docker run --name cb -d \
   -e KB_AUTH_TOKEN \
   -e KB_ADMIN_AUTH_TOKEN \
   -e KB_BASE_URL=https://ci.kbase.us/services \
   -e CALLBACK_PORT=9999 \
   -e JOB_DIR \
   -v $JOB_DIR:$JOB_DIR \
   -v /var/run/docker.sock:/run/docker.sock \
   -p 9999:9999 \
   ghcr.io/kbase/jobrunner:latest-rc

auth token, admin auth token, job dir look like they need values
