jgrasslerGood evening.15:11
*** muralia_ has joined #openstack-containers15:12
jgrasslerI'm currently looking into running Magnum API with SSL enabled...there appears to be no configuration, and I'm finding none of that in the code either.15:12
jgrasslerDoes the Magnum API have no SSL support at all or am I missing something?15:12
*** swatson has joined #openstack-containers15:13
jgrasslers/no configuration/no configuration for certificates and keys/15:13
*** elo has joined #openstack-containers15:13
*** muralia has quit IRC15:15
Dragojgrassler: Magnum can be configured to use TLS15:15
jgrasslerDrago: Where are the settings (certificate, CA certificate, etc.) for this?15:19
jgrasslerDrago: (I can't find them anywhere in the sample configuration file generated using `tox -egenconfig`)15:19
*** rcernin has quit IRC15:22
Dragojgrassler: See http://docs.openstack.org/developer/magnum/userguide.html#transport-layer-security15:23
DragoI'm no expert in how TLS was implemented in magnum, but I'll hunt around for things15:24
Dragojgrassler: TLS can be disabled per-baymodel (it's on by default) https://github.com/openstack/magnum/blob/master/magnum/db/sqlalchemy/models.py#L17515:24
jgrasslerDrago: Yes...that's the Bay-to-API side. I found settings for that. But how do I enable TLS for the communication between python-magnumclient and the Magnum API?15:26
Dragojgrassler: That I don't know15:28
*** sdake_ has joined #openstack-containers15:29
jgrasslerDrago: Ordinarily I'd just run magnum-api in Apache and be done with it, but since the API needs dynamic certificates for the per-bay encryption that's not really an option...15:29
Guest52040hongbin: https://blueprints.launchpad.net/magnum/+spec/magnum-doc-rest-api15:29
Guest52040hongbin: i saw that we currently had a Bp related to api ref15:29

Guest52040ack15:30
Guest52040where is my nick..15:30
hongbinYou have questions regarding to that BP?15:30
jgrasslerDrago: Anyway, thanks for looking. I'll keep on trying to figure out how to make it happen :-)15:30
Dragohongbin: I've been most unhelpful to jgrassler. Any ideas?15:31
hongbinDrago: catching up the logs15:31
*** hieulq_ has joined #openstack-containers15:31
hieulq_Ok got the nick back :(15:32

hieulq_hongbin: yep, thanks15:33
hongbinhieulq_: You Laundpad ID is?15:34
hieulq_hongbin: my id is hieulq15:34
hieulq_hongbin: got it, thanks15:36
* hieulq_ hope that he can get a ticket to Barcelona and join Magnum design sessions15:40
hongbinjgrassler: Hi15:42
hongbinjgrassler: About the API SSL, these are the configure I can find "enabled_ssl_apis", "ssl_cert_file", "ssl_key_file". (under default)15:42
hongbinjgrassler: If it doesn't work, would appreciate a bug to report that15:43
hongbinDrago: It looks we missed a document for how to enable ssl at magnum-api15:45
Dragohongbin: Good find15:45
*** jvgrant has joined #openstack-containers15:45
hongbinMight need to create a ticket for that. Let me do it15:46
*** yatin has joined #openstack-containers15:46
jgrasslerhongbin: ssl_cert_file and ssl_key_file are under [oslo_messaging_rabbit] in the configuration from `tox -egenconfig` - and they occur nowhere in the Magnum code base (neither master nor stable/mitaka).15:48
hieulq_hongbin: I think enabled_ssl_apis doest not work with Magnum API15:49
hongbinYes, then it is a bug15:49
hieulq_hongbin: our current code did not handle anything related to this option15:49
*** zenoway has quit IRC15:50
hieulq_jgrassler: the Oslo config generator at master branch and Mitaka branch are not configured in the right way15:50
*** zenoway has joined #openstack-containers15:50
hieulq_jgrassler: so tox -e genconfig will generate the sample file that contain not enough config options15:51
hieulq_jgrassler: but the fact that enabled_ssl_apis existed in DEFAULT section15:51
hieulq_jgrassler: I think you can try it, but as said above, maybe current Magnum codebase does not support SSL API15:52
*** zenoway has quit IRC15:55
jgrasslerhieulq_: Probably not, no :-/15:55
jgrasslerhieulq_: These settings do not show up anywhere in the Magnum code base proper: https://gist.github.com/jgrassler/343041191911f5746599547a2d321f4815:55
jgrasslerThey only reference to `enabled_ssl_apis` is a devstack script setting this option in magnum.conf and the other two are SSL options for the RabbitMQ client.15:56
hongbinhttps://bugs.launchpad.net/magnum/+bug/161459615:57
openstackLaunchpad bug 1614596 in Magnum "Add support for SSL for magnum-api" [High,Triaged]15:57
hongbinCreate a ticket for that15:57
jgrasslerhongbin: Thank you! :-)15:57
hieulq_jgrassler: agreed and thank hongbin for this ticket15:57
*** chandankumar has joined #openstack-containers15:59
jgrasslerHmm...I have an idea for a stopgap measure. Not sure if it's feasible, though. Which API endpoint does Magnum pass into the Heat stacks it creates?16:00
jgrasslerIf it's internalURL, my stopgap measure might just be feasible...16:01
jgrasslerBecause in that case I could run the publicURL instance of Magnum as an WSGI app in Apache (with Apache taking care of SSL).16:02
*** jberkus has joined #openstack-containers16:04
*** vijaykc4 has quit IRC16:05
*** yamamoto has joined #openstack-containers16:06
jgrasslerOk, it's configurable. So for a cluster that allows access to internal URLs from instances this might just be feasible. Ugly though :-)16:06

jvgrantany cores on that could review this: https://review.openstack.org/#/c/353726/ i'd like to get it in or get more updates on it since there are now other patches blocked by it20:29

tushar_kHi, I have a question about accessing the containers. I'm trying to run commands inside the pods using kubectl but it throws an error that k8s cannot lookup the minion by the hostname, how do I resolve this?20:58

jvgranttushar_k: you were able to get through all the commands in section? or did it fail at redis setup where you first make kubectl calls?21:41

*** dane_leblanc has joined #openstack-containers22:00
tushar_kjvgrant: the redis pod was running, only when I made the kubectl calls to it that it failed22:17
tushar_kjvgrant: also in my environment I cannot ping the minion by hostname from the master node22:18
*** julim has joined #openstack-containers22:19
jvgranttushar_k: when you do a nova list do you see the same hostname for the minion?22:20
jvgrantalso docker ps?22:21
tushar_kjvgrant: yes I do see the hostname when running nova list22:33
tushar_kjvgrant: and docker ps does show up all the running containers22:33
jvgranttushar_k: i'm trying it out to see if i can reproduce it22:39
jvgranttushar_k: is there a difference when running docker exec vs kubectl exec?22:42

tushar_kjvgrant: kubectl has to first find out the minion before it can run exec so that's where the problem is occurring  now22:48
*** daneyon has quit IRC22:50
jvgranttushar_k: there is a Kubernetes networking section under in https://github.com/openstack/magnum/blob/master/doc/source/troubleshooting-guide.rst that might have a few things you can try22:50

tonanhngoHi tushar_k, there is a know limitation with "kubectl exec"23:14
tonanhngoIt doesn't work currently because we don't have DNS deployed to provide the host name look up for the minion23:14
tushar_ktonanhngo: Thank you for this information!23:18
tushar_kjvgrant: Thank you for your help too!23:18
tonanhngoHere is the bug:  https://bugs.launchpad.net/magnum/+bug/151167923:18
openstackLaunchpad bug 1511679 in Magnum "kubectl exec fail with 500 (dial tcp: lookup no such host)" [Undecided,New] - Assigned to Ton Ngo (ton-i)23:18
tonanhngoSorry I haven't gotten around to it yet23:19
tushar_ktonanhngo: I'll follow this bug thanks! Is there a workaround to using kubectl exec?23:27
tonanhngoyou can just log into the particular minion node and run docker exec23:28
tonanhngoThat's mostly what kubectl exec does for you23:28
