Support for multiple buildpack volumes
Customer is using the recently added feature to specify volumes via variable BUILDPACK_VOLUMES
. GitLab team members can read more in the ticket.
However, it's not clear how multiple volumes are passed, either
- via
BUILDPACK_VOLUMES
or - via
--volume
to the pack build command. There's no example in the docs or in the parameters summary
Suspicion is that each volume is passed with it's own --volume
parameter.
This being the case, our code won't support this. Contrasting passing --env
and --volume
it's clear that additional steps are needed to effect a loop:
--volume
volume_args=()
if [[ -n "$BUILDPACK_VOLUMES" ]]; then
volume_args=('--volume' "$BUILDPACK_VOLUMES")
fi
--env
env_args=()
if [[ -n "$AUTO_DEVOPS_BUILD_IMAGE_FORWARDED_CI_VARIABLES" ]]; then
mapfile -t env_arg_names < <(echo "$AUTO_DEVOPS_BUILD_IMAGE_FORWARDED_CI_VARIABLES" | tr ',' "\n")
for env_arg_name in "${env_arg_names[@]}"; do
env_args+=('--env' "$env_arg_name")
done
fi
Customer has tried concatenating multiple volumes, with --volume
into BUILDPACK_VOLUMES
but this didn't work.
