I discuss D-instanton solutions in type IIB supergravity on AdS5×T1,1, which has a dual N=1 SU(N)×SU(N) super Yang-Mills theory. Apart from ordinary D(-1)-brane instantons, I consider wrapped D1-branes over minimal 2-cycles and derive explicit solutions preserving half the supersymmetries. These solutions are identified with Yang-Mills instantons which are (anti)self-dual in both gauge group factors with instanton charge (k,k′). By examining the boundary behaviour of the solutions I derive the coupling to the corresponding dual boundary operators, and identify their vacuum expectation values. I also discuss the boundary terms and compute the action for these solutions.
