When I joined to Olindata as a junior MySQL DBA I only had a vague idea about how Puppet, this open-source configuration management tool works in reality. I never really worked with a system like that, so I have been asked if I can learn it with Puppet Learning VM, which you can download from the following link here. This post is about how to set it up and what challenges you might encounter in this journey.
If you're doing a lot of command line work with icinga configurations and you happen to use vim a lot, it is super useful to use the vim syntax highlighting that comes with icinga2. Here's how to set it up on a CentOS/RHEL 7 box.
We're excited to release OpsTheater 1.6 and with that release make the full code open source. We actually quietly released a few weeks back already, but life is busy and I didn't have time to write this blog post until today.
It has been a while since my last blog post and I apologise as I've been really busy. However, in this blog, I would like to let everyone know that OlinData is a partner of Netways, the company behind Icinga2 and we are actively working on products/services related to it. Icinga2 is a fork of Nagios which have undergone numerous improvements, changes that it is now a product of its own.
Here I will be showing you why Icinga2, one of the many Nagios forks captivated me in terms or configurations.
Conferences are some of the greatest ways to connect with your peers and to soak up new knowledge. However, great conferences are not easy to find. Especially not Open Source-focused conferences. Well, I have good news today: the great RootConf conference iscoming up this week in Bangalore, and you can come and meet the OlinData India team and myself there!
Running a company that is focused on open source software is not easy. From an ideological perspective, the question of wether or not something you create should be open sourced is very clear: always YES (in caps even!), unless you have a _really_ good reason not to. However, there's always also the aspect of running a business: someone needs to pay the bills at the end of the month. The temptation to pay those bills with a proprietary product is big. With OlinData, that struggle is no different.
Today we are releasing version 1.4.0 of our new OpsTheater product. This is the first 'official' release that actually follows our release process. As such, we're still trying to determine how and what we want to do with actual releases. Stay with us if there are some things that can be improved.
Ansible is an open source, powerful automation software for configuring, managing and deploying software applications on the nodes without any downtime just by using SSH. Unlike other alternatives, Ansible is installed on a single host, which can even be your local machine, and uses SSH to communicate with each remote host. This allows it to be incredibly fast at configuring new servers, as there are no prerequisite packages to be installed on each new server.
