Flexera Container Monitor

The Flexera Container Monitor reports on all containers and images running on the host machine. It is designed for use outside Kubernetes clusters, particularly on immutable operating system platforms such as Flatcar Container Linux or Red Hat Enterprise Linux CoreOS.

The monitor uses Docker Compose to:

• Mount /etc/os-release and /etc/hostname as read-only to capture host details
• Map /var/run/docker.sock to scan running containers and identify images

To download and install the Flexera Container Monitor:

1. Go to the Inventory Settings page (Data Collection > IT Assets Inventory Tasks > Inventory Settings).

The Inventory Settings page displays.

2. Go to the Inventory agent for download section to see the Download Flexera Kubernetes inventory agent link.
3. Click Download Flexera Kubernetes inventory agent and save the downloaded archive file to a suitable location.
4. From the downloaded archive, extract the Flexera Kubernetes inventory agent image and then navigate to the extracted directory, for example with the following command line (replacing the placeholder x.y.z with the appropriate version numbers):

tar xzf flexera-krm-operator-x.y.z.tar.gz

cd flexera-krm-operator-x.y.z

5. Navigate into the |-> containermonitor-a.b.c directory (where a.b.c represents the version number).
6. Follow the instructions in the readme.txt file in this directory.
