Install nginx Ingress Controller
When you install the nginx Ingress Controller, our system automatically creates a Load Balancer. This Load Balancer acts as an entry point for incoming traffic. When traffic arrives, the Load Balancer forwards it to the Ingress Controller. The Ingress Controller is responsible for routing the traffic to the appropriate services within your Managed Kubernetes cluster based on the rules defined in the Ingress manifests.
Step 1. Install Helm
Using Helm package manager simplifies the process of deploying, managing, and scaling applications on Kubernetes.
The following sections contain instructions for installing Helm on Windows, Ubuntu, and macOS. For more installation options, check out the official installing Helm guide.
On Linux
1. In the Terminal, run the official Helm installation script:
curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bashThis command will download and install the latest version of Helm and place the Helm binary in /usr/local/bin/helm (or another location based on your system's configuration).
2. Verify that Helm was installed successfully by checking its version: helm version. You should get the installed version of Helm.
On macOS
If you have Homebrew installed, run brew install helm.
Verify installation by running helm version.This command should return the Helm version that was installed.
If you don’t have Brew on your macOS, follow the installation steps for Linux.
On Windows
Download the latest Helm release from the Helm GitHub releases page and extract the contents of the downloaded ZIP file to a directory of your choice. For instance, C:\Program Files\Helm.
Add Helm binary to the PATH:
1. Open the Start menu and search for Environment Variables.
2. Click Edit the system environment variables.
3. In the System properties window, click Environment variables.
4. In the System variables section, click New.
5. Provide a variable name and add the full path to the directory where you moved helm.exe (e.g., C:\Program Files\Helm).
6. Click OK to save the changes.
7. Verify the installation. In the Terminal, run helm version. You should get the latest release version downloaded from the GitHub repository in step 1.
Step 2. Create a namespace
Run the following kubectl command to create a namespace:
kubectl create namespace ingress-nginxStep 3. Add helm repository for the nginx Controller
Run the following command to add the helm repository for the nginx Ingress Controller:
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginxStep 4. Update helm repository
Update data in the helm repository:
helm repo updateStep 5. Install nginx Ingress Controller
Run the following command:
helm install ingress-nginx ingress-nginx/ingress-nginx \
--namespace ingress-nginx \
--set controller.ingressClassResource.name=nginxAfter the nginx Ingress Controller is installed, it will automatically create a Load Balancer on your behalf.
Step 6. Get an IP of a Load Balancer
To get the IP address of the created Load Balancer, execute the command below:
watch kubectl -n ingress-nginx get svcWait until the <pending> state of the EXTERNAL-IP column changes to the IP address.
The Load Balancer will be shown in the Gcore Customer Portal on the Load Balancers page. The traffic will reach the nginx Ingress Controller via this balancer.
