Python Boto3 Task

This Tekton Task defines a reusable Task named python-boto3 for running Python scripts that use the boto3 library to interact with AWS services.

Parameters

The Task accepts the following parameters:

• aws-region (optional, default: us-east-1): The AWS region to use for the boto3 client.

Volumes

The Task expects a ConfigMap named python-script-configmap to be mounted as a volume named python-script. This ConfigMap should contain the Python script to be executed, with the key script.py.

Steps

The Task consists of a single step that runs the Python script using the python:3.9 image. The step performs the following actions:

1. Installs the boto3 library using pip.
2. Sets the AWS credentials as environment variables (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) from a Kubernetes Secret named aws-credentials.
3. Sets the AWS region as an environment variable (AWS_DEFAULT_REGION) using the value provided in the aws-region parameter.
4. Mounts the python-script volume containing the Python script at /workspace/python-script.
5. Executes the Python script located at /workspace/python-script/script.py.

Usage

To use this Task, you'll need to create the following resources:

1. A Kubernetes Secret named aws-credentials with your AWS Access Key ID and Secret Access Key.
2. A ConfigMap named python-script-configmap with your Python script (script.py).

Python script named script.py with the following content:

#####################################################

script.py - begin

##################################################### import boto3

Your Python script that uses boto3 goes here

For example:

s3 = boto3.client('s3') response = s3.list_buckets()

print(response)

###################################################

script.py - end

################################################### To create the ConfigMap, you can use the kubectl create configmap command and specify the --from-file flag to include the Python script file:

command to create configmap

kubectl create configmap python-script-configmap --from-file=script.py This command will create a ConfigMap named python-script-configmap with the contents of the script.py file. Alternatively you can also use config-map.yaml given in sample

Then, you can create a Tekton TaskRun that references this Task and provide the necessary parameters (if any).
