FrostFS REST Gateway configuration file

This section contains detailed FrostFS REST Gateway configuration file description including default config values and some tips to set up configurable values.

There are some custom types used for brevity:

• duration -- string consisting of a number and a suffix. Suffix examples include s (seconds), m (minutes), ms ( milliseconds).

Structure

Section	Description
no section	General parameters
wallet	Wallet configuration

prometheus	Prometheus configuration

General section

scheme: [ http ]
cleanup-timeout: 10s
graceful-timeout: 15s
max-header-size: 1000000

listen-address: localhost:8080
listen-limit: 0
keep-alive: 3m
read-timeout: 30s
write-timeout: 30s

tls-listen-address: localhost:8081
tls-certificate: /path/to/tls/cert
tls-key: /path/to/tls/key
tls-ca: /path/to/tls/ca
tls-listen-limit: 0
tls-keep-alive: 3m
tls-read-timeout: 30s
tls-write-timeout: 30s

Parameter	Type	Default value	Description
scheme	[]string	[http]	The listeners to enable, this can be repeated and defaults to the schemes in the swagger spec.
cleanup-timeout	duration	10s	Grace period for which to wait before killing idle connections.
graceful-timeout	duration	15s	Grace period for which to wait before shutting down the server.
max-header-size	int	1000000	Controls the maximum number of bytes the server will read parsing the request header's keys and values, including the request line. It does not limit the size of the request body.
listen-address	string	localhost:8080	The IP and port to listen on.
listen-limit	int	0	Limit the number of outstanding requests. 0 means no limit
keep-alive	duration	3m	Sets the TCP keep-alive timeouts on accepted connections.
read-timeout	duration	30s	Maximum duration before timing out read of the request. It prunes dead TCP connections (e.g. closing laptop mid-download).
write-timeout	duration	30s	Maximum duration before timing out write of the response.
tls-listen-address	string	localhost:8081	The IP and port to listen on for TLS.
tls-certificate	string		The certificate file to use for secure connections.
tls-key	string		The private key file to use for secure connections (without passphrase).
tls-ca	string		The certificate authority certificate file to be used with mutual tls auth.
tls-listen-limit	int	0	Limit the number of outstanding requests for TLS. 0 means no limit
tls-keep-alive	duration	3m	Sets the TCP keep-alive timeouts on accepted connections for TLS.
tls-read-timeout	duration	30s	Maximum duration before timing out read of the request for TLS. It prunes dead TCP connections (e.g. closing laptop mid-download).
tls-write-timeout	duration	30s	Maximum duration before timing out write of the response for TLS.

wallet section

wallet:
  path: /path/to/wallet.json
  address: NfgHwwTi3wHAS8aFAN243C5vGbkYDpqLHP
  passphrase: pwd

Parameter	Type	Default value	Description
path	string		Path to the wallet.
address	string		Account address to get from wallet. If omitted default one will be used.
passphrase	string		Passphrase to decrypt wallet.

pool section

pool:
  node-dial-timeout: 10s
  healthcheck-timeout: 15s
  rebalance-timer: 60s
  error-threshold: 100

  # Nodes configuration
  # This configuration makes the gateway use the first node (node1.frostfs:8080)
  # while it's healthy. Otherwise, gateway uses the second node (node2.frostfs:8080)
  # for 10% of requests and the third node (node3.frostfs:8080) for 90% of requests.
  # Until nodes with the same priority level are healthy
  # nodes with other priority are not used.
  # The lower the value, the higher the priority.
  peers:
    0:
      address: node1.frostfs:8080
      priority: 1
      weight: 1
    1:
      address: node2.frostfs:8080
      priority: 2
      weight: 0.1
    2:
      address: node3.frostfs:8080
      priority: 2
      weight: 0.9

Parameter	Type	Default value	Description
node-dial-timeout	duration	10s	Timeout to connect to a node.
healthcheck-timeout	duration	15s	Timeout to check node health during rebalance.
rebalance-timer	duration	60s	Interval to check node health.
error-threshold	uint32	100	The number of errors on connection after which node is considered as unhealthy.

peers section

Parameter	Type	Default value	Description
address	string		Address of storage node.
priority	int	1	It allows to group nodes and don't switch group until all nodes with the same priority will be unhealthy. The lower the value, the higher the priority.
weight	float	1	Weight of node in the group with the same priority. Distribute requests to nodes proportionally to these values.

logger section

logger:
  level: debug

Parameter	Type	Default value	Description
level	string	debug	Logging level. Possible values: debug, info, warn, error, dpanic, panic, fatal.

pprof section

Contains configuration for the pprof profiler.

pprof:
  enabled: true
  address: localhost:8091

Parameter	Type	Default value	Description
enabled	bool	false	Flag to enable the service.
address	string	localhost:8091	Address that service listener binds to.

prometheus section

Contains configuration for the prometheus metrics service.

prometheus:
  enabled: true
  address: localhost:8092

Parameter	Type	Default value	Description
enabled	bool	false	Flag to enable the service.
address	string	localhost:8092	Address that service listener binds to.
