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 is p2p protocol tcp port.nodePrivateKeySecretName is Kubernetes secret name holding node Ed25519 private key in data field called key.# generate binary node key and save it in node.key file
subkey generate-node-key node.key
# convert node.key binary file into hexadecimal node.key.hex file
xxd -p -c 32 node.key > node.key.hex
Create node private key secret:
kubectl create secret generic polkadot-node-key --from-file=key=node.key.hex
polkadot-node-key secret can be used in your polkadot Node by updating .spec with nodePrivateKeySecretName: polkadot-node-key.validator enables validator.Node must sync blocks in archive mode
pruning: false if validator is enabled.syncMode is blockchain synchronization mode. Available values are fast and full.pruning controls whether to keep only recent or all blocks. Setting pruning to false runs the node in archive mode.retainedBlocks is the number of blocks to keep state for. It's only considered if .spec.pruning is set to true.logging is logging verboisty level. Available logging levels are error, warn, info, debug, and trace.telemetry enables connecting to telemetry server.telemetryURL is telemetry service URL. It's only considered if .spec.telemetry is set to true.prometheus exposes prometheus exporter endpoint.prometheusPort is prometheus exporter portrpc enables JSON-RPC server.rpcPort is JSON-RPC server port.ws enables Websocket server.wsPort is Websocket server port.corsDomains is browser origins allowed to access the JSON-RPC HTTP and WS servers.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.Last modified 1yr ago
