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:

use_plugin('pypi:pybuilder_aws_plugin')

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

@Task: package_lambda_code

This task assembles the zip file which will be uploaded to S3 with the second task. What is this task doing in detail?

Package all own modules

All modules which are found in src/main/python/ where put directly into the temporary folder, which will zipped later.

Package all dependencies

Every entry in build.py with depends_on is installed into the zip file. The target path for pip install points directly to the temporary folder, which will then be zipped.

Package all script files

The content in the scripts folder (src/main/scripts) of an pybuilder project is normally intended to go to /usr/bin. This plugin sees this folder as a folder with script(s) including lambda handler functions. Therefore all files under this folder are put at the root layer (/) of the zip file.

@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

This task uploads the CFN-Sphere template 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

NOTE: This task is available for Python 2.7 and up.
