at_dockerfiles is deprecated again

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 was brought back to support the RISC-V instruction set architecture, but now that the official Dart image has riscv64 builds it's no longer needed.

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 .

Available on Dockerhub as atsigncompany/buildimage

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

valgrind

A container meant to be run locally which contains Linux only tools for C development. Useful for development, memcheck testing, and debugging on MacOS and Windows.

Run an ephemeral container for tests:

PROJECT_DIR="$PWD" # change to your project's working directory
docker run --rm --platform linux/amd64 \
  --mount type=bind,src=$PROJECT_DIR,dst=/mnt/workdir \
  --mount type=bind,src=$HOME/.atsign/keys,dst=/root/.atsign/keys \
  atsigncompany/valgrind:latest \
  <your test command>

Run a persistent shell in the container:

PROJECT_DIR="$PWD" # change to your project's working directory
docker run --rm --platform linux/amd64 -ti \
  --mount type=bind,src=$PROJECT_DIR,dst=/mnt/workdir \
  --mount type=bind,src=$HOME/.atsign/keys,dst=/root/.atsign/keys \
  atsigncompany/valgrind:latest \
  /bin/bash

Available on Dockerhub as atsigncompany/valgrind

Automation

There are two GitHub Actions workflows:

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

2. valgrind.yml uses docker_build to build and push the valgrind image for amd64, arm & arm64 platforms.
