Prevent Kubernetes from killing 2 nodes at the same time -------------------------------------------------------- Key: ISPN-7494 URL: https://issues.jboss.org/browse/ISPN-7494 Project: Infinispan Issue Type: Sub-task Components: Cloud Integrations, Core Affects Versions: 9.0.0.CR1 Environment: * OpenShift {{v1.5.0-alpha.2+e4b43ee}} * Infinispan Server 9.0.0.Beta2 Reporter: Sebastian Łaskawiec Assignee: Sebastian Łaskawiec Priority: Blocker When I was performing [Spring Session and Kubernetes Rolling Update demo|https://bluejeans.com/s/pYKUg/] I encountered a couple of problems. One of the is this: {noformat} [transactions-repository-1-hqz3v] *** JBossAS process (83) received TERM signal *** [transactions-repository-1-dwl81] 09:52:09,522 INFO [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal [transactions-repository-1-dwl81] *** JBossAS process (80) received TERM signal *** [transactions-repository-1-hqz3v] 09:52:09,526 INFO [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal {noformat} Full logs from Rolling Update process might be found here: https://gist.github.com/slaskawi/2308b4c5e9bbf523fb3e02a7cc45fa24 Steps to reproduce: * Start local OpenShift Cluster * invoke `./init_infrastructure.sh` from https://github.com/slaskawi/presentations/tree/ISPN-7487-reproducer * invoke `cd transaction-creator && mvn fabric8:run` * Start Spring Session Demo `cd session-demo && mvn fabric8:run` * Create a client which inserts data (`watch -n 0.5 curl http://<spring-session-demo-pod-ip>/sessions`) and at the same time invoke the rolling update: `oc deploy transactions-repository --latest -n myproject` * Observe logs `kubetail -l environment=infrastructure`
