guillotine

Purpose

In Kubernetes Job, containers should be terminated to become successful. There are no straight way to terminate sidecar containers because Process can't send signal in another container(PID namespace is not supported).

guillotine manages the lifetime of child process to solve this problem.

Usage

GUILLOTINE_WATCHED_FILE=/tmp/job-success guillotine /cloud_sql_proxy -fuse

guillotine launch child process by args and poll the file exists periodically. When /tmp/job-success exists, cloud_sql_proxy is killed.
