💅 CH-SSH(1) — the Charliecloud manual, bestie edition 🦋

okay so real quick, the manual name is Charliecloud and the page is ch-ssh, and we're on version 0.31 ✨

🌸 NAME 🌸

ch-ssh — run a remote command in a Charliecloud container

✨ SYNOPSIS ✨

$ CH_RUN_ARGS="NEWROOT [ARG...]"
$ ch-ssh [OPTION...] HOST CMD [ARG...]

🎀 DESCRIPTION 🎀

So basically, this runs the command CMD inside a Charliecloud container on the remote host HOST. Slay. It takes the content of the environment variable CH_RUN_ARGS and uses that as the arguments to ch-run over on the remote host. That's the whole vibe.

NOTE, and this one matters: words inside CH_RUN_ARGS are delimited by spaces only. It is not shell syntax. Not quoting rules, not shell escaping, none of that. Space-separated words, periodt. 💀

🌈 EXAMPLE 🌈

Say you're on host bar.example.com and you wanna run the command echo hello inside a Charliecloud container, using the unpacked image at /data/foo with starting directory /baz. It goes a lil something like this:

$ hostname
foo
$ export CH_RUN_ARGS='--cd /baz /data/foo'
$ ch-ssh bar.example.com -- hostname
bar

look at that. foo locally, bar remotely, no cap. 🫶
