Kubernetes calls for automatic management and deployment of containerised applications to Laravel.

The Laravel frameworks well for the development of the PHP applications where a person can develop Minimum Viable Product (MVP), to make a prototype of any new idea or work on the well-knit enterprise system. The Laravel framework facilitates the workflows and the developmental tasks.

Now, the main issue is the deployment of the applications. For several web services, the developers need to satisfy many requirements. Moreover, it is mandatory to have the mechanism so that the developer can operate the application seamlessly online. It is also necessary to balance the server load in an efficient manner. Let us see how to run the simple Laravel Application by using the local set up of the Kubernetes.

What is Kubernetes and Why is it required?

This portable and extensible open-source platform helps in managing the containerized services and the workloads. It helps in facilitating the declarative automation and the configuration. The Kubernetes tools, support, and services are available extensively that makes it a fastest-growing and a large ecosystem.

Kubernetes comes packed with a number of features, as it is a micro services platform, container, and the portable cloud platform. It is a ‘container-centric’ management environment used by the Laravel development Company. It applies networking, computing and the storage infrastructure in lieu of the user workloads. The simplicity is provided through PaaS or Platform as a Service and flexibility is extended by the Infrastructure as a Service (IaaS) that enables the portability across the providers of the Kubernetes infrastructure.

Deployment of the Laravel Based-Application to the Kubernetes

The Companies can hire Laravel developer from the best Laravel development Company that renders support on the stateless and straightforward deployment of the Kubernetes local set-up. The detailed steps will help in the quick application of the Kubernetes. Moreover, the developers can run it on kinds of cloud such as Amazon Web Services (AWS) or the Google Cloud Engine. The Kubernetes can also run the applications on the Minikube tool. It simplifies the setup.

Here, Minikube is a kind of virtual machine together with Docker and the Kubernetes platform. The Laravel developer needs to deploy the application instantly on the scale that leads the application to only ‘three instances’, which use the Kubernetes and a ‘Docker Container’.

Ways of Deployment of Laravel to Kubernetes

The deployment of the Laravel application to the Kubernetes can be a tedious process so it is advisable to hire Laravel developer that can help in a seamless deployment process by using a number of ways:

  • Building the Image of the PHP Laravel Application

The developer can design the clone of the application or frame a fresh Laravel application. The clone can be used in the project directory as below:

cd / to / your / work / directory
  • Running of the Docker Image

The building and running of the Docker image in the repository that has all the related files and Laravel code can be done by building the following command:

| docker-compose build

In this, the developer after doing the cloning of the repository can enter the root directory and run following command in their terminal. For this command to run the developer must install the Docker. Now, the next step is the starting of the project with the Docker image that has just been created. This command will be used to start the Docker image:

docker-compose up-d

While deploying the Laravel to Kubernetes, the local host will use the port 8181. Therefore, it is necessary to make sure that no other Laravel application uses it.

  • Pushing the Build Image to the Docker Hub

Now, the Laravel developer can create the new image that will be pushed to the Docker Hub. Here, the Docker Hub is the commercial repository that hosts the Docker images from varied projects. The building of the image and pushing of the image to the Docker Hub allows the developer to ‘pull in the image’ and makes deployment to Kubernetes on a later stage.

One thing worth noting here is that other developers can make use of this image as a base and then extend it with their code. The developers should make sure that they are logged into the Docker Hub before pushing the Docker images.

  • Tagging and Labeling of the Image

The developer must label and tag the image before pushing it to the repository of the Docker Hub. Here the user can save the Docker Image by any name they find suitable. After this step, it is necessary to upload the Docker image by using the command given below:

docker push docker.io/chosen name/tag name chosen by the user

Now, visit the hub.docker.com and verify that the image has been uploaded so that it can help in the deployment with the Kubernetes.

Deploying of the Image and Other Applicability in Kubernetes

  1. Deploying of Docker Image in Kubernetes

After building the image in the above steps, now the developers can move ahead with the deployment process. It is necessary to see that the Kubernetes is used in the right context. If the Companies face any problem in all these steps. It can be seen that the local hosting service used here is Minikube where the developer needs to deploy the Docker image.

It can be run by using the following command in the Kubernetes set up:

kubect1 run laravel-kubernetes-demo –image=yourname /Laravel-kubernetes-demo –port=8181 –image-pull-policy=IfNotPresent

In the above-given command, it can be seen that the ‘kubect1’ will seamlessly run ‘demo application’ on the provided Docker image. It makes the port 8181 accessible for the listening purpose.

In this, last given parameter used in this above command simply tells the ‘kubect1’ not to ‘pull the image’ from the registry that is the Docker Hub that exists locally and in this condition, this is a local host only. The developers must note here that they are required to log in to the Docker Hub so that the ‘kubect1’ can check for the updated image.

The user can make use of GUI Dashboard of the Minikube in order to observe the cluster. This GUI will also help in visualising mostly the Docker-related concepts.

  1. Exposing the Service in the Kubernetes Setup

The developers have created the deployment that runs the Laravel application container in the Kubernetes local setup. Here are few pointers involved as under:

  • The Pod operating in this cluster has the dynamic IP address. If the user directly route traffic to the Pod using the particular IP, still they are required to update provided ‘routing table’ every time it restarts the Pod.

  • Here, a fresh IP address is always assigned to it on the container restart or the deployment. In order to avoid the management of the IP address manually, the developers must use the exposed service in the Kubernetes.

  • The ‘service’ used here acts as the ‘load balancer’ for the set of the Pods used in this set-up.

  • In any situation, if Pod’s IP address alters, then the ‘Services’ will always keep a point of it. The ‘Service’ here will have the similar IP address so the developers need not to update anything in a manual manner.

For showing the list of running the services in the Kubernetes Setup after being deployed from the Laravel, the developers can run this command:

kubect1 get services

The users can also see the running of the services under the navigation menu of the “Services” provided in the Dashboard. To verify the exposure of the Services and deployment of the Laravel to Kubernetes further, it is advised to run the application in the browser.

  1. Scaling of the Deployed Applications

After the successful deployment of the application, the developers can run the deployment with the single pod that was running in the ‘Services’. This pod has a provision of the node and exposed to the single web service. The developers can scale the Kubernetes deployment on the three scales that is similar to running the deployment on the three pods. The Kubernetes also gives a provision to scale the multiple pod’s service.

The companies who are looking forward to deploying the Laravel application to the Kubernetes setup can hire Laravel developer from the popularLaravel development Company. They will not only help your team in the successful deployment of Laravel but also extend the support for the other micro services.

It is necessary to do the proper balancing of the load and the configuration of the database. For debugging purpose, the developers can use the commands to see if the setup is working in accordance or not. The deployment to the Kubernetes set up will help the companies to use the application along with the Google cloud-based services and for the usage in the real-life applications. The local Kubernetes set up will also help in balancing the server loads in a great way.
