Support Deployment mapping (similar to Service/Pod)

[philkuz]

Is your feature request related to a problem? Please describe.
Deployments are another type of k8s object that is mostly distinct from services and pods. Most importantly, it's possible that 2+ deployments back the same service so services might not be sufficient k8s objects in the future.

Describe the solution you'd like
Be able to query deployments like we query services/pods.

Describe alternatives you've considered
Most of the time services represent deployments 1:1, so you could use service queries to achieve what you want from Deployments. However k8s doesn't have any enforced constraint for this and it's possible for deployments to not back a service at all.

Hi @iamrajiv ! Thanks for your interest in this project! You should submit an application for GSoC once applications open in April. In the meantime, we recommend you try deploying Pixie yourself to see what it can currently do. You can take a look at our docs at docs.px.dev. Let me know if you have any questions!

When we do this, we should add deployment as a field in the Otel plugin export scripts.

This is now supported as of 57d2113! PR has also been submitted to update the OTel plugin scripts.
