Wait Service is a pure rust program to test and wait on the availability of multiple services.

EXAMPLES:
wait-service --tcp localhost:27017 --tcp localhost:27018   -t 5 -- npm start  # Wait for localhost:27017 and localhost:27018 (max 5 seconds) and then run `npm start`
wait-service --tcp localhost:27017 --uds /var/run/app.sock -t 0 -- npm start  # Wait for localhost:27017 and /var/run/app.sock (forever) and then run `npm start`
wait-service --uds /var/run/app.sock --json /path/to/json       -- npm start  # Wait for /var/run/app.sock and other services defined in the json file (max 60 seconds) and then run `npm start`

    wait-service [OPTIONS] <COMMAND>...

    <COMMAND>...    Command to execute after service is available

OPTIONS:
    -t, --timeout <TIMEOUT>    Set the timeout in seconds, zero for no timeout [default: 60]
        --tcp <TCP>...         Test and wait on the availability of TCP services
        --uds <UDS>...         Test and wait on the availability of UDS services [aliases: unix]

    -V, --version              Print version information

The Config File

With the --json option, you can input one or more JSON files to import your TCP / UDS services. The content of each file needs to be a JSON array of objects.

For a TCP service, the object format is

{
    "host": "example.com",
    "port": 443
}

For a UDS service, the object format is

{
    "uds": "/path/to/socket_file"
}
