livelaceapuimedo, Ping17:10
apuimedolivelace: pong17:17
livelaceapuimedo, Sorry for interruption, but I see that CNI daemon have an error with initial starting17:20
apuimedolivelace: do you have a stacktrace?17:21
livelaceapuimedo, https://paste.fedoraproject.org/paste/psSZzzWysGDG5BKdTqGBZg17:21
livelaceAs you can see we got CONTAINERID using --cacert /var/run/secrets/kubernetes.io/serviceaccount/ca.crt17:22
livelaceBut after that we got an SSL error, during access k8s API17:23
livelaceBut if I run another one kuryr-daemon inside that container with different ports I get:17:23
livelacehttps://paste.fedoraproject.org/paste/mVChr~AE3aTsZzLsBGXwlQ17:24
livelaceThere is no SSL problem anymore17:24
livelaceAnd I don't understand why17:24
livelace*yet17:24
apuimedothis is really strange17:25
livelaceDuring deployment of CNI daemons I set ssl_verify_server_crt = False17:26
livelaceBut it doesn't help17:26
apuimedolivelace: maybe it is only used in the actual client17:27
apuimedonot in the health check17:27
* apuimedo checking17:27
livelaceThere are k8s = clients.get_kubernetes_client() everywhere17:28
livelaceAnd k8s_client has         response = requests.get(url, cert=self.cert,17:28
livelace                                verify=self.verify_server,17:28
livelace                                headers=header)17:28
apuimedothat's right17:29
*** maysamacedos has joined #openstack-kuryr17:30
livelaceAnd the second CNI daemon inside the same container/daemonset looks fine17:30
livelaceWhen I started it, webconsole container got IP-address17:31
apuimedocould you check the /proc/num_proc/cmdline of the working and the non-working?17:31
livelaceoriginal: /usr/bin/kuryr-daemon --config-file /etc/kuryr/kuryr.conf17:34
livelacesecond: /usr/bin/kuryr-daemon --config-file /tmp/1.conf17:34
apuimedolivelace: can you paste me a diff of the config files?17:34
livelacethe second has config where I just changed port numbers17:34
livelaceapuimedo, https://paste.fedoraproject.org/paste/xgOyGeQnF~mIO1JPCrCifw17:35
apuimedolivelace: did you try which of the three changes makes a difference?17:38
livelaceapuimedo, Do think that ports make sense ?17:38
apuimedoI would try with only the 8091 change to see if it is just that17:39
*** salv-orlando has quit IRC17:39
*** salv-orlando has joined #openstack-kuryr17:40
*** salv-orlando has quit IRC17:44
apuimedolivelace: since the cni daemon runs on the host namespace, did you check if something else runs on 8090?18:09
apuimedoor is it just a race?18:09
*** gcheresh_ has joined #openstack-kuryr18:09
livelaceapuimedo, Of course I check, I wouldn't have any running cni daemons/contollers, if they all listen the same port18:10
apuimedoso, did you do the previous check I asked you of starting the second daemon only changing the health server port?18:11
livelaceapuimedo, Yes, I set port number 8091 in config and in deployment config18:13
apuimedoand just with this change it worked?18:14
apuimedowithout touching the bind_address settings?18:14
livelaceNo. There is the same problem18:15
apuimedook, so then the problem will be with the bind_address, most likely18:15
livelaceNow, I'm trying to remove any readiness/liveness checks from daemonset18:15
apuimedofor downstream we don't use the cni health checks18:16
apuimedocause it didn't make it into stable/queens iirc18:16
livelaceHm18:17
livelacehttps://paste.fedoraproject.org/paste/O6Di7KevEqsOg2kJPwzuUw18:18
livelaceI have removed readiness/liveness checks from daemonset18:19
livelaceI didn't change any port number, I stay it 809118:19
apuimedolivelace: which image is this?18:19
livelacelatest18:19
apuimedokuryr/cni:latest18:19
apuimedook18:19
apuimedowell, I mean, it makes sense that if the error is in the CNI health check it would not happen if the kubelet does not probe it18:20
livelaceapuimedo, I'm going to deploy cluster from the beginning with disabled readiness/liveness18:22
apuimedolivelace: enable_kuryr_cni_probes is the setting to set to false18:22
apuimedolivelace: how long does the deployment take for you?18:23
livelaceapuimedo, I know, I explored those things enough :)18:23
livelaceapuimedo, About 30 minutes18:24
livelaceapuimedo, I can write about results tomorrow, I decided to have working installation :)18:25
apuimedolivelace: perfect18:25
apuimedolet me know how it goes18:25
apuimedoI'll leave IRC on18:25
livelaceapuimedo, Ok, thank you for your answers18:25
apuimedoif you get results earlier, maybe I can look at the problem tonight18:25
apuimedono, thank you for the issue report. It is much appreciated!18:25
livelaceOk18:25

livelaceapuimedo, First glance - it's working. deployment was born container, container has IP-address, service was created in Openstack, that service responds :)19:16
livelaceDeletion working fine, Lbass was deleted, port is free.19:17
livelaceI think, smoke test passed :)19:17
livelaceBut, more things I can say when I deploy production cluster and launch many containers and virtual machines on it.19:18
livelaceapuimedo, Thanks again!19:18
