Hello I'm trying to run the following command in my container
mail -s "This is Subject" firstname.lastname@example.org < /path/to/file
How should my dockerfile look so the above command can be executed ?
I tried the following solution
FROM ubuntu:latest ENV DEBIAN_FRONTEND="noninteractive" RUN apt-get update && apt-get install -y mailutils
but I get this error
The command '/bin/sh -c apt-get update && apt-get install -y mailutils' returned a non-zero code: 100
I also tried some examples like this
FROM ubuntu:14.04 RUN apt-get update RUN apt-get install -y mailutils RUN echo "postfix postfix/mailname string gmail.com" | debconf-set-selections RUN echo "postfix postfix/main_mailer_type string 'Internet Site'" | debconf-set-selections RUN apt-get install -y postfix ADD mail.sh /mail.sh RUN chmod +x /mail.sh ENTRYPOINT ["/mail.sh"]
But I don't won't the container to only send emails because I'm customizing a specific container and I just want to enable the sending email features.
