PyBuilder plugin to handle AWS functionality

pybuilder_aws_plugin

PyBuilder plugin to handle AWS functionality.

How to use the Plugin

Add plugin dependency to your build.py (will install directly from PyPi):

use_plugin('pypi:pybuilder_aws_plugin')

After this you have the following additional tasks, which are explained below:

• package_lambda_code

• upload_zip_to_s3

• upload_cfn_to_s3

@Task: package_lambda_code

This task assembles the Zip-file (a.k.a. the lambda-zip) which will be uploaded to S3 with the task upload_zip_to_s3. What is this task doing in detail?

Package all dependencies

Every entry in build.py that is specified by using project.depends_on is installed into a temporary directory using pip install -t and are then copied into the lambda-zip from there. The project property install_dependencies_index_url is respected and can be used to set a custom index url (e.g. internal devpi) for the installation.

Package all own modules

All modules which are found in src/main/python/ are copied directly into the lambda-zip.

Package all script files

The content of the scripts folder (src/main/scripts) in a PyBuilder project is normally intended to be placed in /usr/bin. This plugin assumes this directory contains script(s) including the lambda handler functions. Therefore all files under this folder are copied directly to the root layer (/) of the lambda-zip.

@Task: upload_zip_to_s3

This task uploads the generated zip to a S3 bucket. The bucket name is to be set as follows in build.py:

project.set_property('bucket_name', 'my_lambda_bucket')

The default acl for zips to be uploaded is bucket-owner-full-control. But if you need another acl you can overwrite this as follows in build.py:

project.set_property('lambda_file_access_control', '<wished_acl>')

Possible acl values are:

• private

• public-read

• public-read-write

• authenticated-read

• bucket-owner-read

• bucket-owner-full-control

Further, the plugin assumes that you already have a shell with enabled aws access (exported keys or .boto or …). For that take a look at e.g. afp-cli

The uploaded files will be placed in a directory with the version number, and in a latest/ directory, such as:

• v123/projectname.zip

• latest/projectname.zip

You can use the property bucket_prefix to add a prefix to the uploaded files. For example:

project.set_property('bucket_prefix', 'my_lambda/')

This will upload the files to the following files:

• my_lambda/v123/projectname.zip

• my_lambda/latest/projectname.zip

In an TeamCity Environment (teamcity_output = True) you can use the property teamcity_parameter to push en ##teamcity[setParameter name='' value=''] event to TeamCity and rewrite this parameter with the name of the uploaded zip file. For example:

project.set_property('teamcity_parameter', 'my_tc_parameter')

@Task: upload_cfn_to_s3

NOTE: This task is available for Python 2.7 and up, due to CFN-Sphere dependencies not being available for Python 2.6.

This task converts and uploads the CFN-Sphere template YAML files as JSON to a S3 bucket. The bucket name is to be set as follows in build.py:

project.set_property('bucket_name', 'my_lambda_bucket')

The default acl for JSON files to be uploaded is bucket-owner-full-control. But if you need another acl you can overwrite this as follows in build.py:

project.set_property('template_file_access_control', '<wished_acl>')

To define the templates you wish to be uploaded set the property as a list of tupels:

project.set_property('template_files',
    [
        ('path1','filename1'),
        ('path2','filename2'),
        ...
    ])

The uploaded files will be placed in a directory with the version number, and in a latest/ directory, such as:

• v123/filename1.json

• v123/filename2.json

• latest/filename1.json

• latest/filename2.json

You can use the property template_key_prefix to add a prefix to the uploaded files. For example:

project.set_property('template_key_prefix', 'my_lambda/')

This will upload the files to the following files:

• my_lambda/v123/filename1.json

• my_lambda/v123/filename2.json

• my_lambda/latest/filename1.json

• my_lambda/latest/filename2.json

The default acl for templates to be uploaded is bucket-owner-full-control. But if you need another acl you can overwrite this as follows in build.py:

project.set_property('template_file_access_control', '<wished_acl>')

Possible acl values are:

• private

• public-read

• public-read-write

• authenticated-read

• bucket-owner-read

• bucket-owner-full-control
