Updating Portage

Kubler builds images using a Gentoo and Portage. To update Portage run kubler update. After this, to rebuild images with the latest packages run kubler build -c $namespace. For example if you namespace is called bestnamespace run kubler build -c bestnamespace.

Problems with the Builder image(s) after a Portage update

Sometimes after upgrading portage with kubler update problems will occur when trying to rebuild the builder images, such as kubler/bob-musl. To help diagnose and fix the issue you can do an interactive build of the builder images, just like you would for any other image, with kubler build -i $imagename e.g. kubler build -i kubler/bob-musl.

Once you have worked out what the issue is and found a solution (or a workaround) you can modify the builders config and build the image the normal way for a permanent fix. Perhaps commit the changes into a branch in git for tracking work-in-progress or for sharing (e.g. sending a Pull Request (PR))
