サーバーとデータベースをdocker-composeを使用してdockerコンテナに配置しようとしています。NodeJSサーバーのENOTFOUNDをDockerを使用してRedisに
私は現在のようなルックスを持つドッキングウィンドウ・コンファイルを：
databsesに接続version: "2"
services:
api:
build: .
ports:
- "3000:3000"
command: npm run-script docker
networks:

mongodb:

networks:

redis:

ports:
- "6379:6379"
networks:

私のコードは次のようになります。
/**
* Init the Redis db.
* @returns {*|Promise}
*/
init: function (isMaster=false) {
return new Promise(function (resolve, reject) {
logger.logInfo('(rdb.init) Trying to connect to Redis database');
client = redis.createClient("redis://redis:6379");
client.on("error", err => {
logger.logFatal('(rdb.init) Could not connect to redis database - ' + err);
reject(err);
});
client.on("connect",() => {
logger.logInfo('(rdb.init) Successfully connected to redis database');
if (config.CLEAR_REDIS_COLLECTIONS && isMaster) {
logger.logWarn('(rdb.init) CLEAR_REDIS_COLLECTIONS = ' + config.CLEAR_REDIS_COLLECTIONS);
dropCollections().then(() => resolve()).catch(err => reject(err));
} else {
resolve();
}
});
});
}
そして
/*
*Connect to the database
*/
function init(isMaster=false) {
logger.logInfo('(mdb.init) Trying to connect to the database @' + config.DB_URL);
mongoose.Promise = Promise;
// Connect to the db
return mongoose.connect("mongodb://mongodb:27017/stuber", {useMongoClient: true}).then(() => {
logger.logInfo('(mdb.init) Successfully connected to the database');
if (config.CLEAR_MONGO_COLLECTIONS && isMaster) {
logger.logWarn('(mdb.init) CLEAR_MONGO_COLLECTIONS = ' + config.CLEAR_MONGO_COLLECTIONS);
return dropCollections();
} else {
return Promise.resolve();
}
}, err => {
logger.logFatal('(mdb.init) Could not connect to the database - ' + err);
return Promise.reject(err);
});
}
ログクラッシュする前にサーバーから取得しています：

ログによると、サーバーはMongoとRedisデータベースに接続できますが、何らかの理由でRedisに接続できなくなっているようです。私はNode-Mongo-Redisの設定を意図した様々なpremadeドッカーの作成ファイルを試しましたが、これまでに何の仕事もしていませんでした。これについての助けに感謝します。
