How to set SMTP Server Container¶
For sending emails from our application we use SMTP server container in separate Kubernetes pod so we need to set some additional settings as permission to be able to send emails from webserver-php-fpm
pod.
For this purpose, we have set RELAY_NETWORKS
ENV variable with all private networks that can be created by docker into /project-base/kubernetes/deployments/smtp-server.yml
for pod of SMTP container (#777), for instance:
image: namshi/smtp:latest
env:
- name: RELAY_NETWORKS
value: :192.168.0.0/16:10.0.0.0/8:172.16.0.0/12
