description: Amazon Web Services driver for machine
keywords: machine, Amazon Web Services, driver
title: Amazon Web Services
---
Create machines on [Amazon Web Services](https://aws.amazon.com).
To create machines on [Amazon Web Services](https://aws.amazon.com), you must supply two parameters: the AWS Access Key ID and the AWS Secret Access Key.
## Configuring credentials
Before using the amazonec2 driver, ensure that you've configured credentials.
### AWS credential file
One way to configure credentials is to use the standard credential file for Amazon AWS `~/.aws/credentials` file, which might look like:
[default]
aws_access_key_id = AKID1234567890
aws_secret_access_key = MY-SECRET-KEY
On Mac OS or various flavors of Linux you can install the [AWS Command Line Interface](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html#cli-quick-configuration) (`aws cli`) in the terminal and use the `aws configure` command which guides you through the creation of the credentials file.
This is the simplest method, you can then create a new machine with:
$ docker-machine create --driver amazonec2 aws01
### Command line flags
Alternatively, you can use the flags `--amazonec2-access-key` and `--amazonec2-secret-key` on the command line:
$ docker-machine create --driver amazonec2 --amazonec2-access-key AKI******* --amazonec2-secret-key 8T93C******* aws01
### Environment variables
You can use environment variables:
$ export AWS_ACCESS_KEY_ID=AKID1234567890
$ export AWS_SECRET_ACCESS_KEY=MY-SECRET-KEY
$ docker-machine create --driver amazonec2 aws01
## Options

## Security Group
A security group is created and associated to the host. This security group has the following ports opened inbound:
- ssh (22/tcp)
- docker (2376/tcp)
- swarm (3376/tcp), only if the node is a swarm master
If you specify a security group yourself using the `--amazonec2-security-group` flag, the above ports are checked and opened and the security group is modified.
If you want more ports to be opened such as application-specific ports, use the AWS console and modify the configuration manually.
## VPC ID
Your default VPC ID is determined at the start of a command. In some cases, either because your account does not have a default VPC, or you do not want to use the default one, you can specify a VPC with the `--amazonec2-vpc-id` flag.
### To find the VPC ID:
1. Login to the AWS console.
2. Go to **Services -> VPC -> Your VPCs**.
3. Locate the VPC ID you want from the *_VPC_* column.
4. Go to **Services -> VPC -> Subnets**. Examine the _Availability Zone_ column to verify that zone `a` exists and matches your VPC ID. For example, `us-east1-a` is in the `a` availability zone. If the `a` zone is not present, you can create a new subnet in that zone or specify a different zone when you create the machine.
### To create a machine with a non-default VPC-ID:
$ docker-machine create --driver amazonec2 --amazonec2-access-key AKI******* --amazonec2-secret-key 8T93C********* --amazonec2-vpc-id vpc-****** aws02
This example assumes the VPC ID was found in the `a` availability zone. Use the`--amazonec2-zone` flag to specify a zone other than the `a` zone. For example, `--amazonec2-zone c` signifies `us-east1-c`.
## VPC Connectivity
Docker Machine uses SSH to complete the set up of instances in EC2 and requires the ability to access the instance directly.
If you use the flag `--amazonec2-private-address-only`, ensure that you can access the new instance from within the internal network of the VPC, such as a corporate VPN to the VPC, a VPN instance inside the VPC, or using `docker-machine` from an instance within your VPC.
Configuration of VPCs is beyond the scope of this guide. However, the first step in troubleshooting is making sure that you are using private subnets that follow the design guidance in the [AWS VPC User Guide](http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Scenario2.html) and have some form of NAT available so that the setup process can access the internet to complete the setup.
## Custom AMI and SSH username
The default SSH username for the default AMIs is `ubuntu`.
You need to change the SSH username only if the custom AMI you use has a different SSH username.
You can change the SSH username with the `--amazonec2-ssh-user` according to the AMI you selected with the `--amazonec2-ami` option.
