One day, I was interested to find out how the process of adding a forwarding number works and if it might be possible to mess with it. Luckily for me, I did find such a way.

Building off our AlarmManager, we want the ability to have the alarm appear, even if the device is locked. Here’s how.

There aren’t a lot of good write-ups on how to use the AlarmManager, so here is an example that launches an Activity using the AlarmManager.

I've been recently spending quite a bit of time in the DevOps space and working to build out better CI/CD pipelines, mostly utilizing Docker. In this post, I demonstrate building out a pipeline that will create a simple Docker image and push it to Amazon's EC2 Container Registry.

In Java, interfaces are used all over the place. Occasionally, these will need to be marshalled into XML/JSON. However, JAX-RS creates its own JAXBContext on its own. So, you may see exceptions like this…

Foo is an interface, and JAXB can't handle interfaces.

We’ve recently been in the transition from using Spring in a Tomcat environment to Java EE7 in Wildfly? (still finalizing the container of choice).

Since we’re in transition, we’d like to run the application in both Tomcat and Wildfly, without having to make changes to the bundled application. It should just work on deploy. Here’s how to do it…

There are many different ideas and approaches for doing QA testing, many of which depend on what project management style you’re using, the developers on the team, and if you have a QA/functional testing team. However, this is how I’ve found it to be successful, based on my observations working on the CREST team at Virginia Tech.

An overview of reverse proxies and Traefik, presented at the Northern Virginia Linux Users Group.

Several folks asked about my recording setup for my DockerCon 2020 talk. So, here's my hardware, as well as some tips I learned along the way!

At DockerCon's first virtual conference, I had the opportunity to speak about Docker Compose! Here are my slides and extra resources. Enjoy!

Running Traefik in a Swarm cluster on non-managers can be tricky. There are quick and easy ways, but there are more secure ways. In this post, we'll talk about using a Docker Socket proxy to better protect us.

Docker Contexts make it easy to manage remote Docker machines. Here's how to use SSH to connect to your remote machines.

Feeling overwhelmed while getting started with containers? Have you been tasked to figure out how to train everyone back at your organization? There's just so much to learn and teach! In this talk, we’ll start with a tiny bit of history to motivate the "why" and quickly move into the "what" by explaining what container and images actually are (they're not just magical black boxes!). We'll talk about how volumes help with data persistence and include an overview of Docker Compose and even orchestration. There will be plenty of live demos and fun!

How can you build an elastic QA environment that can support many concurrent stacks, be quickly available, yet minimize costs? I'll tell you how we did it!

In my last post, I talked about how we're using Docker App in development. In this post, I dive into how we keep it up-to-date when using several upstream component repos.

My dev team has been using Docker App for 8 months and it has changed everything. Here's what our environment looks like now.

I recently wanted to test a multi-container ECS task definition locally, which means using a single network namespace. But, how? And what does it buy me?

Developing applications is tough. Especially in the ever-changing environments. We have local development. QA validation. Pre-prod/staging. Production. But, how do we ensure our applications work the same everywhere? While containers help out, they aren't the only thing to keep in mind. The folks at Heroku, in 2011, published "The Twelve-Factor App", which has become the standard for building cloud-native applications.

Here's a quick tip on how to join an ECS cluster at startup using EC2 tags

DockerCon EU 2018 has come and gone! It was a blast and here are my key takeaways!

Docker App is an experimental tool that makes it easy to share multi-service applications. Create a Compose file, package it in an image, and voilà! You now have an "app-in-a-box"! Not convinced yet? No worries! It took a while for me to be convinced too! In this session, we'll start off by diving into how Docker App actually works, which will help us understand the use cases. We'll see how dev environments can hook in to this app-in-a-box by replacing the service being worked on with a dev container. Then we'll move on to see how end-to-end functional tests are much easier to run. And, finally, we'll see how to maintain an "app-in-a-box" with the latest versions of each component in a CI/CD pipeline, allowing for a unique app-in-a-box for each feature branch under development. Lots of good material! And lots of live demos!

Being new to containers can feel like sitting in front of a firehose and trying to drink all of the water coming at you. Especially here at DockerCon! If you feel that way, no worries! This workshop is for you! In this workshop, we're going to dive into what containers and images actually are and some best practices around them, how to use volumes and port mappings, and how to run multi-service applications. There will be quite a few hands-on opportunities, as well as training from some of our Docker Captains. You won't want to miss this! Please note that this workshop will not talk about orchestration or running containers in production (monitoring, logging, etc.), as there are other workshops solely focused on these topics.

Quick pro-tip - use socat to "sniff" the Docker client/server traffic

If you're using Traefik in Swarm mode, it needs to listen to Docker events. Here's how to do it without having all of your traffic go through manager nodes.

Using multi-stage builds with the target flag, we can use a single Dockerfile for dev and prod

Docker is for microservices, right? Sure, but it's not JUST for them. In this talk, I talk about why your dino apps need love and the benefits you can gain by giving them love.

Docker is often portrayed as a hypervisor, but it's not. Here's a quick reminder...

Docker has recently merged in support to perform "multi-stage builds." In other words, it allows you to orchestrate a pipeline of builds within a single Dockerfile. Here's a quick rundown...

At the time of this blog post, AWS ELBs don't support WebSocket proxying when using the HTTP(s) protocol listeners. There are a few blog posts on how to work around it, but it takes some work and configuration. Using Docker, these complexities can be minimized.

In this post, we'll start at the very beginning. We'll spin up an ELB, configure its listeners, and then deploy an application to an EC2 instance.

In case you missed it, DockerCon 2016 was amazing! There were several great features announced, with most of it stemming from orchestration is now built-in. You get automatic load balancing (the routing mesh is crazy cool!), easy roll-outs (with healthcheck support), and government-level security by default (which is crazy hard to do by yourself).

In case you're a little confused on how to spin up a mini-cluster, this post will show you how. It's pretty easy to do!

While attempting to build a multi-tenant Kubernetes platform, I decided to use Karpenter to help create node pools for each tenant. Here's how we made each pool and forced tenants into the pool.

At Virginia Tech, I've been leading an effort to build a multi-tenant platform, currently on top of Kubernetes. But, there are a lot of things needed to pull this off. We'll dive into some of those in this post.

Compose has slowly been adding support for additional backends, including an experimental k8s backend. I've been doing some digging to figure out how to support GitOps workflows, yet hook into the Docker Compose tooling.

It's often tempting to use process.env in your frontend code. But, that means you either have to run Node in all environments or need to build the app for each location. How can we build once, deploy anywhere? In this post, we'll talk about externalizing our configuration.
