  Artificial gauge fields are versatile tools that allow to influence the
dynamics of ultracold atoms in Bose-Einstein condensates. Here we discuss a
method of artificial gauge field generation stemming from the evanescent fields
of the curved surface of an optical nanofibre. The exponential decay of the
evanescent fields leads to large gradients in the generalized Rabi frequency
and therefore to the presence of geometric vector and scalar potentials. By
solving the Gross-Pitaevskii equation in the presence of the artificial gauge
fields originating from the fundamental HE$_{11}$ mode of the fibre, we show
that vortex rings can be created in a controlled manner. We also calculate the
magnetic fields resulting from the higher order HE$_{21}$, TE$_{01}$, and
TM$_{01}$ modes and compare them to the fundamental HE$_{11}$ mode.
