[cf-abacus] Usage Sampler proposal

Hristo Iliev

#8269

Hi all,

Abacus team is ready to start the next big chunk of work. We want to remove the time-based metrics we now use to integrate with Cloud Foundry's app & service events and replace them with sampling.

Why?

Time-based metrics are complex, costly in terms of CPU and storage space. Clients have to renew time-based usage, which requires persistence on their side. We see tham as unreliable and error-prone.

How?

We are proposing a new Sampler component that will expose REST API for continuous events.

More info can be found in this document:

https://docs.google.com/document/d/1I7yCsojhpif4_BobZ2FvnoehEoVI5f6G6kfBiS_uRKU/edit?usp=sharing

Your feedback is highly appreciated.

Regards,

Hristo Iliev

Look at it from a corporation's view, they don't want to trust more repositories than the formal open source repos having a support of a community and it's secure since the community has it under control, instead of my own public repo that I can mess it up anytime.

I wouldn't expect anyone to trust a random repo from the internet. They'd want to host their own Tomcat config on a server they control, like an app they push to their platform using the Staticfile buildpack.

Anyway, I probably do not fully understand your use case and that's OK. I just wanted to suggest this other option in case it might work for you.

Dan

That's my whole point, it can be a parameter exposed in the formal code base which everyone has trust on.

Apps/microservices that have long request processing times.

#8266

Hi,

According to https://docs.cloudfoundry.org/devguide/deploy-apps/prepare-to-deploy.html#moving-apps an app instance has only 10 seconds to finish processing a request before being killed off.

I have an app that does document rendition generation and it can take upwards of 10 minutes for long documents.

Is the 10 seconds grace period configurable?

Thanks,

Not sure what you mean. It doesn't require that you fork the buildpack. You just need to host your Tomcat config somewhere. That's cause the buildpack will need to download it, since it's not part of the JBP. The easiest way is to push your config w/the Staticfile buildpack. Then you can use `cf set-env` and tell the JBP to use your external config bundle from your Staticfile app. You could post the config elsewhere too, like S3 or any other HTTP server.

We can argue that this is kind of needed for CF services, due to the nature of using JWT token in header; if you want to put something convincing in the pull-request comment ;)

Have you tried the support that's already in the Java buildpack for customizing Tomcat configuration?

https://github.com/cloudfoundry/java-buildpack/blob/master/docs/container-tomcat.md#external-tomcat-configuration

This lets you configure all aspects of Tomcat's config, not just the header size.

CF CLI v6.39.0 Released Today

Abby Chau

#8253

Hey everyone,

The CF CLI team released cf CLI v6.39.0 today; please see release notes for full details.

Highlights include:

Refactors (rewrites):

Buildpacks-related commands

In order to prepare for the buildpack - stack association feature (see below), the CLI embarked on a rewrite (refactor) of a subset of buildpacks-related (create-buildpack, update-buildpack, and rename-buildpack) commands. User-facing changes include promoting consistency, improving error messages, and enhancing the UX to provide additional information.

Create-org command

We also refactored the `create-org` command to prepare for work on fixing an existing issue with creating orgs whilst logged with client credentials. (see below)

Buildpacks association with stacks feature

In order to help with the transition to cflinuxsf3 in April 2019, stack association with buildpack is introduced in this release. Buildpacks can now have the same name, as long as they are associated with a unique stack. Several buildpacks-related commands (update-buildpack, rename-buildpack, and delete-buildpack now take a `-s` flag to disambiguate buildpacks that have the same name.

Services-related features

`cf bind-service` and `cf unbind-service` now supports asynchronous operations
`cf share-service` and `cf unshare-service` are no longer experimental features

Enhancements and bug fixes

`cf auth` now supports the `--origin` option to log into different identity providers
`cf start`, `cf restart`, `cf restage` have been updated to use the new v3 `cf app` display
fixes an issue with internal domains as your default domain: if you are using internal domains, and the internal domain is the first domain created, the CLI will ignore the internal domain and when you run `cf push` will choose the next non-internal domain to map your app
bug fix for a `brew install cf-cli` issue for users using the unreleased master branch of Homebrew
bug fix for users logging in with client credentials, now `create-org` properly assigns the user role to the client id

Contributors: An Yu, Sebastian Vidrio, Anande Gaitonde, Thomas Viehman, Alex Zhao, Abby Chau, Spencer Hawley, Renee Chu, Nick Guerette, Ryan Tang, William Murphy

Special Guests: Buildpacks team (for help with the buildpack-stack association feature), SAPI London team (for pull requests and the async operation work), SAP and UAA Team (for help with the `cf auth` `--origin` work)

Feedback

Please contact us on the #cli channel on Cloud Foundry Slack. Alternatively, respond directly to this email.

Best,

Abby and the CLI team

Hi Umesh,

I did a test the cfdev plugin on the windows 10 pro on windows azure with Standard D4s v3, it works.

Details steps:

Create one “Standard D4s v3” windows 10 pro VM on azure.
Enable the hyper-v follow this document https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v
Download& install cf-cli v6.28.0 => v6.38.0 from https://github.com/cloudfoundry/cli/releases
install the plugin cf install-plugin cfdev
run the cf dev start.
Login into the cf using : “cf login -a https://api.dev.cfdev.sh --skip-ssl-validation”
Clone one sample application https://github.com/bingosummer/2048
cf push

the app start up correctly.

BTW, I also tested the windows server 2016, it does not work for now, that’s due to the hyper-v detection logic does not cover the windows server 2016.

Hi Umesh,

And also I have another way to do the cf development, deploy the cloud foundry on one box:

https://github.com/virtualcloudfoundry/cf-azure-deployment/tree/master/cf-lite

here’s the sample scripts to do the deployment:

terraform apply -var prefix="cf-blabla" -var subscription_id="<your subsciption id>" -var client_id="<your client id>" -var client_secret="<your client secret>" -var tenant_id="<your tenant id>" -var ssh_user_username="cfcf" -var ssh_public_key_filename="./ssh_key.pub" -var auto_deploy_bosh="enabled" -var auto_deploy_cf="enabled" -var location="eastasia"

after run this, you would get one dev box, and one box, and one cf box.

You can login into the dev box to do the cf push and so on. (using cfcf and the ssh_key.priv to connect to it)

it’s not an official release, but normally I use it for cf feature development.

Feel free to shoot me one email if you have problem using it.

As Frederic mentioned earlier in the chain - this tool is intended to run on a local machine, not an Azure VM. However, in theory it should work on an Azure VM if you configure the VM with 4 cores and a generous amount of RAM (64 GB +) and also configure it to use nested VMs (https://docs.microsoft.com/en-us/azure/virtual-machines/windows/nested-virtualization) so it can use native hypervisors.

We have not seen this setup work on our team - but you may be able to get it to work. Let us know.

However, in theory it should work on an Azure VM if you configure the VM with 4 cores and a generous amount of RAM (64 GB +) and also configure it to use nested VMs (https://docs.microsoft.com/en-us/azure/virtual-machines/windows/nested-virtualization) so it can use native hypervisors.

We have not seen this setup work on our team - but you may be able to get it to work. Let us know.

Hi Umesh,

And also I have another way to do the cf development, deploy the cloud foundry on one box:

https://github.com/virtualcloudfoundry/cf-azure-deployment/tree/master/cf-lite

here’s the sample scripts to do the deployment:

after run this, you would get one dev box, and one box, and one cf box.

You can login into the dev box to do the cf push and so on. (using cfcf and the ssh_key.priv to connect to it)

it’s not an official release, but normally I use it for cf feature development.

Feel free to shoot me one email if you have problem using it.

Thanks,

Andy

Hi Umesh,

Just got message from cf dev team, the cfdev plugin only available on windows 10 and macos for now.

And here’s the tracking issue for the support on Linux box: https://github.com/cloudfoundry-incubator/cfdev/issues/18

So maybe you should use a windows 10 or windows server 2016 vm to use the cfdev 😊

I also will try it later. Will post the result on this thread.

Thanks

Andy

Dear Scott,

Thanks a lot for prompt reply !!!

I tried running the commands however I didn't get the plugin from CF community.

I have below Azure VM with 16GB RAM.

[root@GBAZUKSL025 ~]# uname -a
Linux GBAZUKSL025 3.10.0-862.9.1.el7.x86_64 #1 SMP Wed Jun 27 04:30:39 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux

I believe, it will not work till you make some tweaking in PFC Dev as per specific platform.

Please let me know if you have any other troubleshooting steps to follow.

Regards,

Umesh Kumar

Hi Umesh,

Im the PM for CF Dev - you are using the legacy PCF Dev plugin - please use the latest version the new CF Dev that uses native hypervisors instead of virtual box for virtualization

You can get this version if you uninstall the legacy pcf dev plugin

`cf uninstall-plugin pcfdev`

and then install the latest version of cf dev

`cf install-plugin cfdev`
