Release 1.33.0

June 19, 2024 

Qualys strongly recommends upgrading your Qualys Container Security Sensor to 1.33.0 version. 

What's New?

Support to 'Overlay' Storage Driver on 'containerd' runtime 

CS Sensor saves the image and creates a .tar output. This operation can be time-consuming if the image size is large. If you have a 'containerd' runtime installed, and your image is pulled locally, you can avoid image saving with the help of runtime's underlying overlay2fs filesystem. The 'Overlay' storage driver is supported by these sensors - General, CI/CD, and Registry. To know how to enable the storage driver, refer to CS Sensor 1.33 Deployment Guide.

In case you do not want to use the Storage Driver, you can still install the CS Sensor, but with General and CI/CD sensors; 'static', 'sca', 'static', 'secret', 'malware' scans may not work.
However, all types of scans work with Registry Sensor without the 'Overlay' Storage Driver. 

Currently, CS Sensor supports 'Overlay' storage driver only with 'containerd' runtime.

Update in Sensor Launch

Earlier, Qualys namespace was getting created automatically while launching CS Sensor using 'kubectl create -f <CS Sensor Deployment File>.yml' command. With this release, you need to create the 'qualys' namespace manually before launching CS Sensor. To know how to create and delete the namespace, refer to to CS Sensor 1.33 Deployment Guide.

You must provide the namespace name as 'qualys'. Any modification in the name of the namespace is strictly not allowed.

Helm Chart 1.12.0 Updates

The Qualys Container Security package consists of the 'values.yaml' file which deploys the sensor in various environments. This section explains the updates in the latest Helm chart (values.yaml) file. 


To support the 'Overlay' feature, 'storageDriverPath', 'enableStorageDriver', and 'storageDriverType' flags are introduced and the 'socketPath' flag is updated in the 'values.yaml' file. With this release, the following flags are introduced or updated in the 'values.yaml' file.
