Chef Node Setup and bootstrapping

• We have configured the chef workstation and we have create account in manage.chef.io which is a hosted chef server

• Now we need to create an node.

• Note:

  • Creating a VM in Azure Refer Here
  • Create a VM in AWS Refer Here

• Lab setup for the node-1

  • Create a ubuntu 20 Linux VM (EC2 instance) in AWS and then we will try to boot strap
  • Now we will try to bootstrap the VM Created in AWS using Chef Workstation
  • To do the bootstrap, we need
    • IP address of node
    • Username and password/key file
    • User needs to have sudo permissions because chef client has to be installed.
  • Steps:
    • Ensure you have SSH connection from workstation => Node
    • Workstation needs to provide some info about chef server to the node so the bootstrap should be executed from chef-repo
    • Build a bootstrap command using knife Refer Here

    knife bootstrap 52.10.165.176 --connection-user ubuntu --ssh-identity-file cheflearning.pem --sudo --node-name 'ubuntunode1'
    

    

• Lab setup for the node-2:

  • Create a ubuntu 20 Linux VM in Azure and then lets try to bootstrap
  • Building a bootstrap command

  knife bootstrap <public ip> --connection-user 'qtdevops' --connection-password '<your ip>' --sudo --node-name 'ubuntunode2'
  

  

• Exercise:

1. Bootstrap an ubuntu node to the hosted chef server.
2. Bootstrap a RedHat node to the hosted chef server.
3. Create a ubuntu VM and then try to install apache server and tomcat server
