The official golang images set GOTOOLCHAIN=local, so a base older than the
governing go.mod `go` directive fails hard instead of fetching a toolchain:
go: go.mod requires go >= 1.26.5 (running go 1.26.4; GOTOOLCHAIN=local)
docker/Dockerfile.multi-node sat on golang:1.24.5-alpine, two minor versions
under the root go.mod floor of 1.26.4. Dockerfile, deploy/testnet/Dockerfile
and Dockerfile.dvenue were at 1.26.4 — exactly at the floor, with no headroom.
Two orthogonal halves:
1. pin every Go builder base to the latest stable patch, 1.26.5, so the
images carry current compiler and stdlib security fixes;
2. set GOTOOLCHAIN=auto in every Go builder stage, so a future floor bump
downloads a checksum-verified toolchain rather than hard-failing.
Dockerfile and deploy/testnet already had it; multi-node and dvenue
did not.
Half 2 is not hypothetical here: sdk/lx-trading-go/go.mod already declares
go 1.26.5, above the root module's 1.26.4, so a submodule build under
GOTOOLCHAIN=local would die at exactly this error.
The root `go` directive stays at 1.26.4 on purpose — raising it pushes a hard
patch-level floor onto every consumer. A newer toolchain building an older
directive is always valid.
docs/Dockerfile is untouched: it builds static docs and compiles no Go.

# dexd-testnet — the multi-node testnet image (CPU, pure-Go, native arch).
|
|
#
|
|
# Builds BOTH binaries the testnet needs from this repo:
|
|
# /usr/local/bin/dexd — the D-Chain venue (cmd/dexd, `dexd run`)
|
|
# /usr/local/bin/dexbench — the signed-ZAP load-gen + cross-arch determinism
|
|
# checker (cmd/dexbench)
|
|
#
|
|
# CGO_ENABLED=0 → pkg/lx's pure-Go CPU matcher (the !cgo build tag). No CUDA, no
|
|
# MLX — so this ONE image builds and runs natively on BOTH boxes:
|
|
# evo = linux/amd64 (WSL) spark = linux/arm64
|
|
# The build does NOT cross-compile: GOARCH defaults to the build host's arch, so
|
|
# `docker build` on each box yields that box's native image. The ZAP wire is a
|
|
# frozen big-endian codec (pkg/zapwire), byte-identical on amd64⇄arm64, which is
|
|
# what makes the cross-arch venue fleet sound (prove it with `dexbench -verify`).
|
|
#
|
|
# GPU NOTE: the GPU matcher (CGO_ENABLED=1) is arm64+CUDA only and lives in
|
|
# Dockerfile.dvenue (spark only, needs the private luxcpp dep tarball). The CPU
|
|
# image here is the canonical, portable testnet path; see README.md "GPU".
|

# ---------------------------------------------------------------------------

|
# Must be >= the `go` directive in go.mod (1.26.4); pinned to the latest stable

# patch so the image ships current compiler/stdlib security fixes. GOTOOLCHAIN
