If you can script it, you can HTTP it.

## What's Kapow!
|
|
|
|
Say we have a nice cozy **shell command** that solves our problem. *Kapow!* lets
|
|
us easily **turn that into an HTTP API**.
|
|
|
|
|
|
### Let's see this with an example
|
|
|
|
We want to expose **log entries** for files not found on our **Apache Web
|
|
Server**, as an HTTP API. With *Kapow!* we just need to write this file:
|
|
|
|
```bash
|
|
[apache-host]$ cat search-apache-errors.pow
|
|
kapow route add /apache-errors - <<-'EOF'
|
|
cat /var/log/apache2/access.log | grep 'File does not exist' | kapow set /response/body
|
|
EOF
|
|
```
|
|
|
|
and then, run it using Kapow!
|
|
|
|
```bash
|
|
[apache-host]$ kapow server --bind 0.0.0.0:8080 search-apache-errors.pow
|
|
```
|
|
|
|
finally, we can read from the just-defined endpoint:
|
|
|
|
```bash
|
|
[another-host]$ curl http://apache-host:8080/apache-errors

### Why Kapow! shines in these cases
|
|
|
|
- We can share information **without having to grant SSH access** to anybody.
|
|
- We can share information easily **over HTTP**.
|
|
- We can **limit** what is executed.
