Walkthrough

Helm defaults now define log levels for execution-manager, scheduler, and storage containers. Deployment templates expose those values through RUST_LOG, worker extra environment rendering is retained within its environment block, and the chart version is bumped.

Changes

Helm logging configuration

Layer / File(s)	Summary
Logging value defaults tools/deployment/spider-helm/values.yaml	Adds INFO defaults for execution-manager, scheduler, and storage log levels.
Deployment logging wiring tools/deployment/spider-helm/templates/*-deployment.yaml, tools/deployment/spider-helm/Chart.yaml	Injects configured log levels as RUST_LOG, keeps worker extra environment values in the environment block, and updates the chart version.

Estimated code review effort: 2 (Simple) | ~10 minutes

env and extra_evns?

Let's discuss, I think I am okay with the change in this PR, but might worth some refactoring for the extra_envs, extra_volumn_mounts and extra_volumn

[sitaowang1998]

We reached the following conclusion during offline discussion:

• Storage and scheduler should not accept extra environment variables for safety.
• Worker should have a standalone log_level instead of using extra_envs to:
  • Keep the same form as with storage and scheduler.
  • Avoid user accidentally overwriting the log level when adding new environment variables.

[LinZhihao-723]

I agree with the decision to split the log level to the default env.

Before merge: I think you should make the scope consistent with other PRs. Looks like we were always using feat(helm), not feat(spider-helm).
