# Kubernetes UI
Summary
----------
> RPC Server, RPC Client and Web interface for Kubernetes
>
> WORK IN-PROGRESS
Environment
----------
> build all and tested on GNU/Linux
GNU/Linux: Ubuntu 20.04_x64 LTS
Kubernetes (Master node, Worker node x2)
Docker (+ Docker Private Registry)
Python: v3.8.10 (pip 20.0.2)
Go: go1.20.4 linux/amd64
Apache2
cURL
Prerequisites
----------
```sh
* VirtualBox: Kubernetes
- Master node (+ Backend: JSON RPC API Server)
- Worker node1 (+ Docker & Private Registry)
- Worker node2
* kubernetes
- (optional) $HOME/.kube/config permission for user
* Docker
Install: https://docs.docker.com/engine/install/
* Docker Private Registry
$ sudo docker pull registry:latest
$ sudo docker run -d --restart=always -p 5000:5000 registry:latest
// Test Image: Ubuntu 20.04, Apache2, Tomcat9, MariaDB, ...
$ sudo docker build -f Dockerfile_test_image --tag test_img_apm:1.0 .
$ sudo docker tag test_img_apm:1.0 (Docker Private Registry IP):5000/test_img_apm:1.0
$ sudo docker push (Docker Private Registry IP):5000/test_img_apm:1.0
```
Dependencies
----------
```sh
// Python3
// for Python RPC client code test
$ sudo apt-get install python3 python3-pip
// Apache2
// for Web interface test
$ sudo apt-get install apache2
// cURL
// for JSON RPC client test
$ sudo apt-get install curl
// Golang
$ wget https://go.dev/dl/go1.20.4.linux-amd64.tar.gz
$ sudo tar xzvf go1.20.4.linux-amd64.tar.gz -C /usr/local/
$ echo "export PATH=$PATH:/usr/local/go/bin" >> $HOME/.profile
// Golang modules
