• Visualize your YAML files as Graph
• Generate additional info from your source code (simply define a YAML block and use this tool)

Takes in input:

• any YAML file
• any text file that has YAML between comments (like front matter)

Generates a dot script for Graphviz.

Given a sample deployment.yml file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 80

Run yml2dot like this:

$ yml2dot deployment.yml | dot -Tpng > deployment.png

and create this graph:

/*** 
Box:
  Object:
    - set
    - get
***/

public class Box {
    private Object object;

    public void set(Object object) {
        this.object = object;
    }
    public Object get() {
        return object;
    }
}

Use the -from and -to flags to mark your YAML block.

Run yml2dot like this:

$ yml2dot -from '/***' -to '***/' Box.java | dot -Tpng > Box.java.png

and create this graph:

If you have golang installed:

$ go install github.com/lucasepe/yml2dot@latest

This will create the executable under your $GOPATH/bin directory.

If you don't want to compile the sourcecode yourself, Here you can find the tool already compiled for:

• MacOS
• Linux
