+# Genprocessor: Docker
+
+`http` - http server that serves up the DCAE Nifi jars as files under the path `/nifi-jars`
+`job` - background job that continuously polls the onboarding API for components and generates jars from components
+
+The usage here will assume the use of a docker volume to persist data.
+
+Create a volume:
+
+```
+docker volume create genprocessor
+```
+
+## job
+
+Build:
+
+```
+$ cd ../
+$ docker build -t genprocessor-job -f docker/job/Dockerfile .
+```
+
+Run:
+
+```
+docker run -v genprocessor:/work -e GENPROC_ONBOARDING_API_HOST=http://some-hostname/onboarding -d genprocessor-job
+```
+
+NOTE: Above onboarding API is to the one running in iLab.
+
+Run as part of the stack:
+
+```
+docker run -v genprocessor:/work --link onboarding-api:onboarding-api -d genprocessor-job
+```
+
+## http
+
+Build:
+
+```
+$ cd http
+$ docker build -t genprocessor-http .
+```
+
+Run:
+
+```
+$ docker run -p 8080:80 -d -v genprocessor:/www/data:ro genprocessor-http
+```
+
