In my previous blog, I described how to use Oracle Developer Cloud to build and push the Node.js microservice Docker image on DockerHub. This blog will help you understand, how to use Oracle Developer Cloud to deploy the Docker image pushed to DockerHub on Container Engine for Kubernetes. Container Engine for Kubernetes Container Engine for Kubernetes is a developer-friendly, container-native, enterprise-ready managed Kubernetes service for running highly available clusters...

  Oracle Integration Cloud (OIC) provides the ability to develop an integration in the cloud.  The integration can connect cloud and/or on-premise applications, however, these integrations are maintained directly in the cloud and not in any Source Code Management (SCM) system.  Deploying an integration from one OIC instance to another OIC instance is a manual process. It requires exporting an integration from one instance and importing that integration into the next instance. ...

Yeah, I’ve said it. You can write lean (not as lean as Go, but still!) microservices in Java EE. If you’re still scrolling down, let me tell you something — Java is an awesome language. It has had a rough patches giving new developers a warm welcome, unlike Python or JavaScript; it’s awesome nevertheless. Unless you’ve been living under a rock for the past 5 years, you might have heard one or more of the below buzzwords. 1. Reactive Computing 2. Microservices 3. Containerisation 4....

Oracle API CS offers an inbuilt feature to limit or remove the certain fields and headers which is the part of request and response payload. This policy is called Redaction policy. The policy can be used in both request and response pipeline. In the request pipeline, headers, queries and payload content can be controlled before the backend service is invoked. Similarly, in the response pipeline, headers, queries and payload content can be controlled before the response sent to...

You must have heard about the new kid on the block––Helidonfrom Oracle. It is an open source Java framework that enables one to write, among other things, lightweight microservices using functional and reactive programming paradigms. One can use Helidon’s simple yet powerful core reactive web server to quickly build cloud native microservices. And if you like writing applications using the 12 factor methodology, Helidon has you covered. Helidon’s config component provides...

Last night we presented our online training. Things went well until near the end where for some reason voice and video dropped for no apparent reason. Our coordinator Lindsay kept the recording going and soon as we reconnected I continued the session and went through the Q&A. So if you missed the end of the end of the training, please do check back with the recording. For those on the training will have seen at the start of the training links to my social media profile, so...

Fn is a cloud agnostic, container native, serverless platform and as such, Fn leverages Docker extensively. In a nutshell, Fn will expose any piece of code as a Serverless function by turning it into a Docker image. All the heavy lifting of making the Docker image, invoking it properly with the right input, etc. is handled by Fn. As an Fn user/function developer, you don’t need to understand Docker and all its underpinning as Fn abstracts Docker away. Leveraging Docker also...

After months of hard work and burning the midnight oil I am very proud to announce ApiaryUI - our brand new, fully rethought, and refactored version of our existing Interactive Documentation. We already gave ApiaryUI to our betatesters as a Christmas gift. We are now making it available for everyone, but before it will become THE API documentation, we want to hear from you. ApiaryUI is implemented in a way that allows complete separation from apiary.io and possibly forming a...

This post demonstrates how to develop an Fn function that is triggered by a GitHub webhook and posts new release details to Twitter. It covers the general concept, code as well as configuration and deployment of your function. Once configured and deployed, the serverless function will be invoked in response to a new release in a GitHub repository (thanks to the webhook) and post its details (name, version and URL) to Twitter. If everything works out well, you should have a...
