Motivation

----------

- Read our blog post, `"The curse of dead Lambda functions" `__.

- Enumerate list of Lambda functions from **every region**.

- Detect **"dead"** or unused Lambda functions.

Setup

-----

.. code-block:: bash

    git clone https://github.com/epsagon/list-lambdas

    cd list-lambdas/

    pip install -r requirements.txt

    python list_lambdas.py

Docker

-----

.. code-block:: bash

    git clone https://github.com/epsagon/list-lambdas

    cd list-lambdas/

    docker build -t list_lambdas:latest .

    docker run --rm -v $HOME/.aws:/root/.aws -t list_lambdas:latest --profile myprofile

CLI:

CSV file:

Usage

-----

Filter only Lambda functions that have not been active in the last 10 days:

.. code-block:: bash

    python list_lambdas.py --inactive-days-filter 10

Print extended information to the screen (same as in the CSV file):

.. code-block:: bash

    python list_lambdas.py --all

Sort by a chosen column (e.g. by last invocation time):

.. code-block:: bash

    python list_lambdas.py --sort-by last-invocation

Output table (**with extra data**) to a CSV file:

.. code-block:: bash

    python list_lambdas.py --csv lambdas.csv

Provide credentials:

.. code-block:: bash

    python list_lambdas.py --token-key-id  --token-secret
