Re: On SelfServiceLinksEnabled #uaa

Dan Beneke
 

Hi CG - 

It looks as if you've taken the right step to disable the create account and password reset links.  We'd expect selfServiceLinksEnabled to have the documented effect (determines if users are allowed to sign up or reset their passwords via the UI) and aren't aware of open issues with its function.  Keep in mind that this value isn't global as it can be set for each individual identity zone.  If you think you've found a bug/issue, I'd encourage you to open a github issue supplying content that will allow the team to recreate the situation.

As for suppressing just one of the two self service links, that feature isn't offered.  Currently, enablement or disablement occurs jointly.  If it's of any value, you do have the option to set the destination http link for the 'create an acct' experience using config.links.selfService.signup .  I've seen implementations wherein this link takes users to a joint self service page with the information they need to either create an account or reset their password.

Regards,
Dan Beneke

Re: New CLA tool for Cloud Foundry

Chris Clark
 

Hi all,

I’ve got a few updates to the EasyCLA migration, now a few months behind us:

 We’ve removed the prompt to click on “CFF Migration” for previously whitelisted contributors. We’ll be deprecating this shortly, as it was intended as a temporary bridge to minimize disruption to contributors and avoid having covered committers and companies re-sign a CLA. At this point we assume the vast majority of active committers has already signed up with EasyCLA (anyone who has a commit since October has, and that's over 500 committers). Going forward, we’ll ask everyone else to sign a new CLA, which should only take a minute or two. 

Previously, the cloudfoundry and cloudfoundry-incubator GitHub orgs had been whitelisted. This should not have been the case. While the majority of these orgs’ members are covered by an existing CCLA or ICLA, membership in those orgs alone should not exempt committers from being covered by a CLA. Going forward, these orgs will not be whitelisted… so, if you’ve authorized EasyCLA with "CFF Migration" and your whitelisting was based on membership in one of these orgs alone, you may need to re-authorize EasyCLA and select your employer's CCLA, or sign an ICLA. Either way, this should just take a couple minutes.

Bots: If you have an issue with a CI (or any other) bot that makes commits (and therefore will trigger the CLA check), please open a ticket with LF IT (the EasyCLA app will prompt this in the GitHubPR), and they should be able to take care of this for you.

Please reach out to me, or LF IT, if you have any questions, issues, or feedback. Thank you again for your patience with all this!  

 

 


Re: enable 2fa for UAA zone

Peter Burkholder
 

Sorry my response was so blunt. Product tradeoff decisions are always hard and you can't make everyone happy. Just wanted to let you know that there are consumers for this feature if you do revisit anytime soon.


Re: enable 2fa for UAA zone

Peter Burkholder
 

We see the UAA more frequently used as an identity proxy than as an IdP

This may be true because UAA doesn't support MFA. 
cloud.gov runs its own IdP simply because MFA is not supported by UAA. To quote from Bret Mogilefsky from 
https://github.com/cloudfoundry/cf-deployment/pull/540

This is a shocking disappointment. The cloud.gov team predicated a chunk of their roadmap on the understanding that MFA was staying.


Re: enable 2fa for UAA zone

Dan Beneke
 

Hi CG - 

The 2FA/MFA feature still exist in the most recent versions of UAA, but Dr. Nic is correct in suggesting that our intent is to remove it.  We see the UAA more frequently used as an identity proxy than as an IdP, and often the IdP feature is used to store service accounts over actual human users that would be able to interact with 2FA/MFA flows.  The predominance of this usage pattern has led us to consider viewing UAA on a path to become a stronger identity proxy tool wherein the user brings their own identity (IdP).  This suggests 2FA/MFA features would/could be applied to the external IdP and not to the UAA itself as it would only be acting as a proxy.

Regards,
Dan Beneke

enable 2fa for UAA zone

JohnG
 

Greetings.

I hope this mailing forum can give me pointers on the following

How to enable 2fa (but-in google-authenticator) for UAA (base and default
zone)?

After creating a 2fa provider, when I try to update UAA zone via curl/api
post with update setting mfaconfig etc. I don't see any response back (yes,
with right admin client access token)

Also when directly updated the database query on identity_zone, config, when
it reboots it restores mfaconfig enabled to false.

Is there something 'am missing ; appreciate any pointers on this

Thanks
CG

Re: CF app that helps with self-healing

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

To me this seems a lot like a health check.  Is there some reason that you couldn't add a health check endpoint to your app instances (either directly, or as a sidecar) and then let CF take care of restarting the app instances for you?

I am aware of all the options you are suggesting. But what we are looking for is a process to restart an app instance without human intervention from an alert policy in our monitoring system. This monitoring system is outside of CF and does not have access to CF CLI. But it can access REST endpoints.

The cf cli is just a glorified rest client. If you can access the cloud controller API for your foundation, you can do everything I mentioned w/out the cf cli & by using raw rest commands.


+1 to everything Daniel Jones said in his response.

Hope that helps!

Dan

 
For eg - The monitoring system will detect a high CPU utilization on one of the app instance. It will raise an alert which will trigger a policy that will call a REST endpoint of this self healing app. Based on the parameters passed in the request, the self-healing app will restart the requested app instance.
This is required when the app does not know that it is in a bad state but some metrics we are tracking are indicating that the app instance need to be restarted.
Hope that makes sense.

Re: CF app that helps with self-healing

Daniel Jones
 

Hi Siva,

I'm not aware of a similar solution that already exists. A couple of thoughts:
  • Could you use HTTP healthchecks, and have the endpoint return a non-200 status code if the app detects high CPU usage itself?
  • Be mindful of how CPU usage is reported. Whilst current containerisation tech can limit how many CPU shares a process gets, it can't control the system calls that report how much CPU is available. Hence things like `top` will appear inaccurate, and you should ensure the CPU usage statistics come from the metrics that feed into the cpu-entitlement-plugin. If you want to double-check this, there's a blog post (https://www.cloudfoundry.org/blog/better-way-split-cake-cpu-entitlements/) and the folks in the #garden channel are awfully helpful.
  • Having an endpoint that allows remote termination of an app sounds like a bit of a security risk, but I'm sure you'll manage that appropriately.
