Requirements for Auto DevOps
You can set up Auto DevOps for Kubernetes or Amazon Elastic Container Service (ECS). For more information about Auto DevOps, see the main Auto DevOps page or the quick start guide.
Auto DevOps requirements for Kubernetes
To make full use of Auto DevOps with Kubernetes, you need:
Kubernetes (for Auto Review Apps, Auto Deploy, and Auto Monitoring)
To enable deployments, you need:
- A Kubernetes 1.12+ cluster for your project. The easiest way is to create a new cluster using the GitLab UI. For Kubernetes 1.16+ clusters, you must perform additional configuration for Auto Deploy for Kubernetes 1.16+.
NGINX Ingress. You can deploy it to your Kubernetes cluster by installing the GitLab-managed app for Ingress, after configuring GitLab’s Kubernetes integration in the previous step.
Alternatively, you can use the
nginx-ingressHelm chart to install Ingress manually.Note: If you use your own Ingress instead of the one provided by GitLab’s managed apps, ensure you’re running at least version 0.9.0 of NGINX Ingress and enable Prometheus metrics for the response metrics to appear. You must also annotate the NGINX Ingress deployment to be scraped by Prometheus using
Base domain (for Auto Review Apps, Auto Deploy, and Auto Monitoring)
You need a domain configured with wildcard DNS, which all of your Auto DevOps applications will use. If you’re using the GitLab-managed app for Ingress, the URL endpoint is automatically configured for you.
You must also specify the Auto DevOps base domain.
GitLab Runner (for all stages)
Your Runner must be configured to run Docker, usually with either the Docker or Kubernetes executors, with privileged mode enabled. The Runners don’t need to be installed in the Kubernetes cluster, but the Kubernetes executor is easy to use and automatically autoscales. You can configure Docker-based Runners to autoscale as well, using Docker Machine.
If you’ve configured GitLab’s Kubernetes integration in the first step, you can deploy it to your cluster by installing the GitLab-managed app for GitLab Runner.
Runners should be registered as shared Runners for the entire GitLab instance, or specific Runners that are assigned to specific projects (the default if you’ve installed the GitLab Runner managed application).
Prometheus (for Auto Monitoring)
To enable Auto Monitoring, you need Prometheus installed either inside or outside your cluster, and configured to scrape your Kubernetes cluster. If you’ve configured GitLab’s Kubernetes integration, you can deploy it to your cluster by installing the GitLab-managed app for Prometheus.
The Prometheus service integration must be enabled for the project, or enabled as a default service template for the entire GitLab installation.
To get response metrics (in addition to system metrics), you must configure Prometheus to monitor NGINX.
cert-manager (optional, for TLS/HTTPS)
To enable HTTPS endpoints for your application, you must install cert-manager, a native Kubernetes certificate management controller that helps with issuing certificates. Installing cert-manager on your cluster issues a Let’s Encrypt certificate and ensures the certificates are valid and up-to-date. If you’ve configured GitLab’s Kubernetes integration, you can deploy it to your cluster by installing the GitLab-managed app for cert-manager.
If you don’t have Kubernetes or Prometheus installed, then Auto Review Apps, Auto Deploy, and Auto Monitoring are skipped.
After all requirements are met, you can enable Auto DevOps.
Auto DevOps requirements for Amazon ECS
You can choose to target AWS ECS as a deployment platform instead of using Kubernetes.
To get started on Auto DevOps to AWS ECS, you’ll have to add a specific Environment Variable. To do so, follow these steps:
In your project, go to Settings > CI / CD and expand the Variables section.
Specify which AWS platform to target during the Auto DevOps deployment by adding the
AUTO_DEVOPS_PLATFORM_TARGETvariable with one of the following values:
FARGATEif the service you’re targeting must be of launch type FARGATE.
ECSif you’re not enforcing any launch type check when deploying to ECS.
When you trigger a pipeline, if you have Auto DevOps enabled and if you have correctly entered AWS credentials as environment variables, your application will be deployed to AWS ECS.
AUTO_DEVOPS_PLATFORM_TARGETvariable and a Kubernetes cluster tied to your project, only the deployment to Kubernetes will run.
ECSwill trigger jobs defined in the
Jobs/Deploy/ECS.gitlab-ci.ymltemplate. However, it’s not recommended to include it on its own. This template is designed to be used with Auto DevOps only. It may change unexpectedly causing your pipeline to fail if included on its own. Also, the job names within this template may also change. Do not override these jobs’ names in your own pipeline, as the override will stop working when the name changes.
