tini isn't needed anymore

[BlinkyStitt]

Docker 1.12+ handles an init process now

[mariusgrigaitis]

Also it does not currently work because of tini

$ pinata-ssh-forward
docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/usr/bin/tini\": stat /usr/bin/tini: no such file or directory".

New location of tini is /sbin/tini, looks like fixed in #7

Could you please explain how Docker 1.12+ handles an init process, any relate document about it?

My docker version is 1.12.5, but init doesn't work with it.

@mariusgrigaitis

Can't make it work with /sbin/tini, tini can't be found (AWS Linux AMI)

https://github.com/docker/docker/blob/master/CHANGELOG.md#runtime-2

Add boolean flag --init on dockerd and on docker run to use tini a zombie-reaping init process as PID 1 #26061 #28037

moby/moby#28037

I actually ended up putting tini back into the image so that we wouldn't have to worry about someone forgetting this flag.
