5.2 Argo CD

As usual, there are multiple ways to find out what Argo CD’s dashboard URL is:

• OpenShift exposes the link via its web console:

• Or get it via route from the openshift-gitops namespace:

oc -n openshift-gitops get routes

• On the upper right corner, click on the + icon and then choose New Repository:

• On the New Repository page, choose a name such as “argocd-gitops-test”
• Choose the repo’s visibility
• On the bottom of the page, click on the Create Repository button

First, make sure you are in the Applications view, then click on + NEW APP:

Now fill in the appropriate information:

• GENERAL
  • Application Name: anything of your choosing
  • Project: default
  • Leave the rest as-is
• SOURCE
  • Repository URL: The URL to your Git repository
  • Path: Indicate in what folder the resource files reside; leave empty if they are in the root folder
  • Leave the rest as-is
• DESTINATION
  • Cluster URL: https://kubernetes.default.svc
  • Namespace: Leave empty

• Create a new directory for your repository files:

mkdir cluster-configs
cd cluster-configs

• Initialize it for usage with Git:

git init
git remote add origin <your git repository's URL>
git push -u origin main

• Taking the KubeletConfig from task 1.3.1 as an example, save its definition as a new file inside the Git directory and push it to your Gitea repository:

wget https://raw.githubusercontent.com/acend/openshift-operations-training/main/content/en/docs/01/resources/kubeletconfig_master.yaml
git add kubeletconfig_master.yaml
git commit -m "Add master's kubelet configuration"
git push
