Wait Service

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

Help

`` 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 runnpm 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 runnpm 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 runnpm start`

USAGE: wait-service ... --json ... --tcp ... --timeout --uds ...

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

The Config File

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

For a TCP service, the object format is

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

For a UDS service, the object format is

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