We played around with the „sandcastle“ and tried to build with it containers on podman. The cache grew to over 100GB while building (and we only had 100GB left on the machine). It takes an eternal time and I wonder, why there aren’t ready to use pre-built containers like any other podman/docker project offers them. It would make it so much easier to get to the point to be playing with TALER on your own infrastructure and to understand it better.
Hi, we do have plans to improve the build time (and size requirements) of the sandcastle by making it use our nightly Debian packages to install the components, instead of building from source, as it does currently.
As for publishing prebuilt images, we do not have any plans to do so at the moment, as we are focused on other areas of development and maintenance.
Another avenue you could pursue is installing the Debian packages we publish in a standard Debian base image. See our documentation for instructions on using our apt repo.
