Using CDash in conjunction with Traefik

[martin5233]

Bug report

Expected Behavior

After startup, the cdash container should be marked as healthy

Actual Behavior

After startup, the cdash container is always marked as unhealthy.

CDash Version

3.5.0rc1

Additional Information

After #2179 was closed I had hoped to finally be able to use CDash in conjunction with Traefik for certificate management again (we still use 2.6.0, because all later versions failed for us). I found the health check tries to also check the HTTPS connection, but with the wrong URL https://cdash:8080. When a container is marked as unhealthy Traefik refuses to export it.

Please either remove the wrong health check for SSL completely or use the address APP_URL from the .env file.
