|---|---|---|---|
network is the public network name to join, like rinkeby.
network can't be provided in private networks, where .spec.genesis is not null.
network can't be updated (immutable).
highlyAvailable controls if Ethereum nodes will be scheduled on different Kubernetes nodes.
topologyKey is Kubernetes node label key used to distribute ethereum nodes pods on different kubernetes nodes.
bootnodes is ethereum node URLs for p2p network discovery and bootstraping.
bootnodes accepts ethereum node URL enodeURL or a reference to kotal Node in the form of name.namespace where namespace is optional if referenced node is in the same namespace.
Ethereum clients have hardcoded bootnodes for public main and test networks. bootnodes will override these bootnodes.
Support for OpenEthereum (parity) client has been deprecated. OpenEthereum team is working with Erigon on a smooth transition path for users. More information can be found here
client is the Ethereum client name powering the node.
client possible values are besu, geth, nethermind.
Only besu client can be used if network consensus is ibft2.
Only besu can be used in fixed difficulty proof of work networks, where spec.genesis.ethash.fixedDifficulty is not null.
coinbase is ethereum account to which mining rewards are paid.
coinbase is required if the node is mining miner: true.
corsDomains is a list of domains from which to accept cross-origin requests (browser enforced).
Default value * will be used if HTTP RPC server is enabled rpc: true or web socket server is enabled ws: true or graphQL server is enabled graphql: true.
graphql enables the GraphQL server.
Nethermind client doesn't support GraphQL.
Geth (Go-Ethereum) GraphQL server can be used only if RPC is enabled as of geth v1.9.19 release notes
graphqlPort GraphQL server listening port.
The default value 8547 will be used if the graphQL server is enabled graphql: true.
hosts is a list of host names to whitelist for RPC access (server enforced).
import is the ethereum account to import. Only for nodes running with geth or nethermind.
During account creation, it will be encrypted with the password, and during import it will be unlocked using the same password.
Nodes that import accounts can't enable HTTP RPC server, web socket server, or GraphQL server to prevent funds drainage if exposed to the internet.
Account must be imported if the node is running with geth or nethermind clients wants to be a signer or miner.
logging is Ethereum node logging verbosity level.
logging possible values are off, fatal, error, warn, debug, info, trace and all.
Different clients support different logging vrbosity levels as shown in the following table:
miner enables node mining or signing blocks.
nodePrivateKeySecretName is the node private key.
nodePrivateKeySecretName is required if the node is a boot node bootnode: true, or if besu node with client: besu is a signer in proof of authority clique network or validator in ibft2 network.
p2pPort is node p2p port for communication (TCP) and discovery (UDP).
resources allocates compute and storage resources to the node.
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.
rpc enables the HTTP RPC server.
rpcPort is the HTTP RPC server listening port.
Default value 8545 will be used if the HTTP RPC server is enabled with rpc: true.
rpcAPI is a list of RPC services to enable.
Default value ["web3", "eth", "net] will be used if HTTP RPC server is enabeld with rpc: true.
staticNodes is a set of trusted ethereum nodes to maintain connection to.
Static nodes are exempt from maximum peer and remote connection limits. Ethereum clients periodically initiating a connection to any unconnected static node.
staticNodes accepts ethereum node URL enodeURL or a reference to kotal Node in the form of name.namespace where namespace is optional if referenced node is in the same namespace.
Nethermind client removed support for beam sync which was activated by syncMode: light.
syncMode is Blockchain synchronization mode.
syncMode possible values are light, full, snap or fast.
light and snap sync modes are only supported by go-ethereum client.
ws enables the web socket server.
wsPort is the web socket server listening port.
The default value 8546 is used if the web socket server is enabled with ws: true.
wsAPI is a list of rpc services to enable.
the default value ["web3", "eth", "net] will be used if the web socket server is enabeld with ws: true.
genesis is the genesis block configuration.
Genesis block configuration genesis is required in private networks.
chainId is the chain id value used in transaction signature to prevent transactions reply eip155
chainId is required.
chainId can't reuse existing public network chain id to avoid transaction replay.
id is the network id used for p2p communications between network nodes in private networks.
id is required in private networks.
id can't be provided while joining a public network.
id can't be updated (immutable).
coinbase is the beneficiary (ethereum address) of mining reward.
coinbase is optional.
difficulty is the difficulty of the genesis block.
difficulty is optional.
mixHash is combined with the nonce to prove the effort spent to create a block.
mixHash is optional.
gasLimit is the total gas limit for all transactions in a block.
gasLimit is optional.
nonce is a random number used in block computation.
nonce is optional.
timestamp is block creation date.
timestamp is optional.
forks is an object, where the key is fork name and the value is the block number at which to activate this fork.
forks is optional.
if forks is missing, all forks will be activated at block 0 (genesis block) except DAO.
Later forks like muirglacier can't be activated before earlier forks like homestead. They must be ordered as in the following table:
accounts is an array of accounts to fund or store code.
accounts is optional.
accounts is recommended for networks where signers or validators are not rewarded with eth.
a single account has no defaults.
ethash is Proof of Work consensus engine configuration.
ethash is optional.
ethash can be set only in proof of work private networks.
ethash.fixedDifficulty has no default value.
ethash.fixedDifficulty is only supported by Hyperledger Besu Client client: besu
clique is Proof of Authority clique consensus engine configuration.
clique is optional.
clique can be set only in proof of authority clique private networks.
At least one signer in clique.signers is required.
ibft2 is IBFT2 engine configuration.
ibft2 is optional.
ibft2 can be set only in IBFT2 private networks.
At least one validator in ibft2.validators is required.
