Build image and push to ECR
Hello everyone,
I cloned the repo and tried to build a local Docker image:
DOCKER_BUILDKIT=1 docker build --file build/zitadel/Dockerfile . -t zitadel:local
The build consistently fails on this line in the Dockerfile:
6 COPY build/zitadel/entrypoint.sh /app/entrypoint.sh
8 COPY zitadel /app/zitadel <-- fails here
Error:
ERROR: failed to build: failed to solve: failed to compute cache key:
failed to calculate checksum of ref ...: "/zitadel": not found
From reading the Dockerfile, it looks like it expects a prebuilt
I couldn’t find documentation that explains how to produce that binary before the

If there’s an official workflow (e.g., “generate stubs → build binary → docker build” or “use compose/buildx”), plus the recommended way to push to ECR (including multi-arch), I’d really appreciate detailed steps or a doc pointer. Thanks a lot!

1) Is building this image directly with

zitadelzitadel binary that should be copied by COPY zitadel /app/zitadelCOPY zitadel /app/zitadel?3) If not, should I use

linux/amd64,linux/arm64linux/amd64,linux/arm64). Could you share the official / recommended steps or a script (e.g., using
docker buildxdocker buildx + ECR login + manifest) that work with this repo?What I tried
- Ran
go buildgo build from repo root to produce a zitadelzitadel binary, but hit missing generated files (gRPC/OpenAPI) and wasn’t sure about the correct generation step or alternative way to get the binary.- Tried with and without BuildKit; the same error persists because
zitadelzitadel binary doesn’t exist in the build context.- I can use either: (a) prebuild a binary and
COPYCOPY it (method B), or (b) a multi-stage Dockerfile if that’s the supported workflow.If there’s an official workflow (e.g., “generate stubs → build binary → docker build” or “use compose/buildx”), plus the recommended way to push to ECR (including multi-arch), I’d really appreciate detailed steps or a doc pointer. Thanks a lot!
