Chronos Role

This guide explains how to set up and run Chronos (a part of the Mesos framework) inside a Docker container using the image indigodatacloud/chronos:latest. This role is designed specifically for deploying Mesos as part of the INDIGO-DataCloud project.

Role Variables

• zookeeper_client_port (default: 2181) — the port used for Zookeeper client connections

• zookeeper_peers (optional) — a list of Zookeeper server addresses. You can also specify these in an inventory file with the group named [zookeeper_servers].

• chronos_version (default: latest) — the version of Chronos you want to use

• chronos_image (default: indigodatacloud/chronos:{{chronos_version}}) — the image to be used for Chronos

• chronos_framework_name (default: chronos) — the name that will be used for registering the Chronos framework with Mesos

SSL-specific options:

• chronos_password — the password for basic authentication
• chronos_username (default: admin) — the username for basic authentication
• generate_random_pass (default: true) — if set to true, a random password will be created for the self-signed certificate
• chronos_key_password — to be provided if generate_random_pass is false
• chronos_pkcs_password — to be provided if generate_random_pass is false
• chronos_jks_password — to be provided if generate_random_pass is false

Dependencies
