Code Review
This pull request correctly addresses the security finding by adding resource limits to the read_job.yaml test manifest. This is a good improvement for resource management and stability in the test environment. My review includes a suggestion to make the resource specification more explicit and complete by including requests and CPU resources, and also to right-size the resource values which currently seem excessive for the job's workload. Following these best practices, even in test files, improves overall code quality and consistency.

While setting memory and storage limits is a great step for security and stability, it's a best practice to explicitly set resource requests as well. When requests are not set, they default to the limit values. Explicitly setting them improves clarity and makes the resource requirements for scheduling clear.
Additionally, it's recommended to set CPU resources to ensure predictable performance and scheduling. For a Guaranteed Quality of Service (QoS) class, you can set requests equal to limits for all resources (CPU, memory).
The current values for memory (512Mi) and ephemeral storage (5Gi) seem excessively high for a simple job that runs cat. The samples/juicefs/read_job.yaml file uses 64Mi and 512Mi respectively, which seem more appropriate. I've adjusted the values in the suggestion to be more reasonable.
resources:
requests:
cpu: "100m"
memory: "64Mi"
ephemeral-storage: "512Mi"
limits:
cpu: "100m"
memory: "64Mi"
ephemeral-storage: "512Mi"
