+# Using cloud-init to Customize Docker on CentOS Atomic Host
+
+These files show an example of how to use `cloud-init` on a public cloud provider (AWS is used in this example) to customize the configuration and behavior of the Docker daemon on a CentOS Atomic Host instance.
+
+## Contents
+
+* **cloud-config.yml**: This is the `cloud-init` configuration file that does the configuration of the Docker daemon on the instance. No modifications to this file should be necessary.
+
+* **launch.sh**: This Bash shell script uses the AWS CLI to gather information from AWS and then launch an instance in your default VPC.
+
+* **README.md**: The file you're currently reading.
+
+## Prerequisites
+
+Before you can use this environment, there are a few things you'll need to do:
+
+1. You'll need to install **and** configure the AWS CLI. The launch script provided in this environment assumes that the AWS CLI is installed, configured, and working as expected.
+
+2. In your default VPC, you'll need to either a) modify the default security group to allow inbound SSH; or b) create a security group called "default" that allows inbound SSH. If you prefer to use a name other than "default", you'll need to modify `launch.sh` with the updated name of the security group to use.
+
+3. You'll need to have a working SSH keypair in AWS.
+
+## Instructions
+
+1. If you are using a security group other than one named "default" (as described in the "Prerequisites" section), edit `launch.sh` and modify the command that looks up the security group ID accordingly.
+
+2. Edit `launch.sh` to specify the correct AWS keypair to use when launching the instance.
+
+3. Launch the instance using `./launch.sh`. This launch script assumes that the AWS CLI is working, and that the `cloud-config.yml` file is in the same directory.
+
+4. Using the AWS CLI or the AWS Console, determine the public IP address assigned to the instance you just created.
+
+5. Use SSH to connect to the instance (use the username "centos" to connect). Once logged into the instance, use `systemctl status docker.service` to verify that the Docker daemon is running and that the systemd drop-in located in `/etc/systemd/system/docker.service.d` has been loaded.
+
+6. While logged into the instance, use `ss -lnt` to show that a process (the Docker daemon) is listening on TCP port 2375.
+
+7. Verify the Docker daemon is working across the network by running `sudo docker -H tcp://127.0.0.1:2375 ps`.
+
+Enjoy!
