Functions

func CheckDockerAccessible

func CheckDockerAccessible() bool

CheckDockerAccessible verifies that the Docker daemon is accessible.

func CheckLogDirMounted

func CheckLogDirMounted(containerID, logDir string) bool

CheckLogDirMounted uses docker inspect to verify the log directory is mounted.

func CheckPortMapping

func CheckPortMapping(containerID, port string) (bool, error)

CheckPortMapping uses docker inspect to verify that the specified port is mapped.

func CheckStdinInteractive

func CheckStdinInteractive(containerID string) bool

CheckStdinInteractive uses docker inspect to verify the container was started with -i flag.

func DetectContainerID

func DetectContainerID() (bool, string)

DetectContainerID detects if the current process is running inside a container and attempts to extract the container ID from cgroup entries. It returns (isContainer, containerID). The containerID may be empty even when a container is detected (e.g., via /.dockerenv or environment variable).

func IsRunningInContainer

func IsRunningInContainer() bool

IsRunningInContainer detects if the current process is running inside a container.

func ValidateContainerID

func ValidateContainerID(containerID string) error

ValidateContainerID validates that the container ID is safe to use in commands. Container IDs should only contain lowercase hex characters (a-f, 0-9).
