91-91: Improved YAML structure forstorageClassNameThe indentation of the
storageClassNamefield has been corrected, aligning it properly with other fields in thevolumeClaimSpecsection. This change enhances readability and maintains a consistent YAML structure without altering the functionality.charts/heimdall/templates/heimdall/statefulset.yaml (2)

144-148: Approved: Consistent use of dumb-init and improved command formattingThe changes in the main Heimdall container are well-implemented:
- Using
dumb-initto executeheimdalldfor the main process ensures consistent process management across the container lifecycle.- The formatting changes to the command arguments improve readability without altering functionality.
For consistency with the init container, consider using the full path to
dumb-init:- exec /storage/dumb-init -- heimdalld start \ + exec /storage/dumb-init -- heimdalld start \This minor change ensures that the same
dumb-initbinary is used in both containers.

211-216: Approved: Consistent use of dumb-init in REST server and improved command formattingThe changes in the Heimdall REST server container are well-implemented and consistent with the other containers:
- Using
dumb-initto executeheimdalld rest-serverensures consistent process management across all containers.- The formatting changes to the command arguments improve readability without altering functionality.
For consistency with the other containers, consider using the full path to
dumb-init:- exec /storage/dumb-init -- heimdalld rest-server \ + exec /storage/dumb-init -- heimdalld rest-server \This minor change ensures that the same

18-18: LGTM: Version increment is appropriate.The chart version has been correctly incremented from 1.2.4 to 1.2.5, which is consistent with semantic versioning for a new feature addition (dumb-init) as mentioned in the PR title.
Let's verify if this version change is consistent across other relevant files:
✅ Verification successful
Version consistency confirmed across relevant files.
The version
1.2.5is correctly updated inChart.yamlandREADME.md, and no occurrences of the old version1.2.4remain.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Check if the version 1.2.5 is consistently used across relevant files # Test: Search for the new version number in other files rg --type yaml --type md '1\.2\.5' # Test: Ensure no occurrences of the old version remain rg --type yaml --type md '1\.2\.4'Length of output: 554

66-68: Excellent addition of dumb-init for improved process managementThe incorporation of
dumb-initis a great improvement to the container's process management. Here's why:
- It ensures proper signal handling and zombie process reaping.
- Moving
dumb-initto a shared storage location (/storage/dumb-init) makes it available for use in other containers.- Using
dumb-initto executeheimdalldduring initialization (line 74) is consistent with the goal of preventing zombie processes.These changes will lead to more robust and reliable container behavior.
Also applies to: 74-74
Line range hint
1-280: Summary: Excellent implementation of dumb-init for improved process managementThe changes in this file consistently implement
dumb-initacross all containers (init, main Heimdall, and REST server). This improvement will:
- Ensure proper signal handling and zombie process reaping.
- Lead to more robust and reliable container behavior.
- Reduce the risk of resource leaks due to orphaned processes.
The minor formatting changes also improve the readability of the configuration without altering its functionality.
Overall, these changes represent a significant improvement in the Heimdall deployment's process management and maintainability.
