* ci(eks-ami): build on self-hosted ci-single-1 runner
GitHub-hosted ubuntu-24.04 cannot run the libguestfs appliance network:
passt fails (PID file denied under its AppArmor confine / privilege drop)
and the SLIRP fallback has no outbound, so virt-customize --network dies.
The self-hosted ci-single-1 runner has /dev/kvm and real networking, so
the existing libguestfs build works unmodified.
* fix(build-system-image): add --no-cache, force fresh build on publish
The <10min cached-raw skip avoids duplicate work for concurrent e2e
jobs, but on the persistent publish runner it could republish a stale
image from a prior or concurrent run. Add --no-cache to bypass the skip
and have publish-system-image.sh pass it on every build.
* ci(eks-ami): target ci-single label (no ci-single-1 label exists)
The self-hosted runners are named ci-single/-2/-3 but all share the
single label 'ci-single'; runs-on matches labels, not names, so
ci-single-1 never schedules.
* ci(eks-ami): disable Go cache on self-hosted runner
setup-go's cache-save (Post Setup Go) re-uploaded the Go cache to the
Actions backend on every run, taking ~2.5min vs the 36s build. The
self-hosted runner already keeps the cache on local disk, so cache:false.
* feat(eks): publish eks-node AMI to R2 + spx catalogue entry
Add a spinifex-eks-node catalogue entry so operators install the EKS
node image with a single command:
spx admin images import --name spinifex-eks-node
The entry pulls the Alpine+K3s image from iso.mulgadc.com, verifies its
sha256, and stamps spinifex:managed-by=eks — the tag the control-plane
and node-group launchers resolve the boot AMI by, so no extra config is
needed.
Add scripts/publish-system-image.sh (+ make publish-eks-node-image) to
convert the built raw to a compressed qcow2, emit a checksum sidecar,
and upload both to the R2 bucket backing iso.mulgadc.com/system-ami via
the S3 API.
* ci(eks): add manual workflow to build + publish eks-node AMI to R2
Build the eks-node AMI on the runner (libguestfs) and publish via
publish-system-image.sh using the existing CF_R2_* secrets. Manual
workflow_dispatch with a dry-run input. Fix the publish script's default
bucket to spinifex-iso (the bucket iso.mulgadc.com is served from).
