Hello everyone,
We released KubeCF 1.0 today!
https://github.com/cloudfoundry-incubator/kubecf/releases/tag/v1.0.0
A big thank you to everyone that has contributed to this new flavor of Cloud Foundry!
We invite the community to try things out and help us make it better.
We'd also like to ask for your help. We are reorganizing the kubecf development teams,
and there is room for new contributors. If you want to help shape this project,
please come talk to us on the #kubecf-dev channel. No prior kubernetes experience needed.
Cheers,
Vlad

Hello CF Community! We wanted to share a document[1] that describes some best practices, and solicit feedback for instrumenting workloads in cf-for-k8s. From a metric standpoint we are making good progress in cf-for-k8s on container metrics (see our metric proxy[2]) and are starting to move towards metrics from other platform components. The major difference here is that we are no longer utilizing Loggregator envelopes, and are moving to a Prometheus exposition standard. We are here to help if your component is using something like statsd and needs to convert to Prometheus. The document should be open to comments and suggestions so please make your comments there. 1. https://docs.google.com/document/d/1XdkqIJ2SeqajNyzyTOjLg_VjuatSTCtown4-0xZEH3Q/edit#2. https://github.com/cloudfoundry/metric-proxy

Re: Bi-weekly Round-Up: Technical + Ecosystem Updates
Hope you’re all healthy, relaxed and washing your hands regularly. Many events are being canceled, as you’ve *probably* noticed. KubeCon + CloudNativeCon Europe (originally set for March 30 to April 2, 2020) has been postponed to July or August 2020. Unfortunately, KubeCon + CloudNativeCon + Open Source Summit China in July has been canceled altogether. Read more here.
From the Last Few Weeks:
- The CF community is looking for a handful of volunteers to help reconstitute a multi-member vulnerability management team for CFF projects. Message here.
- The Services API team has been working on a model for the Cloud Controller V3 API for Service Instances. You can view the proposal here. Also, they have an opening for project lead. VMware has nominated Miguel Luna for the role. Message here.

BOSH OpenStack CPI maintenance
Dear Friends of OpenStack,
SAP announced in August 2019 [1] to stop the maintenance of the BOSH OpenStack CPI and related projects by the end of 2019. Pivotal/VMware jumped in to take over the maintenance of the CPI. The handover has
been completed and Pivotal/VMware now officially maintains the BOSH OpenStack CPI [2]. To get support please reach out to #bosh [6] or #bosh-core-dev [7] Slack channels.
The CF OpenStack validator [3] and bosh-openstack-environment-templates [4] are now unmaintained and will be moved to the cloudfoundy-attic [5] organization after a short grace period.
Kind regards,
Morgan and Felix

Networking and Service Mesh in CF-for-k8s
Gabriel Rosenhouse <grosenhouse@...>
On the SIG CF for Kubernetes call this morning we discussed Networking, Routing and Service Mesh topics in detail.
A recording is available here. Thanks to the Cloud Foundry foundation staff , Swarna and Bree, for making the recording available.
Here are some rough notes I took from our call. Feel free to reply with corrections, feedback and questions.
1. What kind of feature parity are we targeting for networking in CF-for-K8s vs CF-for-BOSH?
The 1.0 release will provide basic http(s) ingress to apps and system components, log stream for apps, documented log and metrics for operational visibility, and transparent mTLS at every workload.
Some things will be more expensive for us to re-implement using the new networking tech stack in cf-for-k8s We don't expect to get those done before a 1.0 release.
Support for Application Security Groups (ASGs) and app-to-app network policies will not block the 1.0 release. We hope to deliver those soon afterwards. However, in the 1.0 release we will ship with deny-by-default for both app-to-app and app-egress (ASG-managed). The alternative, where 1.0 has allow-by-default, and a 1.x moves to deny-by-default, would result in a user-facing breakage during thee upgrade.
Because the vast majority of CF Apps need some kind of app-egress in order to function, we will recommend that, while waiting for support for Cloud Controller-defined ASGs, an operator could instead use Kubectl to apply their own Kubernetes NetworkPolicy objects to provide app egress allow rules. Such NetworkPolicy objects will continue to work even after CF-for-K8s is enhanced to provide full support for ASGs. Similarly for app-to-app network policies.
The caveat is that such operator-specified NetworkPolicies, like any kubernetes object created directly by the operator, will not be exposed to Cloud Foundry app devs. There is a risk that these allow-rules will be present without users being aware. As with any production system, we recommend that the operator regularly audit all network policies.
2. Current dependency on Istio. What's up with that?
We recognize there are legitimate concerns about the governance of Istio, its complexity and it's resource consumption. We don't expect that Cloud Foundry will have a hard-dependency on it, and aren't attached to it in the long-term.
App Developers won't use the Istio API directly.
Operators may touch a bit of it here or there when installing CF-for-K8s, but it should be narrowly scoped. In the near-term, we won't be supporting the Istio API beyond those narrow, operator-facing bits. Custom Istio config (or network policy, for that matter) voids your warranty.
We could consider leaning on the Service Mesh Interface (SMI) as an abstraction layer if there's demand for swappability, although we haven't yet looked at it's suitability, and we're not committing to supporting this in the short-term.
Istio does provide value in transparent mTLS everywhere, and that's a big part of why we're using it right now. Although alternatives like Linkerd may be worth considering instead.
3. Could migration from CF-for-BOSH/Diego to cf-for-k8s be eased by service-mesh-style connectivity between a Diego cluster and a K8s cluster?
Yes. If we want to zero-downtime-deploy apps to cf-for-k8s, it is reasonable for those apps to be able to connect back to apps deployed on cf-diego. Also apps on cf-diego being able to connect to apps on cf-for-k8s.
IP connectivity between containers across clusters would be nice, but many vendors & users don't have this.
CF-for-BOSH-diego has Envoy proxies in each app instance, but they aren't managed by Istio in supported releases (we've ceased development in the istio bosh release).
Alternative solution may involve: share internal route data across clusters, update DNS so that diego clients connect to a cluster-local egress-gateway, which can mTLS tunnel to an ingress gateway in the remote cf-for-k8s cluster. The reverse could happen from client sidecars and skip the egress gateway. This would require quite a bit more technical design to de-risk, but seems viable.
Happy to field questions and corrections over reply email, or ping me in #cf-for-k8s in cloud foundry slack.
Thank you!

Subject: Re: [cf-dev] Deprecation of cf-syslog-drain-release
Hi Jesse,
Do you have a rough schedule when you want to remove the adapters and disable cf-syslog-drain release in cf-deployment?
Our current plan is to ship this in cf-deployment v13.0.0 (in coordination with the Release Integration team).
Is it in weeks or months?
This is dependent on cf-deployment's release schedule.
Will there be an ops file to opt out of the new architecture for some time once it got the default?
We do not presently plan to offer this, for a couple reasons:
1) The add-syslog-agent.yml ops file has existed as an opt-in for some time.
2) The new architecture will change which parts of the foundation are impacted by high syslog output, but does not result in any other change for operators or developers. The syslog output format and configuration mechanism should be unchanged.
We are planning to offer an ops file in cf-deployment v12 that will put the syslog agents in place, ready to be flipped on in v13, so that the upgrade takes less time and causes much less downtime in app syslog drains.
Best regards,
Stephan

Subject: [cf-dev] Deprecation of cf-syslog-drain-release
As previously announced [1], the Loggregator team has developed a new way to forward application logs over syslog using agents, rather than centralized adapters. This
new approach can scale to higher log volume and numbers of app drains, and allows log egress from CloudFoundry without any dependence on the Loggregator firehose.
We have had an ops file[2] to switch to this new architecture in cf-deployment for some time, and are working to make it the default in a coming major version of cf-deployment. This would mean the removal of the scalable-syslog architecture, with its schedulers
and adapters, and the cf-syslog-drain release.
Once this has been released, we would like to mark the cf-syslog-drain release as deprecated, and halt development.
Please let us know if you have any concerns or questions.
