network

network is the polkadot network/chain to join and sync. Possible values are polkadot, kusama, rococo, westend and other chains supported by Parity Polkadot client.

p2pPort

p2pPort is p2p protocol tcp port.

nodePrivateKeySecretName

nodePrivateKeySecretName is Kubernetes secret name holding node Ed25519 private key in data field called key.
Node private can be generated using subkey tool from Parity Substrate.
1
# generate binary node key and save it in node.key file
2
subkey generate-node-key node.key
3
# convert node.key binary file into hexadecimal node.key.hex file
4
xxd -p -c 32 node.key > node.key.hex
Copied!
Create node private key secret:
1
kubectl create secret generic polkadot-node-key --from-file=key=node.key.hex
Copied!
polkadot-node-key secret can be used in your polkadot Node by updating .spec with nodePrivateKeySecretName: polkadot-node-key.

validator

validator enables validator.
Node must sync blocks in archive mode pruning: false if validator is enabled.

syncMode

syncMode is blockchain synchronization mode. Available values are fast and full.

pruning

pruning controls whether to keep only recent or all blocks. Setting pruning to false runs the node in archive mode.

retainedBlocks

retainedBlocks is the number of blocks to keep state for. It's only considered if .spec.pruning is set to true.

logging

logging is logging verboisty level. Available logging levels are error, warn, info, debug, and trace.

telemetry

telemetry enables connecting to telemetry server.

telemetryURL

telemetryURL is telemetry service URL. It's only considered if .spec.telemetry is set to true.

promethems

prometheus exposes prometheus exporter endpoint.

prometheusPort

prometheusPort is prometheus exporter port

rpc

rpc enables JSON-RPC server.

rpcPort

rpcPort is JSON-RPC server port.

ws

ws enables Websocket server.

wsPort

wsPort is Websocket server port.

corsDomains

corsDomains is browser origins allowed to access the JSON-RPC HTTP and WS servers.

resources

resources allocates compute and storage resources to the node.
Syntax
Type
Description
Default
cpu
string
number of cpu cores this node requires
4
cpuLimit
string
number of cpu cores this node is limited to
8
memory
string
memory this node requires
4Gi
memoryLimit
string
memory this node is limited to
8Gi
storage
string
disk space this node requires
80Gi
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.
