= ocp4-workload-tektoncd-foundations - Tekton Foundations 

== Role overview

* This role is used to prepare an environment for working through the foundations of link:https://tekton.dev[Tekton]. 
** Playbook: link:./tasks/pre_workload.yml[pre_workload.yml] - Sets up an
 environment for the workload deployment
*** Debug task will print out: `pre_workload Tasks completed successfully.`

** Playbook: link:./tasks/workload.yml[workload.yml] - Used to deploy the actual
 workload, i.e, 3scale, Mobile or some Demo
*** This role only prints the current username for which this role is provisioning.
*** Debug task will print out: `workload Tasks completed successfully.`

** Playbook: link:./tasks/post_workload.yml[post_workload.yml] - Used to
 configure the workload after deployment
*** This role doesn't do anything here
*** Debug task will print out: `post_workload Tasks completed successfully.`

** Playbook: link:./tasks/remove_workload.yml[remove_workload.yml] - Used to
 delete the workload
*** This role doesn't do anything here
*** Debug task will print out: `remove_workload Tasks completed successfully.`

== Review the defaults variable file

* This file link:./defaults/main.yml[./defaults/main.yml] contains all the variables you need to define to control the deployment of your workload.
* The variable *ocp_username* is mandatory to assign the workload to the correct OpenShift user.
* A variable *silent=True* can be passed to suppress debug messages.
* You can modify any of these default values by adding `-e "variable_name=variable_value"` to the command line
