Build the project

Make sure you have golang 1.13+ on your platform

$ git clone [email protected]:shift-left-netconfig/cluster-topology-analyzer.git
$ cd cluster-topology-analyzer
$ go mod download
$ make

Using Docker Image

If you have access to us.icr.io/gitsecure registry namespace, then you can download the image and run it from there

$ docker run us.icr.io/gitsecure/gitsecure-nettop:1.0.0 -h

Usage

$ ./bin/net-top -h
Usage of ./bin/net-top:
  -commitid string
    	gitsecure run id
  -dirpath string
    	input directory path
  -gitbranch string
    	git repository branch
  -giturl string
    	git repository url
  -outputfile string
    	file path to store results

Example

1. Clone a sample source code repository that you want to scan

$ cd $HOME
$ [email protected]:nadgowdas/microservices-demo.git

2. Point topology analyzer to this sample repo

$ ./bin/net-top -dirpath $HOME/microservices-demo -commitid 9133fdc043b20be15f958339e96564eac04bed6e -giturl https://github.com/nadgowdas/microservices-demo -gitbranch matser
