WORKERS variable not working

[vistalba]

Hi

I use this docker image on kubernets with nodeport setup.

              - name: TZ
                value: "Europe/Berlin"
              - name: SECRET
                value: "secret1,secret2,secret3,secret4"
              - name: SECRET_COUNT
                value: "4"
              - name: TAG
                value: "tag1"
              - name: WORKERS
                value: "4"

If I look on the log output:

Is there anything wrong in my setting or is it just not accepting my "value" for "WORKERS"?
