-fetch-course-emails
--------------------
-
-This container fetches the campus email addresses of students and instructors
-in specified UCB courses. It runs as a sidecar container alongside hubs
-provisioned by berkeley-dsep-infra/datahub.
-
-Configuration
-=============
-
-Container
-=========
-
-This container is run as a sidecar by specifying it under hub.extraContainers.
-Provide API credentials as environment variables in encrypted configuration (i.e. secrets):
-```
-jupyterhub:
-  hub:
-    extraContainers:
-      - name: fetch-course-emails
-        image: berkeleydsep/fetch-course-emails:v3
-        volumeMounts:
-          # for writing out email lists ; consider new volume
-          - name: pvc
-            mountPath: /srv/jupyterhub
-          # for reading in profiles
-          - name: secret
-            mountPath: /etc/jupyterhub/config
-        env:
-        - name: UCB_HR_ID
-          value: "..."
-        - name: UCB_HR_KEY
-          value: "..."
-        - name: SIS_CLASSES_ID
-          value: "..."
-        - name: SIS_CLASSES_KEY
-          value: "..."
-        - name: SIS_ENROLLMENTS_ID
-          value: "..."
-        - name: SIS_ENROLLMENTS_KEY
-          value: "..."
-        - name: SIS_STUDENTS_ID
-          value: "..."
-        - name: SIS_STUDENTS_KEY
-          value: "..."
-        - name: SIS_TERMS_ID
-          value: "..."
-        - name: SIS_TERMS_KEY
-          value: "..."
-```
-
-Profiles
-========
-Courses are specified as keys of the form {year}-{term}-{class_section_id} in
-the helm config. For example:
-
-```
-custom:
-  profiles:
-    2019-summer-15798: {}
-    2019-spring-25622:
-      mem_limit: 4096M
-      mem_guarantee: 2048M
-```
-
-See https://classes.berkeley.edu for class section IDs.
-
-Output
-======
-The container saves email addresses into files:
-```
-/srv/jupyterhub/profiles.d/{year}-{term}-{class_section_id}-students.txt
-/srv/jupyterhub/profiles.d/{year}-{term}-{class_section_id}-instructors.txt
-```
-which are read by the custom spawner.
