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

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):

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:

nicc777

#!/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
