DOCKER PROJECT:


yum install docker -y
systemctl start docker
systemctl status docker

FROM ubuntu
RUN apt-get update -y
RUN apt-get install apache2 -y
COPY index.html /var/www/html/
CMD ["/usr/sbin/apachectl", "-D", "FOREGROUND"]


DOCKER FILE	: To create image by automation.
DOCKER COMPOSE	: To create multiple containers on single server.
DOCKER SWARM	: To create single containers on Multiple server.
DOCKER STACK	: Docker swarm + Docker compose

1. CREATE 3 SERVERS T2.MEDIUM AND INSTALL DOCKER ON ALL OF THEM & CREATE CLUSTER OF IT

yum install docker -y
systemctl start docker
systemctl status docker
docker swarm init
docker node ls


2. INSTALLING JENKINS (MASTER)

#STEP-1: INSTALLING GIT JAVA-1.8.0 MAVEN
yum install git java-1.8.0-openjdk maven -y

#STEP-2: GETTING THE REPO (jenkins.io --> download -- > redhat)
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key

#STEP-3: DOWNLOAD JAVA11 AND JENKINS
amazon-linux-extras install java-openjdk11 -y
yum install jenkins -y
update-alternatives --config java

#STEP-4: RESTARTING JENKINS (when we download service it will on stopped state)
systemctl start jenkins.service
systemctl status jenkins.service


3. CREATE CUSTOM IMAGES AND PUSH TO DOCKERHUB WITH TAGS

DOCKER FILE:
FROM ubuntu
RUN apt-get update -y
RUN apt-get install apache2 -y
COPY index.html /var/www/html/
CMD ["/usr/sbin/apachectl", "-D", "FOREGROUND"]

INDEX.HTML:


PIPELINE:
pipeline {
    agent any

    stages {
        stage('checkout') {
            steps {
                git 'https://github.com/ReyazShaik/dockerproject.git'
            }
        }
        stage('build') {
            steps {
                sh 'docker build -t $image .'
            }
        }
        stage('tag') {
            steps {
                sh 'docker tag $image $repo'
            }
        }
        stage('push') {
            steps {
                sh 'docker login -u reyadocker -p $password'
                sh 'docker push $repo'
            }
        }
        stage('deploy') {
            steps {
                sh 'docker stack deploy bank -c docker-compose.yml'
            }
        }
    }
}

4. GIVE PERMISSIONS

chmod 777 /var/run/docker.sock
systemctl daemon-reload
systemctl restart docker.service


5. WRITE COMPOSE FILE AND PUSH TO GITHUB

services:
  internetbanking:
    image: reyadocker/internetbankingrepo:latest
    ports:
      - "81:80"
    deploy:
      replicas: 3
    volumes:
      - /var/lib/internetbanking
  mobilebanking:
    image: reyadocker/mobilebankingrepo:latest
    ports:
      - "82:80"
    deploy:

      - "84:80"
    deploy:
      replicas: 3
    volumes:
      - /var/lib/loan

COMMAND:
TO DEPLOY : docker stack deploy --compose-file docker-compose.yml stack_name
TO LIST : docker stack ls
TO GET CONTAINERS OF A STACK : docker stack ps stack_name
TO GET SERVICES OF A STACK: docker stack services stack_name
TO DELETE A STACK: docker stack rm stack_name


PORTAINER: its a GUI for managing containers

SETUP:
Must have swarm mode and all ports enable with docker engine
curl -L https://downloads.portainer.io/ce2-16/portainer-agent-stack.yml -o portainer-agent-stack.yml
docker stack deploy -c portainer-agent-stack.yml portainer
docker stack ls
public-ip of swarm master:9000
