Running Home Assistant on Kubernetes. It is about time to put your IoT devices under control. Everything runs off the cloud on my on-premise Kubernetes. Clean and secure.
This blog will not cover what Home Assistant is or how Kubernetes works. I assume you already have that covered.
A simplified guide to logging Docker to Elasticsearch. Although there are many tutorials about how to ship Containers logs to Elasticsearch, this one is different from all as it uses syslog-ng. It also works with Podman!
Update: I moved the chapters about parsing and visualizing NGINX / Apache access logs in Kibana into a dedicated post / github repo.
Update 2: This post has been refactored and simplified to be compatible with Elasticsearch ECS and make it easier to implement. Compatible with Elasticsearch 7.x.
Update 3 (2020): Add support both for Docker and Podman. Improved readability. Continue reading Simplified guide to logging Containers to Elasticsearch in 2020 (with syslog-ng)
In the last post I wrote about how you can create a central syslog server. This time I will show you how you can use syslog-ng to parse fail2ban log messages, enrich it with GeoIP metadata and send into Elasticsearch. You can even visualizing Fail2ban logs in Kibana to see where the failed login attempts are coming from.
Update: This post has been reviewed and all Fail2ban and GeoIP related contents have been merged here from the previous post. Look no further, you will find everything you need here. Note that this guide requires Elasticsearch 7.x.
Your home network might already contain some devices or systems like a home server, a WiFi router, a media player, or home automation system. It is a best practice creating a central syslog server and storing logs of various sources in one place.
Update: The fail2ban and GeoIP related contents have been merged into post visualizing Fail2ban logs in Kibana.
This post will cover the basics. Creating a central log server and receiving logs from an OpenWRT device. Please note that you can do many more. See the other posts I created in this subject.
I already had plans to write about Docker. However a recent system update caused issues and Docker failed to restart. This service outage made me think and write about such a typical maintenance task.
I know that I created the issue at the first place. However I could fix it and I will show you how I did it and how can I avoid that in the future.
When I created a central file sever, I mentioned that some of the problems with the solution are yet to be resolved.
Lucky for us, mounting NFS exports by using autofs service help us and gives the following advantages too. Continue reading Mounting NFS exports by using autofs
