Send email on testing docker container with php an

Question

I'm on ubuntu 16.04. I have a (testing) docker (docker-compose) container running php 5.6 and apache 2.4.

With production plateform (without docker) the mail is send with sendmail.

How to send test email on docker container (with sendmail) ?

Thanks in advance for responses.

Answer 1

It works.

In Dockerfile :

# sendmail config
############################################

RUN apt-get install -q -y ssmtp mailutils

# root is the person who gets all mail for userids < 1000
RUN echo "root=[e-mail]" >> /etc/ssmtp/ssmtp.conf

# Here is the gmail configuration (or change it to your private smtp server)
RUN echo "mailhub=smtp.gmail.com:587" >> /etc/ssmtp/ssmtp.conf
RUN echo "AuthUser=[e-mail]" >> /etc/ssmtp/ssmtp.conf
RUN echo "AuthPass=yourGmailPass" >> /etc/ssmtp/ssmtp.conf

RUN echo "UseTLS=YES" >> /etc/ssmtp/ssmtp.conf
RUN echo "UseSTARTTLS=YES" >> /etc/ssmtp/ssmtp.conf


# Set up php sendmail config
RUN echo "sendmail_path=sendmail -i -t" >> /usr/local/etc/php/conf.d/php-sendmail.ini

For testing inside php sendmail container :

echo "Un message de test" | mail -s "sujet de test" [e-mail]
