The operating system my web server runs on is (include version):
Ubuntu 18.04 LTS
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I am running Boulder in Docker on an AWS instance.
I am able to make incoming network connections from external addresses. For example, from a different AWS instance, I can connect to Boulder and the OCSP Responder on the appropriate ports.
However, I am NOT able to make outgoing connections from Boulder to an external address, … in particular to an AWS RDS instance running MariaDB.
I am not a Docker expert, so I don’t know what changes are required.
Can anyone suggest how to allow processes running inside Docker to access external IP addresses?
Any help would be appreciated,
