Split configuration files

Sometimes you want to break your configuration file into several files. It may be useful in the following cases:

1. You want to switch nodes via modify the config file using tools like sed.
2. You copy other's configuration file and you want to overwrite some parts of it.

Example

Directory Structure:

# tree /etc/dae
/etc/dae
├── config.d
│  ├── dns.dae
│  ├── node.dae
│  └── route.dae
└── config.dae

Config files:

Notes about include paths:

• Relative paths (for example config.d/*.dae) are resolved relative to the directory of the entry config file (the file passed to dae -c ...), not relative to the current working directory.
• Absolute paths (for example /etc/dae/config.d/*.dae) are used as-is.
• For security reasons, dae only allows included files under the entry config directory.

These four files work together. Each tab shows a different file, not an alternative configuration.

config.dae

# config.dae

# load all dae files placed in ./config.d/
include {
    # Relative path example:
    config.d/*.dae

    # Absolute path example:
    /etc/dae/config.d/*.dae
}
global {
    tproxy_port: 12345

    log_level: warn

    tcp_check_url: 'http://cp.cloudflare.com'
    udp_check_dns: 'dns.google:53'
    check_interval: 600s
    check_tolerance: 50ms

    #lan_interface: eth0
    wan_interface: eth0
    allow_insecure: false

    dial_mode: domain
    disable_waiting_network: false
    auto_config_kernel_parameter: true
    sniffing_timeout: 30ms
}

dns.dae

# dns.dae
dns {
    upstream {
        alidns: 'udp://dns.alidns.com:53'
        googledns: 'tcp+udp://dns.google:53'
    }

    routing {
        request {
            qname(geosite:category-ads) -> reject
            qname(geosite:category-ads-all) -> reject
            fallback: alidns
        }
        response {
            upstream(googledns) -> accept
            !qname(geosite:cn) && ip(geoip:private) -> googledns
            fallback: accept
        }
    }
}

node.dae

# node.dae
node {
    node1: 'xxx'
    node2: 'xxx'
}

subscription {
    my_sub: 'https://www.example.com/subscription/link'
}

group {
    my_group {
        filter: subtag(my_sub) && !name(keyword: 'ExpireAt:')
        policy: min_moving_avg
    }

    local_group {
        filter: name(node1, node2)
        policy: fixed(0)
    }
}

route.dae

# route.dae
routing {
    pname(NetworkManager) -> direct
    dip(224.0.0.0/3, 'ff00::/8') -> direct
    dip(geoip:private) -> direct

    dip(1.14.5.14) -> direct

    domain(geosite:openai) -> local_group
    dip(geoip:cn) -> direct
    domain(geosite:cn) -> direct
    domain(geosite:category-scholar-cn) -> direct
    domain(geosite:geolocation-cn) -> direct


    fallback: my_group
}

Then run dae via:

sudo

sudo dae run -c /etc/dae/config.dae

root

dae run -c /etc/dae/config.dae
