Using Helm Charts to Provision All-in-One Contrail with OpenStack Ocata

 

Note

Starting in Contrail Release 1912.L1, Helm support is unavailable in Contrail Networking. The Helm support content in this document supports Contrail Networking Releases 1907 through 1912.

This is the installation procedure for using Helm charts to provision an all-in-one Contrail system with OpenStack Ocata. This is not a high availability configuration.

Note

All-in-one systems are only used for testing or for demonstration purposes.
