Amazon EC2

There are several ways to install Docker on AWS EC2:

• amazonquickstart or
• amazonstandard or
• amazonvagrant

You'll need an AWS account first, of course.

Amazon QuickStart

1. Choose an image:
   • Open http://cloud-images.ubuntu.com/locator/ec2/
   • Enter amd64 precise in the search field (it will search as you type)
   • Pick an image by clicking on the image name. An EBS-enabled image will let you use a t1.micro instance. Clicking on the image name will take you to your AWS Console.
2. Tell CloudInit to install Docker:
   • Enter #include https://get.docker.io into the instance User Data. CloudInit is part of the Ubuntu image you chose and it bootstraps from this User Data.
3. After a few more standard choices where defaults are probably ok, your AWS Ubuntu instance with Docker should be running!

If this is your first AWS instance, you may need to set up your Security Group to allow SSH. By default all incoming ports to your new instance will be blocked by the AWS Security Group, so you might just get timeouts when you try to connect.

Installing with get.docker.io (as above) will create a service named dockerd. You may want to set up a docker group <dockergroup> and add the ubuntu user to it so that you don't have to use sudo for every Docker command.

Once you've got Docker installed, you're ready to try it out -- head on over to the ../use/basics or ../examples/index section.

Standard Ubuntu Installation

If you want a more hands-on installation, then you can follow the ubuntu_linux instructions installing Docker on any EC2 instance running Ubuntu. Just follow Step 1 from amazonquickstart to pick an image (or use one of your own) and skip the step with the User Data. Then continue with the ubuntu_linux instructions.

Use Vagrant

And finally, if you prefer to work through Vagrant, you can install Docker that way too. Vagrant 1.1 or higher is required.

1. Install vagrant from http://www.vagrantup.com/ (or use your package manager)

2. Install the vagrant aws plugin

   vagrant plugin install vagrant-aws

3. Get the docker sources, this will give you the latest Vagrantfile.

   git clone https://github.com/dotcloud/docker.git

4. Check your AWS environment.

   Create a keypair specifically for EC2, give it a name and save it to your disk. I usually store these in my ~/.ssh/ folder.

   Check that your default security group has an inbound rule to accept SSH (port 22) connections.

5. Inform Vagrant of your settings

   Vagrant will read your access credentials from your environment, so we need to set them there first. Make sure you have everything on amazon aws setup so you can (manually) deploy a new image to EC2.

   export AWS_ACCESS_KEY_ID=xxx
   export AWS_SECRET_ACCESS_KEY=xxx
   export AWS_KEYPAIR_NAME=xxx
   export AWS_SSH_PRIVKEY=xxx

   The environment variables are:

   • AWS_ACCESS_KEY_ID - The API key used to make requests to AWS
   • AWS_SECRET_ACCESS_KEY - The secret key to make AWS API requests
   • AWS_KEYPAIR_NAME - The name of the keypair used for this EC2 instance
   • AWS_SSH_PRIVKEY - The path to the private key for the named keypair, for example ~/.ssh/docker.pem

   You can check if they are set correctly by doing something like

   echo $AWS_ACCESS_KEY_ID

6. Do the magic!

   vagrant up --provider=aws

   If it stalls indefinitely on [default] Waiting for SSH to become available..., Double check your default security zone on AWS includes rights to SSH (port 22) to your container.

   If you have an advanced AWS setup, you might want to have a look at https://github.com/mitchellh/vagrant-aws

7. Connect to your machine

   vagrant ssh

8. Your first command

   Now you are in the VM, run docker

   sudo docker

Continue with the hello_world example.
