# 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

address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.

## Enforcement

reported by contacting the project team at [labs@idealista.com](mailto:labs@idealista.com). All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.

Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

## 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.
