Do Travis agent not cache downloaded docker images ?
Drone [1] agents (can) do.

I'm experimenting a drone instance associated with the OSGeo Gogs
instance, and currently using it to build-test postgis/geos,
see for example:
https://git.osgeo.org/gogs/postgis/postgis/src/svn-trunk/.drone.yml

The longest step there for agents is (apart from the very first build)
fetching the sources being tested.
