yaml-diff

Usage

go install github.com/sters/yaml-diff/cmd/yaml-diff

or download from Releases.

yaml-diff path/to/foo.yaml path/to/bar.yaml

If the given yaml has a --- separated structure, then the two yaml's will get all the differences in their respective structures. The one with the smallest difference is considered to be the same structure and the difference is displayed.

The result structure is the same as based or target yaml but format (includes map fields order) is different.

Example

`make run-example`

You can try example directory.

$ go run cmd/yaml-diff/main.go example/a.yaml example/b.yaml
--- example/a.yaml
+++ example/b.yaml

  spec:
    selector:
      app: "MyApp"
    ports:
      -
-       port: 80
+       port: 8080
        targetPort: 9376
        protocol: "TCP"
  apiVersion: "v1"
  kind: "Service"
  metadata:
    name: "my-service"

  apiVersion: "apps/v1"
  kind: "Deployment"
  metadata:
    name: "app-deployment"
    labels:
      app: "MyApp"
  spec:
    selector:
      matchLabels:
        app: "MyApp"
    template:
      metadata:
        labels:
          app: "MyApp"
      spec:
        containers:
          -
            name: "app"
-           image: "my-app:1.0.0"
+           image: "my-app:1.1.0"
            ports:
              -
                containerPort: 9376
-   replicas: 3
+   replicas: 10

- foo: "missing-in-b"

  this:
    is:
      the: "same"

+ bar:
+   - "missing in a.yaml"

+ baz:
+   - "missing in a.yaml"

Even if reverse specify, it also worked properly.
