Hi All: Here is the doc info for: Support for ICA signed ssl, docker_registry certifcate installation: (https://bugs.launchpad.net/starlingx/+bug/1883300) The fix is delivered as: https://review.opendev.org/#/c/740960/ https://review.opendev.org/#/c/740958/ With this bug fix released, ICA (intermediate CA) signed ssl, docker_registry certificate can be installed by the following command respectively: system certificate-install -m ssl <ssl cert pem file> system certificate-install -m docker_registry <docker registry cert pem file> An ICA signed ssl, docker_registry certificate contains the final server certificate, and the intermediate CA certificates signing the final server certificate. In the pem file passed to system certificate install command, the certificates should be ordered such that each of the certificate is signed by the succeeding one, with the final server certificate as the very first in the list. Please let me know if you have any questions. Thanks, Andy
