fix(security): Memory limits should be enforced in test/gha-e2e/juicefs/write_job.yaml.

[JiGuoDing]

Ⅰ. Describe what this PR does

This PR addresses the security finding “Memory limits should be enforced in test/gha-e2e/juicefs/write_job.yaml”.

The code below demonstrates how to securely configure a Kubernetes Job with constrained resource usage by explicitly setting:

resources:
  limits:
    memory: "512Mi"

Ⅱ. Does this pull request fix one issue?

fixes #5364

Ⅲ. List the added test cases (unit test/integration test) if any, please explain if no tests are needed.

Ⅳ. Describe how to verify it

Run the test setup to see if there still remain code scanning alerts.

Ⅴ. Special notes for reviews

Summary of Changes

Hello @JiGuoDing, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a crucial security enhancement by introducing a memory limit to a Kubernetes Job definition within the end-to-end test suite. The change ensures that the write_job.yaml adheres to resource constraints, mitigating risks associated with unconstrained memory usage and bolstering the stability and security of the test environment.

Highlights

• Security Fix: Addressed a security finding by enforcing memory limits in the write_job.yaml Kubernetes configuration.
• Resource Management: A memory limit of "512Mi" has been explicitly set for the test job to prevent potential resource exhaustion.

Code Review

This pull request correctly addresses the security finding by adding a memory limit to the write_job.yaml. This is a good improvement. I've added one suggestion to further enhance resource management for this job by also including CPU limits and resource requests, which is a Kubernetes best practice. You might consider applying a similar change to read_job.yaml for consistency across the test jobs.

[gemini-code-assist]

While adding a memory limit is a great step for security and resource management, it's also a best practice to define CPU limits, as well as both CPU and memory requests. This ensures more predictable performance and better scheduling by Kubernetes. For a simple job like this, the requests can be small.

        resources:
          limits:
            ephemeral-storage: "5Gi"
            memory: "512Mi"
            cpu: "500m"
          requests:
            memory: "64Mi"
            cpu: "100m"
