Cloud Foundry Advisory Board Meeting, Jan 2020: KubeCF Demo
The first Cloud Foundry Community Advisory Board (CAB) meeting of the new year focused on the KubeCF project. Michael Maximilien (a.k.a. Dr. Max) of IBM moderated the call and speculated the idea of letting some fresh blood in after being a major organizer of the meetings for over three years.
“I’ve been running the CAB meetings for three years. This is the fourth year and I’m not tired of it. I’m happy to meet with everybody, but at some point, it makes sense to give other people an opportunity to share new ideas.”
—Dr. Max, IBM
Dr. Max also shared the results of the CAB survey 2019. It appeared that the community truly enjoys demos of new projects, reports on their evolution and the status of the ongoing initiatives, as well an open exchange of ideas. The call featured regular updates from various members of the development teams and from the Cloud Foundry Foundation.
Cloud Foundry for Kubernetes
KubeCF resembles cf-deployment for Kubernetes distributions for Cloud Foundry. KubeCF is published as a Helm chart and container images.
According to Troy Topnik of SUSE, KubeCF relies on the Cloud Foundry Operator to run, which watches a namespace and uses a CRD to translate BOSH manifests into Kubernetes ones.
“KubeCF’s function as a central point to bring together components for a Kubernetes distribution is like that of
cf-deployment.” —Troy Topnik, SUSE
During the call, Thulio Assis of SUSE provided a demonstration of KubeCF. He also explained how KubeCF adds Kubernetes-specific functionality to

“KubeCF operation files are used to add functionality to
cf-deploymentthat is specific to Kubernetes, such as probes, health checks, or open and closed ports.” —Thulio Assis, SUSE
Currently, KubeCF can consume BOSH releases from
cf-deployment and Helm charts. The SUSE team is considering adding support for Kubernetes YAML and YTT templates. KubeCF v0.1.0 was released on December 26, 2019, and is waiting for a community feedback. This version includes Eirini v1.0, App-AutoScaler v3, and
cf-deployment v12.18. Now, KubeCF v0.1.0 passes Cloud Foundry acceptance tests (CATs) with Diego. KubeCF v0.2.0 is expected soon, and a stabilized v1.0.0 is scheduled for March 2020. For additional details, you can check out this presentation.
Eric Malm of Pivotal provided the following updates:
- The Release Integration team is delivering automated, semiweekly updates to
cf-deployment. The team is also starting integration support for the Component teams, which are working on Kubernetes deployments artifacts. A community proposal document will be published soon.
- The CAPI team is enabling Kubernetes deployment artifacts for the Cloud Controller, as well as an integration between the Cloud Controller and kpack to run cloud-native buildpack staging tasks.
- The UAA team is progressing on Kubernetes deployment artifacts for UAA.
- The Networking team is continuing work on the CF-Route Sync component to translate Cloud Foundry routes into Istio and Kubernetes resources.
- The Loggregator team is starting early development on components for the shared-nothing architecture integrated with Kubernetes.
Morgan Fine of Pivotal reported that the BOSH team is working on exposing such BOSH Director metrics as:
- the number of unresponsive virtual machines
- free IPs
- resurrection status
- the number of processing tasks
- the number of queued tasks
CF Foundation updates
Following one of the options from the previous CAB meeting in December, Swarna Podila noted that the Cloud Foundry Summit will be collocated with Open Source Summit, the Linux Foundation’s anchor event. The North American summit will be held in Austin, Texas, on June 25, 2020, and the European summit will take place in Dublin, Ireland, on October 29, 2020. Additional details will be announced soon.
Chip Childers added that the Foundation will host cloud tracks at the Open Source Summit. These will be focused on contributors and end users.
Swarna also reached out to anyone looking to be mentors for students who are interested in becoming a Cloud Foundry contributor. Any volunteers can contact Swarna directly.
The next CAB call is scheduled for Wednesday, February 19, 2020. The call will start at 8 a.m. Pacific Time. Anyone interested can join Cloud Foundry’s CAB Slack channel.
