Add variable to dockerfile{} section in Jenkinsfile to enable docker_buildkit

Question

This is snipshet of my code:

   stage('tf run') {
  agent {
    dockerfile {
      additionalBuildArgs "${ADDITIONAL_BUILD_ARGS}"
      registryCredentialsId "${REGISTRY_CREDENTIALS}"
      registryUrl "${REGISTRY_URL}"
      reuseNode true
    }
  }

Now I want do add special variable DOCKER_BUILDKIT=1 when I run this peace of code. For example in a shell it should look like: "DOCKER_BUILDKIT=1 docker build ." I need it because I want to run my docker in docker_buildkit mode. How can I do this?

Answer 1

environment {
    DOCKER_BUILDKIT='1'
}

Putting it in as an env variable in your pipeline will work
