| 805b3d | 1 | = ocp4-workload-quarkus-workshop - Deploy Quarkus Workshop into OCP4 |
| JF | 2 | |
| 3 | == Role overview | |
| 4 | ||
| 5 | * This role deploys logging into an OpenShift 4 Cluster. It depends on infrastructure nodes existing. It consists of the following playbooks: | |
| 6 | ** Playbook: link:./tasks/pre_workload.yml[pre_workload.yml] - Sets up an | |
| 7 | environment for the workload deployment. | |
| 8 | *** Debug task will print out: `pre_workload Tasks completed successfully.` | |
| 9 | ||
| 10 | ** Playbook: link:./tasks/workload.yml[workload.yml] - Used to deploy logging | |
| 11 | *** Debug task will print out: `workload Tasks completed successfully.` | |
| 12 | ||
| 13 | ** Playbook: link:./tasks/post_workload.yml[post_workload.yml] - Used to | |
| 14 | configure the workload after deployment | |
| 15 | *** This role doesn't do anything here | |
| 16 | *** Debug task will print out: `post_workload Tasks completed successfully.` | |
| 17 | ||
| 18 | ** Playbook: link:./tasks/remove_workload.yml[remove_workload.yml] - Used to | |
| 19 | delete the workload | |
| 20 | *** This role removes the logging deployment and project but not the operator configs | |
| 21 | *** Debug task will print out: `remove_workload Tasks completed successfully.` | |
| 22 | ||
| 23 | == Review the defaults variable file | |
| 24 | ||
| 25 | * This file link:./defaults/main.yml[./defaults/main.yml] contains all the variables you need to define to control the deployment of your workload. | |
| 26 | * The variable *ocp_username* is mandatory to assign the workload to the correct OpenShift user. | |
| 27 | * A variable *silent=True* can be passed to suppress debug messages. | |
| 28 | * You can modify any of these default values by adding `-e "variable_name=variable_value"` to the command line | |

| 81 | === Deploy Workload on OpenShift Cluster from an existing playbook: | |
| 82 | ||
| 83 | [source,yaml] | |
| 84 | ---- | |
| 85 | - name: Deploy a workload role on a master host | |
| 86 | hosts: all | |
| 87 | become: true | |
| 88 | gather_facts: False | |
| 89 | tags: | |
| 90 | - step007 | |
| 91 | roles: | |
| 92 | - { role: "{{ocp_workload}}", when: 'ocp_workload is defined' } | |
| 93 | ---- | |
| 94 | NOTE: You might want to change `hosts: all` to fit your requirements | |
| 95 | ||
| 96 | ||
| 97 | === Set up your Ansible inventory file | |
| 98 | ||
| 99 | * You can create an Ansible inventory file to define your connection method to your host (Master/Bastion with `oc` command) | |
| 100 | * You can also use the command line to define the hosts directly if your `ssh` configuration is set to connect to the host correctly | |
| 101 | * You can also use the command line to use localhost or if your cluster is already authenticated and configured in your `oc` configuration | |
