Helpful Content 📌

This is a collection of helpful content for the Ansible Zero to Pro Guide. It is not a part of Ansible, but it is helpful for learning Ansible.

Running in Docker-Compose 🐳^🐳

This will get you up and running with ansible. The below configuration will be starting up four docker containers using fedora as the base image with ansible installed.

• Dockerfile

  FROM fedora:latest
  RUN dnf -y install ansible; \
      ansible-doc -t connection -l 
  

• docker-compose.yml

  version: '3.9'
  services:
    target: &target
      tty: true   
      scale: 4
      build:
        context: .
        dockerfile: Dockerfile    
  

• .env

  COMPOSE_PROJECT_NAME=ansible
  

Usage Steps 👣

1. Build the containers

    docker-compose build
   

2. Run the containers

    docker-compose up -d
   

yml

yml is a human-readable data serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted. yml is stored in key value pairs and can be used to serialize data structures such as maps, sequences, and scalars.

yml Syntax

• yml is case sensitive
• Comments are created using the # symbol

Examples 🧩

• key value pairs

  Fruit: Apple
  Vegetable: Carrot
  Liquid: Water
  Meat: Chicken
  

• arrays / lists

  Fruits:
    - Orange
    - Apple
    - Banana
  
  Vegetables:
    - Carrot 
    - Cauliflower
    - Tomato
  

• dictionary / map

  Banana:
      Calories: 105
      Fat: 0.4g
      Carbs: 27g
  
  Grapes:
      Calories: 62
      Fat: 0.3g
      Carbs: 16g
  

• key value / dictionary / lists

  Fruits:
    - Banana:
        Calories: 105
        Fat: 0.4g
        Carbs: 27g
  
    - Grapes:
        Calories: 62
        Fat: 0.3g
        Carbs: 16g
  

Notice the alignment, this is important in yml.

• You can either set a value or a list/dictionary/map but not both

• Dictionaries are an unordered collection while lists are ordered

Useful Commands in Fedora  

• installs core utils

  dnf install coreutils
  

• installs proc utils

  dnf install procutils
  

• check what provides the ps command

  dnf whatprovides ps
  

  • freebie, it’s procps-ng

    dnf install procps-ng
