Provision GitLab Cloud Native Hybrid on AWS EKS (FREE SELF)

GitLab "Cloud Native Hybrid" is a hybrid of the cloud native technology Kubernetes (EKS) and EC2. While as much of the GitLab application as possible runs in Kubernetes or on AWS services (PaaS), the GitLab service Gitaly must still be run on EC2. Gitaly is a layer designed to overcome limitations of the Git binaries in a horizontally scaled architecture. You can read more here about why Gitaly was built and why the limitations of Git mean that it must currently run on instance compute in Git Characteristics That Make Horizontal Scaling Difficult.

Amazon provides a managed Kubernetes service offering known as Amazon Elastic Kubernetes Service (EKS).

*Cost calculations for actual implementations are a rough guideline with the following considerations:

  • Actual choices about instance types should be based on GPT testing of your configuration.
  • The first year of actual usage will reveal potential savings due to lower than expected usage, especially for ramping migrations where the full loading takes months, so be careful not to commit to savings plans too early or for too long.
  • The cost estimates assume full scale of the Kubernetes cluster nodes 24 x 7 x 365. Savings due to 'idling scale-in' are not considered because they are highly dependent on the usage patterns of the specific implementation.
  • Costs such as GitLab Runners, data egress and storage costs are not included as they are very dependent on the configuration of a specific implementation and on development behaviors (for example, frequency of committing or frequency of builds).
  • These estimates will change over time as GitLab tests and optimizes compute choices.

Available Infrastructure as Code for GitLab Cloud Native Hybrid

The GitLab Environment Toolkit (GET) is an effort made by GitLab to create a multi-cloud, multi-GitLab (Omnibus + Cloud Native Hybrid) toolkit to provision GitLab. GET is developed by GitLab developers and is open to community contributions. GET is where GitLab is investing its resources as the primary option for Infrastructure as Code, and is being actively used in production as a part of GitLab Dedicated.

Read the GitLab Environment Toolkit (GET) direction to learn more about the project and where it is going.

The AWS Quick Start for GitLab Cloud Native Hybrid on EKS is developed by AWS, GitLab, and the community that contributes to AWS Quick Starts, whether directly to the GitLab Quick Start or to the underlying Quick Start dependencies GitLab inherits (for example, EKS Quick Start).

GET is recommended for most deployments. The AWS Quick Start can be used if the IaC language of choice is CloudFormation, integration with AWS services like Control Tower is desired, or preference for a UI-driven configuration experience or when any aspect in the below table is an overriding concern.

NOTE: This automation is in Open Beta. GitLab is working with AWS on resolving the outstanding issues before it is fully released. You can subscribe to this issue to be notified of progress and release announcements: AWS Quick Start for GitLab Cloud Native Hybrid on EKS Status: Beta.

The Beta version deploys Aurora PostgreSQL, but the release version will deploy Amazon RDS PostgreSQL due to known issues with Aurora. All performance testing results will also be redone after this change has been made.

Two and Three Zone High Availability

While GitLab Reference Architectures generally encourage three zone redundancy, AWS Quick Starts and AWS Well Architected consider two zone redundancy as AWS Well Architected. Individual implementations should weigh the costs of two and three zone configurations against their own high availability requirements for a final configuration.

Gitaly Cluster uses a consistency voting system to implement strong consistency between synchronized nodes. Regardless of the number of availability zones implemented, there will always need to be a minimum of three Gitaly and three Praefect nodes in the cluster to avoid voting stalemates cause by an even number of nodes.

Streamlined Performance Testing of AWS Quick Start Prepared GitLab Instances

A set of performance testing instructions have been abbreviated for testing a GitLab instance prepared using the AWS Quick Start for GitLab Cloud Native Hybrid on EKS. They assume zero familiarity with GitLab Performance Tool. They can be accessed here: Performance Testing an Instance Prepared using AWS Quick Start for GitLab Cloud Native Hybrid on EKS.

AWS GovCloud Support for AWS Quick Start for GitLab CNH on EKS

The AWS Quick Start for GitLab Cloud Native Hybrid on EKS has been tested with GovCloud and works with the following restrictions and understandings.

  • GovCloud does not have public Route53 hosted zones, so you must set the following parameters:

    CloudFormation Quick Start form field CloudFormation Parameter Setting
    Create Route 53 hosted zone CreatedHostedZone No
    Request AWS Certificate Manager SSL certificate CreateSslCertificate No
  • The Quick Start creates public load balancer IPs, so that you can easily configure your local hosts file to get to the GUI for GitLab when deploying tests. However, you may need to manually alter this if public load balancers are not part of your provisioning plan. We are planning to make non-public load balancers a configuration option issue link: Short Term: Documentation and/or Automation for private GitLab instance with no internet Ingress

  • As of 2021-08-19, AWS GovCloud has Graviton instances for Amazon RDS PostgreSQL available, but does not for ElastiCache Redis.

  • It is challenging to get the Quick Start template to load in GovCloud from the Standard Quick Start URL, so the generic ones are provided here:

AWS PaaS qualified for all GitLab implementations

For both Omnibus GitLab or Cloud Native Hybrid implementations, the following GitLab Service roles can be performed by AWS Services (PaaS). Any PaaS solutions that require preconfigured sizing based on the scale of your instance will also be listed in the per-instance size Bill of Materials lists. Those PaaS that do not require specific sizing, are not repeated in the BOM lists (for example, AWS Certification Manager).

These services have been tested with GitLab.

Some services, such as log aggregation, outbound email are not specified by GitLab, but where provided are noted.

Other combinations of node type and quantity can be used to meet the Grand Total. Due to the CPU and memory requirements of pods, hosts that are overly small may have significant unused capacity.

NOTE: If EKS node autoscaling is employed, it is likely that your average loading will run lower than this, especially during non-working hours and weekends.
