 Posted: Fri Dec 20, 2024 10:38 am Post subject: Struggling to fix k3s ebuild |
 |
|
I'm attempting to fix a sys-cluster/k3s ebuild and I'm struggling.
What started as an attempt to add missing architectures support for k3s ebuild turned out to be bigger than that.
After adding arm64 support I realised it doesn't work even for amd64.
Be aware this is fairly involved ebuild and I'm new to this.
A diff between my attempt and an existing ebuild:
| Code: | # diff k3s-1.25.4_p1.ebuild ../../../gentoo/sys-cluster/k3s/k3s-1.25.4_p1.ebuild

> K3S_CONTAINERD_VERSION=1.6.8-k3s1
> K3S_RUNC_VERSION=v1.1.4

The problem I have with this now is in src_install.
Turns out k3s-killall.sh (and other scripts ebuild looks for in $FILESDIR) are not installed to the $FILESDIR (/var/tmp/portage/portage/sys-cluster/k3s-1.25.4_p1/files/) directory but to /usr/portage/sys-cluster/k3s/files/
Should I point ebuild to /usr/portage or try and make it copy to $FILESDIR in the first place? If so, how?
I'm sure there are more issues with this ebuild I can't see yet, please tell. |

I don't understand. For example, if you say this in the ebuild:
| erg_samowzbudnik wrote: | | Code: | | newbin "${FILESDIR}/k3s-killall.sh" k3s-killal |
|
you are providing k3s-killall.sh in $FILESDIR, and want it installed in /usr/bin (by default) with the name k3s-killall. Is this not what happens?

If you make a new repository for an ebuild from an existing Gentoo ebuild, you must copy (or otherwise provide) all the relevant items from under the Gentoo repos files directory where the original repository resides to the new location's files directory.
$FILESDIR refers to that "files" directory from wherever the running ebuild is read from. The portage setup process ensures the ebuild has the access it needs to it. |

grknight: this
So turns out this ebuild does work. I managed to install k3s with it.
With caveats:
1.) Binary is now k3s-arm64 witch makes service crash on start. Manually changing binary name in /etc/init.d/k3s fixes that, suppose I could create a symlink, but those are not ideal solutions.
2.) I was expecting something like /etc/k3s/k3s.yaml - but it's not there. Not a big one problem
I wonder if those versions of components are ok though. I just pulled them off the go.mod package from k3s repo. This did not contain `traefik` and `cniplugins` so I left them as they were.
I don't consider this OK - but have trouble finding them so far. |
