Docker: comstrek/air doesn’t supported linux/arm64 in golang with Macbook M1 (Solved)

Preface

I want to build golang application with docker and installing library live reload apps with comsrek/air . And I use Macbook M1.

My dockerfile like this:

FROM golang:1.16
ENV FILE_LOC=./.dev/.gql.air.toml
ENV GROUP=company
ENV SERVICE=my-service
RUN apt update && apt upgrade -y && \ apt install -y git \ make openssh-client
WORKDIR /go/src/github.com/${GROUP}/${SERVICE}
RUN curl -fLo install.sh https://raw.githubusercontent.com/cosmtrek/air/master/install.sh \ && chmod +x install.sh && sh install.sh && cp ./bin/air /bin/air
CMD air -c $FILE_LOC

Problem

When I run the dockerfile, I got this error when trying to install comstrek/air:

ERROR [4/4] RUN curl -fLo install.sh https://raw.githubusercontent.com/cosmtrek/air/master/install.sh     && chmod +x install.sh && sh install.sh && cp  0.7s

The problem is the docker was build images with arch linux/arm64 but the library comstrek/air not supported linux/arm64 for currently.

There are supported arch in comstrek/air:

darwin/amd64) BINARIES="air" ;;    darwin/arm64) BINARIES="air" ;;    linux/386) BINARIES="air" ;;    linux/amd64) BINARIES="air" ;;    windows/386) BINARIES="air" ;;    windows/amd64) BINARIES="air" ;;

Installation script: https://github.com/cosmtrek/air/blob/master/install.sh

Known Issue

Docker: Not all images are available for ARM64 architecture. You can add --platform linux/amd64 to run an Intel image under emulation. In particular, the mysql image is not available for ARM64. You can work around this issue by using a mariadb image. — https://docs.docker.com/docker-for-mac/apple-silicon/

Solving

As docker says. I should setup the dockerfile to build with linux/amd64 (one of supported arch). And I change the dockerfile like this:

FROM --platform=linux/amd64 golang:1.16

And your images will be arch with linux/amd64 . And the application also running.

Nice ! Have a great time !
