Hi, Following our talk on TLS work items split, We need to decide how will we validate/extract certificates Barbican TLS containers. As we agreed on IRC, the first priority should be certificates fetching.
TLS RST describes a new common module that will be used by LBaaS API and LBaaS drivers. It's proposed front-end API is currently: 1. Ensuring Barbican TLS container existence (used by LBaaS API) 2. Validating Barbican TLS container (used by LBaaS API) This API will also "register" LBaaS as a container's consumer in Barbican's repository. POST request: http://admin-api/v1/containers/{container-uuid}/consumers { "type": "LBaaS", "URL": "https://lbaas.myurl.net/loadbalancers/<lbaas_loadbalancer_id>/" } 3. Extracting SubjectCommonName and SubjectAltName information from certificates' X509 (used by LBaaS front-end API) As for now, only dNSName (and optionally directoryName) types will be extracted from SubjectAltName sequence, 4. Fetching certificate's data from Barbican TLS container (used by provider/driver code) 5. Unregistering LBaaS as a consumer of the container when container is not used by any listener any more (used by LBaaS front-end API) So this new module's front-end is used by LBaaS API/drivers and its back-end is facing Barbican API. Please give your feedback on module API, should we merge 1 and 2? I will be able to start working on the new module skeleton on Sunday morning. It will include API functions. TLS implementation patch has a spot where container validation should happen: https://review.openstack.org/#/c/109035/3/neutron/db/loadbalancer/loadbalancer_dbv2.py line 518<https://review.openstack.org/#/c/109035/3/neutron/db/loadbalancer/loadbalancer_dbv2.py%20line%20518> After submitting the module skeleton I can make the TLS implementation patch to depend on that module patch and use its API. As an alternative we might leave this job to drivers, if common module will be not implemented What are your thoughts/suggestions/plans? Thanks, Evg
