Rolling upgrade support for in-flight requests
Three entry points are being handled : 1 - REST endpoint 2 - gRPC endpoint 3 - Kafka consumer We make use of Phaser object to make sure the PreDestroy callback wait for all requests to be executed before stopping the process. The docker image was also modified to make sure the java process becomes PID 1 in the container in order to catch the SIGTERM signal which triggers the PreDestroy callback of Spring. This was done by using the "exec" command in bash. Issue-ID: CCSDK-1885 Signed-off-by: Sebastien Premont-Tendland <sebastien.premont@bell.ca> Change-Id: I64611e569ddb78499aed2375e6186f028d1d8fa0
