tini spawning shell not CMD

[vitosans]

Not sure if this is an issue or user error.

• tini (version 0.9.0)
• Docker 17.06.1-ce-rc1-mac20 (18682)
• Alpine 3.6

I have two containers that I am experimenting using tini and su-exec with. The first container is a tomcat container and everything is working just fine, a text book example if you would.

The second container is a Redis container and this one for some reason only wants to run /bin/sh not what ever is in the CMD of the Dockerfile.

ENTRYPOINT ["/sbin/tini", "--"]
CMD ["start-app.sh", "redis-server", "/etc/redis.conf"]  

The contents of start-app.sh are not much

if [ "$1" = 'redis-server' -a "$(id -u)" = '0' ]; then
    # Change the ownership
    chown -R redis:redis /data
    exec su-exec redis:redis "$@"                                                                                                                                                       
else
    exec "$@"
fi

When I build and run this my container exits immediately.

docker logs -f redis is empty

docker inspect -f "{{.Name}} {{.Config.Cmd}}" $(docker ps -a -q)

/redis [/bin/sh]
/tomcat [start-app.sh catalina]

So I see that Tomcat is working but for some odd reason the Redis container is only running a shell.. The weird thing is both containers inherit from the same base Alpine container except the Tomcat container adds Java 8.

Any thoughts?
