[@fabmartel]

very nice. Im from Belgium, i speak french, but i have all understand ;-) I'm interested in a video showing ArgoCD - GitLab not deploying a web app, but an Apache Camel-K integration. Would it be possible for you to make one? I think you will have the right reflexes directly on ArgoCD. The Kustomize version is really interesting, especially when you don't want to create the entire helm ecosystem. THANKS

After performing the port forwarding, while trying to browse the url i am having issue as "unable to connect"

[@sonnygarcia607]

@DevOpsJourney Why wouldn't you just use a `checksum` annotation inside of your Helm deployment that digests the contents of the ConfigMap? When the contents of the ConfigMap changes, it changes the Deployment triggering a rolling update of the pods? Does ArgoCD do something different than stock Helm + K8s?

[@tejit2004]

Hi, at 10:37, you are saying one argocd installation can manage multiple kubernates cluster, but i don't understand how? because argocd is going to be installed in a specific cluster, so is there not one-to-one relationship between argocd and K8S cluster, if not how you can manage multiple K8S cluster?

[@DevOpsJourney]

There is a clusters tab. You can add other clusters into ArgoCD there. ArgoCD will just need credentials and a URI for connecting/managing other clusters

[@anas6435]

I noticed that you are using an animated moving background which is really cool .. How do you create those?

[@DevOpsJourney]

I use Davinci Resolve, chose a gradient color then added icons and animated them in Fusion

[@gozh2002]

if it is helm chart and deployed by argocd, would I still able to use helm CLI to rollback and list etc? or I have to use argocd CLI then?

[@DevOpsJourney]

Use the argocli

[@semspiri789]

There is an old tool to handle configmap changes, called stakater/Reloader

[@kazwalker764]

Around 25:00, when using Helm, you should use a checksum annotation of the config map in the deployment. Google "helm tricks automatically roll deployments", it'll be the first result from the Helm docs. Great video, cheers!

[@MuhammadKamranAzeem]

Thanks for the video, but apparently the most important piece is missing. When the actual application code changes, how do you build a new image (with a new tag other than "latest"? and how do you update the helm and kustomize configurations with that new image name:tag, and how do you trigger anrgo CD that application code has been changed, new image has been created and it (argo cd) should kick off and deploy the newest version? In your video you only showed what happens when the configuration part changes. So it is incomplete IMHO.

[@DevOpsJourney]

Thanks for the comment. I briefly mention this at 1:35. You would have two repositories, one for the image and one for the configuration. The CI/CD for the first repository would work like any other container pipeline, but at the end it would submit a PR to your config repository to update it with the new image tag. I didn't work it into the practical portion of the video because I didn't want to overcomplicate things I just wanted to show the basics of ArgoCD. Most people when getting started with ArgoCD update the configuration repository manually with the new image tag. I hope that makes sense. Thanks again for your feedback - I was thinking of doing a video of a complete Gitops flow that does exactly what you mentioned and your comment has inspired me to do that, so check back in a month or so :)

I'm trying to deploy this on an M series mac, how can I specify the architecture of the nodes? I'm looking at the values.yaml file but I'm not sure how I can edit the files so it deploys as arm64

[@DevOpsJourney]

If running on a M series Mac the architecture of minikube will be arm64. The key is to make sure our images are ARM64 compatible. The deployment is using the image devopsjourney1/mywebapp:latest - which does support ARM64. I only recently shipped the ARM64-compatible image, so you may have an older one cached. try removing and re-pulling devopsjourney1/mywebapp:latest. If that doesn't work then I will try creating a new image for you that is only ARM64. I think the issue might be that minikube doesn't always understand how to use multi-arch images properly

[@shellcasing1040]

How does ArgoCD know or detect which Kubernetes clusters are available to deploy to?

[@DevOpsJourney]

1. Create a kubeconfig file containing the cluster's credentials. 2. Login to ArgoCD and navigate to the Clusters page. 3. Select the “Create Cluster” button at the top right. 4. Select the type of cluster you want to add and provide the necessary credentials. 5. When prompted, select the kubeconfig file you created in step 1. Click Create CLI commands: argocd cluster add dev-cluster1 --name dev-cluster1 argocd cluster list

[@lotengproject]

nice nice nice nice ....

[@asandalamba7055]

"kubectl create namespace argocd" gives me "The connection to the server localhost:8080 was refused - did you specify the right host or port?"

[@DevOpsJourney]

Hey there. this sounds like your minikube environment is not running. Make sure docker is running then do a `minikube start`

Yes create a kubernetes ingress and point it to the argocd server service

yeah but a lot of companies want to be FMANG, and I like being paid by those companies :)
