 # Contributor Covenant Code of Conduct

 ## Our Pledge

 In the interest of fostering an open and welcoming environment, we as
 contributors and maintainers pledge to making participation in our project and
 our community a harassment-free experience for everyone, regardless of age, body
 size, disability, ethnicity, gender identity and expression, level of experience,
 nationality, personal appearance, race, religion, or sexual identity and
 orientation.

 ## Our Standards

 Examples of behavior that contributes to creating a positive environment
 include:

 * Using welcoming and inclusive language
 * Being respectful of differing viewpoints and experiences
 * Gracefully accepting constructive criticism
 * Focusing on what is best for the community
 * Showing empathy towards other community members

 Examples of unacceptable behavior by participants include:

 * The use of sexualized language or imagery and unwelcome sexual attention or
  advances
 * Trolling, insulting/derogatory comments, and personal or political attacks
 * Public or private harassment
 * Publishing others' private information, such as a physical or electronic
  address, without explicit permission
 * Other conduct which could reasonably be considered inappropriate in a
  professional setting


 ## Our Responsibilities

 Project maintainers are responsible for clarifying the standards of acceptable
 behavior and are expected to take appropriate and fair corrective action in
 response to any instances of unacceptable behavior.

 Project maintainers have the right and responsibility to remove, edit, or
 reject comments, commits, code, wiki edits, issues, and other contributions
 that are not aligned to this Code of Conduct, or to ban temporarily or
 permanently any contributor for other behaviors that they deem inappropriate,
 threatening, offensive, or harmful.

 ## Scope

 This Code of Conduct applies both within project spaces and in public spaces
 when an individual is representing the project or its community. Examples of
 representing a project or community include using an official project e-mail

 - [Authors](#authors)
 - [License](#license)

 ## Getting Started

 These instructions will get you a copy of the role for your ansible playbook. Once launched, it will install an Apache ZooKeeper server.

 ### Prerequisities

 Ansible 2.5.3.0 version installed.
 Molecule 2.19.0 version installed.

 Inventory destination should be a Debian environment.

 Notice that automatically java is installed as dependency.

 For testing purposes, [Molecule](https://molecule.readthedocs.io/) with [Docker](https://www.docker.com/) as driver

 ### Installing

 Create or add to your roles dependency file (e.g requirements.yml):

 ```
 - src: idealista.zookeeper-role
  version: 1.3.0
  name: zookeeper
 ```

 Install the role with ansible-galaxy command:

 ```
 ansible-galaxy install -p roles -r requirements.yml -f
 ```

 Use in a playbook:

 ```
 ---
 - hosts: someserver
  roles:
    - {
 				role: zookeeper
      }
 ```

 ## Usage

 To set multiple versions

 ```
 zookeeper_hosts:
  - host: zookeeper1
    id: 1
  - host: zookeeper2
    id: 2
  - host: zookeeper3
    id: 3
 ```

 ## Testing


 ```sh
 $ pipenv install -r test-requirements.txt --python 2.7
 $ pipenv run molecule test
 ```

 ## Built With

 ![Ansible](https://img.shields.io/badge/ansible-2.5.3.0-green.svg)

 ## Versioning

 For the versions available, see the [tags on this repository](https://github.com/idealista/zookeeper-role/tags).

 Additionaly you can see what change in each version in the [CHANGELOG.md](CHANGELOG.md) file.
