secureCookies

secureCookies enables secure cookies for authentication.

logging

logging is logging verbosity level. Possible values are debug, info, warn, error, and panic.

resources

SyntaxTypeDescriptionDefault

cpu

string

number of cpu cores this node requires

2

cpuLimit

string

number of cpu cores this node is limited to

4

memory

string

memory this node requires

2Gi

memoryLimit

string

memory this node is limited to

4Gi

storage

string

disk space this node requires

20Gi

storageClass

string

Node volume storage class

Cluster's default storage class will be used as defined by cluster admin or cloud provider

memory and storage requests and limits must use the pattern ^[1-9][0-9]*[KMGTPE]i$ for example 1500Mi, 30Gi, and 1Ti.

cpu requests and limits must use the pattern ^[1-9][0-9]*m?$ for example 1000m (which is equal to 1), 1500m, 2, and 4.

cpuLimit can't be less than cpu.

memoryLimit can't be less than or equal to memory.

storageClass field is immutable, it cannot be changed after creation.
