Comment 1 for bug 1604447

The vanilla Apache Kafka charm supports a resource_mirror option, but it's a bit cumbersome to use. The Bigtop Kafka charm (https://jujucharms.com/kafka), on the other hand, installs via apt, so an internal apt repository should be sufficient to handle network-restricted deployments, with the caveat that the packages come from the Bigtop repository, so they will need to be added to the mirror.

The Bigtop repository info can be found at https://www.apache.org/dist/bigtop/bigtop-1.1.0/repos/trusty/ with the repo itself being hosted on S3, and you can see what the individual packages are in their nightly build CI: https://ci.bigtop.apache.org/view/Packages/job/Bigtop-trunk-packages/
