Some of the pipelines in this PR crashed. I did a quick analysis:

Failure Analysis

The pipeline crashed during the helm lint step due to a YAML parsing error in the newly created pdb.yaml file. The error message indicates that there is an issue at line 7 of the file:

[ERROR] templates/pdb.yaml: unable to parse YAML: error converting YAML to JSON: yaml: line 7: mapping values are not allowed in this context

This suggests that there is likely an indentation problem or a syntax error in the YAML structure. Specifically, the maxUnavailable line appears to have incorrect indentation.

Suggested Fix

To resolve the issue, correct the indentation in the pdb.yaml file. The corrected version should look like this:

apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
  name: {{ .Chart.Name }}-pdb
spec:
  minAvailable: 3
  maxUnavailable: 2
  selector:
    matchLabels:
      app: {{ .Chart.Name }}

Ensure that maxUnavailable and selector are properly aligned with minAvailable under the spec section. After making this change, the pipeline should pass the helm lint step.
