FAQ about Stackhero for GitLab Runner cloud

Your runner works with GitLab.com (Free, Premium and Ultimate) and with any self-managed GitLab, including a GitLab you host on Stackhero. You register it once with a runner authentication token, and it starts picking up your jobs.

No. Unlike runners billed per CI/CD minute, your GitLab Runner runs on a dedicated VM you rent by the hour, so your build minutes are unlimited. You can run pipelines 24/7 without ever topping up compute credits.

It depends on your plan, from a single job up to dozens of concurrent jobs. This corresponds to the GitLab Runner concurrent setting: the more concurrent jobs, the more of your pipeline runs in parallel instead of queuing.

The Docker executor. Every job runs in its own clean container based on the image you choose in your .gitlab-ci.yml, so your builds are reproducible and isolated from each other.

Yes. Docker-in-Docker support lets you run docker build and push images to any registry, including the GitLab Container Registry. See the GitLab Runner documentation for a ready-to-use example.

Create a runner authentication token in your GitLab project, group or instance, then paste it into the Stackhero dashboard. Your runner connects on its own. The full walkthrough is in the GitLab Runner documentation.

Since Stackhero provides managed services, SSH access is not available. For any installation needs, please contact support to explore possible solutions.

Absolutely! Your instance has its own firewall where you can decide which IPs have access to which port in just 2 clicks.

We developed our own cloud software solution, making us entirely independent from cloud providers. We deploy this innovative solution directly on bare-metal servers, offering you exceptional performance and stability.

Stackhero is a French company operating under European and French laws.
Servers are located, depending on your choice, either in the European Union (France) or in the USA.
Backups are stored in the European Union.

Your service consists of multiple subservices. All of them run in containers within a virtual machine that is entirely dedicated to you.
This VM is completely private and isolated from other clients, providing a highly secure environment with very high performance.
It is hosted on a bare-metal server running Stackhero DC OS, our own Linux distribution.

We use disks that are physically connected to your instances.
We don't use network disks, unlike traditional cloud solutions, which are slow and costly.
This way, we ensure optimal performance and exceptional IOPS.

The issue with traditional backup systems is that files are saved at different time intervals.
Let's say you have 2 files, a.txt and b.txt. Your backup starts at 9 a.m. and finishes at 10 a.m.
The file a.txt will contain data from 9 a.m. and b.txt will contain data from 10 a.m.
This is common in backup systems and leads to significant consistency issues.

This is why we developed an in-house backup system that captures an atomic image of your instance at a precise moment.
Atomic in the sense that we can guarantee all files in the backup are captured at exactly the same time.
If your backup starts at 9 a.m., all files will have data from 9 a.m. You have a perfectly consistent and reliable backup.

Backups are initially sent to a dedicated server, which verifies and validates the data. Once these checks are approved, the backups are encrypted and archived.
Encryption uses ECDH and Curve25519 as part of the OpenPGP protocol, with a unique key generated for each backup.

At the start of each month, our system calculates the number of hours your services were operational, and a detailed invoice is generated.
You receive a single monthly invoice that consolidates all your services, clearly explained and easy to understand. Your accounting department will love it!

Stackhero's primary mission is to provide a platform that is easy to use, extremely reliable, and highly secure.
A key element in achieving this mission is the annual attainment of the ISO 27001 certification, a globally recognized quality and security label.
This certification, awarded following a rigorous audit conducted by an independent external body, attests to compliance with the strictest international standards in information security.
