[Buildah] shell globing with buildah run

16 Feb 2021

      Hi all,

the following buildah script gives me some trouble to understand how to
do it best:

---
image_id=$(buildah from quay.io/centos/centos:stream8)

run="buildah run $image_id --"

set -e

# works fine
$run bash -c 'ls -l /var/cache/* /var/log/*'

# does not work since * is not expanded
$run ls -l "/var/cache/*" "/var/log/*"

# does not work correctly
$run rm -rf /var/cache/* /var/log/*

#neither does
$run rm -rf "/var/cache/*" "/var/log/*"

# this works
$run bash -c 'rm -rf /var/cache/* /var/log/*'

# as can be seen with
$run bash -c 'ls -l /var/cache/ /var/log/'
-----

I am wondering how to correctly do this? using bash -c ? to make sure
the globbing is done within the container and not outside?

best
