Awesome series on ArgoCD. I have learnt a lot from your channel. You helped me a lot and i am sure lot of others in Kubernetes learning journey. I am requesting you to please add apps of apps or cluster bootstrapping as well as part of this series. Thanks a lot again.

Nice series Venkat, you made it very simple and easy to understand .Can you please also make a series in Tekton CI/CD and integrate with ARGO ? Appreciate all your effort as always !

Hi venkat thanku very much for all the vedios 👍🙏.u have done vedios on istio mesh can u please do one more vedio on ingress to istio mesh using (kong ingress controller) . Thank u very much 😊😊

[@justmeandopensource]

Hi Aditya, thanks for watching. Kong is in my list and I will get to it in few weeks time as I have couple more videos scheduled before that. Cheers.

If i want to pass the username and password to that particular repository along with the argocd cli command ?

[@asthab7503]

Hi Venkat Thanks for the amazing explaination. This video series is really helpful. Could you please tell if there any way of automating the updation of changes in the git repo based on new artifact creation in Jenkins? (say new docker image is created via jenkins and pushed to docker image registry - can this image name get updated in git repo monitored by Argo without manual intervention?) Basically combining CI and CD part in a single flow. If yes, it would be great if you can create a video on that part as well.

[@justmeandopensource]

Hi Astha, thanks for watching. That should be part of your CI/CD workflow. Your jenkins pipeline will be building the image and pushing to the image registry and also update the Git manifests with this new docker image. As it updates the Git repo, Argo CD will pick it up and deploy the new version. Cheers.

[@madhuboyina]

Hi Venkat, tried installing argocd cli on mac, and get the error "zsh: exec format error: argocd". Can you please assist

[@teknikalyfit]

IMO cli is a bit overhead and downgrading declarative to imperative. yaml crds are the best way to talk with argo and then kubernetes. With kustomize, DRY rules fit better. Great thanks for your clean tutoring.

[@bikramdas3461]

Hi Venkat , While deleting app 'traefik' which installed via helm using argo cd getting 'level=fatal msg="rpc error: code = InvalidArgument desc = Application.argoproj.io \"traefik\" is invalid: metadata.finalizers: Forbidden: no new finalizers can be added if the object is being deleted, found new finalizers []string{\"resources-finalizer.argocd.argoproj.io\'" . Argo-cd-2.0.2 version . kubectl delete app did not work . Can you please guide.

[@claudiogarcia7557]

Hi Venkat ! first of all , excellent videos as usual, I have setup an argocd and k3s (one node) both running at the same machine and it is working fine, is it possible when you get a chance make a video showing how to add another K3S cluster (one node) to existent argocd? thank you very much

[@justmeandopensource]

Hi Claudio, thanks for watching. I will add it to my list and give it a try. Cheers.

[@varshachougule8319]

Hi Vekant , how to pass env variable value in values.yaml of helm chart using argocd cli commnad?

[@justmeandopensource]

Hi Varsha, thanks for watching. I know I am responding to a very old comment and I guess you must have found the solution yourself by now. If not, check this link argoproj.github.io/argo-cd/user-guide/helm/ Basically you can use argo app set command to change the values.

[@chalakaillangasinghe2981]

Hi Venkat what is the bash completion tool you are using ?

[@justmeandopensource]

Hi Chalaka, thanks for watching. I use Zsh shell with zsh-autosuggestion plugin for command suggestion based on my previously entered commands from zsh history. Done a video a while ago on my terminal setup. You can watch it here if interested. I don't use the exact setup now, but the concept is the same. kzbin.info/www/bejne/qaCkqIinZ8iEfrM

[@ylcnky9406]

Hey thanks for the great series. Have you come up any way to automate the deploys with Docker image tags? Basically whenever a new image is published to a Docker registry, Argo will track the version and update the app.

[@ralphotowo5142]

Hi @ylcnky, great question. Did you figure this out?

[@ylcnky9406]

@@ralphotowo5142 not really the way I would like to. I think Argo does not have any built in function yet. I made a work around by making Argo listening a specific yaml file in which I am updating the tags automatically. So whenever there is a change in that yml (which is due to image tag) it pushes the repo and fetches the new image.

[@cnuk1515]

thanks for amazing ArgoCD videos, learned many things under an hour. BTW, how can we restrict ArgoCD users to a deploy to a certain namespace only, and set up per namespace access for the CLI and Argocd UI?

[@justmeandopensource]

Hi, thanks for watching. Argocd actually uses a clusterrole I believe and when you add a new cluster to deploy apps to, you can configure the roles accordingly.

[@cnuk1515]

@@justmeandopensource read about projects which appear to help to restrict deployment to configured namespace and other restrictions. Need to read up on that.

[@justmeandopensource]

@@cnuk1515 I see.

Hi Adil, thanks for watching. What do you mean?

[@ibrahimmohammed3386]

how to proceed if argocd requires authentication to access github repo? Is it possible to use github actions to create argocd app using cli inside github workflow

[@justmeandopensource]

Hi, thanks for watching. I haven't tried github actions yet. So can't comment. I will see if I can test this. Cheers.

[@justmeandopensource]

Hi Sai, thanks for watching. Are you experiencing this issue when deploying argo cd or are you having this issue in general in your cluster when you run any workloads?

[@amitabhprasad]

is that the right way to get password ? I think it's now in `argocd-initial-admin-secret`

[@justmeandopensource]

May be not with recent versions of argo.

[@makrand1584]

Hi Venkat, Hope you're doing good. I have tried setting up argocd on K8 cluster running on LXD. I am facing issues there. I am getting i/0 errors on redis and repo-server pods. Here are details - github.com/argoproj/argo-cd/issues/4174. This is looking more enviornment spefic issue. Hence curious if you have tried argocd on K8 cluster running on LXD? Great Video as usual. Keep it up.

[@justmeandopensource]

Hi Makrand, I haven't tried this in lxd environment yet. I had been using K3d lately. Will give it a try.

[@justmeandopensource]

Hi Makrand, I just gave it a try and it worked for me. All Argo services/deployments running fine. I can log into web ui. One thing I noticed was that, initially I couldn't log into the web ui. But after 10 minutes I was able to. More details in this link. pastebin.com/R5ZyKNF4

[@makrand1584]

@@justmeandopensource Venkat, Thanks for reply. Have you tried deoloying any app from GUI of argocd? (Or even from manifest in declarative style) I am facing those errors while tried deploying an app. My deployed app eventually turns healthy, but the sync status remains unknown & those errors keeps popping. All errors are presented in github issue I created. Otherwise just the argocd pods are running fine for me with GUI accessible.

[@justmeandopensource]

@@makrand1584 Ah I see. Will have a look at the issue and do bit more testing.

[@justmeandopensource]

Hi Makrand, I now see your issue and getting the same error. I can't deploy any app. Tried web ui, declarative way and argocd cli way. Some networking issue underneath. To be honest, I am not using lxd for Kubernetes these days due to lack of support. Hopefully someone gone through this hurdle will give you some advice.
