For details, see [known issues and limitations](https://gitlab.com/charts/gitlab/blob/master/doc/architecture/beta.md#known-issues-and-limitations) in the charts repository.
-[No in-cluster HA database](https://gitlab.com/charts/gitlab/issues/48)
- MySQL will not be supported, as support is [deprecated within GitLab](https://docs.gitlab.com/omnibus/settings/database.html#using-a-mysql-database-management-server-enterprise-edition-only)
In order to deploy GitLab on Kubernetes, a few prerequisites are required.
## Installing GitLab using the Helm Chart
The `gitlab` chart includes all required dependencies, and takes a few minutes
to deploy.
TIP: **Tip:**
For large scale deployments, we strongly recommend using the

## Configuring and Installing GitLab
### Deployment of GitLab to Kubernetes
> **Note**: For deployments to Amazon EKS, there are [additional configuration requirements](preparation/eks.md).
To deploy GitLab, the following three parameters are required:
For simple deployments, running all services within Kubernetes, only three parameters are required:
-`global.hosts.domain`: the [base domain](preparation/networking.md) of the
-`global.hosts.domain`: the [base domain](preparation/networking.md) of the wildcard host entry. For example, `mycompany.io` if the wild card entry is `*.mycompany.io`.

-`certmanager-issuer.email`: Email address to use when requesting new SSL certificates from Let's Encrypt.
-`global.hosts.externalIP`: the [external IP](preparation/networking.md) which
the wildcard DNS resolves to.
-`certmanager-issuer.email`: the email address to use when requesting new SSL

For enterprise deployments, or to utilize advanced settings, please use the instructions in the [`gitlab` chart project](https://gitlab.com/charts/gitlab) for the most up to date directions.
NOTE: **Note:**
-[External Postgres, Redis, and other dependencies](https://gitlab.com/charts/gitlab/tree/master/doc/advanced)
For additional configuration options, consult the [full list of settings](https://gitlab.com/charts/gitlab/blob/master/doc/installation/command-line-options.md).
Once you have all of your configuration options collected, you can get any
dependencies and run helm. In this example, the helm release is named "gitlab":

### Networking Prerequisites
### Networking requirements
This chart configures a GitLab server and Kubernetes cluster which can support dynamic [Review Apps](https://docs.gitlab.com/ee/ci/review_apps/index.html), as well as services like the integrated [Container Registry](https://docs.gitlab.com/ee/user/project/container_registry.html) and [Mattermost](https://docs.gitlab.com/omnibus/gitlab-mattermost/).

and [Mattermost](https://docs.gitlab.com/omnibus/gitlab-mattermost/).
To support the GitLab services and dynamic environments, a wildcard DNS entry is required which resolves to the [Load Balancer](#load-balancer-ip) or [External IP](#external-ip). Configuration of the DNS entry will depend upon the DNS service being used.

#### External IP (Recommended)
#### External IP (recommended)
To provision an external IP on GCP and Azure, simply request a new address from the Networking section. Ensure that the region matches the region your container cluster is created in. Note, it is important that the IP is not assigned at this point in time. It will be automatically assigned once the Helm chart is installed, and assigned to the Load Balancer.

This should only be used when Tiller cannot be normally deployed.
