Required packages on remote

Python (installed with pip for user adrien):

• docker
• docker-compose
• pymysql

TODO: Ansible task to install that before the rest

Configure mailing

When I send mails from the container with php, with current msmtp config, it fails if the recipient isn't @luxeylab.net.

Host mail.log:

Good docs on the topic:

• Explains postfix on Host+ssmtp in Docker in detail, poorly written
• Another one

I needed to add Docker's network (172.0.0.0/8) to mynetworks in /etc/postfix/main.cf. Also inet_interfaces would have had to be changed if Arthur didn't put it to all.

Now solved.
