Mail configuration sends emails from the domain via Mailgun and has its own dedicated IP address (

Alternative SSH port can be reached via a different SSH port for git+ssh.

Setting Value
Port 443

An example ~/.ssh/config is the following:

  User git
  Port 443
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/gitlab

GitLab Pages

Below are the settings for GitLab Pages.

Setting Default
Domain name -
IP address -
Custom domains support yes no
TLS certificates support yes no

The maximum size of your Pages site is regulated by the artifacts maximum size which is part of GitLab CI.

GitLab CI

Below are the current settings regarding GitLab CI.

Setting Default
Artifacts maximum size 1G 100M

Shared Runners

Shared Runners on run in autoscale mode and powered by DigitalOcean. Autoscaling means reduced waiting times to spin up builds, and isolated VMs for each project, thus maximizing security.

They're free to use for public open source projects and limited to 2000 CI minutes per month per group for private projects. Read about all plans.

All your builds run on 2GB (RAM) ephemeral instances, with CoreOS and the latest Docker Engine installed. The default region of the VMs is NYC.

Below are the shared Runners settings.

Setting Default
GitLab Runner 9.2.0 (adfc387) -
Executor docker+machine -
Default Docker image ruby:2.1 -
privileged (run Docker in Docker) true false
