Deploy the relay proxy

Deploy in Kubernetes using Helm

The relay proxy can be deployed in Kubernetes using a helm chart.
Helm is an invaluable tool for configuring and deploying applications to a Kubernetes environment.

Below are the steps for installing a Helm Chart from a GO Feature Flag Helm repository.

Prerequisites

• Access to a Kubernetes cluster
• Helm CLI installed on the client machine

Step 1: Prepare and Configure the Repository

Add the repository to Helm with the Helm repository add command and provide a name and the repository URL. For example:

helm repo add go-feature-flag https://charts.gofeatureflag.org/

Step 2: Install the Chart

Install the Helm Chart with the Helm install command and provide the custom repository name, the chart name and any necessary values files.
You can look at the helm doc to know exactly what you can change in the values.yaml file.

helm install go-feature-flag/relay-proxy -f values.yaml

Step 3: Verify The Chart Installation

Verify the Helm Chart installation with the Helm list command. For example:

helm list

Deploy as AWS Lambda

The GO Feature Flag relay proxy can easily be launched as an AWS Lambda function. To do this, simply set the startAsAwsLambda option in your configuration file to true, like so:

# ...
startAsAwsLambda: true

Once you've updated your configuration file, you can deploy your function in AWS and configure it to be accessible via HTTP. This can be achieved by creating an API Gateway or an Application Load Balancer (ALB) and linking it to your Lambda function.

By configuring your GO Feature Flag relay proxy to run as an AWS Lambda function, you can take advantage of many benefits of serverless computing, including automatic scaling, reduced infrastructure costs, and simplified deployment and management.
