  This work is devoted to study the analytical and regular solutions of a
particular self-gravitating object (i.e., gravastar) in a particular theory of
gravity. We derive the corresponding field equations in the presence of
effective energy momentum tensor associated with the perfect fluid
configuration of a spherical system. We then describe the mathematical
formulations of the three respective regions i.e., inner, shell and exterior of
a gravastar separately. Additionally, the significance and physical
characteristics along with the graphical representation of gravastars are
discussed in detail. It is seen that under some specific constraints,
$f(R,T,R_{\mu\nu}T^{\mu\nu})$ gravity is likely to host gravastars.
