Docker image does not contain sendmail
Summary
The latest Docker image for GitLab 9.4.1 (gitlab-ce@6678b4e5a64696f70f88345f1b9d93def9912fa2) lacks the /usr/sbin/sendmail
binary, which is required to send mails using the default method.
Steps to reproduce
-
Deploy with docker-compose, using the
docker-compose.yml
provided in the doc. -
Unomment the following lines in
gitlab.rb
:
gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = 'example@example.com'
gitlab_rails['gitlab_email_display_name'] = 'Example'
gitlab_rails['gitlab_email_reply_to'] = 'noreply@example.com'
gitlab_rails['gitlab_email_subject_suffix'] = ''
- Enter the console (
docker exec -it gitlab_web_1 gitlab-rails console
), send a test mail as explained here:
irb(main):003:0> Notify.test_email('destination_email@address.com', 'Message Subject', 'Message Body').deliver_now
What is the current bug behavior?
The previous command returns:
Notify#test_email: processed outbound mail in 1291.4ms
sh: 1: /usr/sbin/sendmail: not found
and the mail never reaches its destination.
What is the expected correct behavior?
/usr/sbin/sendmail
exists in the Docker image, and the mail reaches its destination.

gitlab-shell self-check fails. Although this might be another issue with the Docker image, I don’t believe it is responsible for the missing sendmail binary.
