config.yml reference

The config.yml file generated in your blockchain folder uses key-value pairs to describe the development environment for your blockchain.

Only a default set of parameters is provided. If more nuanced configuration is required, you can add these parameters to the config.yml file.

accounts

A list of user accounts created during genesis of the blockchain.

Key	Required	Type	Description
name	Y	String	Local name of a key pair. An account name must be listed to gain access to the account tokens after the blockchain is launched.
coins	Y	List of Strings	Initial coins with denominations. For example, "1000token"
address	N	String	Account address in Bech32 address format.
mnemonic	N	String	Mnemonic used to generate an account. This field is ignored if address is specified.

accounts example

accounts:
  - name: alice
    coins: ["1000token", "100000000stake"]
  - name: bob
    coins: ["500token"]
    address: cosmos1adn9gxjmrc3hrsdx5zpc9sj2ra7kgqkmphf8yw

build

Key	Required	Type	Description
main	N	String	When an app contains more than one main Go package, required to define the path of the chain's main package.
binary	N	String	Name of the node binary that is built, typically ends with d.
ldflags	N	List of Strings	ldflags to set version information for go applications.

build example

build:
  binary: "mychaind"
  ldflags: [ "-X main.Version=development", "-X main.Date=01/05/2022T19:54" ]

build.proto

Key	Required	Type	Description
path	N	String	Path to protocol buffer files. Default: "proto".
third_party_paths	N	List of Strings	Path to third-party protocol buffer files. Default: ["third_party/proto", "proto_vendor"].

client

Configures and enables client code generation. To prevent Ignite CLI from regenerating the client, remove the client property.

client.vuex

client:
  vuex:
    path: "vue/src/store"

Generates TypeScript Vuex client for the blockchain in path on serve and build commands.

client.openapi

client:
  openapi:
    path: "docs/static/openapi.yml"

Generates OpenAPI YAML file in path. By default this file is embedded in the node's binary.

faucet

The faucet service sends tokens to addresses. The default address for the web user interface is http://localhost:4500.

Key	Required	Type	Description
name	Y	String	Name of a key pair. The name key pair must be in accounts.
coins	Y	List of Strings	One or more coins with denominations sent per request.
coins_max	N	List of Strings	One or more maximum amounts of tokens sent for each address.
host	N	String	Host and port number. Default: :4500
rate_limit_window	N	String	Time after which the token limit is reset (in seconds).

faucet example

faucet:
  name: faucet
  coins: ["100token", "5foo"]
  coins_max: ["2000token", "1000foo"]
  port: 4500

validator

A blockchain requires one or more validators.

Key	Required	Type	Description
name	Y	String	The account that is used to initialize the validator. The name key pair must be in accounts.
staked	Y	String	Amount of coins to bond. Must be less than or equal to the amount of coins in the account.

validator example

accounts:
  - name: alice
    coins: ["1000token", "100000000stake"]
validator:
  name: user1
  staked: "100000000stake"

init.home

The path to the data directory that stores blockchain data and blockchain configuration.

init example

init:
  home: "~/.myblockchain"

init.config

Overwrites properties in config/config.toml in the data directory.

init.app

Overwrites properties in config/app.toml in the data directory.

init.client

Overwrites properties in config/client.toml in the data directory.

init.client example

init:
  client:
    keyring-backend: "os"

host

Configuration of host names and ports for processes started by Ignite CLI:

host example

host:
  rpc: ":26659"
  p2p: ":26658"
  prof: ":6061"
  grpc: ":9091"
  api: ":1318"

genesis

Use to overwrite values in genesis.json in the data directory to test different values in development environments. See Genesis Overwrites for Development.
