This process requires you to have an Amazon Web Services (AWS) account. If you have not signed up for one yet, it can obtained at http://aws.amazon.com.
You should start by generating a generic configuration file for Juju, using the command:
This will generate a file,
environments.yaml, which will live in your
~/.juju/ directory (and will create the directory if it doesn't already
Note: If you have an existing configuration, you can use
generate-config --show to output the new config file, then copy and paste
relevant areas in a text editor etc.
The generic configuration sections generated for AWS will look something like this:
# https://jujucharms.com/docs/config-aws.html amazon: type: ec2 # region specifies the EC2 region. It defaults to us-east-1. # # region: us-east-1 # access-key holds the EC2 access key. It defaults to the # environment variable AWS_ACCESS_KEY_ID. # # access-key: <secret> # secret-key holds the EC2 secret key. It defaults to the # environment variable AWS_SECRET_ACCESS_KEY. # # secret-key: <secret> # image-stream chooses a simplestreams stream to select OS images # from, for example daily or released images (or any other stream # available on simplestreams). # # image-stream: "released"
This is a simple configuration intended to run on EC2 with S3 permanent
storage. Values for the default setting can be changed simply by editing this
file, uncommenting the relevant lines and adding your own settings. All you
need to do to get this configuration to work is to either set the
AWS_SECRET_ACCESS_KEY via environment variables, or
uncomment and add the values to the configuration file.
You can retrieve these values easily from your AWS Management Console at http://console.aws.amazon.com. Click on your name in the top-right and then the "Security Credentials" link from the drop down menu.
Under the "Access Keys" heading click the "Create New Root Key" button. You
will be prompted to "Download Key File" which by default is named rootkey.csv.
Open this file to get the access-key and secret-key for the
The region: value corresponds to the AWS regions.
By default, Juju will deploy units to m3.medium instances, unless otherwise constrained.
Features supported by Juju-owned instances running within AWS:
Consistent naming, tagging, and the ability to add user-controlled tags to created instances. See Instance naming and tagging for more information.
The selection (placement) of availability zones, if existing, when adding a machine:
juju machine add zone=us-east-1a
