OpenStack Ec2api Service

Project Description

OpenStack EC2 API README

Support of EC2 API for OpenStack. This project provides a standalone EC2 API service which pursues two goals:

  1. Implement VPC API
  2. Create a standalone service for EC2 API support.

Installation

Run install.sh

The EC2 API service gets installed on port 8788 by default. It can be changed before the installation in install.sh script.

The services afterwards can be started as binaries:

/usr/local/bin/ec2-api
/usr/local/bin/ec2-api-metadata
/usr/local/bin/ec2-api-s3

or set up as Linux services.

Installation in devstack:

In order to install ec2-api with devstack the following should be added to the local.conf or localrc the following line:

enable_plugin ec2-api https://git.openstack.org/openstack/ec2-api

To configure OpenStack for EC2 API metadata service:

for Nova-network

add:

[DEFAULT]
metadata_port = 8789
[neutron]
service_metadata_proxy = True

to /etc/nova.conf

then restart nova-metadata (can be run as part of nova-api service) and nova-network services.

for Neutron

add:

[DEFAULT]
nova_metadata_port = 8789

to /etc/neutron/metadata_agent.ini

then restart neutron-metadata service.

S3 server is intended only to support EC2 operations which require S3 server (e.g. CreateImage) in OpenStack deployments without regular object storage. It must not be used as a substitution for all-purposes object storage server. Do not start it if the deployment has its own object storage or uses a public one (e.g. AWS S3).

Usage

Download aws cli from Amazon. Create configuration file for aws cli in your home directory ~/.aws/config:

[default]
aws_access_key_id = 1b013f18d5ed47ae8ed0fbb8debc036b
aws_secret_access_key = 9bbc6f270ffd4dfdbe0e896947f41df3
region = us-east-1

Change the aws_access_key_id and aws_secret_acces_key above to the values appropriate for your cloud (can be obtained by “openstack ec2 credentials list” command).

Run aws cli commands using new EC2 API endpoint URL (can be obtained from openstack cli with the new port 8788) like this:

aws –endpoint-url http://10.0.2.15:8788 ec2 describe-instances

Supported Features and Limitations
