byteshiva / deployment-tool-ansible-puppet-chef-salt.md
Created July 4, 2016 05:35 — forked from jaceklaskowski/deployment-tool-ansible-puppet-chef-salt.md
Choosing a deployment tool - ansible vs puppet vs chef vs salt

Requirements

  • no upfront installation/agents on remote/slave machines - ssh should be enough
  • application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
  • configuration templating
  • environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
  • deployment process run from Jenkins

Solution

VhostMan-Nginx. A small script (and other bits) for creating virtual hosts with Nginx. Use as you wish. Download all the components - put in your path somewhere and run with vhostman-nginx.sh create domain.com app name. It doesn't need the gunicorn_start file if you don't need that.

etcd vs consul vs ???
- What do Etcd, Consul, and Zookeeper do?
- Service Registration:
- Host, port number, and sometimes authentication credentials, protocols, versions
numbers, and/or environment details.
- Service Discovery:
- Ability for client application to query the central registry to learn of service location.
- Consistent and durable general-purpose K/V store across distributed system.
- Some solutions support this better than others.
- Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
- Centralized locking can be based on this K/V store.
