+# logstash
+
+This is intended to be the simplest possible working build of
+logstash. Building the dockerfile does the following:
+
+- download logstash tarball
+- unpack to /app
+- install contrib plugins
+
+## Download and test
+
+Download the image and check its version:
+
+```
+docker run -it rlister/logstash version
+```
+
+Run a simple agent to send stdin to stdout:
+
+```
+docker run -it rlister/logstash agent -e 'input { stdin { } } output { stdout {} }'
+hello world
+2014-11-14T07:37:27.719+0000 c99421891296 hello world
+```
+
+If you want to poke around in a container, override the default
+entrypoint:
+
+```
+docker run -it --entrypoint=bash rlister/logstash
+```
+
+## Reduce memory usage
+
+For running logstash as a simple shipper, you may want to limit
+footprint as follows:
+
+```
+export LS_HEAP_SIZE=128m
+docker run -d -e LS_HEAP_SIZE rlister/logstash ...
+```
+
+## Bindmount your own config
+
+```
+echo 'input { stdin { } } output { stdout {} }' > /tmp/logstash.conf
+docker run -d \
+  -v /tmp/logstash.conf:/app/logstash.conf \
+  rlister/logstash agent -f logstash.conf
+```
+
+## Bindmount a local log directory to ship it
+
+```
+echo 'input {file {path => "/log/*.log"}} output { stdout {} }' > /tmp/logstash.conf
+docker run -d \
+  -v /tmp/logstash.conf:/app/logstash.conf \
+  -v /var/log:/log \
+  rlister/logstash agent -f logstash.conf
+```
