at_dockerfiles was deprecated

This repo was deprecated for a while as it was no longer needed when Arm support found its way into the official Dart Docker image

It's back in order to support the RISC-V instruction set architecture, and as Debian doesn't yet support RISC-V in its stable release it could be some time before there's RISC-V in the official Dart image.

at-buildimage

Our own version of dart that can run on multiple architectures (x86_64, armv7, arm64, riscv64).

Takes a build time ARG - DART_VERSION (defaults to 3.5.2)

Manual build:

DART_VERSION="3.5.2"
ARCH="arm"
sudo docker build -t atsigncompany/buildimage:"$DART_VERSION"-"$ARCH" \
--build-arg DART_VERSION="$DART_VERSION" -f at-buildimage/Dockerfile .

or for RISC-V:

DART_VERSION="3.5.2"
ARCH="riscv"
RISCV64_SHA="db992347d0bab44ec6df1faac25ca73c5e12840e9f3a638cbd6a87d741655f50"
sudo docker build -t atsigncompany/buildimage:"$DART_VERSION"-"$ARCH" \
--build-arg DART_VERSION="$DART_VERSION" \
--build-arg RISCV64_SHA="$RISCV64_SHA" -f at-buildimage/Dockerfile.RV64 .

Available on Dockerhub as atsigncompany/buildimage

NB the regular Dockerfile is just a wrapper around the library Dart official image, used as a stepping stone to constructing the multi platform image with RISC-V. Dockerfile.RV64 mimics the Dockerfile from the library image, with added conditional logic for the riscv64 architecture. For now it is using ubuntu:noble (24.04 LTS) as that distribution has official stable support for RISC-V, which isn't yet available in Debian Stable (12 'Bookworm'). That should change when Debian 13 'Trixie' is released, but at that stage it should be possible to get RISC-V support into the official image and once again deprecate this repo and associated images.

dartshowplatform

Trivial application that prints out version information, including platform.

Used for testing multi stage, multi arch builds.

Manual build:

DART_VERSION="3.5.2"
ARCH="arm"
sudo docker build -t atsigncompany/dartshowplatform:"$DART_VERSION-$ARCH" \
--build-arg IMAGE_TAG="$DART_VERSION-$ARCH" -f dartshowplatform/Dockerfile .

Run:

sudo docker run -it atsigncompany/dartshowplatform:"$DART_VERSION-$ARCH"

Example output:

3.5.2 (stable) (Wed Aug 28 10:01:20 2024 +0000) on "linux_riscv64"

Available on Dockerhub as atsigncompany/dartshowplatform

Automation

There's a single GitHub Actions workflows:

1. autobuildall.yml uses docker_build to build and push at-buildimage and dartshowplatform for amd64, arm, arm64 & riscv64 platforms.
