My-jenkins-docker-kubernetes-installation

1. First step #install and configure docker on your jenkins ubuntu server sudo apt update sudo apt install docker.io -y sudo systemctl start docker sudo systemctl enable docker.service

2. second step #install, configure, and start jenkins sudo apt-get update sudo apt install openjdk-11-jdk sudo wget -O /usr/share/keyrings/jenkins-keyring.asc
   https://pkg.jenkins.io/debian/jenkins.io-2023.key echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc]
   https://pkg.jenkins.io/debian binary/ | sudo tee
   /etc/apt/sources.list.d/jenkins.list > /dev/null
   sudo apt-get install jenkins sudo systemctl start jenkins sudo usermod -aG docker jenkins sudo systemctl restart docker.service sudo echo "jenkins ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/jenkins

3. third step #install AWSCLI sudo apt update -y sudo apt install unzip wget -y sudo curl https://s3.amazonaws.com/aws-cli/awscli-bundle.zip -o awscli-bundle.zip sudo apt install python3 -y sudo apt install unzip python3 -y sudo unzip awscli-bundle.zip sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

4. FOURTH STEP #Install wget if not installed sudo apt install wget -y sudo wget https://github.com/kubernetes/kops/releases/download/v1.22.0/kops-linux-amd64 sudo chmod +x kops-linux-amd64 sudo mv kops-linux-amd64 /usr/local/bin/kops

5. FIFTH STEP #Install kubectl sudo curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl sudo chmod +x ./kubectl sudo mv ./kubectl /usr/local/bin/kubectl

6. SIXTH STEP #Create an IAM role from AWS console or CLI with the below policies AmazonEC2FullAccess AmazonS3FullAccess IAMFullAccess AmazonVPCFullAccess

7. SEVENTH STEP #create an S3 bucket

8. EIGHT STEP #Add enviromental variable in bashrc vi .bashrc export NAME=jenkinstechjourney.k8s.local export KOPS_STATE_STORE=s3://mybucketlist.local

9. NITHS STEP #create ssh before configuring cluster ssh-keygen

10. TENTH STEP #Create kubernetes cluster defintion on s3 bucket kops create cluster --zones us-east-1a --networking weave --master-size t2.medium --master-count 1 --node-size t2.medium --node-count=2 ${NAME}

copy the sshkey into your cluster to be able to access your kubernetes node from the kops server

kops create secret --name ${NAME} sshpublickey admin -i ~/.ssh/id_rsa.pub
