Description

Cookbook Version Dependency Status Code Climate Build Status

Chef cookbook to create a swap file of the recommended size considering the system memory.

This can be considered a general purpose cookbook but certainly not recommended for all cases.

Swap size is chosen based on the following documentation:

<table> <tr> <th>RAM Size</th> <th>Recommended Swap</th> </tr> <tr> <td>≤ 2 GB</td> <td>2 × RAM</td> </tr> <tr> <td>2 GB - 8 GB</td> <td>= RAM</td> </tr> <tr> <td>8 GB - 64 GB</td> <td>½ × RAM</td> </tr> <tr> <td>> 64 GB</td> <td>workload dependent</td> </tr> </table>

In case you already have swap in the system, creates another swap file with the difference if necessary.
