# Wait for it
## Run a command only when port on host is available
### Tested on Alpine and Ubuntu
I needed to run a command in an Alpine Docker container only after another process (from other container) was open.
Based on https://github.com/vishnubob/wait-for-it. Many thanks!

#### Setup
* chmod +x wait-for-it.sh
* Change shebang line as needed:
* Alpine: #!/usr/bin/env sh
* Ubuntu: #!/usr/bin/env bash
#### Usage
```
./wait-for-it.sh -h host -p port [-c command] [-t timeout] [-q quiet]
-h Host or IP under test
-p TCP port under test
-c Command to execute if test succeeds
-t Timeout in seconds, zero for no timeout
-q Don't output any status messages
```
#### Examples
```
./wait-for-it.sh -h www.google.com -p 80 -t 5 -c "echo Google is up" -q
./wait-for-it.sh -h www.google.com -p 8080 -t 5
