Examples of correct configuration file structures
Here are files in all supported formats and with all possible configuration values of FrostFS applications. See node.yaml for configuration notes.
All parameters are correct, however, they are for informational purposes only. It is not recommended transferring these configs for real application launches.
Config files
- Storage node
- JSON:
node.json
- YAML:
node.yaml
- JSON:
- Inner ring
- YAML:
ir.yaml
- YAML:
- CLI

Multiple configs
You can split your configuration to several files.
For example, you can use separate yaml file for each shard or each service (pprof, prometheus).
You must use --config-dir
flag to process several configs:
$ ./bin/frotsfs-node --config ./config/example/node.yaml --config-dir ./dir/with/additional/configs
When the --config-dir
flag set, the application:
- reads all
*.y[a]ml
files from provided directory, - use Viper's MergeConfig functionality to produce the final configuration,
- files are being processing in alphanumerical order so that
01.yaml
may be extended with contents of02.yaml
, so if a field is specified in multiple files, the latest occurrence takes effect.
So if we have the following files:
# 00.yaml
logger:
level: debug
pprof:
enabled: true
address: localhost:6060
prometheus:
enabled: true
address: localhost:9090
# dir/01.yaml
logger:
level: info
pprof:
enabled: false
# dir/02.yaml
logger:
level: warn
prometheus:
address: localhost:9091
and provide the following flags:
$ ./bin/frotsfs-node --config 00.yaml --config-dir dir
result config will be:
logger:
level: warn
pprof:
enabled: false
address: localhost:6060
prometheus:
enabled: true
address: localhost:9091
