In this post, I am following up on the post series about Running Eclipse MicroProfile applications in Oracle Cloud by showing how to do it in Microsoft Azure Web Apps for Containers. I am using the same simple application called CloudEE Duke as in the previous posts. The only difference is that I now package the applications as Docker Images. ...

An essential step of any CI/CD pipeline is deployment. If the pipeline operates with Docker containers and deploys to K8s clusters then the goal of the deployment step is to deploy a specific Docker image (stored on some container registry) to a specific K8s cluster.  Let’s say there is a VM where this deployment step is being performed. There are a ...

If you use Docker, you should know that it has a client-server architecture. There is the docker command line tool, which sends all the commands (build, pull, run etc) to the Docker Host’s API; the command line tool is just an elegant wrapper so you don’t have to make raw HTTP calls yourself. This architecture gives a very convenient decoupling. ...

In one of my previous posts I showed how to run an ADF essentials application on Tomcat in a docker container. I am using this approach primarily for sample applications as a convenient way to share a proof-of-concept. In this post I am going to describe how to enrich the docker container with Oracle DB so my samples can be ...

During the recent months I’ve been helping a company improving their automated testing practices. Besides doing coaching on TDD I also had the chance to work on a project consisting of multiple services where I was able to introduce some service tests using Docker. It’s the first time I’ve used Docker on a project for real and I was quite ...

In one of my previous posts I described how to create a Docker container serving as a builder machine for ADF applications. Here I am going to show how to use this container as a function on Fn platform. First of all let’s update the container so that it meets requirements of a function, meaning that it can be invoked as a ...
