CICD:
  CI:
    build:
      - jenkins:
        - list some plugins and their use cases

        - scripted/declarative pipelines (ask for some example where candidate had some participation)
        - best practice for secrets
        - shared library usage and implementation (if candidate used it and how/for which purpose)

        - where and how ansible find targets which needs an update
        - difference between task and playbook
        - check if candidate created some role from the scratch
        - name some resource types(tasks) and their use cases (copy,template,user,file,uri,apt,yum,...)
        - explain architecture which is used in ansible (workstation + targets, agentless infra)
      puppet:
        - explain architecture which is used in puppet (workstation + server + targets,agent on the targets)
        - name some resource types(tasks) and their use cases (file,user,service,package,exec...)
        - what is hiera and what is its use case

    - diff between ENV and ARG (former providing default values for environment variables inside container,latter is only used in build action)
    - diff between CMD and ENTRYPOINT (former set default executable,latter set main command for container,cmd+entrypoint can be used together as well where cmd is used as default action(changeble) and entyrpoint as nonchangable action)
  - kubernetes
    - name some of the resource types and explain their purpose(pod,ingress,replicatincontroller,replicaset,deployment,endpoint)
    - what is ingress and what is its use case (is it mandatory)
