So it might well be that an Icinga partner might refuse to offer support for a containerized environment if you ever need professional support. In order to make this happen with Icinga, there are some architectural changes required which may or may not happen in the future. Note how the container ID changes as you transition from the container running Docker, to the innermost container! Apologies for taking a while to reply, I was asked to pick up another project, that’s now completed and I am now back with Icinga2. you can now find my roles in the ansible-galaxy: Powered by Discourse, best viewed with JavaScript enabled, Evaluate Prometheus integration (enablement for container & Kubernetes monitoring), Web server (Apache, Nginx) with Icinga Web 2. This generally works fine when you’re doing innocuous things like checking free disk space or if a certain process is running. - ./${FIRSTNAME}-container/etc/pnp4nagios:/etc/pnp4nagios links: One will be able to seek an integration with the “classic” way of monitoring objects with Icinga, but that’s not an easy task on its own. What advantages does it bring for Icinga? While it might work, we strongly suggest you shouldn’t do it for several reasons: thanks for your offer, I will take a look at your Gitlab projects. You can disable the automatic kickstart when the container starts by setting the DIRECTOR_KICKSTART variable to false. - sql the Director installation should be persistent. hostname: ${FIRSTNAME}-web-pnp By default, icinga tries to perfom a ssh service check on all hosts running linux.

Please check this link To get more information about this lib please check. - sql Latest version is v1.0.1 released on 2020-02-27. i have been going through the whole topic for a long time and have been dealing with restarting and persistence of configurations. - ./${FIRSTNAME}-container/mibs:/mibs With leveraging this into a distributed monitoring cluster, a Docker container for the Icinga 2 agent makes sense as a sidecar e.g. - ./${FIRSTNAME}-container/cache/icinga2:/var/cache/icinga2 About; Puppet; Ansible; Search for: PUPPET, DOCKER, ICINGA AND AWS AUTOMATION – DEPLOYING INSTANCES, CONTAINERS AND MONITORING. - ./${FIRSTNAME}-container/perfdata:/var/lib/pnp4nagios/perfdata Of course, follow the documentation like in a normal installation but execute it inside the container. How is the container icinga-core started? env_file: ./secrets.env The Icinga check for "configured eth" ends up in a warning: Mostly common is to use reliable and reproducible test environments, put into containers and container clusters (example: GitLab CI). Actions. Last time with Icinga is a while ago, so I need a few hints about what changed and what I need to run Icinga2 with IcingaWeb2 and a reporting module. This build is automated by push for the git-repo. - core Pulled the image named jordan/icinga2:latest, did the necessary mounts and env. context: ./snmptrap Here is a Dockerfile I have written which we are using in production - happy to hear if anyone has any suggestions as I am relatively new to Docker - it runs nginx, php and supervisor acts as a process manager. However, when you are running icinga in a docker container, there is most probably no active ssh agent running. volumes_from: After roughly 8 hours, Icinga will consume all available memory and swap on my 16 GB system until it crashes completely. After long time … This saves both a lot of disk space and a lot of time, and I think this makes a huge difference when running e.g. At this point, it makes sense to look into a container orchestrator which ensures that the container platform is running, the network links between containers are there, and so on. Also I am currently creating ansible roles for icinga2 and icingaweb2.
