How to use this image
Now you can get access to fpm running on port 9000 inside the container. If you want to access it from the Internets, we recommend using a reverse proxy in front. You can find more information on that on the docker-compose section.
The following environment variables are also honored for configuring your Known instance:
• -e KNOWN_DB_HOST=... (defaults to the IP and port of the linked mysql container) • -e KNOWN_DB_USER=... (defaults to "root") • -e KNOWN_DB_PASSWORD=... (defaults to the value of the MYSQL_ROOT_PASSWORD environment variable from the linked mysql container) • -e KNOWN_DB_NAME=... (defaults to "known") • -e MAIL_HOST=... • -e MAIL_PORT=... • -e MAIL_SECURE=... ("starttls" for instance) • -e MAIL_USER=... • -e MAIL_PASS=...
If the KNOWN_DB_NAME specified does not already exist on the given MySQL server, it will be created automatically upon startup of the known container, provided that the KNOWN_DB_USER specified has the necessary permissions to create it.
If you'd like to use an external database instead of a linked mysql container, specify the hostname and port with KNOWN_DB_HOST along with the password in KNOWN_DB_PASSWORD and the username in KNOWN_DB_USER (if it is something other than root):
Via docker-compose
