AWS API and Fabric tasks for deploying applications into EC2 instances
You need pip, build-essential and python-dev installed to run this:
Ubuntu :
sudo apt-get install python-pip build-essential python-dev Install package: :
pip install .Create requirements.txt file in the project root. This will install the package from Github. :
git+ssh://git@github.com:markosamuli/velvet.git@v0.5.6Create Python virtualenv for the project. :
mkvirtualenv PROJECT_NAMEInstall packages. :
pip install -r requirements.txtCreate acceess key: :
aws iam create-access-key --user-name USERNAME > ~/.aws/PROJECT_NAME.jsonConfigure Velvet and import your AWS access key JSON file. :
velvet-config --import-access-key ~/.aws/PROJECT_NAME.json
--aws-configConfigure Velvet and import your AWS credentials. :
velvet-config --import-credentials credentials.csvCreate config/velvet.yml file.
Example config/velvet.yml file for a project deployed to OpsWorks. :
# deployment configuration file version (minimum supported Velvet version number)
version: 0.4
# defaults for all environments
defaults:
# application name
app_name: application
# deployment package file name without extension
deploy_package: application
# S3 bucket for application deployment
deploy_bucket: application-deploy
# path to CloudFormation template files

# use compressed assets if avaiblable when publishing to S3
# assets are compressed with Grunt in the application build process
