Error messages are not human friendly

[howardjohn]

Example: error: MergeResourcesWithErrorOnIdCollision: id '"~G_v1_Namespace|~X|~P|istio-system|~S"' already used

I have no clue what all of these symbols mean which makes this hard to debug. I think this means I have a duplicate namespace defined?

Another example: error: rawResources failed to read Resources: GroupVersionKindName: resid.ResId{gvKind:gvk.Gvk{Group:"config.istio.io", Version:"v1alpha2", Kind:"attributemanifest"}, name:"istioproxy", prefix:"", suffix:"", namespace:"istio-system"} already exists b the map

This one is even harder to understand, what does "already exists b the map" mean?

It would be great if the errors could be more humanly consumable for a better UX

agreed. might try a later release though. not sure where you are, but (some of) those strings aren't in head.

I'm on kubectl Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.0", GitCommit:"e8462b5b5dc2584fdcd18e6bcfe9f1e4d970a529", GitTreeState:"clean", BuildDate:"2019-06-19T16:40:16Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"} so pretty recent, or does the kustomize support in kubectl lag behind?

[monopole]

kubectl 1.15 has kustomize 2.0.3 embedded.

Kustomize just released 3.0.0.

See https://github.com/kubernetes-sigs/kustomize/releases

Not saying the error messages are vastly better, but many other things are improved.

[howardjohn]

Cool, I'll have to check that out. Feel free to close this if its been improved

[monopole]

Yeah, I'm sure these are better, though not perfect.
You won't see ~P or ~S again, and id collisions errors are improved.

kustomize build $target | kubectl apply -f - 

with v3 kustomize and v1.15 kubectl is the best option right now.

Error message "already exists b the map" still exists in latest Kubectl. I'm not sure how to check the Kustomize version.

I was following the instructions from https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/

$ kubectl version --client
Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.4", GitCommit:"d360454c9bcd1634cf4cc52d1867af5491dc9c5f", GitTreeState:"clean", BuildDate:"2020-11-12T01:09:16Z", GoVersion:"go1.15.4", Compiler:"gc", Platform:"darwin/amd64"}

error: rawResources failed to read Resources: GroupVersionKindName: resid.ResId{gvKind:gvk.Gvk{Group:"", Version:"v1", Kind:"Service"}, name:"wordpress", prefix:"", suffix:"", namespace:""} already exists b the map

@johntellsall #1500 We have technical problems to update the kustomize version in kubectl. But we are working on it.
