docker ubuntu arm64 Go

After trying multiple solutions online, I still can't figure this out. I've been working on this all day and I'm working on a project and hit a roadblock..... I'm running Docker on an ARM64 architecture Ubuntu 22.04 and I'm having trouble starting my containerized application. After building my Docker image using a multi-stage build, whenever I attempt to run the container, I encounter the following behavior: `standard_init_linux.go:228: exec user process caused: exec format behavior`. Here's the relevant part of my Dockerfile: ```Dockerfile # Stage 1: Build FROM golang:1.18 AS builder WORKDIR /app COPY . . RUN CGO_ENABLED=0 GOOS=linux go build -o myapp ./cmd/myapp # Stage 2: Create a minimal image FROM alpine:latest COPY --from=builder /app/myapp /usr/local/bin/myapp ENTRYPOINT ["/usr/local/bin/myapp"] ``` I suspect the question is related to the architecture, especially since I used the `golang` base image without specifying an architecture. I also checked the architecture of the built binary with `file myapp`, and it returns `ELF 64-bit LSB executable, ARM aarch64`. However, when I try to run the container, it doesn't seem to execute properly. I have verified that I'm using Docker version 20.10.7, and my system is indeed ARM64. To further debug, I tried running a simple Alpine container, and that works fine. I also checked the permissions on my binary and ensured it’s executable. Could this be related to the base image used in the second stage? Should I be using a different base image for ARM64, or is there a specific flag I need to set when building the image? Any insights would be greatly appreciated! Any help would be greatly appreciated! Cheers for any assistance! Cheers for any assistance! Thanks for any help you can provide!
