This script is developed to be a tool while developing on a kubernetes cluster.
Certain program languages, like PHP, do not require you to always rebuild the container image.
With this script you can keep an watch job on your development directories and have changes uploaded to your containers automaticly on filesave.
This will enable you to rapidly develop a new application without the need to have to wait for image builds.
The container you are syncing to does need to have write rights in the selected locations, you also need to be logged in into the kubernetes cluster.
This script requires you to have the following programs installed and in your path:
- kubectl - kubernetes client (https://kubernetes.io/docs/tasks/tools/install-kubectl/)
- yq - tool to read and manipulate yaml files (https://github.com/mikefarah/yq#install)
Recommended way to use is to make a pod-dev-syncer.yaml in the root of your project and run
/path/to/pod-dev-syncer -C /path/to/project/pod-dev-syncer.yaml
You can use the commandline options, but that is fully at own risk.
