$ docker run --name cron-sendemail --restart always -dt cron-sendemail
⁠Using docker-compose
$ docker-compose build
$ docker-compose up -d
⁠Logs - Whatever you/script write to "/var/log/cron.log" will get redirected to your container logs

⁠sendEmail - SMTP client (This docker image will have sendEmail installed), you can use this optionally in your shell scripts -
$ export [email protected]           ## From addess & user email for authentication
$ export [email protected]
$ export PASSWD_EMAIL=ab12345678
$ export SMTP_EMAIL="smtp.gmail.com:587"
$ export SUBJECT_EMAIL="This should be the email subject"
$ export CONTENT_EMAIL="This is the content/body of email"      ## You can give file as a content
$ sendEmail -u $SUBJECT_EMAIL -m $CONTENT_EMAIL -f $FROM_EMAIL -t $TO_EMAIL -s $SMTP_EMAIL -o tls=yes -xu $FROM_EMAIL -xp $PASSWD

ToDo - Improving sendEmail usage.
