initializedConditions

Array of strings

Details:

Custom initialization flag, which is left blank by default.

Before CCE nodes are initialized, they are tainted with node.cloudprovider.kubernetes.io/uninitialized to prevent pods from being scheduled to them. When creating a node, you can specify the initializedConditions parameter to control the taint removal time. By default, the timeout interval is not configured.

Example:

1. Create a node and add parameter "initializedConditions": ["CCEInitial", "CustomedInitial"].

2. After custom initialization is complete, CCE will call a Kubernetes API (for example, PATCH /v1/nodes/{node_ip}/status) to update the node conditions by adding two labels of types CCEInitial and CustomedInitial and setting the status to True, as shown in the following:

status:
  conditions:
  - type: CCEInitial
    status: 'True'
  - type: CustomedInitial
    status: 'True'

1. CCE polls status.Conditions of nodes to check whether there are conditions of types CCEInitial and CustomedInitial. If such conditions exist and the status is True, the node initialization is complete and the initialization taint is removed.

2. initializedConditions allows you to configure a timeout period during node creation. For example, "initializedConditions": ["CCEInitial:15m", "CustomedInitial:15m"] indicates that the timeout period is 15 minutes. After the timeout period is reached, the initialization conditions will be automatically ignored and the initialization taint will be removed when CCE polls the node.

Constraints:

• The timeout interval in initializedConditions ranges from 1 to 99 seconds.

• Each value has 1 to 20 characters, which must consist of letters and digits.

• The maximum number of flags cannot exceed 2.

• The unit of the timeout period is minute (m).

• Number of ENIs bound to a BMS node (B) and number of ENIs being used by pods (U): U + Min < B < U + Max

• If the number of pre-bound ENIs on a BMS node is smaller than the minimum allowed, the system will bind more ENIs to make the numbers equal.

• If the number of pre-bound ENIs on a BMS node is larger than the maximum allowed, the system periodically unbinds ENIs (about every 2 minutes) to make the numbers equal.
