You can pass other arguments to docker build by adding them to the second argument of the build() method. When passing arguments this way, the last value in the that string must be the path to the docker file.

This example overrides the default Dockerfile by passing the -f flag:

node {
    checkout scm
    def dockerfile = 'Dockerfile.test'
    def customImage = docker.build("my-image:${env.BUILD_ID}", "-f ${dockerfile} ./dockerfiles") 
}

This code snippet builds my-image: ${env.BUILD_ID} from the Dockerfile found at ./dockerfiles/Dockerfile.test.
