vaihtovirta opened a new pull request #8132:
URL: https://github.com/apache/pulsar/pull/8132
### Motivation
Currently, pulsar functions written in Golang have no access to the content
of the user-config parameter from admin CLI.
That's the simplest way to pass custom configuration into a go function
right now because neither secretsMap nor Kubernetes runtime is available for
Golang functions yet.
**Note**: For the `secretsMap` parameter, the same technique can be used,
but this has to be addressed in a separate PR.
### Modifications
- Added `String GoInstanceConfig#userConfig` attribute
- Propagated user-config parameter in `RuntimeUtils.getGoInstanceCmd`
- Exposed userConfig in `pulsar-function-go` and made it available in the
`FunctionContext`
- Add unit tests for the affected code
### Verifying this change
- [ ] Make sure that the change passes the CI checks.
This change added tests and can be verified as follows:
- Added unit tests for `RuntimeUtils.getGoInstanceCmd` in
`pulsar-functions`
- Added unit tests for `instanceConf` and `FunctionContext` in
`pulsar-function-go`
