Fix "Cannot connect to the Docker daemon. Is the docker daemon running?" error

I spent a good couple of hours trying to fix this error message. I have the latest version of Docker installed on my Mac M1 Max running Sonoma 14.3.1. Every time I run a command that had to connect to the deamon, I was getting the same exact error: docker: Cannot connect to the Docker daemon at unix://Users/<user>/.docker/run/docker.sock. Is the docker daemon running?. See 'docker run --help'.This was not fun. But after a bit of googling (yes, ChatGPT etc couldn't help), I stumbled across the solution on this StackOverflow …[read more]

Deploying a Ghost blog to AWS Lightsail

It was about time to try a new hosting option for my blog. For the past few years I was running my blog on Azure WebApps Container service. It was OK but the setup was pretty complex and once it was deployed I totally forgot how to replicate the setup - maybe I should have blogged about it. Since I moved to AWS I've been looking into the various services and Lightsail seemed very promising for my needs. Lightsail is a lightweight, low cost (pun intended) but truly capable service for hosting web apps. It comes with a number of …[read more]

Random notes of a new Triathlete

What craziness could have possibly possessed me to start training for a triathlon at the age of 43? If you know me then you know that I’ve been a fitness fanatic for many years. While younger I preferred to play team sports (football (soccer), basketball etc) as I grew older I started focusing more on weight training and doing things on my own. I like the freedom and control of what, when and where. I’m a master of my own fate, with all the flaws and issues that come with it. Over the past few years, I built …[read more]
