But... Will it actually work?
To test it out we will let ArgoCD upgrate itself! The installed version is v2.0.5 but v2.1.0 is out... let's upgrade!
Have a look at the argocd_deploy/kustomization.yaml file... Can you figure out how to do it?
Apply the change by committing and pushing to master, no need to use the docker command line anymore.
After a couple of minutes you should see the new version deployed!
If the waiting is too long, you can force Argo to refresh the definition
manually by opening the web interface and pressing the Refresh button
under the argocd application.
It is possible for Argo to receive webhook from Github whenever a new commit is pushed (docs). However its configuration is more complex and out of scope for this workshop. When webhooks are not configured, Argo will poll regularly the git repo.
If you have done every step correctly, you should see v2.1.0 in the top
left corner of the web interface, below Argo's logo.
