Use environment variables to make a containerized Vue.js frontend application more flexible and deploy it to Code Engine

Leave a comment

This blog post addresses the topic, how to use environment variables to make a containerized Vue.js frontend application more flexible. We will touch following technologies Vue.js, NGINX, JavaScript, Dockerfile and Code Engine.

When you run a containerized application on a container orchestration platform like Kubernetes, Open Shift or on a serverless frameworks like Knative or Code Engine or other platforms, it’s helpful to pass endpoints to other applications to the containerized application by using environment variables. When the container will be restarted, these variables can be provided to the container and no adjustment in the source code is necessary. You can use configmaps or in Code Engine simply the environment variable itself.

The example source code you find in this workshop.

In addition, it’s useful when you take a look into this awesome blog post: Externalise and Configure Frontend Environment Variables on Kubernetes which was used for the starting point for the configuration.

This blog post addresses the topic, how to use environment variables to make a containized Quarkus application more flexible. We will touch following technologies Quarkus, OpenJ9 Java runtime, MicroProfile, Dockerfile definition and Code Engine.

When you run a containerized application on a container orchestration platform like Kubernetes, Open Shift or with a serverless framework like Knative or Code Engine or on other platforms, it is helpful to pass endpoints to other applications to the containerized application by using environment variables. When the container will be restarted, these variables can be provided to the container and no adjustment in the source code is necessary. You can use configmaps or in Code Engine simple the environment variable itself.

We will follow along an application example for the implementation and the example source code you find in the Get started to deploy a Java Microservices application to Code Engine workshop. (or the direct link to the used file in the GitHub repository is provided in the blog post itself)

New hands-on workshop: Get started to deploy a Java Microservices application to Code Engine

2 Comments

Code Engine is build to create modern, source-centric, containerized, and serverless apps and jobs.
Take a quiz to get started with the Code Engine terminology.

The topic batch jobs is more related to AI and machine learning, and run AI model training temporarily with highly workload, and thats at the moment not so much in my scope.

My starting point with Code Engine was in my YouTube video: Code Engine, Containerized Application, Node-RED Starter Kit and Scale To Zero. With that in mind, from my perspective Code Engine is a very good starting point for smaller containerized applications, because you can precisely control costs with scale to zero. … and by the way, it’s easy of use.

That motivated me to create a simple hands-on workshop, where you are guided to deploy the Cloud Native Starter security example application to Code Engine. The source code of the example application is included to the GitHub project of the workshop.
