ragtime.elasticsearch

A Ragtime plugin for Elasticsearch migrations.

Usage

project.clj

:profiles {:ragtime-elasticsearch
            {:dependencies [[ragtime.elasticsearch "0.1.0"]]
             :plugins [[ragtime/ragtime.lein "0.3.7"]]
             :ragtime {:migrations elasticsearch-migrations/migrations}
             :source-paths ["migrations"]}}

Defining a migration

(ns elasticsearch-migrations
  (:require [clj-http.client :as http]))

(def index "my_index")
(def index-url (memoize #(format "%s/%s" (:url %) index)))

(def create-index
  {:id "0001-create-index"
   :up (fn [es] (http/post (index-url es)))
   :down (fn [es] (http/delete (index-url es)))})

(defn migrations
  "Return a list of migrations to apply."
  []
  (list create-index))

Running migrations

lein with-profile ragtime-elasticsearch ragtime migrate -d "http://localhost:9200" -r "ragtime.elasticsearch"

• -d or --database is your Elasticsearch URL.
• -r or --require should be the value ragtime.elasticsearch so Ragtime uses this library's namespace.

Side effects

Usage of this plugin creates a ragtime index in your Elasticsearch cluster, with a migrations mapping. The id and created_at of applied migrations are stored in each document.
