public static final class NodePool.UpgradeSettings extends GeneratedMessageV3 implements NodePool.UpgradeSettingsOrBuilder
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.
These upgrade settings configure the upgrade strategy for the node pool.
Use strategy to switch between the strategies applied to the node pool.
If the strategy is ROLLING, use max_surge and max_unavailable to control
the level of parallelism and the level of disruption caused by upgrade.
- 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 controls the number of nodes that can be simultaneously
unavailable.
(maxUnavailable + maxSurge) determines the level of parallelism (how
many nodes are being upgraded at the same time).
If the strategy is BLUE_GREEN, use blue_green_settings to configure the
blue-green upgrade related settings.
- standard_rollout_policy is the default policy. The policy is used to
control the way blue pool gets drained. The draining is executed in the
batch mode. The batch size could be specified as either percentage of the
node pool size or the number of nodes. batch_soak_duration is the soak
time after each batch gets drained.
- node_pool_soak_duration is the soak time after all blue nodes are
drained. After this period, the blue pool nodes will be deleted.
