Trying GitHub Container Registry Using GitHub Actions

September 29, 2020 Geoff Hudik

Recently I decided to try GitHub Container Registry (GHCR) out as a possible alternative to Docker Hub and Azure Container Registry (ACR) for certain apps. While I knew it wouldn’t expose all the features of a registry like ACR, many times that’s not needed and it was compelling to have source, build (via Actions), and…

Docker pass Credential Helper on Ubuntu

September 15, 2020 Geoff Hudik

Recently having docker login credentials stored in plain text on a server was bugging me. Granted the credentials are base64 encoded but easily decoded at which point the container registry is vulnerable as well. I thought using one of the credential helpers would be quick and simple but I was mistaken. In my case I…

CI/CD with Pulumi, Docker, and TeamCity

May 6, 2020May 29, 2020 Geoff Hudik

After setting up Pulumi to build an Azure VM, I wanted to try incorporating it into a TeamCity CI/CD process. The Pulumi TeamCity doc details the installation steps such as installing Node.js. In my case however the target build agents are used by many different applications so I’m hesitant to install or mess with system…

Deploying .NET Apps to Raspberry Pi with GitHub Actions and Docker

April 27, 2020 Geoff Hudik

The last post in this series explored different ways of deploying .Net apps to a Raspberry Pi and touched on some of the pros and cons of using Docker for this. This post covers using GitHub actions to build a Raspberry Pi image and deploy to Docker Hub when commits are pushed to the repository.…

April 27, 2020 Geoff Hudik

Overview While I settled on Docker as the means to deploy and run my .NET code on a Pi for this project, it’s worth looking at other options. This post explores a few common options, each of which has its own pros and cons and may be useful at different times. It also touches on…

Automating Raspberry Pi Setup

April 27, 2020May 24, 2020 Geoff Hudik

After creating the SD card for this project, I next wanted to automate the initial Pi setup on the first login – further configuring system settings and installing applications. While it might have been possible to do some of that with pi-gen or Yocto layers, I just wanted a simple script to execute initially. In…

Scripting Raspberry Pi Image Builds

April 27, 2020May 24, 2020 Geoff Hudik

One of the first steps towards Raspberry Pi fun is installing a Raspberry Pi operating system image on an SD card and this project was no different. Initially it’s common to use a GUI tool like the recently announced Raspberry Pi Imager or Balena Etcher. You might think this is more a one-time setup step…

Raspberry Pi Cat Motion Siren

April 27, 2020May 23, 2020 Geoff Hudik

I’ve been wanting to dive deeper into Raspberry Pi development for a while but needed to make the time and find a project. Image classification using machine learning has been an interest so something using the motion sensor and camera sounded ideal. As it turns out, my significant other’s cat provided an opportunity to put…

Docker PowerShell Scripts for Local Development

May 27, 2019 Geoff Hudik

In working on a cloud native application locally, there have been various dependencies to spin up in order to run the different services. These include things like: Netflix Eureka for service discovery Spring Cloud Config for externalized, distributed configuration RabbitMQ for decoupled messaging and bulk processing Redis for distributed caching MySQL for data persistence Most…
