In a future + release we will add the ability to the autoscaler which will enable + the pre-warming of virtual machines. This will significantly reduce + the time it takes to provision a VM on the Windows fleet. You can + follow along in this + [issue](https://gitlab.com/gitlab-org/ci-cd/custom-executor-drivers/autoscaler/issues/32). +- The Windows Shared Runner fleet may be unavailable occasionally + for maintenance or updates. +- The Windows Shared Runner virtual machine instances do not use the + GitLab Docker executor. This means that unlike the Linux Shared + Runners, you will not be able to specify `image` and `services` in + your pipeline configuration. +- For the beta release, we have included a set of software packages in + the base VM image. If your CI job requires additional software that's + not included in this list, then you will need to add installation + commands to [`before_script`](../../ci/yaml/README.md#before_script-and-after_script) or [`script`](../../ci/yaml/README.md#script) to install the required + software. Note that each job runs on a new VM instance, so the + installation of additional software packages needs to be repeated for + each job in your pipeline. +- The job may stay in a pending state for longer than the + Linux shared Runners. +- There is the possibility that we introduce breaking changes which will + require updates to pipelines that are using the Windows Shared Runner + fleet. + ## Sidekiq GitLab.com runs [Sidekiq](https://sidekiq.org) with arguments `--timeout=4 --concurrency=4` |
