Wails v3 replaces the NPM-only dev entry point. This adds the Go module, Taskfile, build metadata, and a minimal window shell without touching frontend logic. Co-authored-by: Cursor <cursoragent@cursor.com>

# Multi-stage build for a minimal image.

# Defaults produce a pure-Go, fully static binary on a distroless/static base:
|
|
# the smallest, most secure image, and correct for the default (CGO-free) app.
|
|
#
|
|
# If your app needs CGO, override the build args, e.g.:
|
|
# docker build --build-arg CGO_ENABLED=1 \
|
|
# --build-arg GO_IMAGE=golang:bookworm \
|
|
# --build-arg RUNTIME_IMAGE=gcr.io/distroless/base-debian12 \
|
|
# -f build/docker/Dockerfile.server .
|
|
# CGO needs a C toolchain in the builder and a libc in the runtime image; keep
|
|
# the builder and runtime libc compatible (a glibc builder -> a glibc runtime).
|
|
# The Taskfile passes these through: task build:docker CGO_ENABLED=1 GO_IMAGE=... RUNTIME_IMAGE=...
