All Containers

FlexNet Manager Suite 2020 R2 (On-Premises)

A Docker container image is a package of all the scripts, software, runtime, system tools, libraries, and configuration required to run an application. A container image can be launched as a Docker container in a lightweight isolated environment using the Docker Engine. Like virtual machines, containers isolate resources. However, while virtual machines abstract hardware and run individual kernels, containers abstract the operating system in a single namespaced kernel. Therefore, containers eliminate the weight of a hypervisor by executing directly on the Linux or Windows kernel. The concept of containerization is not new with Linux, as AIX Workload Partitions (wPAR) and Solaris Zones have come before. However, Docker has provided a far more complete ecosystem.

The FlexNet inventory agent now has a new Linux component: Flexera’s Docker tracker. It is responsible for monitoring the Docker Engine to discover containers as they start and stop. Further to this, it is responsible for gathering raw evidence from container images. The Docker tracker waits for a container executing the image to be launched and performs a zero-footprint inventory on the executing container. This enables the full capability of the FlexNet inventory agent to be used to gather all types of raw installation evidence for each container image.

This page displays the following columns (listed alphabetically). Some columns are displayed by default and others can be displayed through the column chooser. To manage columns and other UI options, see the topics under Managing Columns in a Table.

Container host

The name of the device running the Docker service. You can click on the container host link to open it's Inventory Device Properties page.

Container ID

Unique identifier of the container.

Container name

The name of the container, only when the current item in the tree is Type = Container

Image ID

Unique identifier of the image. Populated for the image and it's containers. You can click on this link to open the Container Image Properties page for this image.

Last used date

The Last used date is only displayed when the Type is Image or Container.

Image:

• For an image with any containers with the Status = Running, the Last used date shows the most recent date that a reconcile occurred, when any container was running
• For an image when no containers have the Status = Running, the Last used date displays the last date reported by the most recent running container; displaying its Stopped date.

Container:

• When the container's Status is Running, the current date is displayed.
• When the container's Status is anything other than Running, it will display the Stopped date.

Name

The name of the hosts, images and containers, displayed as a hierarchy tree. Information in the tree can be expanded or contracted by clicking on the + or - controls next to each name.

Operating system

The operating system of the corresponding host. The source of this information varies accordingly:

• Container Host this will be the value of the Operating system on the Hardware tab of the host's Inventory Device Properties page
• For both Image and Container this will be the value as the Operating system on the Hardware tab of the Container Image Properties page.

Path

The path represents the summary of the container hierarchy in the form of host / image / container.

Repository tags

The Repository tags of this container or image. It is only populated when the Type is:

• Image displays any repository tags associated with this image
• Container then this will be the repository tag for the image used to launch this image.

Status

Displays the last reported status for a Docker. May be any one of these Docker values:

• Created
• Dead
• Exited
• Paused
• Restarting
• Removing
• Running
