Zombie Service Diff

Diff two zombie service states.

It takes a current and a wanted state and returns an object containing add, remove and keep properties.

Install

npm install --save @zombiec0rn/zombie-service-diff

Use

require('@zombiec0rn/zombie-service-diff')(current, wanted)
// => { add : [], remove : [], keep : [] }

Fingerprint

It can on some engines be quite hard to extract the exact configuration used to start a service. Because of this we support a fingerprint property on services being diffed, that will take precedence over the object hash.

  {
    "id": "yolo",
    "image": "zombiec0rn/yolo:1.0.0",
    "fingerprint": "0c0d289f8743bac4719509a04261c3f2d359a58d"
  }

The module also exports a fingerprint function that can be used to create the fingerprint.

require('@zombiec0rn/zombie-service-diff').fingerprint({
  id: 'yolo',
  image: 'zombiec0rn/yolo:1.0.0'
})
// => 0c0d289f8743bac4719509a04261c3f2d359a58d
