Re: CF CLI: how do you use `no-start` with `cf push`
Dr Nic Williams <drnicwilliams@...>
I use no-start because ‘cf push’ doesn’t have flags to set env vars/service bindings.
If the response to that is “use manifest.yml” then perhaps get rid off all the push flags and force ppl to use manifest.yml. As it stands now, we can cf push most attributes of the manifest.yml, except env vars and service bindings.

i'd like to ask a clarifying question. it sounds like most of these use-cases are "set up some environment for the app". this implies to me that these workflows are for new apps and not for updating existing ones. does that sound right? are their use-cases
for "no-start" when updating an app?

Removing varz support for Routing components
Shubha Anjur Tupil
Hi, To walk down memory lane a bit, the varz endpoints were replaced with the firehose more than two years ago. The relevant threads are - https://lists.cloudfoundry.org/g/cf-dev/message/4401?p=,,,20,0,0,0::relevance,,varz,20,2,0,6333224 - https://lists.cloudfoundry.org/g/cf-dev/message/5100?p=,,,20,0,0,0::relevance,,varz,20,2,0,6333422 In the interest of code maintenance for the routing components we are considering removing the code to support the varz endpoints. All users should have transitioned to using the firehose nozzle. Let us know if and why this might be a problem. Regards, Shubha

Re: CF CLI: how do you use `no-start` with `cf push`
Abby Chau
Hey Bernd, Zach can speak more to this but, I believe, the CC v3 API has been stable for some time, with v3.27. The v3 prefixed CF CLI commands are relatively lesser known so apologies if it's been relatively unclear. All the CF CLI v3 prefixed commands are all still considered experimental (the CLI commands such as `cf v3-push`, `cf v3-app`, `cf v3-set-health-check`, `cf v3-droplets`, etc) . A few reasons for this are that the CF CLI team wanted to garner feedback about them from users, and we wanted the freedom to change the commands (output, etc) based on user feedback. An example of this is the `cf v3-app` command, which we will be changing soon based on user feedback. (There is a survey out currently about the UX). Starting with the `cf v3-app` command, (which we will remove the experimental status for soon, and which the current `cf app` command will default to using for users on CC API 3.27. or higher) the CF CLI team have embarked on a concerted effort to remove experimental status for all the other v3 prefixed commands. We realise this may have an impact on users, and we want to mitigate for this as much as possible - we are doing so by asking the community for feedback, and updating them as much as possible regarding our current efforts. After we release the work for the `cf v3-app`, we will be looking at other CF CLI v3 prefixed commands to remove the experimental status for - again we are keen on making sure impact is minimal for users whilst simultaneously trying to make sure all the benefits of the v3 CC API functionality is fully realised as intended. I hope this makes sense, please do not hesitate to reach out if you have any questions or feedback. We will be communicating with the community each step of the way. Best, Abby

Re: CF CLI: how do you use `no-start` with `cf push`
Krannich, Bernd <bernd.krannich@...>
Hi Abby, Zach,
I don’t think we have looked into v3 commands in too much detail. Please forgive my ignorance in this topic, are the v3 commands already considered a stable API so that I could check if people can replace their existing “--no-start” scenarios with it?
> this implies to me that these workflows are for new apps and not for updating existing ones. IIRC, some of those workflows are done as part of blue-/green-updates. I am not sure that people would completely delete their currently inactive app completely, or if they would just keep updating the inactive app and then switch over to it.
Thanks in advance, Bernd

We have multiple foundries in our org and occasionally we would want to push an app in the stopped state to a pool for DR purposes (active/active across foundries is always desirable but simply not always practical for older applications transitioning to CF).

Re: CF CLI: how do you use `no-start` with `cf push`
Abby Chau
Hey Bernd and Julian, Many thanks for your responses. Wondering if you folks have tried using the `v3-create-app` command as Mike has pointed out (and Zach elsewhere). The command is basically the equivalent of `cf push test --no-start` in that it creates an app, leaves it in a `stopped` state, and users can then apply configurations, bind services, set-groups, enable ssh, etc. This command appears to be a workaround for your use cases, but please let us know if that's incorrect. Best, Abby

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,

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.

We mostly use it to do things to an application before starting it that cannot be done in a manifest. For example, setting computed environment variables, or binding services that need service-parameters. I think "--no-start" can be removed and we could use v3-create-app instead. Mike

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. -Dieu Cao
