PR Review

⏱️ Estimated effort to review [1-5]	3, because the PR includes a variety of changes across multiple files, including shell scripts, Helm templates, and GitHub Actions workflows. The changes involve conditional logic, Kubernetes resource definitions, and retry mechanisms in CI pipelines, which require a careful review to ensure they are correct and do not introduce regressions.
🧪 Relevant tests	No
🔍 Possible issues	Conditional Logic Error: In the chart_test.sh file, the elif condition seems to be a duplicate of the if condition above it, both checking if "${SELENIUM_GRID_AUTOSCALING}" = "true" and "${TEST_EXISTING_KEDA}" = "true". This might be a copy-paste error and could lead to unexpected behavior.
	Retry Mechanism Overuse: The use of the retry mechanism in GitHub Actions for building Docker images and setting up Kubernetes might mask intermittent issues that should be addressed directly.
🔒 Security concerns	No

PR Code Suggestions

Category	Suggestions
Bug	Revise the condition in the elif block to ensure it can be executed when conditions are met. The condition in the elif block is identical to the if block above it, which will cause the elif block to never execute. Consider revising the condition to reflect the intended logic. tests/charts/make/chart_test.sh [105] -elif [ "${SELENIUM_GRID_AUTOSCALING}" = "true" ] && [ "${TEST_EXISTING_KEDA}" = "true" ]; then +elif [ "${SELENIUM_GRID_AUTOSCALING}" = "true" ] && [ "${TEST_EXISTING_KEDA}" = "false" ]; then
Best practice	Use a specific version of the GitHub action to ensure stability. Using the master branch of a GitHub action can lead to unstable builds if changes are pushed to master. It's safer to use a specific version or commit hash. .github/workflows/build-test.yml [54] -uses: nick-invision/retry@master +uses: nick-invision/retry@v2.4.1
	Replace deprecated apt-key with a safer key management approach. Using apt-key is deprecated. Instead, use signed-by with trusted keys stored in /etc/apt/keyrings. Base/Dockerfile [58] -&& apt-key adv --keyserver hkps://keyserver.ubuntu.com:443 --recv-keys 843C48A565F8F04B || apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 843C48A565F8F04B \ +&& mkdir -p /etc/apt/keyrings \ +&& gpg --no-default-keyring --keyring /etc/apt/keyrings/ubuntu-archive-keyring.gpg --keyserver hkps://keyserver.ubuntu.com:443 --recv-keys 843C48A565F8F04B
	Use kubectl patch for more reliable and maintainable Kubernetes object modifications. The kubectl command in the job uses jq to modify JSON data, which is error-prone and hard to maintain. Consider using kubectl patch or a similar Kubernetes-native command if possible. charts/selenium-grid/templates/patch-keda/patch-keda-objects-job.yaml [33] -- "kubectl get ScaledObjects,ScaledJobs -n {{ .Release.Namespace }} -l component.autoscaling=true -o=json | jq '.metadata.finalizers = null' | kubectl apply -f -" +- "kubectl patch ScaledObjects,ScaledJobs -n {{ .Release.Namespace }} -l component.autoscaling=true --type=json -p='[{\"op\": \"remove\", \"path\": \"/metadata/finalizers\"}]'"
	Use a specific Docker image tag to ensure consistent and predictable builds. Using latest as a tag for Docker images can lead to unexpected behavior if the image is updated. Specify a fixed version to ensure consistent environments. charts/selenium-grid/values.yaml [16] -kubectlImage: bitnami/kubectl:latest +kubectlImage: bitnami/kubectl:1.21.1
