Kubernetes on EC2 with Single Cartridge App
Hi Devs,
I was able to set up kubernetes on ec2 with master node and one minion
node. Then I pulled the stratos/php:4.1.0 docker image to the minion node
and deployed the single cartridge app. But I got the same error mentioned
in a previous thread "Problem in Kubernetes with Stratos master branch"
although I have pulled docker image to minions.
Then I ran live test as mentioned in the above thread and it was
successful. I redeployed the application again. Then the application got
activated and I was able to access the php app. But activated pods do not
last more than one minute. Faulty member detected message comes and creates
a new pod. I think this is happening as the cartridge does not publish
events to CEP and it causes to identify this pod as inactive.
I am using stratos/php:4.1.0 docker image.
How can I overcome this problem?
Do we need to run live test every time when we create a kubernetes cluster?
Thank you!

Hi Imesh,
I rechecked the kubernetes cluster json and changed my CEP_PORT to 7711
which is the thrift SSL port. I have used the thrift port which is 7611 in
my json. That could be the reason why cartridge agent was unable to send
stats to cep. Now kubernetes cluster is working fine.
Thank you!

Hi Pubudu,
Did you update the Kubernetes Cluster JSON with the IP addresses of your
EC2 instances? May be it was updated properly:

Hi Pubudu,
Shall we have a look on cartridge agent logs?
Thanks.
