Devops Week News — Issue #51
Starting this edition, we bring you a video on auto-scaling Docker Swarm services using instrumented metrics with Prometheus.
On Security Advisor section, PostgreSQL gets a fix for a passwordless authentication Flaw.
On article side, revisit ansible.cfg to speed up Ansible execution of playbooks; Linux load averages explained, including why they include the uninterruptible I/O sleep state; things that everyone forgets before committing code and how to monitor a Traefik reverse proxy with Prometheus.
Please, send us links, events, comic strip, DevOps job-related, etc., via @devopsweeknews.
Video of the week
Viktor Farcic presents an auto-scaling solution to services running on the Docker Swarm cluster. He assembles a puzzle with few open source projects to achieve it. Check it and learn more.
Newly released versions of the PostgreSQL object-relational database system fix three security vulnerabilities and over 50 other bugs. Two of the flaws could allow attackers to access accounts and information.
This post will remember you to verify your ansible.cfg precedence and add the config pipelining to speed up Ansible execution.
What an article! It will explain Linux load averages, including why they include the uninterruptible I/O sleep state.
Are you ready for committing your changes? This is the kind of article which is good to read time-to-time to do not forget the principles and practices when it comes to committing code, such as old comments, and how to work around them.
In this tutorial, you will learn how to use Docker to setup Traefik with Prometheus and view all of Traefik’s metrics from a Prometheus Dashboard.
