Error: json: unknown field "envs" when building the example in docs

[yujunz]

It seems caused by the secretGenerator.

~/go/src/sigs.k8s.io/kustomize/ master
❯ kustomize build docs
Error: json: unknown field "envs"

❯ kustomize version
Version: {KustomizeVersion:v2.0.3 GitCommit:a6f65144121d1955266b0cd836ce954c04122dc8 BuildDate:2019-03-18T22:15:21+00:00 GoOs:darwin GoArch:amd64}

The error will disappear if we modify envs to env, e.g.

secretGenerator:
- name: env_file_secret
  # paths to files with k=v pairs, one pair per line.
  env: env.txt
  type: Opaque

Is there a change in the spec recently?

[Liujingfang1]

@yujunz Yes, the env is changed to envs recently in #1041.

Note if you are using kubectl 1.15.3, it's still env and not a list as shown above.

Does this change have Backward compatibility? I think this should be considered.

[brannondorsey]

It looks like the Kustomize docs still refer to the old env property: https://kubectl.docs.kubernetes.io/pages/reference/kustomize.html#secretgenerator

Just got caught by Error: json: unknown field "env" and was lucky to find this issue. Using envs: worked.

[brandonkrull]

env -> envs also applies to configMapGenerators (kubectl v1.18, kustomize v3.8.1)

[hermanbanken]

Relates to #2205 and #2506

I'm from 2021. The issue is still there =)

@ThePlenkov The version of kustomize in kubectl is still not up to date - it's on v2.0.3. We VERY recently reintegrated the latest version of kustomize into kubectl. In the next release of kubectl (which is coming soon), kubectl apply -k will use kustomize v4.0.5.

[weltonrodrigo]

Guys, this is not a rant, but it's SO frustrating using kubectl -k because of those small incompatibilities. No to mention the VERY unexpected behaviour of kubectl kustomize being dependent of cluster version.

In one moment I'm in a context where envs exists and in another Error: json: unknown field "envs".

If kustomize is a manifest building tools, this is very unexpected and using it for two years now, totally unknow to me.

Anyway. Thanks for this great software. Keep up the good work.
