I am trying to configure Jenkins as docker container with docker-in-docker on an EC2 instance running Ubuntu 22.04 but I am getting `GLIBC_2.32' and 'GLIBC_2.34' not found when I try to run a script containing docker command using docker plugin in Jenkins. I have followed this as reference for setting Jenkins on my localhost. When moved to remote, I get these errors

...
$ docker login -u username -p ******** https://registry.gitlab.com
docker: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by docker)
docker: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by docker)
...

Here is the docker-compose.yaml file

version: '3.3'

services:
  docker-in-docker-container:
    image: docker:dind
    container_name: docker-in-docker-container
    user: root
    privileged: true
    expose:
      - 2375
    volumes:
      - ./data:/var/jenkins_home
    environment:
      DOCKER_TLS_CERTDIR: ""
    restart: on-failure

  jenkins-container: 
    image: jenkins/jenkins:lts-jdk17
    container_name: jenkins-container
    user: root
    depends_on:
      - docker-in-docker-container
    ports:
      - '8080:8080'
    privileged: true
    volumes:
      - ./data:/var/jenkins_home
      - /usr/bin/docker:/usr/bin/docker
    environment:
      DOCKER_HOST: tcp://docker-in-docker-container:2375
    restart: on-failure

I tried to use various images from the Jenkins docker repository like alpine, jdk8, jdk11, and jdk17, but no luck.

Here is ldd info for troubleshooting from host machine

Looking forward to any help! Thanks.

As you're suspecting, you've having shared-library issues because you're injecting a docker binary that depends on a different version of GNU libc than exists in the image.

Injecting a docker binary like this isn't especially reliable due to issues like this. In theory you could work around it by building a custom image that installed the required versions of the shared libraries, but if you're doing that, it's easier and safer to install the docker CLI tool in the image. (Running the Docker daemon has complex requirements, but the CLI tool itself doesn't depend on anything other than access to a Docker socket.) Also see the "Installing more tools" section in the Jenkins image documentation.

FROM jenkins/jenkins:lts-jdk17
USER root
RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive \
    apt-get install --no-install-recommends --assume-yes \
      docker.io
USER jenkins

You do not need EXPOSE, CMD, or other setup; that all comes from the base image.

In the Compose file, add a build: line to build this custom image, delete the image: line, and delete the volumes: mounting the host's /usr/bin/docker.

version: '3.8'
services:
  jenkins-container:
    build: .
    # no image:
    volumes:
      - ./data:/var/jenkins_home
      # but not /usr/bin/docker
