Last week, we spent some time talking to Gergely Orosz about our thoughts on what happens when an incident is over, and you're looking back on how things went. If you haven't read it already, grab a coffee, get comfortable, and read Gergely's full post Postmortem Best Practices here. But before you do that, here's some bonus material on some of our points.
The Docker images we provide for both Icinga 2 and Icinga Web 2 already contain quite a number of modules. For example, the Icinga Web 2 image contains all the Web modules developed by us. But one of the main benefits of Icinga is extensibility, so you might want to use more than what is already included. This might be some third-party module or a custom in-house module.
