# Prepare Auto DevOps for deployment **(FREE)**
|
|
|
|
If you enable Auto DevOps without setting the base domain and deployment
|
|
strategy, GitLab can't deploy your application directly. Therefore, we
|
|
recommend that you prepare them before enabling Auto DevOps.
|
|
|
|
## Deployment strategy
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/38542) in GitLab 11.0.
|
|
|
|
When using Auto DevOps to deploy your applications, choose the
|
|
[continuous deployment strategy](../../ci/introduction/index.md)
|
|
that works best for your needs:
|
|
|
|
| Deployment strategy | Setup | Methodology |
|
|
|--|--|--|
|
|
| **Continuous deployment to production** | Enables [Auto Deploy](stages.md#auto-deploy) with the default branch continuously deployed to production. | Continuous deployment to production.|
|
|
| **Continuous deployment to production using timed incremental rollout** | Sets the [`INCREMENTAL_ROLLOUT_MODE`](customize.md#timed-incremental-rollout-to-production) variable to `timed`. | Continuously deploy to production with a 5 minutes delay between rollouts. |
|
|
| **Automatic deployment to staging, manual deployment to production** | Sets [`STAGING_ENABLED`](customize.md#deploy-policy-for-staging-and-production-environments) to `1` and [`INCREMENTAL_ROLLOUT_MODE`](customize.md#incremental-rollout-to-production) to `manual`. | The default branch is continuously deployed to staging and continuously delivered to production. |
|
|
|
|
You can choose the deployment method when enabling Auto DevOps or later:
|
|
|
|
1. In GitLab, go to your project's **Settings > CI/CD > Auto DevOps**.
|
|
1. Choose the deployment strategy.
|
|
1. Select **Save changes**.
|
|
|
|
NOTE:
|
|
Use the [blue-green deployment](../../ci/environments/incremental_rollouts.md#blue-green-deployment) technique
|
|
to minimize downtime and risk.
|
|
|
|
## Auto DevOps base domain
|
|
|
|
The Auto DevOps base domain is required to use
|
|
[Auto Review Apps](stages.md#auto-review-apps), [Auto Deploy](stages.md#auto-deploy), and
|
|
[Auto Monitoring](stages.md#auto-monitoring).
|
|
|
|
To define the base domain, either:
|
|
|
|
- In the project, group, or instance level: go to your cluster settings and add it there.
|
|
- In the project or group level: add it as an environment variable: `KUBE_INGRESS_BASE_DOMAIN`.
|
|
- In the instance level: go to **Main menu > Admin > Settings > CI/CD > Continuous Integration and Delivery** and add it there.
|
|
|
|
The base domain variable `KUBE_INGRESS_BASE_DOMAIN` follows the same order of precedence
|
|
as other environment [variables](../../ci/variables/index.md#cicd-variable-precedence).
|
|
|
|
If you don't specify the base domain in your projects and groups, Auto DevOps uses the instance-wide **Auto DevOps domain**.
|
|
|
|
Auto DevOps requires a wildcard DNS `A` record matching the base domains. For
|
|
a base domain of `example.com`, you'd need a DNS entry like:
|
|
|
|
```plaintext
|
|
*.example.com 3600 A 1.2.3.4
|
|
```
|
|
|
|
In this case, the deployed applications are served from `example.com`, and `1.2.3.4`
|
|
is the IP address of your load balancer, generally NGINX ([see requirements](requirements.md)).
|
|
Setting up the DNS record is beyond the scope of this document; check with your
|
|
DNS provider for information.
|
|
|
|
Alternatively, you can use free public services like [nip.io](https://nip.io)
|
|
which provide automatic wildcard DNS without any configuration. For [nip.io](https://nip.io),
|
|
set the Auto DevOps base domain to `1.2.3.4.nip.io`.
|
|
|
|
After completing setup, all requests hit the load balancer, which routes requests
|
|
to the Kubernetes pods running your application.
