+# Building Asterisk into a Docker Container Image
+The following set of steps should leave you with a Docker container that
+is relatively small, built from your local checked out source, and even
+provides you with a nice little RPM too!
+
+## Build the package container image
+Build the package container image. This uses FPM[1] so no `spec` files and
+such are necessary.
+```
+docker build --pull -f contrib/docker/Dockerfile.packager -t asterisk-build .
+```
+
+## Build your Asterisk RPM from source
+Build the Asterisk RPM from the resulting container image.
+```
+docker run -ti \
+    -v $(pwd):/application:ro \
+    -v $(pwd)/out:/build \
+    -w /application asterisk-build \
+    /application/contrib/docker/make-package.sh 13.6.0
+```
+> **NOTE**: If you need to build this on a system that has SElinux enabled
+> you'll need to use the following command instead:
+> ```
+> docker run -ti \
+>     -v $(pwd):/application:Z \
+>     -v $(pwd)/out:/build:Z \
+>     -w /application asterisk-build \
+>     /application/contrib/docker/make-package.sh 13.6.0
+> ```
+
+## Create your Asterisk container image
+Now create your own Asterisk container image from the resulting RPM.
+```
+docker build --rm -t madsen/asterisk:13.6.0-1 -f contrib/docker/Dockerfile.asterisk .
+```
