SecurityContext
SecurityContext is a Kubernetes object that defines privilege and access control settings for a Pod or Container. It allows administrators to specify security-related options for a workload, ensuring that it runs with the intended security posture.
There are two main levels at which SecurityContext can be applied: Pod level and Container level. When
Key security features that can be configured using SecurityContext include:
* runAsUser and runAsGroup: Specifies the user and group ID under which the container's processes will run.
* fsGroup: Sets a supplementary group ID for the volume that is mounted into the Pod. This
* allowPrivilegeEscalation: Determines whether a process can gain more privileges than its parent process. It's recommended to
* capabilities: Allows for fine-grained control over Linux capabilities, such as adding or dropping specific capabilities. This
* seccompProfile: Applies a Seccomp (Secure Computing Mode) profile to restrict the system calls a container can
* privileged: When set to true, the container runs in privileged mode, bypassing many security restrictions. This
* readOnlyRootFilesystem: Enforces that the container's root filesystem is mounted as read-only.
By utilizing SecurityContext, Kubernetes users can significantly enhance the security of their containerized applications, aligning with
