Using LamZip

Initial Project Setup

Create a defaults file in your project directory to simplify packaging:

lamzip make-config [--config-name .altname]

Just using lamzip make-config without any arguments will create the default config file .lamzip.yaml. Contained in the default config is an example setup that looks like the following:

# Lambda-Zip (lamzip)
#
# Defaults for packaging your AWS Lambda function
#

source-directory: ./appsrc
destination-directory: ./dist
package-prefix: foo
package-version: 0.0.1

Configure LamZip

Your project structure should look something like the following:

Main-Project-Folder\
   dist\
   appsrc\
      lib1\
      lib2\
      app.py
   .bumpversion
   .lamzip.yaml
   .gitignore
   LICENSE
   README
   requirements.txt
   setup.py

In this example you would use the following settings:
source-directory to ./appsrc
destination-directory to ./dist # the default is typically the case here
package-prefix to app # zip file package name pre-pended to the version
package-version to 0.0.1 # current app version

Run LamZip (Package your function)

Once configured, you can just run LamZip in the following way:

# lamzip use-config

LamZip using existing config file: .lamzip.yaml
  Source Dir: ./appsrc
  Destination Dir: ./dist
  Package Prefix: app
  Package Version: 0.0.1

Creating Archive: ./dist\app-0.0.1.zip
  adding: ./appsrc\app.py

Pass all parameters using CLI

It is not required to use the LamZip config file. All arguments can be passed using the CLI in the following way:

lamzip specify --src-dir ./appsrc --dest-dir ./dist --zip-prefix app --zip-version 0.0.1

Integration

Now that you have the LamZip config deployed to your project folder it is recommended to use a versioning utility like "Bumpversion" to easily maintain the version configuration within the LamZip config file (.lamzip.yaml).

Important

Ensure the python "Scripts" directory is located in your system path, as this library installs LamZip to that location for global use.

Verify the path:
Use the version response to verify the interpreter location on your system.

# pip3 -V

pip 20.0.2 from c:\program files\python37\lib\site-packages\pip (python 3.7)

Using BASH: "echo $PATH" to verify "<path-to-python-base>/scripts" exists
Using PowerShell: "$ENV:$PATH" to verify "<path-to-python-base>\Scripts" exists
