I only have to download the tar file? links: - core volumes_from: Grafana Loki. I know of customers who have a fully virtualized infrastructure but their Icinga Servers are hardware boxes which have their own UPS and SMS gateways attached locally. Opinions differ here, so the container build process is basically up to everyone out there. # object for icinga2satellite. However, using the Docker “logs” command is a little primitive, as every time you run docker logs container_id you get all the logs of that process from the beginning. - ./${FIRSTNAME}-container/perfdata:/var/lib/pnp4nagios/perfdata Now that you’ve set up your development environment, thanks to Docker Desktop,you can begin to develop containerized applications. Nginx, PHP and Icinga Web inside. the Director installation should be persistent. - ./${FIRSTNAME}-container/log/icinga2:/var/log/icinga2 While developing Docker images for Icinga 2, Icinga Web 2 and Icinga DB we stumbled over OpenShift which doesn’t allow images to run as root by default. Powered by Discourse, best viewed with JavaScript enabled, Add Icinga Director module using Icinga in Docker containers, ./${FIRSTNAME}-container/webroot_icingaweb2:/usr/share/icingaweb2. If you e.g. - ./${FIRSTNAME}-container/etc/pnp4nagios:/etc/pnp4nagios There can be so many things be changed that it’s near to impossible to offer support for such a setup. - ./${FIRSTNAME}-container/etc/icingaweb2:/etc/icingaweb2 If you are interested, want to join in or maybe shake your head: What’s special in my dind image? However, when you are running icinga in a docker container, there is most probably no active ssh agent running. In order to prevent icinga always showing an error, insert pnp 1.1.0. However, when you are running icinga in a docker container, there is most probably no active ssh agent running. Menu. (Hope I got the container names right), I only have to download the tar file? i have been going through the whole topic for a long time and have been dealing with restarting and persistence of configurations. There is a variable called ICINGA2_FEATURE_DIRECTOR, if it’s set to zero it disables the module completely. In order to prevent icinga always showing an error, insert. The Icinga Director Icinga Web 2 module is installed and enabled by default. Thing is, containers are rather short lived. One has to enable that explicitly. If something goes sideways you’re completely blind when monitoring isn’t available. In this tutorial, we tried Firefox in our CentOS 7 Docker Image with Firefox installed. - core Please check out what members of the community shared on hub.docker.com. Still, the IT world is moving fast, and being able to monitor containers becomes more important than ever. - sql With leveraging this into a distributed monitoring cluster, a Docker container for the Icinga 2 agent makes sense as a sidecar e.g. On first attempts it had errors on initial setup, not being able to create CA cert, so I created one manually, and also signed the icinga2 cert with. At first, you need to have a running Docker on your system. endpoints = [ "icinga2satellite" ] parent = "icinga2masterserver". } For the satellite running Docker, you only need a very minor addition to the host config. ports: Maintaining and upgrading this installation will not be an easy task. in a container cluster such as Kubernetes.

My personal website dnsmichi.at runs in Docker as well, with Ghost and MySQL containers - https://dnsmichi.at/new-blog/. Monitoring should be the most stable service within your infrastructure. It is built with a regular Dockerfile. Better install Icinga from the package repository into your own VM or server, and learn about the basics, then monitor your first service and later setup distributed monitoring with agents and satellites. ports: env_file: ./secrets.env version: “2” domainname: ${DOMAINNAME} hostname: ${FIRSTNAME}-web-pnp How is the container icinga-core started? - ./${FIRSTNAME}-container/etc/icinga2:/etc/icinga2 Hi there! image: NAMEOFTHECOMPANY/icinga2-snmptrap One thing to keep in mind here - each application should be running in its own container, for Icinga this would be: Additional containers would add InfluxDB, Graphite, Elasticsearch, etc. - ./${FIRSTNAME}-container/contrib-plugins:/usr/lib/contrib-plugins context: ./web-pnp At the moment these work so far that I use them in a customer project. - ./${FIRSTNAME}-container/lib/php5/sessions:/var/lib/php5/sessions Installation & Usage: The current version don't need any arguments to be used all you need to do is: Install the Python3 library for the Docker Engine API: pip3 install docker. hostname: ${FIRSTNAME}-snmptrap It was originally created as a fork of the Nagios system monitoring application in 2009. icingaweb, no graphs. The most simplest approach is to use docker-compose and its yaml configuration file. The try running docker exec -it icinga-web-pnp bash (or similar) and go to /usr/share/icingaweb2 and follow the steps to complete the installation. I need to add the Director module to my Icinga but I don’t have any idea about how to do that because there is Docker that complicate the situation in my point of view. InfluxDB/Graphite writers via environment variable on-demand. Please check this link To get more information about this lib please check Icinga2 is a tool for monitoring the status and availability of various services running on remote hosts. The dockerhub-repository is located at https://hub.docker.com/r/jordan/icinga2/. No other things? volumes: I could create it manually - once Icinga Server was already up and running, but I decided to be little more challenging: What if automate this process using… AWS tech Just another AWS tech weblog. services: sql: If you have any questions, wishes or suggestions … always bring it to me! It is like pain It requires you to have at least Docker v1.6.0+ installed, then fire away and bind port 80 to your host’s port 3080: $ sudo docker run -ti -p 3080:80 icinga/icinga2 Navigate to http://localhost:3080/icingaweb2/ and login using icingaadmin/icinga as credentials.

I have to add them to some container? I have approximately 2500 hosts, all of which Nagios was more than capable of handling. Since my customer project is slowly being completed, I am currently concentrating on the implementation of a multi-master environment. - ./${FIRSTNAME}-container/etc/ssmtp:/etc/ssmtp PS: 5 years ago, I wasn’t convinced by the maturity of containers. Nowadays, they help me everyday e.g. GitLab.com In general, the development workflow looks like this: 1. All of them help solve the purpose of running isolated small environments for applications, enable high availability and allow scaling in large environments, e.g. Almost nothing! Let’s see what is in that Dockerfile. How is the monitored object configuration being deployed? Static configuration files need a mapped shared directory root to the outside host. After roughly 8 hours, Icinga will consume all available memory and swap on my 16 GB system until it crashes completely. Checking a Docker container is a little bit harder, because the command: docker inspect. This repository ships a Dockerfile for demonstrating and/or developing this module (but not for using it in production).. monitoring 2.6.2 Debian/Ubuntu: Proceed with the bundlergem installation for all systems (CentOS, Debian, etc.). - 80:80 build: Specifically, when running multiple instances of Docker side by side, it is possible to “seed” them with a shared set of images. Docker_check.py is a nagios compatible plugin to check docker containers stats.. Icinga is an open-source computer system and network monitoring application. Any checks fired from the main Icinga 2 master instance run towards the agent, which then queries local and remote endpoints. my recommendation: no monitoring stuffed into a container! web-pnp: The try running docker exec -it icinga-web-pnp bash (or similar) and go to /usr/share/icingaweb2 and follow the steps to complete the installation. 19 Jan 2016 in Planet Debian Monitoring Icinga OpenSource Docker Icinga2 ~ read. in a container cluster such as Kubernetes. links: Note how the container ID changes as you transition from the container running Docker, to the innermost container! ports: 2. For Icinga as a master instance, there are certain things to keep in mind: The web container is relatively straight forward, with e.g. To customize the kickstart settings, modify the /etc/icingaweb2/modules/director/kickstart.ini . File: /etc/icinga2/zones.d/icinga2masterserver/icinga2satellite.conf. Enables Prometheus-as-a-Service for large organizations running at scale. This repository contains the source for the icinga2 dockerimage. Provided those, together with keys to the appropriate directories. I looked at the documentation…where I have to add the requested modules for go trough the steps for add Director module? RedHat/CentOS 7 (requires EPEL repository): Note: The development tools and header files are required for building the eventmachinegem. - core Can you share the Dockerfiles? settings.
