SecurityContext holds security configuration that will be applied to a container. Some fields are present in both SecurityContext and PodSecurityContext. When both are set, the values in SecurityContext take precedence. FieldDescription allowPrivilegeEscalationboolean AllowPrivilegeEscalation controls whether a process can gain more privileges than its parent process. This bool directly controls if the no_new_privs flag will be set on the container process. AllowPrivilegeEscalation is true always when the container is: 1) run as Privileged 2) has CAP_SYS_ADMIN Note that this field cannot be set when spec.os.name is windows. appArmorProfileAppArmorProfile appArmorProfile is the AppArmor options to use by this container. If set, this profile overrides the pod's appArmorProfile. Note that this field cannot be set when spec.os.name is windows. capabilitiesCapabilities The capabilities to add/drop when running containers. Defaults to the default set of capabilities granted by the container runtime. Note that this field cannot be set when spec.os.name is windows. privilegedboolean Run container in privileged mode. Processes in privileged containers are essentially equivalent to root on the host. Defaults to false. Note that this field cannot be set when spec.os.name is windows. procMountstring procMount denotes the type of proc mount to use for the containers. The default value is Default which uses the container runtime defaults for readonly paths and masked paths. Note that this field cannot be set when spec.os.name is windows.Possible enum values: - "Default" uses the container runtime defaults for readonly and masked paths for /proc. Most container runtimes mask certain paths in /proc to avoid accidental security exposure of special devices or information. - "Unmasked" bypasses the default masking behavior of the container runtime and ensures the newly created /proc the container stays in tact with no modifications. readOnlyRootFilesystemboolean Whether this container has a read-only root filesystem. Default is false. Note that this field cannot be set when spec.os.name is windows. runAsGroupinteger The GID to run the entrypoint of the container process. Uses runtime default if unset. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. … Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
