| By default, docker must be run as root, or via sudo privileges. You may also allow a user to run docker directly by adding the user to the 'docker' group. | |

| Be aware that this may allow for privilege escalation for that user, should they escape the container. | |

| for centos 6 - needs EPEL repo | |
| NOTE for CentOS users | |
| You can install EPEL by running yum install epel-release. The package is included in the CentOS Extras repository, enabled by default. | |
| If you already have the (unrelated) docker package installed, it will conflict with docker-io. There's a bug report filed for it. To proceed with docker-io installation, please remove docker first. | |
| install the docker-io package which will install Docker on our host. | |
| $ sudo yum install docker-io | |
| and then | |
| sudo service docker start | |
| If we want Docker to start at boot, we should also: | |
| $ sudo chkconfig docker on | |
| Now let's verify that Docker is working. First we'll need to get the latest centos image. | |
| $ sudo docker pull centos | |
| Next we'll make sure that we can see the image by running: | |
| $ sudo docker images centos | |

| Hello from Docker. | |
| This message shows that your installation appears to be working correctly. | |
| To generate this message, Docker took the following steps: | |
| 1. The Docker client contacted the Docker daemon. | |
| 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. | |
| 3. The Docker daemon created a new container from that image which runs the | |
| executable that produces the output you are currently reading. | |
| 4. The Docker daemon streamed that output to the Docker client, which sent it | |
| to your terminal. | |
| To try something more ambitious, you can run an Ubuntu container with: | |
| $ docker run -it ubuntu bash | |

| For best performance the metadata should be on a different spindle than the data, or even better on an SSD. | |
| If using a block device for device mapper storage, it is best to use lvm to create and manage the thin-pool volume. This volume is then handed to Docker to exclusively create snapshot volumes needed for images and containers. | |
| Managing the thin-pool outside of Docker makes for the most feature-rich method of having Docker utilize device mapper thin provisioning as the backing storage for Docker’s containers. The highlights of the lvm-based thin-pool management feature include: automatic or interactive thin-pool resize support, dynamically changing thin-pool features, automatic thinp metadata checking when lvm activates the thin-pool, etc. | |

| As a fallback if no thin pool is provided, loopback files will be created. Loopback is very slow, but can be used without any pre-configuration of storage. It is strongly recommended that you do not use loopback in production. Ensure your Docker daemon has a --storage-opt dm.thinpooldev argument provided. | |
| If setting up a new metadata pool it is required to be valid. This can be achieved by zeroing the first 4k to indicate empty metadata, like this: | |
| dd if=/dev/zero of=$metadata_dev bs=4096 count=1 | |
| --storage-opt dm.use_deferred_deletion=true \ | |
| --storage-opt dm.use_deferred_removal=true | |
