  certificates, such as in environments with corporate proxies or secure
  services, you must ensure that the containers trust these certificates. Without
  adding the necessary CA certificates, applications inside your containers may
  encounter failed requests or security warnings when attempting to connect to

  time, you ensure that any containers started
