Deploying the NGINX Operator and accessing NGINX on OpenShift v4 can be done through the following steps. This process assumes you have administrative access to your OpenShift cluster and are familiar with basic OpenShift and Kubernetes concepts.
1. Log into your OpenShift Cluster:
– Use the OpenShift CLI (`oc`) or the OpenShift web console to log into your OpenShift v4 cluster.
2. Create a New Project:
– Create a new project (namespace) for your NGINX Operator deployment. In the CLI, use `oc new-project `.
3. Install the NGINX Operator:
– Through the Web Console:
– Navigate to the OperatorHub in the OpenShift web console.
– Search for the “NGINX Operator”.
– Click on the NGINX Operator and follow the prompts to install it. Make sure to select the project (namespace) you created.
– Using the CLI:
– If you prefer to use the CLI, you can apply YAML manifests to install the Operator. The YAML files can be obtained from the NGINX Operator’s documentation or its repository.
4. Verify the Operator Installation:
– Ensure that the NGINX Operator is running. You can check this through the web console in the “Installed Operators” section of your project, or by running `oc get pods` in your project namespace.
5. Deploy an Instance of NGINX:
– Create a custom resource (CR) for NGINX. This is typically done by applying a YAML file that defines the NGINX instance.
– The YAML file should specify the configuration for your NGINX instance. You can find examples in the NGINX Operator documentation.
– Apply the configuration with `oc apply -f `.
6. Expose NGINX Service:
– Once your NGINX instance is running, you need to expose it to access it externally.
– Create a route in OpenShift. This can be done either through the web console by navigating to your service and creating a route, or using the CLI with `oc expose svc/`.
7. Access Your NGINX Instance:
– After the route is created, you will get a URL to access your NGINX instance.
– Open a web browser and navigate to the URL provided by the route. You should see the default NGINX welcome page or your custom application if you configured one.
8. Monitor and Maintain Your NGINX Instance:
– Use OpenShift’s monitoring and logging tools to keep track of your NGINX instance’s performance and health.
– Update your NGINX configuration or the Operator itself as needed.
9. Ensure Security and Compliance:
– Follow best practices for securing your NGINX deployment, including setting up TLS for encrypted traffic, if necessary.
Remember, the specifics might vary depending on the version of the NGINX Operator and OpenShift. Always refer to the latest official documentation for detailed instructions and best practices.
