# 远程可读存储 `remote_read` 主要用于可读远程存储配置，主要包含以下参数： - url: 访问地址 - remote_timeout: 请求超时时间 其代码结构体为： ``` // RemoteReadConfig is the configuration for reading from remote storage. type RemoteReadConfig struct { URL *URL `yaml:"url,omitempty"` RemoteTimeout model.Duration `yaml:"remote_timeout,omitempty"` // We cannot do proper Go type embedding below as the parser will then parse // values arbitrarily into the overflow maps of further-down types. HTTPClientConfig HTTPClientConfig `yaml:",inline"` // Catches all undefined fields and must be empty after parsing. XXX map[string]interface{} `yaml:",inline"` } ``` 一份完整的配置大致为: ``` # The URL of the endpoint to query from. url: <string> # Timeout for requests to the remote read endpoint. [ remote_timeout: <duration> | default = 30s ] # Sets the `Authorization` header on every remote read request with the # configured username and password. basic_auth: [ username: <string> ] [ password: <string> ] # Sets the `Authorization` header on every remote read request with # the configured bearer token. It is mutually exclusive with `bearer_token_file`. [ bearer_token: <string> ] # Sets the `Authorization` header on every remote read request with the bearer token # read from the configured file. It is mutually exclusive with `bearer_token`. [ bearer_token_file: /path/to/bearer/token/file ] # Configures the remote read request's TLS settings. tls_config: [ <tls_config> ] # Optional proxy URL. [ proxy_url: <string> ] ``` 注意： remote_read 属于试验阶段，慎用，因为在以后的版本中可能发生改变。
