   ### Problem
   - (airflow) The `airflow-xcom-sidecar` container waits a SIGINT signal by `trap "exit 0" INT;`. 
   - (airflow) The pod launcher in the airflow package stops the sidecar's main processor by `kill -s SIGINT 1`
   - (k8s) The PID1 process can be a init process made by a container runtime like the docker.
      - In the top example. The sidecar's main process is not PID 1. 
   - In the top example, the command (`kill -s SIGINT 1`) makes the 137 exit code.
   
   ### Expectation
   - The pod launcher can send the SIGINT signal to the sidecar's main process other than PID 1 only.
