Shared Runners

Since April 2016, partnered with DigitalOcean to provide shared Runners in autoscale mode that are free for all users. Autoscaling means reduced waiting times to spin up builds, and isolated VMs for each project, thus maximizing security.

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 9.1.0 (0118d89) -
Executor docker+machine -
Default Docker image ruby:2.1 -
privileged (run Docker in Docker) true false
