|

Some other condcerns have been brought up that we should keep in mind. One is that long running containers (> 2 Weeks) may become stale and need a restart. It is unclear whether this is an Icinga issue or something else.
|
||||
|
||||
Another concern is that networking can be a challenge when separating services into separate containers.
|
||||
|
||||
### Development
|
||||
For easier development and changes of earlier stages the containers will contain lots of `RUN` blocks which is very "not best-practice" in Docker. This will be changed before the first release.
|
||||
|
||||
### Influences
|
||||
There are many Docker containers for Icinga 2 out in the wild. Most were built to serve a special purpose and might not be fit for what this project is aiming for. Nonetheless the first commits rely heavily on the work of following users:
|
||||
* [lazyfrosch](https://github.com/lazyfrosch/docker-icinga2)
|
||||
* [bodsch](https://github.com/bodsch/docker-icinga2)
