Save time writing your Kubernetes microservices, coding only what truly matters.

This project is still in alpha, please be patient :)

Prerequisites

• An already installed and configured Kubernetes cluster
• An already configured kubectl to contact the Kubernetes cluster
• A docker image repository (for now tested only with GitLab image repo)
• A secret set in the Kubernetes cluster to access the docker image repository (for now it's mandatory)
• An Ingress in Kubernetes to access your microservices (for now it's mandatory)

Quick Start

Install via NPM

npm install -g kubefn

Read the docs

Read the full list of command and their parameters

kubefn

Initialize your microservice

kubefn bootstrap microservice-name

Navigate into the newly created directory

cd microservice-name

Configure your function

You can modify your parameters in the kubefn.config.js to configure kubefn.

module.exports = {
  "config": {
    "port": 3000,
    "imageregistry": "registry.gitlab.com", // Your docker image repository
    "imageregistrypath": "registry.gitlab.com/luno721/allstampsbackend", // The path where you want to save your image
    "imagepullsecret": "docker-repo-credential", // The secret you've set up in your kubernetes cluster to access to image repository
    "replicas": "2" // [optional] Number of replicas of the FN. Default: 2
  }
}

Run locally your microservice

Use this command to copy your ./src directory into the expressjs blueprint and run the expressjs server locally

kubefn run

Deploy your microservice

Creates the Kubernetes deployment and service for your function.

You still need to configure your Kubernetes Ingress to redirect traffic to your function.

kubefn deploy [semver_increment] # semver_increment: patch, minor, major

Rollback your microservice

Rollback to a previous version of your function

kubefn rollback <semver> # semver ex: 1.2.3

Destroy your microservice

kubefn destroy

Remember to fix your Kubernetes Ingress accordingly.
