Summary of Changes

Hello @rennokki, 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 primarily addresses code style inconsistencies identified by StyleCI. It includes formatting adjustments in a core class and a minor type hint correction in a test file, ensuring adherence to established coding standards and improving code readability.

Highlights

• Code Style Formatting: Applied automated code style fixes, specifically reformatting break statements in switch cases to appear on new lines within the loadFromConfig method in src/KubernetesCluster.php.
• Type Hint Adjustment: Modified the test_from_environment_variable method signature in tests/ConfigurationTest.php to explicitly allow null for the $context parameter using a nullable type hint (?string).

Code Review

This pull request applies some automated style fixes from StyleCI. The changes improve code formatting in a switch statement and update a method signature to use modern nullable type syntax, which is good.

However, I've found a critical issue in src/KubernetesCluster.php where there's a mismatch between a connection driver name in the code (variable) and in the default configuration file (environment). This bug prevents the environment connection from working as intended. I've left a specific comment with a suggestion to fix this.

[gemini-code-assist]

There's an inconsistency between the driver name used here (variable) and the one defined in the default configuration file (config/k8s.php), which is environment. This will cause the 'environment' connection from the config to fail silently by falling through to the default case. To fix this, the driver name should be consistent. I suggest changing this to environment to match the configuration file.

Note that this change will require updating tests/ConfigurationTest.php to use the environment driver in test_from_environment_variable for the tests to pass.

            case 'environment': $this->configureWithKubeConfigVariable($config);
                break;
