atsign-company / at_dockerfiles Goto Github PK

Describe the solution you'd like
Now that the official Dart image has support for Arm we no longer need our own build image.

The entire at_buildimage Dockerfile can now be replaced by FROM dart and at_dartshowplatform can be modified:

-FROM atsigncompany/buildimage:$IMAGE_TAG AS build
+FROM dart AS build

Describe the bug

Since introducing branch protection on main GitHub actions are no longer able to push to that branch

Expected behavior

Need to automate raising a PR instead

Hi,

I am trying to build docker images on an amd64 host where the images built are for arm64 targets (raspberry pi) and so I have come across this github project.

With my current configs, although the build/push to docker process works, the running of the docker image on an arm64 target itself fails.

The Dockerfile for the project I have written as follows:

FROM atsigncompany/buildimage:automated AS build
WORKDIR /app
COPY pubspec.yaml .
COPY lib lib/
COPY bin/main.dart bin/
RUN dart pub get
RUN dart compile exe /app/bin/main.dart -o /app/main.exe

FROM atsigncompany/runimage
COPY --from=build /runtime/ /
COPY --from=0 /app/main.exe /app/main.exe
ENTRYPOINT ["/app/main.exe"]

And the docker build and push part from an amd64 host to a docker registry I am doing like this:

$ docker build . -t registry:50005/projectGroup/projectName:1.0.0-BUILD-x-arm
$ docker push registry:50005/projectGroup/projectName:1.0.0-BUILD-x-arm

But then, in an arm64 target, when I run:

$ docker run -it registry:50005/projectGroup/projectName:1.0.0-BUILD-x-arm

I get:

Status: Downloaded newer image for registry:50005/projectGroup/projectName:1.0.0-BUILD-x-arm
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
standard_init_linux.go:219: exec user process caused: exec format error

What am I missing in order to successfully build an arm64 image for arm64 targets from within an amd64 host? Do I need to specify that the target is arm64 somewhere?

I should point out that docker itself is very new to me so not familiar with its ins and outs...

Thanks in advance,
PM
