Go Virtual Machine Kube (vmkube)

 Check last build on Travis-CI

Go-Lang Virtual Machine environment manager. This package allow to define projects and build infrastructures on local or remote cloud providers

Prerequisites

• Go (tested with version 1.12)
• Docker and Docker-Machine

One of following :

• VMWare Fusion
• VMWare Workstation Player
• Virtual Box (VMWare Utilities on mac : brew install vagrant-vmware-fusion, on windows/linux: VDDK65)
• Microsoft Hyper-V
• Any of the cloud provider supported by docker

In order to define machine OSs, you can use any of the supported ISOs

Goals

Define a virtual machine remote/local manager based on docker-machine drivers. It defines a smart and simple command-line/web interface to manage environments. It provides features to define project and deployment plans for infrastructures and applications. Domain, Network and Host management level and hierarchy are main concepts in the VMKube philosophy. WMKube provides development and deployment environments: You have to define an initial project, you can manager the networks, domains, hosts and a staging phase. When you close the project, you are ready to delete it or, alternatively, to build and run the infrastructure.

What is provided?

Provided features:

• Project definition procedures

• Project staging/un-staging procedures

• Project build procedures

• Infrastructure build procedures

• Infrastructure/Project inspection procedures

• Custom Deployment plans with main providers (VMKubelet, Ansible, Helm for Kubernetes, ...)

• Digital Control and multi vendor instances (Machine and Cloud-Machines can be defined)

• Multiple project/infrastructure information export formats

Machine Providers:

See Docker-Machine Drivers

To compile and run this project you have to check availability of following software:

• Go (tested with version 1.8)
• Docker and Docker-Machine
• Test and Utility GOLang packages (UUID Package, Unit Test) and GO SSH Terminal, YAML Parser

Architecture

Configuration

Checkout and test this repository

Go in you GOPATH/src folder and type :

 go get github.com/stretchr/testify
 go get github.com/satori/go.uuid
 go get golang.org/x/crypto/ssh/terminal
 go get gopkg.in/yaml.v2
 git clone https://github.com/hellgate75/vmkube.git

or simply :

 go get github.com/stretchr/testify
 go get github.com/satori/go.uuid
 go get golang.org/x/crypto/ssh/terminal
 go get gopkg.in/yaml.v2
 go get github.com/hellgate75/vmkube

Build

It's present a make file that returns an help on the call :

make

Provided Makefile help returns following options :

make [all|init|test|build|exe|run|clean|install]
all: test build exe run
init: get required external packages
test: run unit test
build: build the module
exe: make executable for the module
clean: clean module C objects
run: exec the module code
install: install the module in go libs

Alternatively you can execute following commands :

• go get github.com/stretchr/testify to download unit test external package
• go get github.com/satori/go.uuid to download UUID management external package
• go get golang.org/x/crypto/ssh/terminal to download SSH terminal external package
• go get gopkg.in/yaml.v2 to download YAML parser
• go build . to build the project
• go test to run unit and integration test on the project
• go run main.go to execute the project
• go build --buildmode exe . to create an executable command
• go install to install the executable command

Execution

The tool provides an help section, describing commands, sub-commands and has a nested help level for commands details.

The help is available executing :

• vmkube help General Help
• vmkube help [command] Detailed Command syntax helper

Import / Alter Project Commands provides a sample for the expected input format. Import and Export of components is provided in following file formats:

• JSON - standard JSON language
• XML - Untagged and un-described XML format (Pure XML tag sequence, no XML definition or version is accepted).
• YAML - standard YAML format.

In this release the command list is composed by following keys :

• help : Show generic commands help
• start-infra : Start an existing Infrastructure
• stop-infra : Stop a Running Infrastructure
• restart-infra : Restart a Running Infrastructure
• destroy-infra : Destroy a specific Infrastructure
• backup-infra : Backup a specific Infrastructure to a backup file
• recover-infra : Recover a specific Infrastructure from a backup file
• infra-status : Require information about a specific Infrastructure
• list-all-infra : Require list of all Infrastructures
• list-projects : Require list of all available projects
• project-status : Require information about a specific projects
• define-project : Creates a new project
• alter-project : Modify existing project, e.g.: open, close project or add, modify, delete items
• info-project : Provides information about project elements definition
• delete-project : Delete existing project
• build-project : Build and existing project and create/modify an infrastructure
• import-project : Import project from existing configuration
• export-project : Export existing project configuration
