  We study the interplay between the anisotropy of the dipole-dipole
interaction and confinement in a curved geometry by means of the extended
Gross-Pitaevskii equation, which allows us to characterize the ground state of
a dipolar Bose gas under the confinement of a bubble trapping potential. We do
so in terms of the scattering length a and the number of particles. We observe
the emergence of a wide variety of dipolar solids, consisting on arrangements
of different number of droplets along a ring over the equator of the spherical
shell confinement. We also show that the transition between the different
phases of the system can be engineered by varying a, the number of particles or
the radius of the trap, parameters which can be experimentally tuned. Finally,
we show the importance of working in microgravity conditions as gravity
unstabilizes the observed dipolar solids.
