######## Services ######## The RSTUF API is a service that exposes a web service. By default, the container image exposes port ``80`` or port ``443`` when :ref:`using HTTP certificates `. Depending upon the specific RSTUF use case, it may become necessary to expose these ports externally. The RSTUF Worker is not a service but a workload. No port is exposed. The :ref:`guide/deployment/planning/deployment:Required Infrastructure Services` expose their ports depending upon the deployment. Those services are only required to communicate with the :ref:`guide/general/introduction:RSTUF Components`.
