yaml: unmarshal errors when having multiple deployments configs in the same file

[assapir]

we have a template with the following:

{{- if ... }} # this is always true by default
apiVersion: apps/v1
kind: Deployment
...
---
apiVersion: apps/v1
kind: Deployment
...

When trying to write a simple test, we get the following error:

                Error: yaml: unmarshal errors:
  line 63: mapping key "kind" already defined at line 2
  line 64: mapping key "metadata" already defined at line 3
  line 71: mapping key "spec" already defined at line 10

If I comment out the first deployment, everything is working as expected.

Hello @assapir,

I would need some more details on your scenario.
Using multiple deployment configs should not be a problem.
See the deployment.yaml in the base chart which contains multiple deployment configurations and have succeeding tests.

Would it be possible to add the complete file?

Greetings,

This happened when I accidentally chomped the whitespace before my document separator:

        controlledResources: ["cpu", "memory"]
        controlledValues: RequestsOnly--- # <--
apiVersion: apps/v1
kind: Deployment

Fixing that resolved the problem.
