+# Docker curl Timer
+You need a way to perform a curl inside a container every `TIMER` secs? And you don't want to use a cron job, because a Linux based image is too heavy for this work, right?
+Curl-Timer is your light solution.
+
+Curl Timer is a very light Docker image that let you perform a curl in a configurable amount of time.
+
+You can specify the `HTTP_VERB`, `URL`, `AUTH_TYPE` and `AUTH` you want to use.
+
+Simply try it:
+
+```
+docker run \
+-e HTTP_VERB='POST' \
+-e URL='https://example.com' \
+-e AUTH_TYPE='Basic' \
+-e AUTH='MyToken' \
+-e TIMER=600 \
+agiuliano/curl-timer
+```
+
+
+Or use it in your `docker-compose.yml` file:
+
+```yaml
+timer:
+    build: agiuliano/curl-timer
+    environment:
+        HTTP_VERB: POST
+        URL: https://example.com
+        AUTH_TYPE: Basic
+        AUTH: MyToken
+        TIMER: 600
+```
