Not getting a shinyproxy.log in container

I’m not able to get shinyproxy to output a log file for some reason. I’m running shinyproxy in a countainer. When I bash into the container I can’t find it anwhere. However, when I run docker service logs shinyproxy_shinyproxy I get a nice comprehensive log.

proxy:
  title: App Portal
  port: 8080 # use Port 8080 for ShinyProxy
  
  container-wait-time: 30000 # how long should we wait for the container to spin up (30s as default as this is enough for our Shiny apps)
  heartbeat-rate: 10000 # the user's browser will send a heartbeat call every heartbeat-rate milliseconds (10s as default)
  heartbeat-timeout: 60000 # if the server does not receive a heartbeat for heartbeat-timeout milliseconds, the relevant proxy will be released (60s as default)

  #### Set Up Usage Statistics Monitoring
  usage-stats-url: http://influxdb:8086/write?db=shinyproxy_usagestats # use InfluxDB to store usage statistics; can be in a different server
  # usage-stats-username: xxxx # influxdb username if needed
  # usage-stats-password: xxxx # influxdb password if needed

  #### OpenID Connect Authentication ####
  # authentication: openid # use openid auth framework
  # openid:
  #   roles-claim: cognito:groups # use the groups value passed by AWS cognito to identify user groups
  #   auth-url: # https://{cognito_domain_prefix}.auth.{region}.amazoncognito.com/oauth2/authorize
  #   token-url: # https://{cognito_domain_prefix}.auth.{region}.amazoncognito.com/oauth2/token
  #   jwks-url: # https://cognito-idp.{region}.amazonaws.com/{userPoolId}/.well-known/jwks.json
  #   logout-url: # https://{cognito_domain_prefix}.auth.{region}.amazoncognito.com/logout?client_id={client_id}&logout_uri={your_host_url}
  #   client-id:  # get this from AWS Cognito user pool management page
  #   client-secret:  # get this from AWS Cognito user pool management page
