next you need to get the available inventory file from the manifest secret
(mac osx)
oc get secret inventory -n webapp --template '{{index .data "generated_inventory"}}' | base64 -D > inventory
(Linux)
oc get secret inventory -n webapp --template '{{index .data "generated_inventory"}}' | base64 -d > inventory
You should also be logged into the cluster as an admin user.
You can then run the example playbook using ansible-playbook
ansible-playbook -i inventory playbooks/add_custom_che_stack.yaml
