EC2 provider configuration¶

The EC2 provider accepts a number of configuration options, that can be specified in the environments.yaml file under an ec2 provider section.

access-key:

The AWS access key to utilize for calls to the AWS APIs.

secret-key:

The AWS secret key to utilize for calls to the AWS APIs.

ec2-uri:

The EC2 api endpoint URI, by default points to ec2.amazonaws.com

region:

The EC2 region, by default points to us-east-1. If 'ec2-uri' is specified, it will take precedence.

s3-uri:

The S3 api endpoint URI, by default points to s3.amazonaws.com

control-bucket:

An S3 bucket unique to the environment, where some runtime metadata and charms are stored.

juju-origin:

Defines where juju should be obtained for installing in machines. Can be set to a "lp:..." branch url, to "ppa" for getting packages from the official juju PPA, or to "distro" for using packages from the official Ubuntu repositories.

If this option is not set, juju will attempt to detect the correct origin based on its run location and the installed juju package.

ssl-hostname-verification:

When using SSL based API endpoints, this boolean controls whether or not to verify the certificate against the local trusted certificate authorities.

default-instance-type [DEPRECATED]:

The instance type to be used for machines launched within the juju environment. Acceptable values are based on EC2 instance type API names like t1.micro or m1.xlarge.

This functionality is replaced via setting constraints on a service or environment.

default-image-id [DEPRECATED]:

The default amazon machine image to utilize for machines in the juju environment. If not specified the default image id varies by region.

This functionality is replaced via setting constraints on a service or environment.

default-series [DEPRECATED]:

The default Ubuntu series to use (oneiric, for instance). EC2 images and charms referenced without an explicit series will both default to the value of this setting.

The charm specifies which series to be use now.

Additional configuration options, not specific to EC2:

authorized-keys-path:

The path to a public key to place onto launched machines. If no value is provided for either this or authorized-keys then a search is made for some default public keys "id_dsa.pub", "id_rsa.pub", "identity.pub". If none of those exist, then a LookupError error is raised when launching a machine.

authorized-keys:

The full content of a public key to utilize on launched machines.
