waitforsocket

waitforsocket is a tool that lets you wait for a service or multiple services to become available. It understands http, https, and raw TCP sockets.

waitforsocket will continue to try all non-connected sockets until the absolute timeout is reached, or enough connections are made. If enough connections are established before the absolute timeout, the process will exit 0, otherwise, the process will exit with a non-zero status code indicating the required connections were not made.

Usage

Usage: waitforsocket [--absTimeout ARG] [--required ARG] [--timeout ARG]
                     targets...
  Wait for network things.

Available options:
  --absTimeout ARG         absolute timeout (default: 0)
  --required ARG           how many connections required (0 = all) (default: 0)
  --timeout ARG            connect/retry timeout (ms) (default: 5000)
  -h,--help                Show this help text

When waiting for services, there are three configuration parameters to consider:

1. How long are we willing to wait for any results at all?
2. How long are we willing to wait for any given connection to be established?
3. How many connections are required in order to claim success?
