# Docker as a local cloud provider
jclouds-docker is a local cloud provider modelled on [docker](http://www.docker.io). Similar to other jclouds supported
providers, it supports the same portable abstractions offered by jclouds.
##Setup
Please follow these steps to configure your workstation for jclouds-docker:
- install the latest Docker release (please visit https://docs.docker.com/installation/)
If you are using `docker-machine` then it can also manage certificates and help you setup `DOCKER_CERT_PATH` and `DOCKER_HOST` environment variables.
Assuming these environment variables are setup correctly there are no further setups steps are required.
Live tests then can now be run: `mvn -Plive integration-test`
#How it works
--------------- -------------
| Image(s) | | Node(s) |
--------------- -------------
--------- docker remote api ----------------------------------------
| jclouds | ---------------------------> | DOCKER_HOST |
--------- ----------------------------------------
##Components
- jclouds \- acts as a java client to access to docker features
- DOCKER_HOST \- hosts Docker API, NB: jclouds-docker assumes that the latest Docker is installed
- Image \- it is a docker image that can be started.
- Node \- is a docker container
## Assumptions
- jclouds-docker assumes that the images specified using the template are ssh'able.
--------------
#Notes:
- jclouds-docker is still at alpha stage please report any issues you find at [jclouds issues](https://issues.apache.org/jira/browse/JCLOUDS)
- jclouds-docker has been tested on Mac OSX, it might work on Linux iff vbox is running and set up correctly. However, it has never been tried on Windows.
--------------
#Troubleshooting
As jclouds docker support is quite new, issues may occasionally arise. Please follow these steps to get things going again:
1. Remove all containers
$ docker rm -f `docker ps -a`
2. remove all the images
$ docker rmi -f `docker images -q`
