nsmgr pod in crashloopback state

vishnuitta commented 4 years ago

This is related to issue at: https://github.com/networkservicemesh/networkservicemesh/issues/1972 Tried interdomain feature as per demo at NSMCon, nsmgr is in crashloopback state nsm-system nsmgr-chcct 2/3 CrashLoopBackOff 208 18h

Steps performed:

Created single node cluster using GKE and EKS consoles
Obtained kubeconfig of above clusters
Followed step1 and 2 of https://github.com/tiswanso/examples/tree/demo_vl3/examples/vl3_basic (so checked out tiswanso/networkservicemesh and tiswanso/examples of branches specified in README.md)
And then the steps at Mysql Demo example in same page

At this point, mysql installations failed probably due to variables in helm.. but, a container in nsmgr also in crashloopback state and its logs are as shown above.

Another observation: If I restart the nsmgr pod by deleting it (so that it comes up again), all three containers comes to running state, but, it gets into 'CrashLoopback' state after some time.

any other steps I need to do to try out interdomain feature @tiswanso

tiswanso commented 4 years ago

Did you create the firewall rules for each public cloud cluster's VPC as described in this section: https://github.com/tiswanso/examples/tree/demo_vl3/examples/vl3_basic#public-cloud-setup ?

Regarding the nsmgr crashloop after a while ... I've also seen that but haven't done troubleshooting to get to the bottom of it. Been focusing on moving the virtual L3 to the latest master.

vishnuitta commented 4 years ago

that makes sense to get the feature moving @tiswanso .. Regarding steps given at public-cloud-setup, I hadn't followed them. I will do that. This may be the reason why slave is NOT able to connect to master even after restarting nsmgr pod

vishnuitta commented 4 years ago

getting this error while doing aws-start:

I will fix this and let you know.

BTW, few qns:

any help on above error would be great
why only proxynsmgr firewall rule is NOT created through script, but, manually by user?

Can you please provide next steps to try for pod-to-pod connectivity across clouds?

I will also document the issues that I faced during the make of setup and the reasons for same.

And one more: I don't have any environment variables set for NSM_AWS_SERVICE_SUFFIX during the make of setup. So, its empty.

Not able to understand how empty networkservice got created

vishnuitta commented 4 years ago

ok.. got to see that pe function itself doing the deployment of networkservice as well

@tiswanso Tried couple of times again. Almost same state, except that, mysql-slave comes to Running state, but, slave status shows as Connecting

mysql> show slave status \G
*************************** 1. row ***************************
               Slave_IO_State: Connecting to master
                  Master_Host: 172.31.239.1
                Last_IO_Error: error connecting to master 'demo@172.31.239.1:3306' - retry-time: 60  retries: 144

Observations:

Made sure that nodes of both clusters are reachable to each other on those required ports 30500-30599
vl3-service networkservice CR gets deployed as Empty. Re-applying the CR and restarting all NSM pods also didn't helped.

This time, changes done to helm's values.yaml are as follows, so that, demo_vl3.sh works as it is:

- Restarting NSM and mysql-slave related pods made mysql-slave to `Init:0/1` state
