【问题描述】：
问题：无法将 presto 容器连接到 mongodb 容器。
我有三个正在运行的容器：
[root@localhost tmp]# docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8f6686547c55 mongo "docker-entrypoint.s…" 6 minutes ago Up 6 minutes 0.0.0.0:27017->27017/tcp tmp_mongo_1
0b639ef12c12 mongo-express "tini -- /docker-ent…" 6 minutes ago Up 6 minutes 0.0.0.0:8081->8081/tcp tmp_mongo-express_1
c51178e29a3e prestosql/presto "/usr/lib/presto/bin…" 4 days ago Up About an hour 0.0.0.0:8080->8080/tcp presto
presto 容器可以访问 mongo db（网络方式）：
[root@c51178e29a3e /]# ping mongo
PING mongo (172.20.0.3) 56(84) bytes of data.
64 bytes from tmp_mongo_1.tmp_default (172.20.0.3): icmp_seq=1 ttl=64 time=0.130 ms
64 bytes from tmp_mongo_1.tmp_default (172.20.0.3): icmp_seq=2 ttl=64 time=0.108 ms
也配置了 Presto 属性（/usr/lib/presto/default/etc/catalog/mongodb.properties）：
connector.name=mongodb
mongodb.seeds=mongo:27017
mongodb.credentials=root:example@liran
尝试访问 mongo 的“liran”集合时：
presto> SELECT COUNT(*) FROM mongodb.local.liran;
Query 20191216_154753_00000_sz73z failed: com.mongodb.MongoTimeoutException: Timed out after 30000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=mongo:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=null, userName='root', source='liran', password=<hidden>, mechanismProperties={}}}, caused by {com.mongodb.MongoCommandException: Command failed with error 18: 'Authentication failed.' on server mongo:27017. The full response is { "ok" : 0.0, "errmsg" : "Authentication failed.", "code" : 18, "codeName" : "AuthenticationFailed" }}}]
在 mongo 上我得到：

更改 mongodb.credentials=root:example@local 只会在 local 而不是 liran 出现相同的错误。
最后一件事，当我运行 mongo 容器时，我使用了以下 stack.yml：
[root@localhost tmp]# cat stack.yml
# Use root/example as user/password credentials
version: '3.1'
services:
mongo:
image: mongo
restart: always
ports:
- 27017:27017
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: example
net.tls.mode: disabled
mongo-express:
image: mongo-express
restart: always
ports:
- 8081:8081
environment:
ME_CONFIG_MONGODB_ADMINUSERNAME: root
ME_CONFIG_MONGODB_ADMINPASSWORD: example
