Multi-architecture Docker images

[gabriel-duque]

Hey,

I have been using chartmuseum to host some charts and have recently moved my infrastructure from x86_64 hosts to armv8 (aarch64) hosts.

Hence, I would like to have the option of using an aarch64 container image but none is available.

Using docker buildx it is pretty easy to build multi-architecture images and it is a breeze using GitHub actions.

I am not sure to what extent this is possible using codefresh as the support for arm builds seems interrupted and is only available for Entreprise customers.

In order for this to work with a Github action, the major thing that would have to be done would be to rewrite the Dockerfile in order to have the build of chartmuseum happen in the container directly. Another advantage of having the Dockerfile rewritten would be building a smaller image by building a static binary and copying it to a "from scratch" image along with the ca-certificates.
