I'm curious how people have approached the problem of sending notifications from bash scripts in containers. Do you use email? If so, how have you set it up? Do you include a full MTA in the container just to send notifications? Having tried a number of different ways (installing and configuring either postfix or exim to support sendmail), I am currently using mailx in my containers to send emails to my mail server. This seems to work well and is fairly light weight. Are there better ways of receiving notifications from bash scripts in my containers? Cheers, Graham.
