@ -71,14 +71,37 @@ configured to be used during the build. The call syntax is the following:
makecontainerpkg [cre args] --- [makepkg args]
```
Set the environment variable `CRE` to the container runtime executable (by
default `docker`) and set `CRE_IMAGE` to use a different container image.
Example where the host pacman cache and ccache directories are mounted into the
container and a package rebuild is forced via `makepkg`'s flag `-f`:
```
makecontainerpkg -v /var/cache/pacman/pkg/ -v /run/media/devel/ccache:/ccache -- -f CCACHE_DIR=/ccache
```
Set the environment variable `CRE` to the container runtime executable (by
default `docker`) and set `CRE_IMAGE` to use a different container image.
Example using podman on a non-Arch system:
```
CRE=podman ../../devel/container/makecontainerpkg -v /hdd/cache/pacman/pkg:/var/cache/pacman/pkg -v /hdd/chroot/remote-config-x86_64:/cfg
```
It makes still sense to specify a cache directory, even though pacman is not
used on the host system. Here also a directory containing a custom `pacman.conf`
and `makepkg.conf` is mounted into the container.
### Podman-specific remarks
To use podman (instead of Docker) simply set `export CRE=podman`.
To be able to run podman without root, you need to ensure user/group IDs can be
mapped. The mapping is configured in the files `/etc/subuid` and `/etc/subgid`.
Use `sudo usermod --add-subuids 200000-205000 --add-subgids 200000-205000 $USER`
to configure it for the current user and the configuration via
`grep $USER /etc/sub{u,g}id`.
To change storage paths so e.g. containers are stored at a different location,
edit `~/.config/containers/storage.conf` (or `/etc/containers/storage.conf` for
system-wide configuration) to set `runroot` and `graphroot` to different
locations.
