Introduction

This is a simple and straightforward CLI that allows you to update your Kubernetes configuration files dynamically during a build.

Installation

go get -u github.com/oshalygin/k8s-config

Usage

Usage of k8s-config:
  -type string
        The Kubernetes configuration type(default: "deployment")
  -file-path string
        The location of the configuration file
  -image string
        The full image name, 'oshalygin/foobar:1.0.0'
  -tag string
        If just the tag is provided without the image,
        then only the tag will be updated on the existing
        image name.

Example

# Call the utility at the specified path with the 
# appropriate command line arguments.

k8s-config --type=deployment \
             --file-path=../test-files/deployment.yaml \  
             --image='oshalygin/my-website-image:1.0.3'
             
# Although it is recommended to be explicit, here is
# the minimum amount of flags you can pass and still
# use the utility effectively

k8s-config --tag=1.03
           --file-path=../test-files/deployment.yaml 

Command Line Arguments

type: The Kubernetes type that you want to update. Depending on the type, the utility will parse it different, this value is required.

image: The new image name

file-path: The location of the configuration file

tag: If the image is excluded and just the version is passed in, you can easily just bump the version of the container image(assuming there's a single image per pod)

Limitations

Note: This list will change accordingly over the development of this utility.

• Only yaml configuration files(Not JSON)
• Only deployment types.
• Only single container deployment configurations.
