protected void addFixedExposedPort(int hostPort, int containerPort) {
        addFixedExposedPort(hostPort, containerPort, InternetProtocol.TCP);

Note that this method is protected scope to discourage use, as clashes or instability are more likely when
using fixed port mappings. If you need to use this method from a test, please use {@link FixedHostPortGenericContainer}
instead of GenericContainer.
