Dear All,

I am installing ssh and openrc in an Alpine based docker (8-alpine). To run
ssh as a service, I wanted to use openrc. However, if I simply add "apk add
openrc --no-cache" to my docker file, I get a bunch of error messages (see
below) when running the container with the new image (I use a precomputed
init script  in which I run 'openrc boot' and then 'openrc -s sshd start')

If I include all the additional - not very clear- code from here
https://github.com/dockage/alpine-openrc/blob/master/Dockerfile, things
seem to be working fine.

However, we would like to keep our Docker file clean without a great amount
of unclear code. So I am wondering if there is any straight-forward way to
install openssh, then a service manager tool that starts it upon booting.

Thanks,

Gabor

Thing is, most service managers have to be PID 1. It should work if you
take that into consideration.
