备注

Cli utility is intent to be used to observe library abilities and for debug purposes.Multitracker can be used in CI/CD deploy pipeline to make sure that some set of resources is ready or done before proceeding deploy process.

• There are 3 modes of resource tracking: multitrack, follow(DEPRECATION) and rollout(DEPRECATION)

multitrack最简单使用:

cat << EOF | kubedog multitrack
{
  "StatefulSets": [
    {
      "ResourceName": "mysts1",
      "Namespace": "myns"
    }
  ],
  "Deployments": [
    {
      "ResourceName": "mydeploy22",
      "Namespace": "myns"
    }
  ]
}
EOF

实例1:

$ echo '{
    "StatefulSets":[{"ResourceName":"mysts1","Namespace":"myns"}],
    "Deployments":[{"ResourceName":"mydeploy22","Namespace":"myns"}]
  }' | kubedog multitrack
$ kubectl -n myns get po
$ kubectl -n myns delete po mydeploy22-5bxxxxx-xxx mysts1-0 mysts1-1 --force --grace-period=0
// 再监测
$ echo '{
    "StatefulSets":[{"ResourceName":"mysts1","Namespace":"myns"}],
    "Deployments":[{"ResourceName":"mydeploy22","Namespace":"myns"}]
  }' | kubedog multitrack

实例2:

$ echo '{
    "DaemonSets":[{"ResourceName":"mysts1","Namespace":"myns"}],
    "StatefulSets":[{"ResourceName":"mysts1","Namespace":"myns"}],
    "Deployments":[{"ResourceName":"mydeploy22","Namespace":"myns"}]
  }' | kubedog multitrack --output-prefix="     "
$ kubectl -n myns get po
$ kubectl -n myns delete po mydeploy22-5bxxxxx-xxx mysts1-0 mysts1-1 myds1-xxxxx --force --grace-period=0
// 再监测:
$ echo '{
    "DaemonSets":[{"ResourceName":"mysts1","Namespace":"myns"}],
    "StatefulSets":[{"ResourceName":"mysts1","Namespace":"myns"}],
    "Deployments":[{"ResourceName":"mydeploy22","Namespace":"myns"}]
  }' | kubedog multitrack --output-prefix="     "

实例3:

          {

            "Namespace":"myns"
          },
          {

            "SkipLogsForContainers":["two", "three"]
          }
        ],
        "StatefulSets":[
