Expand...

The container should drop all default capabilities and add only those that are needed for its execution.

Container 'RELEASE-NAME-node-red' of Deployment 'RELEASE-NAME-node-red' should add 'ALL' to 'securityContext.capabilities.drop'

Expand...

'runAsNonRoot' forces the running image to run as a non-root user to ensure least privileges.

Container 'autopermissions' of Deployment 'RELEASE-NAME-node-red' should set 'securityContext.runAsNonRoot' to true

| | Kubernetes Security Check | KSV013 | Image tag ':latest' used | LOW |

Expand...

It is best to avoid using the ':latest' image tag when deploying containers in production. Doing so makes it hard to track which version of the image is running, and hard to roll back the version.

Container 'RELEASE-NAME-node-red' of Deployment 'RELEASE-NAME-node-red' should specify an image tag

| | Kubernetes Security Check | KSV014 | Root file system is not read-only | LOW |

Expand...

An immutable root file system prevents applications from writing to their local disk. This can limit intrusions, as attackers will not be able to tamper with the file system or write foreign executables to disk.

Container 'autopermissions' of Deployment 'RELEASE-NAME-node-red' should set 'securityContext.readOnlyRootFilesystem' to true

Expand...

A program inside the container can bypass Seccomp protection policies.

Container 'RELEASE-NAME-node-red' of Deployment 'RELEASE-NAME-node-red' should specify a seccomp profile
