The function is for a SAM template that looks something like the following:

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: Example Template for AWS HTTP API to Python Lambda Function

Parameters:
  StageNameParameter:
    Type: String

Assuming you have LOG_GROUP_NAME and STREAM_NAME as environment variables, you can run the following:

aws logs get-log-events --log-group-name "$LOG_GROUP_NAME" --log-stream-name "$STREAM_NAME" | yq -o=json | jq '.events[] | .timestamp, .message' > stream.log

The log entries with timestamp and message will now be in the file stream.log

Another way to format the output (prevent splitting lines for timestamp and message fields):

AWS / Boto3 Functions and Lambda Functions

Module header functions

Prerequisite funtion defined early in a module:

import boto3
import traceback
import os

Command:

pip3 install git+https://github.com/aws/aws-cli.git@v2

Use Case

These steps demonstrate how to get the JavaScript library for AWS Cognito integration when using simple HTML and JavaScript - no frameworks like ReactJS, or other Node type projects.

Prerequisites

Even though you may not want to use a framework, you still require a relatively new stable version of nodejs

My approach:

Prepare volumes

Also refer to the GitLab Documentation

docker volume create gitlab-data
docker volume create gitlab-logs
docker volume create gitlab-config

How to keep cluster connections cleanly separated

With time the .kube/config file will contain a mix of dev, test and prod cluster references. It is easy to forget switching off from a prod cluster context and make a mistake and run for example kubectl delete ns crossplane-system.

Direnv based setup

Use the following setup to avoid these kinds of errors and keep clusters separate.

	#!/bin/bash

	for node in node1 node2 node3 ;do
	multipass exec $node -- sudo DEBIAN_FRONTEND=noninteractive apt update
	multipass exec $node -- sudo DEBIAN_FRONTEND=noninteractive apt install -yq software-properties-common
	multipass exec $node -- sudo DEBIAN_FRONTEND=noninteractive add-apt-repository -y ppa:gluster/glusterfs-7
	multipass exec $node -- sudo DEBIAN_FRONTEND=noninteractive apt update
	multipass exec $node -- sudo DEBIAN_FRONTEND=noninteractive apt install -y glusterfs-client
	multipass exec $node -- sudo mkdir -p /opt/local-path-provisioner
	multipass exec $node -- sudo chmod 777 /opt/local-path-provisioner

	#!/bin/sh

	HF=/etc/hosts
	MP=/glusterfs-data

	echo "Updating /etc/hosts"
	IP1=$(multipass info glusterfs1 \| grep IPv4 \| awk '{print $2}')
	IP2=$(multipass info glusterfs2 \| grep IPv4 \| awk '{print $2}')
	sudo sed -i '/glusterfs1/d' $HF
	sudo sed -i '/glusterfs2/d' $HF

	import java.net.InetAddress;
	import java.net.UnknownHostException;

	void displayStuff(String whichHost, InetAddress inetAddress) {
	print("--------------------------" + "\n");
	print("Which Host:" + whichHost + "\n");
	print("Canonical Host Name:" + inetAddress.getCanonicalHostName() + "\n");
	print("Host Name:" + inetAddress.getHostName() + "\n");
	print("Host Address:" + inetAddress.getHostAddress() + "\n");
	}
