Doc

Run the application

npm install
npm start

Test the application

curl localhost:3000/

Configure the buildx builder

docker buildx create --name mybuilder
docker buildx use mybuilder

Verify the builder

docker buildx inspect --bootstrap

Login on your docker registry.

ex for docker hub:

docker login

Execute the build with the argument: -t YOURREGISTRY/APPNAME:TAG

ex:

docker buildx build --platform linux/amd64,linux/arm64 -t gustavoapolinario/mult-platform-container:latest --push .

The command below will show informations about the image.

docker buildx imagetools inspect gustavoapolinario/mult-platform-container:latest

To be simple, let's get only the Platform from result:

docker buildx imagetools inspect gustavoapolinario/mult-platform-container:latest | grep Platform

The result:

  Platform:    linux/amd64
  Platform:    linux/arm64

You can see in docker hub the OS/ARCH supported by the image.

Go to your docker hub repository, select your app, click on the tag. The link will send you to a page with a combobox showing the image supported OS/ARCH.
