Required Values

The required values are mostly the Chainlink environment variables described in their documentation.

Name	Chainlink Environment Variable	Type	Default Value
explorer_access_key	EXPLORER_ACCESS_KEY	string	""
explorer_secret	EXPLORER_URL	string	""
root	ROOT	string	"/chainlink"
log_level	LOG_LEVEL	string	"debug"
eth_chain_id	ETH_CHAIN_ID	string	"4"
chainlink_tls_port	CHAINLINK_TLS_PORT	string	"0"
secure_cookies	SECURE_COOKIES	string	"false"
allow_origins	ALLOW_ORIGINS	string	"*"
eth_url	ETH_URL	string	""
database_locking_mode	DATABASE_LOCKING_MODE	string	"lease"
p2p_bootstrap_peers	P2P_BOOTSTRAP_PEERS	string	""
feature_offchain_reporting	FEATURE_OFFCHAIN_REPORTING	string	"true"
chainlink_dev	CHAINLINK_DEV	string	"true"
p2p	see below	object	see below

The p2p key is an object with the following default value:

  p2p:
    enabled: true
    port: 10000
    elastic_ip_alloc_id: ''
    public_ip: ''

p2p.enabled isn't a Chainlink environment variable, but it allows you to choose whether you need the following P2P environment variables enabled or not. If p2p.enabled is true the following environment variables will be set:

• P2P_LISTEN_PORT (p2p.port)
• P2P_ANNOUNCE_PORT (p2p.port)
• P2P_ANNOUNCE_IP (p2p.public_ip)

p2p.elastic_ip_alloc_id will always be used for the AWS Load Balancer EIP allocations (see Chainlink Service).

Required Values

The required values are mostly the Chainlink Adapters environment variables described here.

Name	Chainlink Environment Variable	Type	Default Value
ea_port	EA_PORT	string	see below
api_key	API_KEY	string	""
timeout	TIMEOUT	string	30000
cache_enabled	CACHE_ENABLED	string	"false"
rate_limit_enabled	RATE_LIMIT_ENABLED	string	"true"
warmup_enabled	WARMUP_ENABLED	string	"true"
rate_limit_api_provider	RATE_LIMIT_API_PROVIDER	string	see below
rate_limit_api_tier	RATE_LIMIT_API_TIER	string	see below
request_coalescing_enabled	REQUEST_COALESCING_ENABLED	string	"true"
request_coalescing_interval	REQUEST_COALESCING_INTERVAL	string	"100"
request_coalescing_interval_max	REQUEST_COALESCING_INTERVAL_MAX	string	"1000"
request_coalescing_interval_coefficient	REQUEST_COALESCING_INTERVAL_COEFFICIENT	string	"2"
request_coalescing_entropy_max	REQUEST_COALESCING_ENTROPY_MAX	string	"0"
warmup_unhealthy_treshold	WARMUP_UNHEALTHY_THRESHOLD	string	"3"
warmup_subscription_ttl	WARMUP_SUBSCRIPTION_TTL	string	"360000"
log_level	LOG_LEVEL	string	"info"
debug	DEBUG	string	"false"
api_verbose	API_VERBOSE	string	"false"
experimental_metrics_enabled	EXPERIMENTAL_METRICS_ENABLED	string	"true"
metrics_name	METRICS_NAME	string	see below
retry	RETRY	string	"1"

All the above values are created inside the adapter object, e.g. with nomics:

nomics:
  config:
    ea_port: 1111
    api_key: ""
    timeout: 30000
    cache_enabled: false
    rate_limit_enabled: true
    warmup_enabled: true
    rate_limit_api_provider: 'nomics'
    rate_limit_api_tier: "https://api.nomics.com/v1"
    request_coalescing_enabled: true
    request_coalescing_interval: 100
    request_coalescing_interval_max: 1000
    request_coalescing_interval_coefficient: 2
    request_coalescing_entropy_max: 0
    warmup_unhealthy_treshold: 3
    warmup_subscription_ttl: 3600000
    log_level: "info"
    debug: false
    api_verbose: false
    experimental_metrics_enabled: true
    metrics_name: nomics
    retry: 1

The following keys depend on the provider, you probably won't have to change their values:

• ea_port, e.g.: 1111
• rate_limit_api_provider, e.g.: nomics
• rate_limit_api_tier, e.g.: https://api.nomics.com/v1
• metrics_name, e.g.: nomics
