oc/kubectl 补丁替换整行

Question

I am using oc patch with op to replace one string in deployment, following is the command:-

oc patch dc abc --type='json' -p='[{"op": "replace", "path": "/spec/template/spec/containers/0/image", "value": "ab-repository/" },{"op": "replace", "path": "/spec/template/spec/containers/0/image", "value": "bc-repository/" }]'

what it is doing is it changes below:-

Before:- ab-repository/ab:1.0.0
After:- bc-repository/

what I want is this:-

Before:- ab-repository/ab:1.0.0
After:- bc-repository/ab:1.0.0

Please let me know what i am doing wrong here.

Below is the YAML

apiVersion: apps.openshift.io/v1
kind: DeploymentConfig
metadata:
  name: ruleengine
  namespace: apps
spec:
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    name: ruleengine
  strategy:
    activeDeadlineSeconds: 21600
    resources: {}
    rollingParams:
      intervalSeconds: 1
      updatePeriodSeconds: 1
    type: Rolling
  template:
    metadata:
      creationTimestamp: null
      labels:
        name: ruleengine
    spec:
      containers:
      - image: ab-repository/ab:1.0.0 ### containers should be provided in the form of an array

Answer 1

The ' replace ' operation works like remove/add entire value:

This operation is functionally identical to a "remove" operation for a value, followed immediately by an "add" operation at the same location with the replacement value.

There's no such JSON patch operation as replace value partially ( RFC6902 , RFC7386 )

You can get image like:

oc get dc ruleengine -o=jsonpath='{..image}'

Then manipulate the value with sed and use it in 'oc patch'
