You can just expose the ports you need either in the dockerfile used to build the image or on the yaml used to run the pod if you don’t have access to the docker file to rebuild the image . But making sure that the port you are exposing is being used by the apps inside the image may need additional configuration inside your image . Exposing ports does not mean that the apps running inside the image will bind to them …
