Supporting questions

  • Can we repackage a “thinned-out” module with only select packages?

    • probably:

      • EL8 RPM prereqs: createrepo_c (appstream) + modulemd-tools (epel)

      • Process:

        Code Block
        # Create initial repo with ursine modules
mkdir -p $NEW_REPO_DIR/Packages/ursine
cp "${URSINE_PACKAGE_FILES[@]}" "$NEW_REPO_DIR/Packages/ursine/"
cd "$NEW_REPO_DIR"
createrepo_c .

Modularity CLI examples

Simple dnf module commands

...

Code Block
languagebash
DNF_DLONLY_TARGET_PACKAGE=httpd
DNF_DLONLY_INSTALL_ROOT=/root/fake-install-dir
DNF_DLONLY_PACKAGE_DIR=/root/downloadonly

dnf install --downloadonly \
  --setopt=install_weak_deps=False \
  --installroot="$DNF_DLONLY_INSTALL_ROOT" \
  --downloaddir="$DNF_DLONLY_PACKAGE_DIR" \
  --enablerepo=appstream \
  --disablerepo=test \
  --releasever=8 \
  "$DNF_DLONLY_TARGET_PACKAGE"
Info

Pointing to an empty --installroot= will cause dnf install --downloadonly to download EVERY dependency, including the packages for the baseos.

In this case, --setopt=install_weak_deps=False may be useful to ignore weak RPM dependencies and cut down on the download size.
