Docker Hub Tools

A tiny Docker image with a set of Bash scripts for:

1. Installing Docker and enabling the experimental mode.
2. Building and tagging multi-platform Docker images.
3. Pushing README file to Docker Hub.

Getting the script

Create a container and copy the scripts file from it.

id=$(docker create moikot/docker-tools)
docker cp $id:/scripts.sh /tmp/scripts.sh && docker rm -v $id
