⁠Issues

Before reporting your issue please try updating Docker to the latest version and check if it resolves the issue. Refer to the Docker installation guide⁠ for instructions.

SELinux users should try disabling SELinux using the command setenforce 0 to see if it resolves the issue.

⁠Getting started

⁠Installation

Automated builds of the image are available on Dockerhub⁠ and is the recommended method of installation.

docker pull nlmacamp/check_mk:1.4.0p15    (or nlmacamp/check_mk:latest)

Alternatively you can build the image yourself.

docker build -t nlmacamp/check_mk github.com/viper0131/check_mk

⁠Quickstart

Start Check_MK using:

    docker run -itd --name check_mk \
           --publish 80:5000 \
           --restart always \
           nlmacamp/check_mk

OPTIONAL: Specify outgoing mail server with -e "MAILHUB=<IP:PORT>"

If your want to keep your configuration files + performance data persistent, you have to map the /opt/omd directory to the local filesystem like this:

  --volume <localdir>:/opt/omd

Additional volumes could be mapped for the check_mk backup feature or check scripts.

docker exec -it check_mk omd status
