+# logrotate
+
+[![Build Status](https://travis-ci.org/nickhammond/ansible-logrotate.svg?branch=master)](https://travis-ci.org/nickhammond/ansible-logrotate)
+
+Installs logrotate and provides an easy way to setup additional logrotate scripts by
+specifying a list of directives.
+
+## Requirements
+
+None
+
+## Role Variables
+
+**logrotate_scripts**: A list of logrotate scripts and the directives to use for the rotation.
+
+* name - The name of the script that goes into /etc/logrotate.d/
+* path - Path to point logrotate to for the log rotation
+* paths - A list of paths to point logrotate to for the log rotation.
+* options - List of directives for logrotate, view the logrotate man page for specifics
+* scripts - Dict of scripts for logrotate (see Example below)
+
+```
+logrotate_scripts:
+  - name: rails
+    path: "/srv/current/log/*.log"
+    options:
+      - weekly
+      - size 25M
+      - missingok
+      - compress
+      - delaycompress
+      - copytruncate
+```
+
+```
+logrotate_scripts:
+  - name: rails
+    paths:
+        - "/srv/current/scare.log"
+        - "/srv/current/hide.log"
+    options:
+      - weekly
+      - size 25M
+      - missingok
+      - compress
+      - delaycompress
+      - copytruncate
+```
+
+## Dependencies
+
+None
+
+## Example Playbook
+
+Setting up logrotate for additional Nginx logs, with postrotate script.
+
+```
+- hosts: all
+  vars:
+    logrotate_scripts:
+      - name: nginx-options
+        path: /var/log/nginx/options.log
+        options:
+          - daily
+          - weekly
+          - size 25M
+          - rotate 7
+          - missingok
+          - compress
+          - delaycompress
+          - copytruncate
+
+      - name: nginx-scripts
+        path: /var/log/nginx/scripts.log
+        options:
+          - daily
+          - weekly
+          - size 25M
+        scripts:
+          postrotate: "echo test"
+
+  roles:
+    - ansible-logrotate
+```
+
+## Testing locally
+
+This role is already configured to run on travis CI within a test playbook but it's useful to be able to run and debug a role locally which can be done via Vagrant and the `ansible_local` provisioner.
+
+To run the test playbook locally within a Vagrant virtual machine:
+
+```
+cd tests
+vagrant up --provision
+```
