我试图通过Docker与Clojure应用程序连接到MongoDB
我有以下docker组成规则…
catalog-service: build: ./services/catalog ports: - "2000:3000" depends_on: - catalog-datastore restart: always catalog-datastore: image: mongo:3.0 command: mongod --smallfiles --quiet --logpath=/dev/null ports: - "27017:27017" 下面的clojure应用程序的Dockerfile …
FROM clojure COPY . /usr/src/app WORKDIR /usr/src/app CMD ["lein", "ring", "server"]
和下面的连接代码在我的应用程序…
(ns catalog.handler (:import com.mchange.v2.c3p0.ComboPooledDataSource) (:use compojure.core) (:use cheshire.core) (:use ring.util.response) (:require [compojure.handler :as handler] [ring.middleware.json :as middleware] [clojure.java.jdbc :as sql] [compojure.route :as route] [somnium.congomongo :as m])) (def conn (m/make-connection "catalog" :host "catalog-datastore" :port 27017)) (defn get-all [] (m/fetch :catalog)) (defn get-single [id] (m/fetch-one :catalog :where{:_id (Long/parseLong id)})) (defroutes app-routes (context "/catalog" [] (defroutes catalog-routes (GET "/" [] (get-all)) (GET "/:id", [id] (get-single))))) (def app (-> (handler/api app-routes) (middleware/wrap-json-body) (middleware/wrap-json-response)))
当我尝试运行应用程序，我得到错误…
java.lang.AssertionError Assert failed: (connection? conn)
从文档 ：
set the connection globally (m/set-connection! conn) or locally (m/with-mongo conn (m/insert! :robots {:name "robby"}))
看起来你错过了那一点。 ：p
