<p>I am want to deploy a Laravel application on AWS EKS.</p>

<p>My application uses Laravel Jobs and Queues. We can use the artisan utility which comes with the Laravel to manage the Queue Worker.</p>

<pre><code>php artisan queue:work
php artisan queue:restart
</code></pre>

<p>I will be using <a href="http://supervisord.org/index.html" rel="nofollow noreferrer">Supervisord</a> to monitor the queue process. </p>

<pre><code>[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /home/forge/app.com/artisan queue:work sqs --sleep=3 --tries=3
autostart=true
autorestart=true
user=forge
numprocs=8
redirect_stderr=true
stdout_logfile=/home/forge/app.com/worker.log
</code></pre>

<p>To start the queue when the container is deployed, I am using the ENTRYPOINT script in Dockerfile.</p>

<pre><code>#!/usr/bin/env bash

##
# Ensure /.composer exists and is writable
#
if [ ! -d /.composer ]; then
    mkdir /.composer
fi

chmod -R ugo+rw /.composer

##
# Run a command or start supervisord
#
if [ $# -gt 0 ];then
    # If we passed a command, run it
    exec "$@"
else
    # Otherwise start supervisord
    /usr/bin/supervisord
fi
</code></pre>

<p>What I am not able to understand is that if I have multiple replicas of my application running, how will I remotely stop and start the queue process on my running containers.</p>

<p>On EC2, I can use AWS SSM to run shell commands on multiple instances at the same time.</p>

<p>Is there something similar available to AWS EKS also?</p>

<p>Or in general, how do you manage the queue process running on multiple containers in AWS EKS?</p>

<p>In general, if you want to execute a command in multiple containers at once, you can do this, for example, with:</p>

<pre><code>for pod in $(kubectl get pods -o jsonpath='{.items[*].metadata.name}' -l app=myapp); do
  kubectl exec "$pod" mycommand
done
</code></pre>

<p>This executes <code>mycommand</code> in the first container of all Pods with the <code>app=myapp</code> label. It doesn't matter if your cluster runs on EKS or anywhere else.</p>
