addisonj opened a new pull request #5400: [functions] Allow functions to pass runtime specific options URL: https://github.com/apache/pulsar/pull/5400 ### Motivation This commit adds a new argument for functions, customRuntimeOptions, which is passed to funcions (as well as sources/sinks) that enables the ability to customize the runtime. This is added primarily to support the `KubernetesManifestCustomizer` interface. This interface is intended, as the name indicates, allows for customizing how the kubernetes manifests are generated before they are sent off to the k8s cluster. This interface has a default implementation, which allows for changing the namespace, labels, nodeSelector labels, and toleratations per function. This interface is also pluggable, allowing for more customized implementations. For example, the functions for a given tenant could be mapped to different pools of compute for isolation. ### Modifications For the CLI and protobufs, the modifications just involve plumbing through the new option, `customRuntimeOptions` through the relevant code. For kubernetes runtime, the modifications are fairly straight forward, adding a new configuration option, `kubernetesManifestCustomizerClassName` and `kubernetesManifestCustomizerConfig` which are options under the kubernetes runtime. ### Verifying this change - [ ] Make sure that the change passes the CI checks. This commit adds some tests: - Adds tests for the kubernetes runtime with the default and custom implementation that validates the manifest files generated - passes existing unit tests ### Does this pull request potentially affect one of the following parts: *If `yes` was chosen, please highlight the changes* - Dependencies (does it add or upgrade a dependency): no - The public API: no - The schema: no - The default values of configurations: no - The wire protocol: yes, only of functions protobufs, adds a new field, customRuntimeOptions, which is a simple string - The rest endpoints: no - The admin cli options: yes, adds `custom-runtime-options` flags to the create/update commands for functions, sources, and sinks, which populates the above protobuf field - Anything that affects deployment: (yes / no / don't know) ### Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented? yes, docs - If a feature is not applicable for documentation, explain why? - If a feature is not documented yet in this PR, please create a followup issue for adding the documentation
