Informations about taiga and docker

[chadyred]

Hello,

I just finish to install taiga with docker. I am new user of docker. So I have questions:

• taiga data are saving in /data/postgres folder in host when I use taiga in docker guest (so the container). If I remove my postgres container, and I restart it, is there a risk to loose data? How can I save Postgres data?
• Is their a possibility of using port 80 with nginx and taiga? Because if I let nginx started, a message prompt to me and say it's not possible to use this port when I launch it...How can I use Nginx with taiga?
• The email are not sending and is visible when I do "docker taiga-back logs" and we show them. Is their a way to install Postfix or use it in another container in dependencie with taiga-back ?

I use this issue but nothing change. I also install postfix on the container, and I can send mail...but nothing to do, email keep in "docker logs taiga-back". IN LOGS I HAVE THIS:

• The invitations are on the 9001 port, I change it to 80 but why 9001 ?

Many thanks ;)
