The sources of galactic charged cosmic rays are so far unknown, because their arrival directions are randomized in the galactic magnetic field. Objects accelerating hadrons are expected to produce high-energy neutrinos. In addition, a diffuse galactic neutrino flux is predicted from interactions of galactic cosmic rays with matter during propagation through the galaxy. The IceCube neutrino observatory at the geographic South Pole instruments a cubic kilometer of ice with optical modules to detect the Cherenkov light of particles produced in neutrino interactions. Operating for more than a decade in its complete detector configuration, IceCube is in a unique position to search for neutrino sources. This contribution discusses the searches for a diffuse flux of neutrinos as wells as for neutrinos from candidate point sources and extended sources in the galactic plane.
