Re: Announcing Cloud Foundry CLI v7 Release Plan

Greg Cobb
 

For now, application manifests will remain the same.

We did recently introduce versioning to manifests, which will allow us to iterate on manifest structure and features more aggressively in the future (and independently from API/CLI version).

Hands on Labs at CF Summit

Chris Clark
 

Hello folks, 

As you've likely heard, Cloud Foundry Summit will be a virtual event for the first time. While I'm disappointed we won't all be gathering together in Austin, there is some upside to a virtual summit. With fewer time/space restraints, Summit will run for two days, not one, and we'll be having technical Hands on Labs sessions each day.    

As far as the labs go, we're still in the planning stages, and we wanted to reach out to the community and ask a few questions:

What kind of technical lab/demo content would you want to see included?  
Any particular topics you think we'd be remiss to exclude?  

If you've recently attended any virtual events, any wisdom you'd like to impart on how hands on labs were organized, and how successful they were (or weren't)?  

Are you or your project team interested in running a lab?  

Feel free to respond publicly, or to me directly.  Hope you're all safe and healthy out there.

Re: Exploring CRDs in CF

Angela Chin
 

Hi folks,

Thanks Zach for starting this thread. There's been some good conversation in the document about different reasons and benefits of using CRDs.

Connor (cc'ed) and I have been exploring what introducing CRDs to Cloud Foundry might look like centered around the different outcomes described in the doc. We've generated this document (titled "CF App Runtime CRD Approaches") and would love to have feedback and a discussion via comments.

Hey all,

As we move towards a kubernetes-based Cloud Foundry, the inclusion of CRDs into CF has been a recurring topic. At this point we already see CRDs being incorporated into CF in a number of ways, as well as questions about them such as a thread on this list titled "Is anyone working on a CF CRD & Controller?".  

We would like to use this space to start gathering an understanding of how folks are using CRDs, the reasons folks are using CRDs, and what CRDs folks would like to see in the future. 

This will help us build a better understanding as a community towards the outcomes of
  • Include CRDs in CF with well-defined architectural patterns
  • Understand how CRDs should be exposed as a user interface

This document has been created to help house the discussion asynchronously. It has been built with the understanding of cf contributors from a couple of teams, but we need everybody's help to flesh out the full picture.

Looking forward to discussion

Yes, this is the current approach for the CRDs that Cloud Controller interacts with now. There are also reconciliation loops that we run for these resources analogous to how we've always reconciled CCDB state with Diego.

I think this method has developed organically from our goal of preserving in-place workflows via having the same API surface, allowing cli to function without changes, while trying to consume existing functionality in k8s. I think the longer term goal here is to review that usage and be more intentional about how we expect CRDs to fit into the system as a whole.

It's great that folks are already thinking about this.

Zach, am I correct in thinking that the current approach is the have clients interact with CloudController, have CloudController persist to CCDB as per usual, and then CloudController post stuff to CRDs in the Kube API?

I'd kinda imagined things going the other way around, introducing the CRDs as a new user interface, and have the controllers do the diff and then post/put to CloudController. The intention here would be saving Kubes-native folks (and CI servers!) from having to deal with the imperative interface. I was working on the assumption that all CF concepts would be exposed as CRDs.

From a CAPI perspective, I've been thinking more about representing apps and push as CRDs, and I believe the Eirini team has some thoughts in this area as well.

I'd always dodged this area in cf-converger as it was the most complicated, and the biggest break from the current CF experience :)

For example when we look at orgs/spaces - we have to wonder if those are even resources we want to represent as CRDs, when k8s already has a namespace construct.

I can imagine that the logical concept of orgs may one day map onto distinct Kubernetes namespaces, but I hadn't imagined that orgs would in any way disappear, or not be configurable via the Kubernetes approach.

It'd be great to hear what others think on all of this.

Thanks again for sharing, Keshav and Zach.

Hey Daniel,

Thanks for starting a convo. The timing couldn't be better. I can share some of the thinking going on in both CAPI and VMware land. 

But first and foremost I want to address the question: "Is there any point in the community working on such a solution, or are one of the bigger companies secretly working on something that would supersede any community effort?" - yes, yes, a thousand times yes to community collaboration!

The topic of CRDs is kind of huge. It's really great to hear your focus is on things like orgs/spaces. From a CAPI perspective, I've been thinking more about representing apps and push as CRDs, and I believe the Eirini team has some thoughts in this area as well. There's a lot of ground to cover clearly.

In terms of things that are in flight now.
  • Keshav kindly shared that networking is looking to provide Route CRDs.
  • Networking is also exploring providing Security Groups as CRDs.
  • CAPI is integrating kpack into CF to provide buildpack staging. This is done by generating kpack CRDs.
Currently these CRDs are being created and owned by the Cloud Controller, which enables us to present backward compatible APIs to our CLI and UI like stratos, while moving the implementation down into controllers fronted by CRDs.  There's an obvious potential to interact with k8s directly in the future, but the current use case is to be used by CC. Except for kpack which is an excellent stand alone tool already :).  

These efforts are great and are allowing us to begin a path towards using existing k8s tooling and projects to provide Cloud Foundry outcomes, but obviously there's a lot further to go.

From VMware's side, over the last couple weeks, there has been an effort to explore what it might look like to use CRDs entirely as a source of truth for *all* CF data, in place of a SQL database, as a learning exercise, not necessarily a desired outcome. The primary goal of that effort was to start the convo that we're having now, and to be able to contribute in a meaningful way.  Note there are no VMware-based plans to dump a fully fledged proposal. We need to start from a premise as a community of understanding how/why/and which resources are valuable as CRDs.

For example when we look at orgs/spaces - we have to wonder if those are even resources we want to represent as CRDs, when k8s already has a namespace construct.

I think we'll need to start some dedicated working document to collaborate in. I had planned on facilitating that after some of the investigation that VMware has wraps up, but I don't think that's a reason to hold off if you or somebody else in the community has thoughts they want to start getting down. CAPI and other teams can contribute to an existing doc if that makes sense. Any other thoughts you'd prefer for next steps?

Looking forward to a continued conversation.

Hi all,

In the spirit of community, I'm going to ask this question outright and in the open - is anyone (*looks at VMware MAPBU*) working on a CRD and accompanying controller for CF on Kubernetes?

Anyone with a non-trivial amount of Cloud Foundry experience knows that whilst the imperative interface of the CF CLI is great for exploratory work, it's far from ideal for production environments. I make a point of telling folks in CF training courses that no human should be using the CLI in production, other than for debugging.

A declarative interface for CF has always been desirable, and its omission is going to become even more stark once running CF on Kubernetes is the norm. We've had cf-mgmt which is close, but involves more steps than is ideal.

It'd be great to have one or more CRDs that represent the state of a Cloud Foundry, and accompanying controllers that converge upon that state. When I talk about state, I mean things like orgs, spaces, service broker registrations, service instances, roles and so on.

Four years ago I started work on a project called cf-converger to diff and converge a Cloud Foundry instance on a state declared in YAML. I got distracted with running a business and doing billable work, so whilst the concept was proven, it never really got to a state of usefulness. Plus, I seemed to spend half my coding time just writing excessively-verbose chained method calls on the official Java CF client :D 

I see such a solution as an inevitability in the Kubernetes-based future. Whilst I'm personally tempted to resurrect the project, it makes very little sense for a company like EngineerBetter to divert resources from billable work to a project that is needed, but can't be monetised.

Are any of the big players working on something similar? Is it something we should all be thinking and talking about? Is there any point in the community working on such a solution, or are one of the bigger companies secretly working on something that would supersede any community effort?

Re: Removing bits-service from cf-deployment

I don’t think that using bits-service with the mentioned ops files will work. In fact support for bits-service is broken since cf-deployment v12.39 (incl. CAPI v1.92, more precisely commit https://github.com/cloudfoundry/cloud_controller_ng/commit/66fb2bd434656e8caa060ff55e6c87a296ab1455 that adds a new method which is not implemented in the Ruby BitsService::Client class).

Wanted to follow up. There's now a doc to start building out our understanding of CRDs here https://docs.google.com/document/d/1mIMH4uEtIJkZjVa5mKWJoIAIeVyM4gVqO-Cx5JtYgtE/edit?usp=sharing

Yes, this is the current approach for the CRDs that Cloud Controller interacts with now. There are also reconciliation loops that we run for these resources analogous to how we've always reconciled CCDB state with Diego.

I think this method has developed organically from our goal of preserving in-place workflows via having the same API surface, allowing cli to function without changes, while trying to consume existing functionality in k8s. I think the longer term goal here is to review that usage and be more intentional about how we expect CRDs to fit into the system as a whole.

It's great that folks are already thinking about this.

Zach, am I correct in thinking that the current approach is the have clients interact with CloudController, have CloudController persist to CCDB as per usual, and then CloudController post stuff to CRDs in the Kube API?

I'd kinda imagined things going the other way around, introducing the CRDs as a new user interface, and have the controllers do the diff and then post/put to CloudController. The intention here would be saving Kubes-native folks (and CI servers!) from having to deal with the imperative interface. I was working on the assumption that all CF concepts would be exposed as CRDs.

From a CAPI perspective, I've been thinking more about representing apps and push as CRDs, and I believe the Eirini team has some thoughts in this area as well.

I'd always dodged this area in cf-converger as it was the most complicated, and the biggest break from the current CF experience :)

For example when we look at orgs/spaces - we have to wonder if those are even resources we want to represent as CRDs, when k8s already has a namespace construct.

I can imagine that the logical concept of orgs may one day map onto distinct Kubernetes namespaces, but I hadn't imagined that orgs would in any way disappear, or not be configurable via the Kubernetes approach.

It'd be great to hear what others think on all of this.

Thanks again for sharing, Keshav and Zach.

Hey Daniel,

Thanks for starting a convo. The timing couldn't be better. I can share some of the thinking going on in both CAPI and VMware land. 

But first and foremost I want to address the question: "Is there any point in the community working on such a solution, or are one of the bigger companies secretly working on something that would supersede any community effort?" - yes, yes, a thousand times yes to community collaboration!

The topic of CRDs is kind of huge. It's really great to hear your focus is on things like orgs/spaces. From a CAPI perspective, I've been thinking more about representing apps and push as CRDs, and I believe the Eirini team has some thoughts in this area as well. There's a lot of ground to cover clearly.

In terms of things that are in flight now.
  • Keshav kindly shared that networking is looking to provide Route CRDs.
  • Networking is also exploring providing Security Groups as CRDs.
  • CAPI is integrating kpack into CF to provide buildpack staging. This is done by generating kpack CRDs.
Currently these CRDs are being created and owned by the Cloud Controller, which enables us to present backward compatible APIs to our CLI and UI like stratos, while moving the implementation down into controllers fronted by CRDs.  There's an obvious potential to interact with k8s directly in the future, but the current use case is to be used by CC. Except for kpack which is an excellent stand alone tool already :).  

These efforts are great and are allowing us to begin a path towards using existing k8s tooling and projects to provide Cloud Foundry outcomes, but obviously there's a lot further to go.

From VMware's side, over the last couple weeks, there has been an effort to explore what it might look like to use CRDs entirely as a source of truth for *all* CF data, in place of a SQL database, as a learning exercise, not necessarily a desired outcome. The primary goal of that effort was to start the convo that we're having now, and to be able to contribute in a meaningful way.  Note there are no VMware-based plans to dump a fully fledged proposal. We need to start from a premise as a community of understanding how/why/and which resources are valuable as CRDs.

For example when we look at orgs/spaces - we have to wonder if those are even resources we want to represent as CRDs, when k8s already has a namespace construct.

I think we'll need to start some dedicated working document to collaborate in. I had planned on facilitating that after some of the investigation that VMware has wraps up, but I don't think that's a reason to hold off if you or somebody else in the community has thoughts they want to start getting down. CAPI and other teams can contribute to an existing doc if that makes sense. Any other thoughts you'd prefer for next steps?

Looking forward to a continued conversation.

The CF-K8s Networking team is currently working on a solution using Route CRDto introduce a “Route” custom resource and have Cloud Controller make/update these directly as part of the `cf map-route` and `cf unmap-route` workflows.

Hi all,

In the spirit of community, I'm going to ask this question outright and in the open - is anyone (*looks at VMware MAPBU*) working on a CRD and accompanying controller for CF on Kubernetes?

Anyone with a non-trivial amount of Cloud Foundry experience knows that whilst the imperative interface of the CF CLI is great for exploratory work, it's far from ideal for production environments. I make a point of telling folks in CF training courses that no human should be using the CLI in production, other than for debugging.

A declarative interface for CF has always been desirable, and its omission is going to become even more stark once running CF on Kubernetes is the norm. We've had cf-mgmt which is close, but involves more steps than is ideal.

It'd be great to have one or more CRDs that represent the state of a Cloud Foundry, and accompanying controllers that converge upon that state. When I talk about state, I mean things like orgs, spaces, service broker registrations, service instances, roles and so on.

Four years ago I started work on a project called cf-converger to diff and converge a Cloud Foundry instance on a state declared in YAML. I got distracted with running a business and doing billable work, so whilst the concept was proven, it never really got to a state of usefulness. Plus, I seemed to spend half my coding time just writing excessively-verbose chained method calls on the official Java CF client :D 

I see such a solution as an inevitability in the Kubernetes-based future. Whilst I'm personally tempted to resurrect the project, it makes very little sense for a company like EngineerBetter to divert resources from billable work to a project that is needed, but can't be monetised.

Are any of the big players working on something similar? Is it something we should all be thinking and talking about? Is there any point in the community working on such a solution, or are one of the bigger companies secretly working on something that would supersede any community effort?

Release Integration No Longer Testing CATs on BOSH Lite

Dave Walter <dwalter@...>
 

Hi All,

The CF Release Integration team wanted to give y'all a heads up that we have decided to stop running CATs on our BOSH lite CI environment due to its flakey nature and the time wasted debugging.

Going forward, we are only validating new changes on BOSH lite by running smoke-tests. Please feel free to reach out if you have any questions.

Regards,
Dave

On the Quarks team we’ve been working with CRDs for some time and we’d like to socialize with other teams doing similar work.

Maybe we could setup a slack channel specific to this?

Hi, all,


After four years (almost) at the helm of CF Extensions, I am announcing that I am stepping down as the lead. I believe the time is ripe as CF is transitioning to new waters and since I am less involved with the projects these days, it's time for someone else to take over and steer us to greener pastures.


I took on the CF Extensions lead role when none existed at the end of 2016. I remember, like yesterday, when Sam asked me to start an Extensions PMC for Cloud Foundry during our summit in Frankfurt. Since then, we have added close to 20 extensions projects with many having graduated and a few fading away. Exactly what we envisioned, so for that I am happy and thankful to your participation and contributions.


Overall, I feel positive and hopeful that better days are ahead for CF and this community. You have a vibrant group of contributors and excellent committed leadership in the Cloud Foundry Foundation. I will miss the kindness, brersity, and excellence that this community has always strived to achieve and uphold.


That said, I will not be far away. I am still involved in OSS for IBM and will be happy to help in any way I can, when you need me. Swarna will be sending a separate email to look for volunteers and elect a leader.


-----
With that, my little TBT present to you are the following curated photographs I have taken of you during our time together at the many CF Summits, CF days, and events all across the world.


From some of the first CF Summit NA: Santa Clara in
2015-16-17; to CF Summit Asia in Shanghai 2016; to CF Days: Pune, India 2016, Misk, Belarus 2016, London 2018, NY 2018, and Copenhagen 2018; to CF Summit Europe: Frankfurt 2016, Basel 2017-2018, Den Haag 2019; and most recently CF Summit NA: Boston 2018 and Philadelphia 2019.


You've often seen me with a camera in hand shooting away. So here's the main reason, to allow us to remember, to look back, and to reminisce a bit on the great memories, fun times, and lasting friendships we have forged in this community. With that, here are two curated sets of what I believe are my most memorable and best 150 photographs of Cloud Foundry community events and members. Hope you like:

PS: While I took care to select the best photos, I can fully understand if there is a photo of you, or that you are in a photo, that you do not like or rather I not share. Please let me know and I will remove ASAP.
Also, to respect the privacy of all, I ask you to get permissions before re-sharing, of course, if the photograph includes someone other than yourself. In my experience most people agree, so just ask.

The CF-K8s Networking team is currently working on a solution using Route CRDto introduce a “Route” custom resource and have Cloud Controller make/update these directly as part of the `cf map-route` and `cf unmap-route` workflows. Happy to discuss this further in our Cloud-Foundry Slack- #networking group. Regards, Keshav Sharma Product Manager | CF-K8s-Networking VMware

Hi all,

In the spirit of community, I'm going to ask this question outright and in the open - is anyone (*looks at VMware MAPBU*) working on a CRD and accompanying controller for CF on Kubernetes?

Anyone with a non-trivial amount of Cloud Foundry experience knows that whilst the imperative interface of the CF CLI is great for exploratory work, it's far from ideal for production environments. I make a point of telling folks in CF training courses that no human should be using the CLI in production, other than for debugging.

A declarative interface for CF has always been desirable, and its omission is going to become even more stark once running CF on Kubernetes is the norm. We've had cf-mgmt which is close, but involves more steps than is ideal.

It'd be great to have one or more CRDs that represent the state of a Cloud Foundry, and accompanying controllers that converge upon that state. When I talk about state, I mean things like orgs, spaces, service broker registrations, service instances, roles and so on.

Four years ago I started work on a project called cf-converger to diff and converge a Cloud Foundry instance on a state declared in YAML. I got distracted with running a business and doing billable work, so whilst the concept was proven, it never really got to a state of usefulness. Plus, I seemed to spend half my coding time just writing excessively-verbose chained method calls on the official Java CF client :D 

I see such a solution as an inevitability in the Kubernetes-based future. Whilst I'm personally tempted to resurrect the project, it makes very little sense for a company like EngineerBetter to divert resources from billable work to a project that is needed, but can't be monetised.

Are any of the big players working on something similar? Is it something we should all be thinking and talking about? Is there any point in the community working on such a solution, or are one of the bigger companies secretly working on something that would supersede any community effort?

Re: Stepping down as CF Extension PMC lead and a small TBT present

Krannich, Bernd
 

Hi Dr. Max,

 

Sad to see you stepping down as Extensions PMC lead. Thank you very much for all you have done for the CF community!

 

I’m hopeful that one day in the (hopefully not too distant) future we’ll again bump into each other at one of the great open source conferences somewhere in the world so that we can hang out together.

 

All the best,

Bernd

Your presence is invaluable to our community.  I can only name a few hats you wore over the years, but all the roles you've taken on helped us immensely in shaping our community! 

  • hosting Community Call 
  • leading the Extensions-PMC 
  • supporting us immensely for Hackathons at Summit
  • advocating Cloud Foundry technology in our community and within the broader open source community 
  • representing our community everywhere
  • being a true Cloud Foundry Ambassador!
  • capturing all the amazing memories and sharing the pictures with us
  • ...and so many more.

Hi, all,


After four years (almost) at the helm of CF Extensions, I am announcing that I am stepping down as the lead. I believe the time is ripe as CF is transitioning to new waters and since I am less involved with the projects these days, it's time for someone else to take over and steer us to greener pastures.


I took on the CF Extensions lead role when none existed at the end of 2016. I remember, like yesterday, when Sam asked me to start an Extensions PMC for Cloud Foundry during our summit in Frankfurt. Since then, we have added close to 20 extensions projects with many having graduated and a few fading away. Exactly what we envisioned, so for that I am happy and thankful to your participation and contributions.


Overall, I feel positive and hopeful that better days are ahead for CF and this community. You have a vibrant group of contributors and excellent committed leadership in the Cloud Foundry Foundation. I will miss the kindness, brersity, and excellence that this community has always strived to achieve and uphold.


That said, I will not be far away. I am still involved in OSS for IBM and will be happy to help in any way I can, when you need me. Swarna will be sending a separate email to look for volunteers and elect a leader.

With that, my little TBT present to you are the following curated photographs I have taken of you during our time together at the many CF Summits, CF days, and events all across the world.


From some of the first CF Summit NA: Santa Clara in
2015-16-17; to CF Summit Asia in Shanghai 2016; to CF Days: Pune, India 2016, Misk, Belarus 2016, London 2018, NY 2018, and Copenhagen 2018; to CF Summit Europe: Frankfurt 2016, Basel 2017-2018, Den Haag 2019; and most recently CF Summit NA: Boston 2018 and Philadelphia 2019.


You've often seen me with a camera in hand shooting away. So here's the main reason, to allow us to remember, to look back, and to reminisce a bit on the great memories, fun times, and lasting friendships we have forged in this community. With that, here are two curated sets of what I believe are my most memorable and best 150 photographs of Cloud Foundry community events and members. Hope you like:

PS: While I took care to select the best photos, I can fully understand if there is a photo of you, or that you are in a photo, that you do not like or rather I not share. Please let me know and I will remove ASAP.
Also, to respect the privacy of all, I ask you to get permissions before re-sharing, of course, if the photograph includes someone other than yourself. In my experience most people agree, so just ask.
