ajoergensen/baseimage-ubuntu repository overview

⁠Ubuntu baseimage

A baseimage based on Phusion's base image⁠

Bits and pieces have been sourced from other fine Docker images

⁠Environment

• PUID - Changes the uid of the app user, default 911
• PGID - Changes the gid of the app group, default 911
• SMTP_HOST - Change the SMTP relay server used by ssmtp (sendmail)
• SMTP_USER - Username for the SMTP relay server
• SMTP_PASS - Password for the SMTP relay server
• SMTP_PORT - Outgoing SMTP port, default 587
• SMTP_SECURE - Does the SMTP server requires a secure connection, default TRUE if SMTP_USER is set.
• SMTP_TLS - Use STARTTLS, default TRUE (if SMTP_TLS is FALSE and SMTP_SECURE is true, SMTP over SSL will be used)
• SMTP_MASQ - Masquerade outbound emails using this domain, default empty

⁠Email

If you need to send mail and cannot use SMTP directly, ssmtp is installed to provide /usr/bin/sendmail and is configured using the SMTP_ variables.

If SMTP_USER is not set, unauthenticated SMTP will be used and SSL/TLS is disabled.

⁠Persistent data

Generally I store configuration data in /config and store it in a volume. If an application does not permit changing the location of its configuration data, add a script to /etc/my_init.d which changes the app user's $HOME
