1. Build multiplatform docker {#r_build_docker}

1.1. Requirements {#r_docker_req}

sudo apt-get install -y docker-ce
sudo apt-get install -y qemu qemu-user-static
sudo apt-get install -y binfmt-support
docker buildx create --use --name mybuilder

Add in your .docker/config.json

{
    "experimental": "enabled"
}

1.2. Build multiplatform python image for old OS {#r_docker_push}

Log to dockerhub :

docker login

Warning :

• first build of ARM image may take up to 2 hours

TAG=3.11.9
docker buildx build -t pich02/python3-glibc2.24:$TAG . -f python-build.dockerfile --progress=plain --platform=linux/amd64,linux/arm/v7,linux/arm64 --push

1.3. Build multi-arch scip

put scip-9.0.0.tgz source inside packages directory

TAG=9.0.0
sudo docker buildx build -t pich02/scip-multi-arch:$TAG . -f scip-build.dockerfile --progress=plain --platform=linux/amd64,linux/arm/v7,linux/arm64 --push

1.4. Build python3 with scip

TAG=3.11.9
docker buildx build -t pich02/python3-glibc2.24:${TAG}-scip . -f python-scip.dockerfile --progress=plain --platform=linux/amd64,linux/arm/v7,linux/arm64 --push

1.5. Déboguer l'image

Run an image :

docker run --name test-debug --entrypoint /bin/sleep pich02/python3-glibc2.24:3.11.9 infinity

Connect to it with :

docker exec -it $(docker ps -aqf "name=test-debug") /bin/bash

1.6. troubleshooting

1.6.1. GCP compute engine

Docker build failed to "apt update"

check mtu

ip addr | grep mtu

mtu of enx3 and docker0 must be the same if not added :

{ "mtu": 1460 }

to /etc/docker/daemon.json
