README

Igor

Igor is a simple command line tool to download Kernel headers for multiple Linux distributions.

Support

• Debian
• Ubuntu
• RHEL
• CentOS
• Fedora
• OpenSUSE Leap
• SLES
• Google Container Optimized OS
• WSL2

Usage

On a host

$ igor download --output /tmp

Inside a container

You need to bind mount a few folders from the host:

• Ubuntu / Debian /etc/apt (if you used a different path, you can use the --apt-config-dir flag)

• RHEL / CentOS / Fedora

  • /etc/yum.repos.d (if you used a different path, you can use the --yum-repos-dir flag)
  • /etc/pki
  • /etc/rhsm (for RHEL with an active subscription)

• OpenSUSE

  • /etc/zypp (if you used a different path, you can use the --yum-repos-dir flag)

Building

Requirements

Both APT and Container Optimized OS use pure Golang implementationns.

To support RPM based distributions, you need libdnf. On Fedora, simply use dnf install libdnf-devel. To target machines that do not have libdnf, an omnibus project is available here.

Compilation

$ go build -tags dnf

If you used the omnibus method described above, you should use:

$ PKG_CONFIG_PATH=/opt/igor/embedded/lib/pkgconfig CGO_LDFLAGS="-Wl,-rpath,/opt/igor/embedded/lib" go build -tags dnf

Testing

Tests are using the Molecule framework.

To run the tests, you can either:

• Compile the Igor dependencies using omnibus as described in Requirements.
• Download a precompiled version of it here. You then need to decompress it in your local Igor repository folder.

To run the tests for Debian, simply run in the tests folder:

$ molecule test -s debian

You can also run the tests for centos, debian, opensuse and ubuntu.
