Method Details

resolve

public static ContainerUserResolver.ContainerUser resolve(ContainerRuntimeUtil.ContainerRuntime runtime,
 String image)

Returns the ContainerUserResolver.ContainerUser (uid, gid) for the default user of the given image, or null if detection failed (e.g. the id command is not available). Successful resolutions are cached for the lifetime of the JVM; failures are not cached so callers can retry after transient errors (e.g. network issues while pulling the image).
