## wait-for-it
# wait-for-it

`wait-for-it.sh` is a pure bash script that will wait on the availability of a host and TCP port. It is useful for synchronizing the spin-up of interdependent services, such as linked docker containers. Since it is a pure bash script, it does not have any external dependencies.

## Usage

```
```sh
wait-for-it.sh host:port [-s] [-t timeout] [-- command args]
-h HOST | --host=HOST Host or IP under test
-p PORT | --port=PORT TCP port under test

For example, let's test to see if we can access port 80 on www.google.com, and if it is available, echo the message `google is up`.

```
```sh
$ ./wait-for-it.sh www.google.com:80 -- echo "google is up"

You can set your own timeout with the `-t` or `--timeout=` option. Setting the timeout value to 0 will disable the timeout:

```
```sh
$ ./wait-for-it.sh -t 0 www.google.com:80 -- echo "google is up"
wait-for-it.sh: waiting for www.google.com:80 without a timeout
wait-for-it.sh: www.google.com:80 is available after 0 seconds

The subcommand will be executed regardless if the service is up or not. If you wish to execute the subcommand only if the service is up, add the `--strict` argument. In this example, we will test port 81 on www.google.com which will fail:

```
```sh
$ ./wait-for-it.sh www.google.com:81 --timeout=1 --strict -- echo "google is up"
wait-for-it.sh: waiting 1 seconds for www.google.com:81

If you don't want to execute a subcommand, leave off the `--` argument. This way, you can test the exit condition of `wait-for-it.sh` in your own scripts, and determine how to proceed:

```
```sh
$ ./wait-for-it.sh www.google.com:80
wait-for-it.sh: waiting 15 seconds for www.google.com:80
wait-for-it.sh: www.google.com:80 is available after 0 seconds
