(action requested) Changing CF App Display

Abby Chau
 

Hello cf-dev,

In order to provide a better user experience, the Cloud Foundry CLI team is considering changing the   cf app app-name  key-value and table display information. Towards this effort, we are asking the community to complete a short survey. 

Actions: Please fill out this short survey [1] to help us understand how you use the cf app app-name command display, and your thoughts on changing the display to default to the V3-app version of the command. The survey will close by end of day, June 15th. 

Thanks in advance for your time and participation.

Best,

Abby Chau

Hi Ronak,

We don't currently have that prioritised currently for the CF CLI, but please create a github issue for visibility and future consideration.

Thanks,

Abby

Hi Abby,

Going forward is there something on roadmap to use ops files for cf CLI too, like we do for Bosh CLI or yaml patch?

Use case can be CI/CD pipelines where part of manifest can be injected for different environment.

Thanks

Hi Benjamin,

Thanks for reaching out; we will update the documentation for clarification. The partial value use case, for example, is a manifest.yml with the following:

- route: ((host)).example.com

and a variable.yml file which invokes the value by passing in the hostname:

host: test

When you push with the manifest and variable file, the route test.example.com will be created. Hope that makes sense.

It’s quite unclear what is meant by “partial values”, and the example doesn’t bring an illustration to this. Indeed, correct me if I’m wrong but this second example looks the same as the first one, because using --vars-file <(cat secrets.yml) should be quite the same as writing --vars-file secrets.yml.

Maybe “partial values” was a way to say that multiple --vars-file arguments can be used?

Hi all,

The CF CLI team released cf CLI v6.37.0; please see release notes for full details. 

Highlights include:
  • Variable substitution - (replaces inheritance) which allows app developers to create app manifests with values shared across all applicable environments in combination with references to environment-specific differences defined in separate files
  • Now the CLI reads username and password from environment variables
  • If you are using a API version older than 2.69.0, a warning displays asking you to update your API version - as the CLI no longer supports versions older than 2.69.0
Bug Fixes:
  • Fixes a bug whereby X-Cf-Warnings were not being unescaped when displayed to user
  • When using CF_TRACE=1, passwords are now sanitized

Let us know if you have any comments or feedback, thanks!

Re: Deprecation Notice: bosh-hm-forwarder is moving

Mike Youngstrom
 

Thanks Joseph,

Perhaps just sending everything would be fine as long as the deployment were added as a tag to the metric or something.  I'll keep thinking about it, look at the code now that it is available, and create an issue in the release repository if I want to discuss it further before putting together any kind of PR or anything.

Thanks,
Mike

Bosh system metrics can not filter based on deployment (or any other criteria).

We haven't heard about this use case yet but it does sound interesting. If filtering were an option, would you have one deployment of CF with no filter enabled to receive metrics from deployments for non-cf releases (e.g. postgres, redis, et cetera)?

In terms of security, there are no deployment-level permissions on the forwarder client: any consumer that successfully connects to the bosh-system-metrics-server has access to the entire stream. Filtering could occur on either end (director or forwarder), but either way, all metrics will be accessible to any deployment.

It would be relatively straight-forward to fork and add a deployment filter option to the code (1).

NOTICE: [php-buildpack] Default PHP version will change from 5.6.x to 7.2.x after 2018-07-02

Scott Sisil
 

The default version of PHP will be updated to 7.2.x in the first release after 2018-07-02.


Per the PHP supported versions website, all support for the 5.6.x series of releases will end on 2018-12-31, roughly four years after the initial release[1]. We are giving users a 30 day notice before we change the default version of PHP to 7.2.x. We will continue to support 5.6.x until the end of the year, but if you are still using PHP 5.6.x, we strongly encourage you to upgrade to a more recent, fully supported version of PHP.

Hi Adam,

 

Congrats, excited to see this as an incubation proposal, following the Eirini example directly in the Runtime PMC. It is great to see these pieces of technology moving into the core of CF right away.

 

I left a few smaller cosmetic feedbacks inside the docs you shared.

Oratos Incubation Proposal #loggregator

Adam Hevenor
 

As many of you know, the Loggregator team has been experimenting with containerizing the Loggregator and Log cache components for use in a K8s context. I posted about these efforts previously[1], and we would like to officially nominate these efforts for incubation within the Runtime PMC (we have also considered extensions - but this would mean twice as many meetings for me ;-) ). We feel that assigning a specific team to this effort is worthwhile to formalize the efforts around product research and design and also want better communicate our intentions to the CF community to gather feedback. Additionally we have identified a first up feature proposal[2] to focus on. 

Please review this proposal and FAQ[3] and provide your feedback and comments here or in the document.

Hi Adam,

Is it possible to tell bosh-system-metrics to only forward metrics from certain deployments to loggregator?  We deploy multiple CFs on a single bosh and would like to only forward metrics related to a given CF onto that CF's loggregator stream.

rep fd keep increasing until 'too many open files' and cell in bad status

Qiu Jie QJ Li <liqiujie@...>
 

Hi, CF developers
We met a problem that rep fd keep increasing until 'too many open files'.

Our cloudfoundry env was built on kubenetes cluster, it had 3 VMs under it.  1 for diego-cell (4core * 16G) and 2 for others.   When we did stress test, we used 10+ threads to push/start/stop/../delete apps continuously with 10s thinktime between each step. It began with 0 errors, but always ended with cell in bad status hours later.    App stage failed with 'can't communicate with compatible cells' and 'too many open files' in rep.stdout.log . We began to monitor the # of files under /proc/<rep-pid>/fd due to the 'too many open files' hint and noticed that the # of files was steady at first, then from a point, it kept increasing, even after the push app test was completely stopped, the increasing file number seems like the cause of 'too many open files' and most likely would cause the node(VM) unreachable in the end.

Why would this fd keep increasing? Was there some leak or something couldn't be released?  

I had opened an issue in rep repository https://github.com/cloudfoundry/rep/issues/21with more details. Please let us know what extra detailed info you need to know.

Thanks a lot.

Qiu Jie (Sophy) Li

Re: Is anyone successfully using IPSec along with Windows Server 2016 (1709)?

Pivotal has a commercial offering providing IPSec integration for the Windows stack. As a first stab, perhaps our public docs may contain some configuration clues for you?

We're testing out the new Windows version and everything appears to be working correctly with the exception of traffic from the routers to the containers via the NAT on the Windows cells.  The IPSec session is working between the router and the Windows host itself but there is just no response when connecting to a mapped port inside a container.  For example:

router (10.10.10.10) -> windows2016-cell (10.10.10.11) - works fine for any open port (rep, consul etc.) on the cell itself
router (10.10.10.10) -> windows2016-cell (10.10.10.11) -> container (172.30.0.10) - no response to the external port for either HTTP or SSH (for example, 40000 and 40001)

As soon as we turn off IPSec the traffic works just fine and we can access the app via the gorouter and cf ssh is connecting successfully.  The error message from the router looks like this:

curl: (7) Failed to connect to 10.10.10.11 port 40000: Connection refused

Please let me know if you were able to get this working correctly.
