Re: CF CLI: how do you use `no-start` with `cf push`

Hjortshoj, Julian <Julian.Hjortshoj@...>
 

+1 to that last use case.  In particular, if a service requires bind configuration, then it's not possible to put the binding in an app manifest (because manifests don't support service binding configuration) so it is very helpful to keep your app from starting until the service is bound.

Adding the ability to specify bind configuration in an application manifest might be a reasonable mitigation if --no-start were to disappear.

HTH,

Hi Abby,

 

Thank you very much for reaching out. Indeed, we are frequent users of the `no-start` flag. A couple of use cases:

 

  • After a `cf ssh-enable APP_NAME`, you’ll need to restart your app to be able to SSH in. To prevent starting the app twice in that process, people do a `cf push --no-start` and then an explicit `cf start APP_NAME` afterwards.
  • The same applies for changes of security groups which also require an app restart.
  • Lastly, and maybe most importantly, people use `no-start` for pushing an app to which they want to bind services. They push the app with “no-start”, “cf create-service” their services, “cf bind-service” them to the app, and only then start the app.

 

So, I guess in summary, for all operations changing the app environment, doing those changes with the app not yet started is a common use case for us.

 

Regards,

Bernd

Hi everyone,

 

The CF CLI is soliciting feedback on how you use the `no-start` flag: 

  • what are your specific use cases? 
  • if the flag was no longer available, how might that affect you? (Would you strongly object to such a change, and why?) would you have a sensible workaround?

Note: The CF CLI team is currently working on updating the `cf v3-push` command to use the server side manifest work we've completed (with the Capi team), and to update the command such that it has as much feature parity with the current `cf-push` as possible. The eventual goal is to make the `cf push` command default to the enhanced v3-push command for users (on cc api 3.27 or higher). Since there is more granular control options in v3, `no-start` is a more nebulous flag.

Hi Lee,

Have you seen the new variable substitution feature for manifests?  It might really help your use-case.

Hi, 

We use it when setting env vars that we don't want to commit. Or when committing then would harm the reuse of our code by others.

UAA.yaml envvar substitution

Szerdahelyi, Andras (GE Digital)
 

Hi cf-dev,

i am trying to bootstrap UAA 4.6.1 with an admin user password from the environment. i tried providing the entire scim.users array item and just the password in the pipe-delimited string in said array item, with zero success.

when a complete scim.users item is coming from an envvar ( - ${ADMIN_USER} ), i get a “password cannot be empty” exception and uaa fails to deploy in the container. When i place only the password token ( - admin|${ADMIN_PASSWORD}|... ) i simply can not authenticate with $ADMIN_PASSWORD.

hardcoding an scim.users value works without a problem.

my question then would be this: is envvar substitution allowed for an array item ( - $ITEM ) and/or is envvar substitution allowed/enabled in a string in an array item ( - foo..${BAR} ) ?

thanks,
Andras

Hello all,

Pivotal is nominating Josh Collins for the Release Integration Project Lead in the Application Runtime PMC.  He is currently serving as Interim Project Lead for the Release Integration team.

Any other nominations should be sent to me/in reply by end of day July 3rd, 2018.

Josh was previously the director of product management for a personalized products company and subsequently he managed the A/B testing and optimization efforts for a B2C career development company. Early in his career, Josh worked with a team of three to design and launch the flagship product of what is now a successful company in the backup and disaster recovery space. 

In a previous life, Josh worked for the Berkeley Unified School District as a middle-school teacher and supplemented his income selling foraged wild mushrooms to local restaurants in Berkeley and Oakland. While working as a teacher he ran the school's computer lab and began his journey into networking, graphic design,  web development and beyond. His early successes moonlighting on tech gigs changed his trajectory and ultimately leading to his current employment at  Pivotal.

Josh joined Pivotal R&D in March 2017.

Josh holds a BA in Art from the University of California, Santa Cruz and an MA in Education from University Washington Seattle.

Action Required: Deprecating the built-in garden aufs filesystem driver ("garden-shed")

Julz Friedman
 

Hi cf-developnauts!

I wanted to quickly remind y'all, and seek any remaining feedback, about our plans to deprecate the garden-shed filesystem driver in an upcoming garden release. 

We previously communicated about this here [0], the tl;dr is we have a new filesystem driver implementation, named grootfs, which has been running in production for a while now. At the start of the year we made this the default in garden [1], with an opt-out property to temporarily re-enable the old implementation, in case of problems. It's now coming up on 6 months later.

As far as we know - and this is where you come in! - all remaining bugs, issues and blockers requiring people to opt out of the new driver are resolved, and we are therefore planning to remove the deprecated garden-shed driver, and corresponding config option, in an upcoming garden release. 

ACTION REQUIRED: If you were opting-out of grootfs for any reason, please urgently try again and report any bugs or blockers to us (via GitHub issues, #garden slack, or Tracker) so we can fix them! As of right now we believe everyone is fine for us to delete garden-shed, and we plan to do that soon unless we hear otherwise!

Thanks!
Julz, on behalf of the gardenandgroot team,

Re: (action requested) Changing CF App Display

Abby Chau
 

Hi all,

We've analyzed the `cf app` survey results; thanks again to those who responded. Here's our findings and actions steps:

Based on your feedback, we have decided to change `cf app` to default to the v3 app endpoint:
  • what this means is that for users on CC API 3.27.0 or higher, the `cf app app-name` display will change in an upcoming CF CLI release 
  • for users on CC API 3.27.0 or lower, you will continue to see the current `cf app app-name` display; you will not see the new v3 display unless you upgrade to CC API 3.27.0 or higher (and you have the latest version of the CF CLI)
Survey Results

Please see the image below for results of the survey. Only 6.3% of respondents said they would strongly object to changing the current `cf app app-name` display to default to the v3 app endpoint. 

Next Steps:
  • the v3 app endpoint treats processes as a first class citizen, and as such we want to display this in the most user-friendly way possible. As such, the CLI team is soliciting feedback on changing the UX design of the `cf app appname` to take advantage of v3 capabilities: Please complete this very short survey if you want to vote on the new UX. Voting ends on Tuesday, June . 26th.

Querying across microservices in CF

Pierce Lamb <richard.pierce.lamb@...>
 

I've found that while microservices tend to increase dev productivity by allowing devs to work independently, they also tend lead devs into having independent state across microservices; e.g. each microservice has it's own database

In theory, then, a query across microservices would be challenging. One could encounter data interdependence issues across microservices. Further, querying across microservices using joins and aggregations could require complex application level code to realize.

Does anyone encounter problems with querying across microservices in CF today? And if so how do they solve these problems?

Due to lack of popular demand, we plan to move https://github.com/cloudfoundry-incubator/cephfs-bosh-release into the cloudfoundry-attic org, unhook it from our CI pipelines, and cease further maintenance.  If you have been secretly using this software, please contact us in the next week by replying to this email or finding us on the #persi channel on https://cloudfoundry.slack.com to let us know your use cases.  Unless we’ve heard from someone in the next two weeks, we’ll move it to the attic.

Thanks much,
