# Felis control-plane image.
|
|
#
|
|
# Builds the panel, then the single multi-call `felis` binary (api / operator /
|
|
# migrate / reaper / restore / manifests / setup) as a static, CGO-free
|
|
# executable and ships it on a distroless base. Two contracts the rendered
|
|
# Deployments depend on:
|
|
#
|
|
# 1. The binary lives at /usr/local/bin/felis, and rendered Kubernetes
|
|
# workloads invoke that absolute path rather than relying on PATH lookup.
|
|
# 2. The image is meant to be imported into a local containerd (k3s ctr import)
|
|
# and referenced by a NON-:latest tag (e.g. felis:demo). k8s then resolves
|
|
# the default IfNotPresent pull policy against the imported image instead of
|
|
# trying to pull it from a registry that does not exist yet.
|
|
#
|
|
# deploy/bootstrap.sh also extracts this same binary onto the host (docker cp)
|
|
# so `felis migrate up` and the `felis setup` TUI run with the identical build.
|
|
|
|
# Both BUILD stages are pinned to the BUILDPLATFORM so a multi-platform buildx run never
|
|
# emulates them: the panel's output is plain JS and identical on every architecture, and the
|
|
# Go stage cross-compiles natively via TARGETARCH below. Under QEMU an `npm ci` alone costs
|
|
# minutes. The FINAL stage is deliberately NOT pinned — it must stay on the target platform
|
|
# or the published arm64 image would carry amd64 layers. It contains only COPY, which
|
|
# BuildKit performs itself, so it needs no QEMU either; adding a RUN there would.
|
|
#
|
|
# Every base image here and in deploy/{limbo,lobby,paper} is pinned by digest, so a rebuild
|
|
# of one release uses the same bytes; .github/dependabot.yml proposes the bumps (tag and
|
|
# digest together).

# `docker build`, or a setup-buildx step that quietly did not take) produces a working amd64
|
|
# binary that gets published under the arm64 name. .github/workflows/release.yml asserts the
|
|
# ELF machine type with file(1) for exactly this reason — an exec-based check cannot catch it,
|
|
# because CI runners have binfmt/QEMU registered and will happily run the wrong one.
