With any deviation, you're introducing +a layer of complexity that will add challenges to finding out where potential +issues might lie. + +The reference architectures use the official GitLab Linux packages (Omnibus +GitLab) to install and configure the various components (with one notable exception being the suggested select Cloud Native installation method described below). The components are +installed on separate machines (virtualized or bare metal), with machine hardware +requirements listed in the "Configuration" column and equivalent VM standard sizes listed +in GCP/AWS/Azure columns of each [available reference architecture](#available-reference-architectures). + +Running components on Docker (including Compose) with the same specs should be fine, as Docker is well known in terms of support. +However, it is still an additional layer and may still add some support complexities, such as not being able to run `strace` easily in containers. + +Other technologies, like [Docker swarm](https://docs.docker.com/engine/swarm/) +are not officially supported, but can be implemented at your own risk.
