Droplets and Stacks

Colin Humphreys <colin@...>
 

Hi All,

I wrote a couple of articles about droplets and stacks.

http://www.cloudcredo.com/a-droplet-of-value/

http://www.cloudcredo.com/stacks-of-problems/

The droplet post is fairly self-explanatory, and enabling the choice of
shipping droplets or source is well on the way in Cloud Foundry development.

I feel our story around stacks is far less complete. It seems to be an
overloaded concept inherited from Heroku and the contract with the stack
seems to cause issues for both app and buildpack developers.

I'd like to open the discussion on what the future should be for stacks, or
if you think they're perfect as they are.

Cheers,
Colin

Re: Removing FUSE support from CF

Onsi Fakhouri <ofakhouri@...>
 

Hey all,

Based on the feedback we got and the relatively low cost to maintain
privileged support we'd like to propose making running privileged
containers on the platform configurable - we will recommend this be turned
off when running untrusted workloads and it will likely default to off. We
have longer term plans to support mounting persistent volumes in Diego at
which point support for mounting FUSE in unprivileged containers can become
a reality.

Thoughts?

Well, that’s bad news.



We, and I assume many others as well (like the folks from Stackato who do
it in the public), have used SSHFS + FUSE to implement a persistent file
system for old-fashioned apps/apps that are not Cloud-native. I don’t want
to fight an ideological battle here, it’s just that these apps do still
exist (in majority) and a file system service is an important
service/feature for them.



So if you remove FUSE (which we thought is not going away/was added to
stay), it’s pretty bad for us/many apps.



Best regards, Vedran
+1 - It would be sad to see FUSE support go away. It's been very helpful
for running apps that depend on a persistent FS, like Wordpress. Perhaps
this use case of mounting a remote SSHFS could be supported in some other
way?

Hey CF-Dev,



The Garden team has been hard at work substantially improving
Garden-Linux's security features. Garden-Linux now employs user namespaces
and drops capabilities when creating unprivileged containers - we're
excited to bring both of these features to the platform!



Diego currently runs applications in *privileged* containers. These
lack the security features outlined above and we are planning on switching
to launch all CF applications in *unprivileged* containers.



Unfortunately, it has proved difficult to support
mounting FUSE filesystems from within unprivileged containers. We believe
the security benefits outweigh the features that FUSE give us and* are
planning on removing support for FUSE in favor of better securing our
containers.* If/when FUSE support in unprivileged containers becomes
possible we may add it back to the platform.



Thoughts? Concerns?



Thanks!

Re: Logstash and Multiline Log Entry

Steve Wall <steve.wall@...>
 

Now I see what that means. Each line of a multiline log message could be
sent to a different logstash server. Definitely problematic. Especially
with the ephemeral nature of the CF logs there needs to be a viable
solution to persist the logs and syslog seems to be a natural solution. I'm
located in Denver and attend the local CF meetups held in the Pivotal
offices. I believe some LAMB devs attend. I'll be sure to bring it up with
them.

you don't get to set the expiration time, since that doesn't make sense

Re: Notifications on ORG, SPACE and USER modifications

Mike Youngstrom <youngm@...>
 

For us the main use case is security auditing to keep a long term record of
who has done anything. In the case of our Security team rather than use CF
events directly they preferred to have events forwarded to Security
Analytics. Today we pull events then forward the details to Security
Analytics via a syslog endpoint.

I’m going to need something like this too for the CF Abacus service
metering project, as I’d like to track the lifecycle of orgs, users, etc to
match their history with the usage data reported for them.


Here’s a straw man description of what I had in mind:


- For Abacus, I’d need a Lossless API. Usage metering eventually
translates to billing and money, you don’t want to lose that :)


- An extension or variant of the current CF /v2/events API supporting
users, orgs, app usage etc, as even with a notification API I’ll still need
to do GETs sometimes.


- 304 responses with etags on these GETs (as suggested earlier in the
thread [1]) would be good.


- A Webhook style notification API where I could register interest in a
selection of events with a callback URL, and get these events POSTed back
to me at that URL, similar to what Github and many others do with Webhooks.


- On top of Webhooks, it’d be nice to have a form of streaming (either
down to the client like the Firehose does or in the other direction up to
the Webhook callback URL), but I'm not sure if we’ll need that in the
project right away.


- We’d obviously need some form of security, maybe use my user token to
register for events on entities that I have access to?


- I’m also curious about the group’s thoughts on queueing and
back-pressure when events get generated faster that they can be consumed
for example. There was a mention of some message queuing earlier [2]. That
would make sense to me (although IMO it’d be good if the underlying MQ
didn’t shine through the API). What did you have in mind for this?


I guess there are quite a few things to figure out here! I’ll be happy to
collaborate with the community on these discussions.


Thoughts?

I've wanted something similar as well.



On a related note, having a CC API 'serial' number (for each object in
CC - apps, spaces, etc) that increments on every change relevant to that
object would be of value for detecting if something has changed.

The requests I've seen have been around wanting to be able to

that other behavior could be triggered.

We currently have events, app usage events, and service usage events.

Is it acceptable for the notifications to be lossy? Depends on the
use case but If so, then the firehose may be an acceptable approach.



The CAPI team is currently focusing on other work in the near term,

What do you think?
Any other idea you might have?

If I set the access_token_validity to 315569260, I'm expecting the token
when decoded to read exp: 315569260. If this is not, then is it possible to
set the token expiry time?

It's a little bit different.

access_token_validity is how long the token is valid for from the time of
creation. thus we can derive

exp (expiration time) = token creation time + access token validity

you don't get to set the expiration time, since that doesn't make sense as
the clock keeps ticking forward.

in your case, having access token validity be 10 years, achieves exactly
what you want

line 906 sets the value to 1438209609 when the token is decoded and I
believe that's what the check_token service also checks.
expirationTime*1000l occurs after the token has been decoded (whose exp
value is set to 1438209609)

Now the question is why do you have to do expirationTime*1000l since the
token when decoded originally set's this value to 1438209609 (without *
1000l)

Except I'm completely getting this all wrong?

There have been several proposed solutions but I'm not aware of anything
actually making it into the LAMB tracker. It would be great if we could
hear from Erik on this issue. Does the LAMB team believe it is not an
issue? Are there plans to improve this situation? Whatever the
perspective lets discuss it as a community and see if there are any options
better than the current. I'd really like to see something turned into a

This is a tricky one. Especially if you have more than one logstash

The reason why CF adds a timestamp to each line is because how syslog
works, where each line is its own even.

What we tend to do in my company is to log this kind of stuff via GELF or
with Sentry.

Hello,
We are sending CF logs message to an ELK stack. Multiline logs message
are broken out into several log messages in Logstash. One end per line of
the multiline log message. This is problematic when stack traces dumped to
the log. Each line of the stack trace is translated into a log message.
Trying to view this through Kibana is nearly impossible. Logstash provides
a Grok feature allowing for the manipulation of the log messages. One
common solution is to create a Grok filter that using a timestamp to
indicate when a log entry starts and to combine all lines until the next
timestamp into one log message. The problem is that CF adds a timestamp to
every line. Has anyone come up with a good Grok expression to handle
multiline log message coming out of CF?
Thanks!

Re: Node.js Apps with small memory limits; Inaccurate Memory Availability in Containers

Mike Dalessio
 

Hi Sai,

Thanks for asking these questions. The buildpacks team, who currently
maintains the nodejs-buildpack, is totally open to improving the node.js
developer experience.

I'd love to hear about anyone's experience managing the total heap size
within the node.js interpreter. If you have played with this, let us know,
and we'd be happy to work with you on how it might work in conjunction with
container memory limits.

Cheers,
-mike

Hey All,

I've recently started investigating a memory issue with Node.js apps
running in CloudFoundry environments. FYI, I'm using CFv210. As an
example, if I push a Node.js app with a mem leak with a 512MB memory limit,
the Node.js V8 engine tries to allocate more and more memory until it
passes that memory limit and the application crashes. The behavior I expect
to see is that it will stop trying to allocate more memory when it reaches
the limit, and instead try to GC more aggressively (and then crash at a
later time).

By default, on 64 bit machines, the Node.js v8 engine has a 1GB heap
limit, so I can see why the engine tries to allocate more than is really
available. There should be some way to prevent the Node.js v8 engine from
trying to allocate more than is available. In Java, you can use JVM opts to
set heap limits, maybe something similar?

I did find one thing that might help, --max-old-space-size. But... has any
one done any investigation as to how to set that space size?
"--max-old-space-size" only accounts for the v8 engine's heap, not the
buffers or other processes. For example, should that limit be set to 50% of
the memory_limit? 75%? Maybe that's something the Node.js buildpack should
set as a reasonable default?

There is a separate issue that might be related to this. When you run
'free' or 'top' as a shell command from within the container spun up for my
application, I am seeing "32gb" total. This can't be right... I specified
512 when creating my application! When I run commands like "os.totalmem()"
from within Node.js, I'm also seeing 32gb.

There may be a better solution that doesn't involve setting any params,
but instead just fixing those kernel commands to be accurate.

Thanks,
Sai

Re: Invalid password change request

Filip Hanik
 

I don't think the schemas belong there, that may be a copy paste error in
the docs.

The easiest reference for the REST API may be the integration tests

https://github.com/cloudfoundry/uaa/blob/develop/uaa/src/test/java/org/cloudfoundry/identity/uaa/integration/PasswordChangeEndpointIntegrationTests.java#L141-L161


Here are the steps that you can take to reproduce it

Terminal one - Startup the UAA
./gradlew run

Terminal two - Change the password

1. uaac target http://localhost:8080/uaa
2. uaac token owner get cf marissa -s "" -p koala
3. uaac token decode (copy the user_id)
4. uaac -t curl -H"Accept:application/json"
-H"Content-Type:application/json" -XPUT -d '{"password":"newpass",
"oldPassword":"koala"}' /Users/a985b50b-0263-4db8-bbf4-1ac832acc4c3/password

that;s it. the uaac curl adds the -H"Authorization: bearer ..." header. But
you can do it all with curl

Re: UAA: How to set client_credentials token grant type to not expire

Filip Hanik
 

Token validity is how long a token is valid for from the time it is
created. The token will store the expiration time, that is the date when
the token expires.
so `"exp":1438209609` is actually the date in seconds when it expires.

To translate exp into a date, you would do

Date expirationDate = new Date(1438209609 * 1000l);

Here is a test case that demonstrates it

https://github.com/cloudfoundry/uaa/commit/f0c8ba99cf37855fec54b74c07ce19613c51d7e9#diff-f7a9f1a69eec2ce4278914f342d8a160R883
