Regarding release name

[vasusharma1]

If we are changing release name as "A" to "A-canary" , then wouldn't it be less beneficial as our new release name will become "A" to "A-canary" ?
Please, clarify how to upgrade and during it change release name from "A" to "B"

I see what you mean @vasusharma1 - how the canary version works right now is we build a new release for canary analysis and then when we want to release a production deployment we just remove this canary release. The canary release doesn't get promoted.

This is mainly just because of some limitations with helm scripting.

1. I was actually deploying it, so i was unable to create in same namespace it was giving me error of kube-dns already exists.
2. If i was doing it in different namespace but then it was giving me already used port error.
3. Moreover, so say for example i am using "A" release in production, so i will release canary version in same namespace or different namespace?, after i come to know it is working fine then what will be my next course of action?
   Please, it will be great help to me if you can clarify all three points technically.

Ya there are some tricky pieces to get this working right, I've only tested the workflow with the chart in this repository (at ./charts/app) I explain the process in a blog post here: https://deliverybot.dev/2019/09/14/safe-and-automation-friendly-canary-deployments-with-helm/ One of the key things with this style of canary deployments is that you can't have conflicting resources in between your charts. With everything working successfully you will have two helm releases: - myapp - myapp-canary If any of the resources conflict between those releases, then it will fail to deploy the canary. My guess is that when you are rolling out your canary deployment you have conflicting resources. For example a Deployment resource or Service resource have the same name. To confirm this if you could post the helm chart that you are using and some examples of Kubernetes manifests I could probably help more to debug the problem.

Sorry unfortunately i cannot share chart, but yes i think you are right name of my deployment is same because of which i might be having this issue. Let me try it once again after changing deployment name and following your post. I'll update status if i went into trouble in this thread and if everything works fine i'll close it.
Thanks a lot for your help.

Moreover, so say for example i am using "A" release in production,
so i will release canary version in same namespace or different namespace?,
after i come to know it is working fine then what will be my next course of
action?
What are your suggestions for this?

Hey sorry @vasusharma1 a bit late on this one.

I think that different namespaces is up to you as long as the release name doesn't conflict. Overall I would probably go for the same namespace as that'll be easier to understand.

thanks @colinjfw
