I am using Build Toolkit to build docker image for each microservice.

./build.sh

export DOCKER_BUILDKIT=1
# ....
docker build -t ....
# ... 

This works on my machine with docker (18.09.2).

However, it does not work with Jenkins, that I setup as following :

• EKS is provisioned with a Terraform module

  module "eks" {
    source   = "terraform-aws-modules/eks/aws"
    version  = "5.0.0"
    # ....
  }
  

• Jenkins is deployed on EKS (v1.12.10-eks-ffbd9 , docker://18.6.1) via this Helm Chart.

• Jenkins plugins as defined in Values of the helm release:

  • kubernetes:1.18.1
  • workflow-job:2.33
  • workflow-aggregator:2.6
  • credentials-binding:1.19
  • git:3.11.0
  • blueocean:1.19.0
  • bitbucket-oauth:0.9

• Jenkins Pipeline is declarative, and it uses a Pod template where the container image is docker:18-dind and the container name is dind.

• This is my Jenkinsfile

  pipeline {
    agent {
      kubernetes {
        defaultContainer 'jnlp'
        yamlFile 'jenkins-pod.yaml'
      }
    }
    stages {
      stage('Build Backends') {
        steps {
          container('dind') {
            sh 'chmod +x *sh'
            sh './build.sh -t=dev'
          }
          containerLog 'dind'
        }
      }
    }
  

  }

When Jenkins executes this pipeline, it shows this error :

buildkit not supported by daemon

I am not sure which software should I upgrade to make docker-buildkit work ? and to which version ?

• Terraform eks Module which is now 5.0.0 ?

Or

• docker:18-dind image which behaves like environment of the ephemeral Jenkins slaves ?

Or

• the Jenkins Plugin kubernetes:1.18.1 ?
