Important: MSR 2.9.x reaches End of Life (EOL) on 2026-DEC-01. Mirantis strongly recommends upgrading to the latest supported version to continue receiving updates, fixes, and support.

Helm limitations

MSR API endpoints

For the following endpoints, note that while the Swagger API Reference does not specify example responses for HTTP 200 codes, this is due to a Swagger bug and responses will be returned.

# Get chart or provenance file from repo
GET     https://<msrhost>/charts/<namespace>/<reponame>/<chartname>/<filename>
# Template a chart version
GET     https://<msrhost>/charts/api/<namespace>/<reponame>/charts/<chartname>/<chartversion>/template

Chart storage limit

Users can safely store up to 100,000 charts per repository; storing a greater number may compromise some MSR functionality.
