Hi, We've created a docker hub organisation called "arrowdev" to host the images defined in the docker-compose.yml, see the following commit [1]. So now it is possible to speed up the image builds by pulling the layers first, I suggest to use the --pull flag for building images: `docker-compose build --pull cpp`
We need to manually grant write access for committers and PMC members, so please send me your dockerhub username. Thanks, Krisztian P.S. Github has recently introduced its packaging feature, so we'll be able to experiment with hosting docker images on GitHub directly which would handle our permission settings out of the box. IMO we should try it once it is enabled for the apache/arrow repository. [1]: https://github.com/apache/arrow/commit/1165cdb85b92cefcf59ac39d35f42d168cc64517
