Error generating gotemplates for chart /helm: template: /helm:190: function "toYaml" not defined

[mcbenjemaa]

I'm generating my README from README.md.gotmpl

I'm setting this inside the README.md.gotmpl

    {{- .Values.container..resources | toYaml | nindent 4 }}

but, it's complaining with the following error

 Error generating gotemplates for chart /helm: template: /helm:190: function "toYaml" not defined

I'm getting a similar error:

Error generating gotemplates for chart /{{chart}}: template: /{{chart}}:120: function "fromYaml" not defined

I had the same problem. This isn't a problem with helm-docs per se, but with the underlying Go template engine.

See here for a solution: https://stackoverflow.com/a/51326166/928203b (note how they escape the curly braces at the end of the code snippet)

Thanks @sc250024 for the pointer, my problem was/is different, but also not caused by helm-docs. Well, at least not by the upstream version. See k8s-at-home/charts#1395.

Maybe I misunderstood this thread, but I found that the yaml functions are truly not available, so I added them here: #176
