Prerequisites

Each module in this workshop depends on work performed in previous modules. This section lays out the work that is required from previous modules in case you need to advance for some reason such as not being able to complete a module due to time, technical difficulties or the instructor running a shortened version of the workshop.

Module 1 - OpenShift as an Application Platform

In this module participants learn how to use the OpenShift console and command line to deploy applications. The work performed here to login into OpenShift and clone the workshop git repository is required in all following modules.

  • Access the OpenShift console here:

{openshift_console_url}

  • Login into the console using the Keycloak provider:

openshift login
If you accidentally login with the htpasswd_provider option then you will not be able to login to OpenShift with Keycloak. Please ask your instructor to correct it by deleting the OpenShift user and identity before logging in again with Keycloak.

  • Use the username {user} and password openshift

  • In OpenShift Console you will need to click on your user name in the upper right corner and select Copy login command:

oc login command

  • Paste the command into the terminal to login into OpenShift.

git clone -b main --single-branch https://gitea-gitea.{subdomain}/user1/workshop ~/workshop

  • Deploy the Pipeline that will be required to build the front-end image in Module 4

sed 's/$USER/{user}/' ~/workshop/content/modules/ROOT/examples/pipeline-helm-app.yaml | sed 's/$SUBDOMAIN/{subdomain}/' | oc create -f - -n {user}-argocd
