Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed in the character string. When creating a node, you can specify the initial value for this parameter and this field is not returned during query. In using node pools, the initial value can be specified in the node template and this field is returned during query. In other scenarios, this field is not returned during query.

When creating a node, you can specify the initial value for this parameter and this field is not returned during query. In using node pools, the initial value can be specified in the node template and this field is returned during query. In other scenarios, this field is not returned during query.

initializedConditions

Array of strings

Custom initialization flag.

Before CCE nodes are initialized, they are tainted with node.cloudprovider.kubernetes.io/uninitialized to prevent pods from being scheduled to them.

CCE supports custom initialization flags. After receiving the initializedConditions parameter, CCE converts the parameter value into a node label and provisions the label with the node, for example, cloudprovider.openvessel.io/inject-initialized-conditions=CCEInitial_CustomedInitial.

After the node is labeled, its status.Conditions is polled to check whether the type of conditions has a flag name, such as CCEInitial and CustomedInitial. If all input flags exist and their status is True, the node initialization is complete and the initialization taint is removed.

• Use only letters and digits. Max. characters: 20.
• Max. flags: 2.

When Device Mapper is used, you are advised to set dockerBaseSize to a value less than or equal to 80 GB.
