Proper kustomize syntax to replace the value of list element with condition

[kastl-ars]

Given this YAML file, what would be the proper syntax to patch the value of the env element that has TRACING_COLLECTOR_HOST as name?

This works, but hardcodes "use the second element in the list" (.../env/1/...):

- op: replace
  path: /spec/template/spec/containers/0/env/1/value
  value: newvalue

I find no syntax that kustomize accepts, that lets me define this. Is this possible?

The RFCs for JSON patches contain only very basic paths, unfortunately.

yq accepts something like this:

.spec.template.spec.containers.0.env[] | select(.name == "TRACING_COLLECTOR_HOST").value

Here are some of the things I tried with kustomize:

  path: /spec/template/spec/containers/0/env/(.name == 'TRACING_COLLECTOR_HOST')/value
  path: /spec/template/spec/containers/0/env[](.name == 'TRACING_COLLECTOR_HOST')/value
  path: /spec/template/spec/containers/0/env/(.name == 'TRACING_COLLECTOR_HOST')/value
  path: /spec/template/spec/containers/0/env/(name == 'TRACING_COLLECTOR_HOST')/value
  path: /spec/template/spec/containers/0/env/(/name == 'TRACING_COLLECTOR_HOST')/value
  path: /spec/template/spec/containers/0/env/name == 'TRACING_COLLECTOR_HOST'/value
