Systemd escaping

[ryansmithevans]

Complex docker run commands create a systemd runscript that doesn't work.
If you're using spaces or quotes or something like this, then you'll get issues with the systemd/system/docker-x.service file.

See https://www.freedesktop.org/software/systemd/man/systemd-escape.html

A better approach would be to run a script that contains the run command. This way any issues are avoided for commands used in docker.

I found a fast bugfix for spaces in environment variables:
If you patch the file

/lib/puppet/parser/functions/docker_run_flags.rb

and find the line
['-e %s', 'env'],
and change that to
['-e "%s"', 'env'],`
the environment variables with spaces work fine.
