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.Syntax | Type | Description |

memory and storage requests and limits must use the pattern
