Running Containers at any real-world scale requires container orchestration, and scheduling platform like Docker Swarm, Apache Mesos, AWS ECS but the most popular out of it is Kubernetes. Kubernetes is an open source system for automating deployment and management of containerised applications.
In this post, We’ll share the process how you can Develop and Deploy Microservices based PHP Laravel Application on the Container Environment - Docker and Kubernetes and adopt DevOps in existing PHP Applications.
To follow this guide you need -
It is an open source platform that automates container operations, and Minikube is best for testing Kubernetes.
Kubectl is command line interface to manage Kubernetes cluster either remotely or locally. To configure kubectl on your machine follow this link.
Shared Persistent Storage is permanent storage that we can attach to the Kubernetes container so that we don`t lose our data even when container dies. We will be using GlusterFS as the persistent data store for Kubernetes container applications.
Scala Application Source Code is source code that we want to run inside a Kubernetes container.
Dockerfile contains a bunch of commands to build PHP Laravel application.
The Registry is an online image store for container images.
Below mentioned options are few most popular registries.
At the time of writing this blog, I haven`t got any official image of Scala sbt so I decided to build a base image for Scala sbt. In this image, we are using OpenJDK 8 as a development environment and Scala sbt 0.13.
The Below mentioned command will build your scala base container image.
As Scala sbt don't have any official image of Docker container so we will be using above created image of Scala sbt as a base image for Scala applications.
The below-mentioned command will build your application container image.
Now we publish our Scala application container image on Private Docker Registry.
Login to Container Registry
Retag Container Images
Push Application container Images
Reference Link for Pull and Push to Quay.io docker registry.
Similarly, we can push or pull any container image to any of below-mentioned container registry like Docker Hub, AWS ECR, Private Docker Registry, Google Container Registry etc.
Deploying application on kubernetes with ease using deployment and service files either in JSON or YAML format.
Following Content is for “<name of application>.deployment.yml” file of python container application.
Following Content is for “<name of application>.service.yml” file of python container application.
Scala Container Application can be deployed either by kubernetes Dashboard or Kubectl (Command line).
I`m explaining command line that you can use in production kubernetes cluster.
Now we have successfully deployed Scala Application on Kubernetes.
We can verify application deployment either by using Kubectl or Kubernetes Dashboard.
Below mentioned command will show you running pods of your application with status running/terminated/stop/created.
Result of above command
Get the External Node Port using the below mentioned command.External Node Port is in the range from 30000 to 65000.
Launch web Browser and open any of the below-mentioned URLs.
http://<kubernetes master ip address >: <application service port number>
http://<cluster ip address >: <application port number>
Check Status of Pods.
Check Logs of Pods/Containers.
Check Service Port Status.
Check requirements/dependencies of application.
