Kubernetes-envvar
Small cli application to read environment variables from Kubernetes' deployment.yaml, export them and run a command in the "new" environment
This is a WORK IN PROGRESS!!!
Motivation
I've been using Kubernetes for a while now and using environment variables to configure my applications and each environment (staging, production, etc) has got its own deployment.yaml and when the number of environment variables grows past two it gets annoying to run an application locally pointing to a different environment (e.g. staging).
So I decided to write this wee tool to do the "monkey job" of reading the deployment.yaml and exporting the environment variables
Usage
$ ./kubernetes-envvar <type: d|t> <filepath> <command and args>
Arguments:
- Type: It's either
torddepending on the structure of the yaml file.dis for the simpler yaml (see example/deployment.yaml)tis for a helm yaml file (see example/deploymentWithTemplate.yaml)
- Filepath: Is the path to the Kubernetes' deployment.yaml
- Command: Is the command and it's args.
TODO
- Remove ugly workaround helm templates
- Parse/replace environment variables on the command and it's arguments
- Parse deployment.yaml in a more generic way
- Review the logging/debug messages
- Return the return code of the command run
