Connect docker oracledb container from node container

Thanks for your kind answer.
I have an problem to connect docker oracledb container from node container.

My purpose is to make node-test access to oracledb’s oracle database and node-test display this message below.

Connection was successful!

My Container

My network

NETWORK ID          NAME                 DRIVER              SCOPE
bf6a2f4cab57        bridge               bridge              local
a51f5d464115        host                 host                local
becb2e792d03        none                 null                local
8aab6a1bd493        oracledb-container   bridge              local

node-test and oracledb are in same network, oracledb-container.

Here is source codes.
My demos come from here -> https://github.com/oracle/node-oracledb/tree/master/examples

dbconfig.js

module.exports = {
  user          : process.env.NODE_ORACLEDB_USER || "test",
  password      : process.env.NODE_ORACLEDB_PASSWORD || "test",
  connectString : process.env.NODE_ORACLEDB_CONNECTIONSTRING || "oracledb:1521/orcl"
};

connect.js is same.

I pinged it’s connection.

node@1098c82e62ef:~$ ping oracledb

64 bytes from 172.17.0.2: icmp_seq=0 ttl=64 time=0.182 ms

round-trip min/avg/max/stddev = 0.148/0.172/0.209/0.026 ms

so, i ran connect.js but i got this message.

node@1098c82e62ef:~$ node connect.js
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
node@1098c82e62ef:~$ 

But if i try to connect to oracledb from host it always works and i can get some data.
How to solve this problem?
