PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Validate deployment replica count input Add input validation to ensure router replicas value is a positive integer. Without validation, setting negative or zero replicas could break the deployment. charts/selenium-grid/templates/router-deployment.yaml [17] -replicas: {{ .Values.components.router.replicas }} +replicas: {{ max 1 (.Values.components.router.replicas | int) }} Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion adds crucial input validation to prevent deployment failures by ensuring the replica count is always a positive integer, which is essential for maintaining service availability and preventing misconfiguration issues.	8

Hi, thank you for your contribution. Do you foresee any component else that needs to do the same?

Hi, thank you for your contribution. Do you foresee any component else that needs to do the same?

I'm not familiar enough with each component to be able to say for sure, but it might not hurt to make each of them configurable.

I can run through and change them all if you'd like

[VietND96]

Yeah, go ahead with your changes. I think this is a chance to move all replicas configurable from values

@joshfng, thank you! I added for the rest and will release a new chart
