SIA for AWS EC2

Configuration

SIA AWS requires a configuration file to be present in the /etc/sia/sia_config with the following required attributes if the property does not want to use the default settings which require the use of the EC2 instance-profile role in the name format of <property-domain-name>.<property-service-name>-service:

{
    "version": "1.0.0",
    "service": "property-service-name",
    "accounts": [
        {
            "domain":  "property-domain-name",
            "account": "account-aws-id"
        }
    ]
}

The AWS Account administrator must create an IAM Role called <property-domain-name>.<property-service-name> and this role must be setup with a trusted relationship with the role that the EC2 instance is configured to run as.

SIA Configuration file is also required if the user wants to change the default user/group settings that the private key is owned by. By default, the private key is owned by user root and readable by group athenz. If the user wants to provide access to their service identity private key to another user, it can be accomplished by adding the user to the group athenz. If the user wants to change the user and group values, a config file must be dropped with the following optional fields:

{
    "version": "1.0.0",
    "service": "property-service-name",
    "accounts": [
        {
            "domain":  "property-domain-name",
            "account": "account-aws-id",
            "user": "unix-username",
            "group": "unix-groupname"
        }
    ]
}
