Usage: consul config <subcommand> [options] [args]
|
|
|
|
This command has subcommands for interacting with Consul's Centralized
|
|
Configuration system. Here are some simple examples, and more detailed
|
|
examples are available in the subcommands or the documentation.
|
|
|
|
Write a config:
|
|
|
|
$ consul config write web.serviceconf.hcl
|
|
|
|
Read a config:
|
|
|
|
$ consul config read -kind service-defaults -name web
|
|
|
|
List all configs for a type:
|
|
|
|
$ consul config list -kind service-defaults
|
|
|
|
Delete a config:
|
|
|
|
$ consul config delete -kind service-defaults -name web
|
|
|
|
For more examples, ask for subcommand help or view the documentation.
