NodePool

NodePool contains the name and configuration for a cluster's node pool. Node pools are a set of nodes (i.e. VM's), with a common configuration and specification, under the control of the cluster master. They may have a set of Kubernetes labels applied to them, which may be used to reference them during pod scheduling. They may also be resized up or down, to accommodate the workload. These upgrade settings control the level of parallelism and the level of disruption caused by an upgrade. maxUnavailable controls the number of nodes that can be simultaneously unavailable. maxSurge controls the number of additional nodes that can be added to the node pool temporarily for the time of the upgrade to increase the number of available nodes. (maxUnavailable + maxSurge) determines the level of parallelism (how many nodes are being upgraded at the same time). Note: upgrades inevitably introduce some disruption since workloads need to be moved from old nodes to new, upgraded ones. Even if maxUnavailable=0, this holds true. (Disruption stays within the limits of PodDisruptionBudget, if it is configured.) Consider a hypothetical node pool with 5 nodes having maxSurge=2, maxUnavailable=1. This means the upgrade process upgrades 3 nodes simultaneously. It creates 2 additional (upgraded) nodes, then it brings down 3 old (not yet upgraded) nodes at the same time. This ensures that there are always at least 4 nodes available.

details[]	object A list of messages that carry the error details. There is a common set of message types for APIs to use.
message	string A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.

StatusCondition

StatusCondition describes why a cluster or a node pool has a certain status (e.g., ERROR or DEGRADED).

Fields
canonicalCode	enum Canonical code of the condition.
Enum type. Can be one of the following:
OK	Not an error; returned on success HTTP Mapping: 200 OK
CANCELLED	The operation was cancelled, typically by the caller. HTTP Mapping: 499 Client Closed Request
UNKNOWN	Unknown error. For example, this error may be returned when a Status value received from another address space belongs to an error space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error. HTTP Mapping: 500 Internal Server Error
INVALID_ARGUMENT	The client specified an invalid argument. Note that this differs from FAILED_PRECONDITION. INVALID_ARGUMENT indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name). HTTP Mapping: 400 Bad Request
DEADLINE_EXCEEDED	The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire. HTTP Mapping: 504 Gateway Timeout
NOT_FOUND	Some requested entity (e.g., file or directory) was not found. Note to server developers: if a request is denied for an entire class of users, such as gradual feature rollout or undocumented allowlist, NOT_FOUND may be used. If a request is denied for some users within a class of users, such as user-based access control, PERMISSION_DENIED must be used. HTTP Mapping: 404 Not Found
ALREADY_EXISTS	The entity that a client attempted to create (e.g., file or directory) already exists. HTTP Mapping: 409 Conflict
PERMISSION_DENIED	The caller does not have permission to execute the specified operation. PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (use RESOURCE_EXHAUSTED instead for those errors). PERMISSION_DENIED must not be used if the caller can not be identified (use UNAUTHENTICATED instead for those errors). This error code does not imply the request is valid or the requested entity exists or satisfies other pre-conditions. HTTP Mapping: 403 Forbidden
UNAUTHENTICATED	The request does not have valid authentication credentials for the operation. HTTP Mapping: 401 Unauthorized
RESOURCE_EXHAUSTED	Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space. HTTP Mapping: 429 Too Many Requests
FAILED_PRECONDITION	The operation was rejected because the system is not in a state required for the operation's execution. For example, the directory to be deleted is non-empty, an rmdir operation is applied to a non-directory, etc. Service implementors can use the following guidelines to decide between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE: (a) Use UNAVAILABLE if the client can retry just the failing call. (b) Use ABORTED if the client should retry at a higher level. For example, when a client-specified test-and-set fails, indicating the client should restart a read-modify-write sequence. (c) Use FAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. For example, if an "rmdir" fails because the directory is non-empty, FAILED_PRECONDITION should be returned since the client should not retry unless the files are deleted from the directory. HTTP Mapping: 400 Bad Request
ABORTED	The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort. See the guidelines above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE. HTTP Mapping: 409 Conflict
OUT_OF_RANGE	The operation was attempted past the valid range. E.g., seeking or reading past end-of-file. Unlike INVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generate INVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generate OUT_OF_RANGE if asked to read from an offset past the current file size. There is a fair bit of overlap between FAILED_PRECONDITION and OUT_OF_RANGE. We recommend using OUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for an OUT_OF_RANGE error to detect when they are done. HTTP Mapping: 400 Bad Request
UNIMPLEMENTED	The operation is not implemented or is not supported/enabled in this service. HTTP Mapping: 501 Not Implemented
INTERNAL	Internal errors. This means that some invariants expected by the underlying system have been broken. This error code is reserved for serious errors. HTTP Mapping: 500 Internal Server Error
UNAVAILABLE	The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations. See the guidelines above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE. HTTP Mapping: 503 Service Unavailable
DATA_LOSS	Unrecoverable data loss or corruption. HTTP Mapping: 500 Internal Server Error
code	enum Machine-friendly representation of the condition Deprecated. Use canonical_code instead.
Enum type. Can be one of the following:
UNKNOWN	UNKNOWN indicates a generic condition.
GCE_STOCKOUT	GCE_STOCKOUT indicates that Google Compute Engine resources are temporarily unavailable.
GKE_SERVICE_ACCOUNT_DELETED	GKE_SERVICE_ACCOUNT_DELETED indicates that the user deleted their robot service account.
GCE_QUOTA_EXCEEDED	Google Compute Engine quota was exceeded.
SET_BY_OPERATOR	Cluster state was manually changed by an SRE due to a system logic error.
