Issues with offline ruby_buildpack, disconnected CF, and gems from Git

Josh Ghiloni
 

Hi all,

I’m currently working on a project where I have my gem source in our local git enterprise server, and I need to push an app that uses it to an instance of CF (v208) that is disconnected from the internet. The app has in its Gemfile a reference to that gem like this:

```
gem 'mygem', :git => 'https://github.myco.com/common/mygem.git'
```

When I run

```
bundle install
bundle package
```

That gem never shows up in my `vendor/cache` directory. However, if I use `bundle package --all`, it shows up in my `vendor/cache` directory as `vendor/cache/mygem-0.0.1-d1c2237f1ebca`. Unfortunately, when I `cf push`, the result is the same in both cases: my ruby app fails to find the require. I’m using the ruby buildpack v1.3, for what it’s worth. Also of note, this does run locally.

Is there something I can do to git ruby to recognize that this gem exists? I’m still rather new to Ruby and don’t fully understand the intricacies.

Java Buildpack v3.1

Christopher Frost
 

I'm pleased to announce the release of the java-buildpack, version 3.1. This
release was focused on new monitoring frameworks and the Memory Calculator.
The Memory Calculator removes the need to restage an application after
scaling it's allocated memory. It has the following highlights:


- Dynatrace monitoring framework support. (via Stu Charlton
<https://github.com/cloudfoundry/java-buildpack/pull/187>)
- Introscope monitoring framework support.
- Memory calculator (via Mike Youngstrom, df007
<https://github.com/cloudfoundry/java-buildpack/issues/175>)
- Improved tar downloader (via Claude Devarenne
<https://github.com/cloudfoundry/java-buildpack/pull/195>)
- Improved OS detection (via Christopher Umbel
<https://github.com/cloudfoundry/java-buildpack/pull/185>)

For a more detailed look at the changes in 3.1, please take a look at
the commit
log <https://github.com/cloudfoundry/java-buildpack/compare/v3.0...v3.1>.
Packaged versions of the buildpack, suitable for use with create-buildpack

Custom build pack [ failed to install WineHQ]

Balaramaraju JLSP <balaramaraju@...>
 

Hi All,

I am trying to create a custom build pack. To create a stack like WineHQ
with some VS2010 C++ Runtime to run windows native services.

BuildPack :-

--enable-win64#cd tools
#echo yes |./wineinstallecho "Update" echo "Load Custom Frameworks"echo "
Done"

but it failing with
-----> Downloaded app package (8.0K)
Cloning into '/tmp/buildpacks/WineHQ-BuildPack'...
Install WineHQ
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission

Re: Soliciting feedback on a UX change for route services

Guillaume Berche
 

+1 for binding to a specific route (for all apps) instead of binding for
all routes of an app. One use-case that this will enable is
content-transformation service routers to only be applied on some specific
routes in order to be able measure their performance/latency impact before
extending them on other routes.

+1 for still being able to stack up multiple route services for a given
route (e.g. SSO, caching, and analytics)

This change would also mean that route services would not need to be
bindable, simplifying service development, as applications are not expected
to need credentials to contact the route service directly and CF doesn't
need to know the application in order to make the forwarding decision.

Shanon, can you please clarify that route services may still be bindeable
when this makes sense ?

For example, it might be useful for the apps bound with a router service to
be able to contact the router-service to send some control flow (e.g. for
the caching scenario to request a cache invalidation through HTCP requests
used in wikimedia https://wikitech.wikimedia.org/wiki/Multicast_HTCP_purging
<https://www.google.com/url?q=https%3A%2F%2Fwikitech.wikimedia.org%2Fwiki%2FMulticast_HTCP_purging&sa=D&sntz=1&usg=AFQjCNGsGyNfYqsIugumSD-8L2tcjm4bXQ>
). In this case, the router services would be bound to apps that need to
control it.

BTW, is there available updates on the router services model (i.e. route
service sending traffic back to the router, vs route services being exposed
to the app registry to send traffic to the app directly) ? Dieu mentionned
at the summit some pending discussions with Matt Stine around this topic
(and likely a service discovery / registry being exposed to route services
and apps), see detailed comment on the design document on section "other
proposals that were considered".

Thanks,

Guillaume.

I'm excited to eventually bind services to more CF entities like
services. Binding a service to a route is as good away as any to start
users thinking that services could be bound to more than just an app.

I also have future requirements to apply functionality to a route that may
not necessarily be implemented in the form of a proxy. So, it would be
nice if this functionality were somewhat generic by not requiring a route
service to provide a proxy url and ensuring the GoRouter doesn't fail if it
comes across a route service bound to a route without a proxy url.

I'm not a fan of the proposed create-route/update-route cli syntax. Would
it be possible to bind more than one route service to a route with that
syntax? I'd prefer something like bind-route-service/unbind-route service
commands.

I cannot think of a situation where I'd like to have a route service
applied to one app but not another using the same route. The use case
doesn't really make sense given instance selection is random in that case
anyway.

As an added side bonus this approach would be simpler to implement in
NoRouter. :)

single argument could be interpreted as the DOMAIN and the space could be
an explicit option parameter.
I agree that space isn't needed, but I don't think we can remove it from
create-route until v7; that command already exists and space is a required
argument. Seems like it would be a backwards incompatible change for now.


cf create-service audit-service free-plan my-audit-service

this seems fine, it means create a service that is expected to have a
route-service endpoint the attributes, similar to a syslog drain service
right?
Correct, in response to create-service, the service broker will return a
route_service_url.


cf update-route foo example.com -s my-audit-service

we don't have "cf update-route" today. is the reason to make the
service_instance a parameter to account for more route options in the
future?
Yes, service instance would be an optional parameter because there are
others planned for the route commands and they should be independently
configurable. E.g. path is now supported in the API and will be added to
CLI soon.

cf update-route foo example.com -s my-audit-service -p /app/path


what about a "naked domain" that does not have a hostname like
example.com? this cli pattern above does not really allow for that
right? perhaps it's better to have a similar syntax to the existing route
commands:

cf update-route example.com -n foo -s my-audit-service
Agreed, we could support route services for naked domains.


what about supplying an external URL that is not a service on the
platform? would we do that with a user provided service instance or an
explicit URL added to the route?
# using a service
cf create-route development example.com -n foo -s my-audit-service

# using an external URL
cf create-route development example.com -n foo -u
https://audit.example.com
Instead of adding a second parameter for a similar purpose, I would
prefer use of a user-provided service to keep the relationships consistent,
the parameters generic (not specific to USPIs), and limit the number of
ways to accomplish a task to a predictable, familiar minimum.


how would we remove a route-service from a route, by using a particular
option that means remove any route-service on the route?

cf update-route example.com -n foo -r
Or using the same option with an empty string:

cf update-route example.com -s ''

I'll admit, the bind/unbind metaphor works better here. Instead of using
the create-map/update-map commands, we could consider
bind-route-service/unbind-route-service.

Again, we're still a ways out from the CLI work, and none of these tweaks
discussed here change the fundamental routing behavior we're proposing.
That is, that a route service url is associated with the route, and not the
app.

By binding different route services to applications that share a

that all requests for a route would be forwarded to the same route service,
and could not bypass it. The following CLI usage demonstrates the developer
workflow:

cf create-service SERVICE PLAN SERVICE_INSTANCE
cf update-route HOST DOMAIN [-s SERVICE_INSTANCE]
or
cf create-route SPACE DOMAIN [-n HOSTNAME] [-s SERVICE_INSTANCE]

This change would also mean that route services would not need to be

if you're using DEA's i believe the container stays around on the DEA for
about an hour or so by default before being removed.



assuming you're on a DEA, to investigate, you'd need to know the DEA and
the warden handle to investigate, log in to the DEA as an operator with

execute bin/wsh from the container handle directory.



see:

in diego, removing containers happens right away, but diego is also going
to support ssh for active troubleshooting and could just increase the
memory and attach jvm tools for debugging purposes to troubleshoot.



good luck.

I also have future requirements to apply functionality to a route that may
not necessarily be implemented in the form of a proxy. So, it would be
nice if this functionality were somewhat generic by not requiring a route
service to provide a proxy url and ensuring the GoRouter doesn't fail if it
comes across a route service bound to a route without a proxy url.

I'm not a fan of the proposed create-route/update-route cli syntax. Would
it be possible to bind more than one route service to a route with that
syntax? I'd prefer something like bind-route-service/unbind-route service
commands.

I cannot think of a situation where I'd like to have a route service
applied to one app but not another using the same route. The use case
doesn't really make sense given instance selection is random in that case
anyway.

As an added side bonus this approach would be simpler to implement in
NoRouter. :)

I agree that space isn't needed, but I don't think we can remove it from

cf create-service audit-service free-plan my-audit-service

this seems fine, it means create a service that is expected to have a
route-service endpoint the attributes, similar to a syslog drain service
right?
Correct, in response to create-service, the service broker will return a
route_service_url.


cf update-route foo example.com -s my-audit-service

we don't have "cf update-route" today. is the reason to make the
service_instance a parameter to account for more route options in the
future?
Yes, service instance would be an optional parameter because there are
others planned for the route commands and they should be independently
configurable. E.g. path is now supported in the API and will be added to
CLI soon.

cf update-route foo example.com -s my-audit-service -p /app/path


what about a "naked domain" that does not have a hostname like
example.com? this cli pattern above does not really allow for that
right? perhaps it's better to have a similar syntax to the existing route
commands:

cf update-route example.com -n foo -s my-audit-service
Agreed, we could support route services for naked domains.


what about supplying an external URL that is not a service on the
platform? would we do that with a user provided service instance or an
explicit URL added to the route?
# using a service
cf create-route development example.com -n foo -s my-audit-service

# using an external URL
cf create-route development example.com -n foo -u
https://audit.example.com
Instead of adding a second parameter for a similar purpose, I would prefer
use of a user-provided service to keep the relationships consistent, the
parameters generic (not specific to USPIs), and limit the number of ways to
accomplish a task to a predictable, familiar minimum.


how would we remove a route-service from a route, by using a particular
option that means remove any route-service on the route?

cf update-route example.com -n foo -r
Or using the same option with an empty string:

cf update-route example.com -s ''

I'll admit, the bind/unbind metaphor works better here. Instead of using
the create-map/update-map commands, we could consider
bind-route-service/unbind-route-service.

Again, we're still a ways out from the CLI work, and none of these tweaks
discussed here change the fundamental routing behavior we're proposing.
That is, that a route service url is associated with the route, and not the
app.

service X or to route service Y or directly to app C.

that all requests for a route would be forwarded to the same route service,

cf update-route HOST DOMAIN [-s SERVICE_INSTANCE]
or
cf create-route SPACE DOMAIN [-n HOSTNAME] [-s SERVICE_INSTANCE]

This change would also mean that route services would not need to be

to need credentials to contact the route service directly and CF doesn't
need to know the application in order to make the forwarding decision.

Thanks again to the CF Foundation for the great cf summit, and for
publishing so promptly the video recordings on youtube. The sessions
content is great to watch, and I'm sometimes lacking the high resolution

There is currently 12 slide decks onto [1] over the 38 sessions
presented. Is there somewhere else they can be accessed, or any way for the
foundation to publish the ones speakers have already posted on the CFP
system ?
I will double check with our content manager, but typically if slides
are missing it is because the speakers did not share the with us. If we do
still have some that have not been posted, I'll make sure that happens by
Monday.

Re: How to get files from crash apps

James Bayer
 

if you're using DEA's i believe the container stays around on the DEA for
about an hour or so by default before being removed.

assuming you're on a DEA, to investigate, you'd need to know the DEA and
the warden handle to investigate, log in to the DEA as an operator with
bosh, then go the warden depot directory, find the warden handle and
execute bin/wsh from the container handle directory.

see:
http://docs.cloudfoundry.org/running/troubleshooting/troubleshooting-apps.html#access-warden

in diego, removing containers happens right away, but diego is also going
to support ssh for active troubleshooting and could just increase the
memory and attach jvm tools for debugging purposes to troubleshoot.

good luck.

Re: Soliciting feedback on a UX change for route services

James Bayer
 

i personally don't like specifying the space in the "cf create-route"
command because it's one of the only cli commands i can think of that
requires specifying the space explicitly rather than using the currently
targeted space. i believe we should consider changing that now since a
single argument could be interpreted as the DOMAIN and the space could be
an explicit option parameter.

regarding the UX, i have tried some explicit examples with
comments/questions below:

cf create-service audit-service free-plan my-audit-service

this seems fine, it means create a service that is expected to have a
route-service endpoint the attributes, similar to a syslog drain service
right?

cf update-route foo example.com -s my-audit-service

we don't have "cf update-route" today. is the reason to make the
service_instance a parameter to account for more route options in the

By binding different route services to applications that share a route,
requests could be forwarded to these different services according to
GoRouter's load balancing algorithm. Imagine a route (foo.example.com)
mapped to three applications A, B, and C. App A is bound to route service
X, app B is bound to route service Y, while app C is not bound to a route
service at all. Requests to the route would be forwarded to either route
service X or to route service Y or directly to app C.

Instead of associating the route service with an application, we are
proposing associating the route service with the route. This would mean
that all requests for a route would be forwarded to the same route service,
and could not bypass it. The following CLI usage demonstrates the developer
workflow:

cf create-service SERVICE PLAN SERVICE_INSTANCE
cf update-route HOST DOMAIN [-s SERVICE_INSTANCE]
or
cf create-route SPACE DOMAIN [-n HOSTNAME] [-s SERVICE_INSTANCE]

This change would also mean that route services would not need to be
bindable, simplifying service development, as applications are not expected
to need credentials to contact the route service directly and CF doesn't
need to know the application in order to make the forwarding decision.

Let me know if you have concerns about this change in approach.

Re: Soliciting feedback on a UX change for route services

yes, this is how it should work.

How to get files from crash apps

MaggieMeng
 

We encountered java out of memory issue in our CF env recently. We had enabled gc log for the application by setting JAVA_TOOL_OPTIONS: -Xloggc:gc.log. But when out of memory issue occurred, the application was stopped and removed. We can't get gc.log. Is there any way to keep the gc.log after application crashes? The CF version we are using is 197. Any advice would be appreciated.

Regards,
Maggie
