Managing Docker Containers with OpenShift and Kubernetes

For the last few years, Docker containers have been all the rage in the DevOps world. After all, whatโ€™s not to like? They allow you to strip out 99% of stuff in your VM and just deploy your code.

Containers can save resources, speed deployment, scale well and offer more fault tolerance. But how do you manage them?

In my experience, the Docker Machine and Docker Swarm stack hasnโ€™t lived up my to expectations. It has a limited API, no support for monitoring and logging, and much more manual scaling. AWSโ€™s EC2 containers scale well, but youโ€™ll be locked into Amazon.

In my opinion, the best current stack for Docker containers includes Kubernetes and OpenShift. In this blog I will give a brief introduction to Kubernetes + OpenShift with an eye for what they do well…

Could the Equifax Hack Have Been Prevented by a Microservices Architecture?

When I heard that the Struts Open Source framework played a role in the recent Equifax hack, I wanted to do some research to understand how it happened. Struts is a commonly-used Java framework that I have applied in the past. And Iโ€™m not alone in that: it is reported that in 65% of Fortune 500 companies currently implement Struts in some way.

So, I did a little digging and performed a thought experiment asking myself the following question: โ€œIf Equifax had a pure-play Microservices Architecture in place, would it have solved the problem?โ€

Using Docker + AWS to Build, Deploy and Scale your App

Brandon Klimek Articles, AWS, Cloud, DevOps, Docker, Python, Spring, Spring Boot, Tutorial 8 Comments

I recently worked to develop a software platform that relied on Spring Boot and Docker to prop up an API. Being the only developer on the project, I needed to find a way to quickly and efficiently deploy new releases. However, I found many solutions overwhelming to set up.

That was until I discovered AWS has tools that allow any developer to quickly build and deploy their application.

In this 30 minute tutorial, you will discover how to utilize the following technologies:
– AWS CodeCommit – source control (git)
– AWS Code Build – source code compiler, rest runner
– AWS Codepipeline – builds, tests, and deploys code every time the repo changes
-AWS Elastic Beanstalk – service to manage EC2 instances handling deployments, provisioning, load balancing, and health monitoring
-Docker + Spring Boot – Our containerized Spring Boot application for the demo

Once finished, you will have a Docker application running that automatically builds your software on commit, and deploys it to the Elastic beanstalk sitting behind a load balancer for scalability. This continuous integration pipeline will allow you to worry less about your deployments and get back to focusing on feature development within your application.

React NowPlaying Educational Application

We at Keyhole have been helping our clients adopt JavaScript-based single-page applications for over five years. We have been impressed with the adoption and advancement of the ever-changing JavaScript ecosystem.

React is a JavaScript technology that our teams enjoy working with. However, React differs from the other frameworks weโ€™ve worked with in a handful of ways.

The best way to learn a new technology is to actually do something with it, as opposed to simply reading about it. So, we created a tangible React learning application to help our team get up-to-speed.ย The application repository has now been released publicly to help others learn.
