In other cases we can leverage a configuration management system and do the orchestration ourselves. However, there are still some cases where either of these solutions are impractical or just too complex for the immediate problem… and you don’t have a Consul cluster at hand either :(.… [Keep reading] “Making application configuration files dynamic with confd and Azure Redis”
Confd is a Golang written binary that can help us make configuration files dynamic. It achieves this by providing a templating engine that is driven by backend data stores like etcd, consul, dynamodb, redis, vault, zookeeper.
A few days ago I started putting together a BYO load-balancing PoC where I wanted to use confd and Nginx. I realised however that some features that I needed from confd were not yet released. Not a problem; I was able to compile the master branch and package the resulting binary into an Nginx container all in one go, and without even having Golang installed on my machine.… [Keep reading] “Build from source and package into a minimal image with the new Docker Multi-Stage Build feature”
And so a personal project was born. To create a simple JS API and get it running in the cloud.… [Keep reading] “Creating a simple nodejs API on AWS (including nginx)”
