4- configure jenkins image to run docker commands on your host docker daemon
5- create CI/CD for this repo https://github.com/mahmoud254/jenkins_nodejs_example.git

New Questions part.

1- create docker file to build image for jenkins slave
2- create container from this image and configure ssh
3 from jenkins master create new node with the slave container
4- integrate slack with jenkins
5- send slack message when stage in your pipeline is successful
6- install audit logs plugin and test it
7- fork the following repo https://github.com/mahmoud254/Booster_CI_CD_Project and add dockerfile to run this django app and use github actions to build the docker image and push it to your dockerhub

4- configure jenkins image to run docker commands on your host docker daemon

Docker file.

```
FROM jenkins/jenkins:lts
USER root
RUN apt-get update -y

RUN apt-get install apt-transport-https curl gnupg-agent ca-certificates software-properties-common -y
RUN curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
RUN add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" -y
RUN apt-get update -y
RUN apt-get install docker-ce docker-ce-cli containerd.io -y

RUN usermod -aG docker jenkins

```

Build and push the image.

```
docker build -t amrtarek6/jenkins_main:version .
docker push amrtarek6/jenkins_main:version
```

Runing the container.

```
docker run -it -d --name jenkins_main -v /var/run/docker.sock:/var/run/docker.sock amrtarek6/jenkins_main:version
```

5- create CI/CD for this repo https://github.com/mahmoud254/jenkins_nodejs_example.git

pipeline Code.

```
    pipeline {
        agent any
        stages {
            stage('CI') {
                steps {
                    git 'https://github.com/mahmoud254/jenkins_nodejs_example'
                    withCredentials([usernamePassword(credentialsId: 'Dockerhub', usernameVariable: 'USER', passwordVariable: 'PASS')]) {
                        sh "docker build . -f dockerfile -t ${USER}/node-app:v1"
                        sh "docker login -u ${USER} -p ${PASS}"
                        sh "docker push ${USER}/node-app:v1"
                    }
                }
            }

            stage('CD') {
                steps {
                    withCredentials([usernamePassword(credentialsId: 'Dockerhub', usernameVariable: 'USER', passwordVariable: 'PASS')]) {
                        sh "docker login -u ${USER} -p ${PASS}"
                        sh "docker run -d -p 3030:3000 ${USER}/node-app:v1"
                    }
                }
            }

        }
        post{ 
            success { 
                slackSend(message: "success tes")
            }
            failure { 
                slackSend(message: "failure Run")
            }
        }

    }
```

Runing app

1- create docker file to build image for jenkins slave

Dockefile_slave Code.

```
FROM ubuntu

USER root
RUN apt-get update -y
RUN apt-get install -y openssh-server
# RUN service ssh start

RUN apt-get install openjdk-11-jdk -y

RUN apt-get install git -y

RUN apt-get install apt-transport-https curl gnupg-agent ca-certificates software-properties-common -y
RUN curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
RUN add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" -y
RUN apt-get install docker-ce docker-ce-cli containerd.io -y

RUN mkdir /root/.ssh
COPY id_rsa.pub /root/.ssh/authorized_keys
ENTRYPOINT service ssh start && bash

```

2- create container from this image and configure ssh

ssh already cofigured with docker file only need to let id_rsa.pub in the same Dir and configure id_rsa with jenkins Credintials ```

docker build -t amrtarek6/jenkins_slave:version -f Dockefile_slave .
docker run -it -d --name slave -v /var/run/docker.sock:/var/run/docker.sock amrtarek6/jenkins_slave:version

```
