Connected Successfully

but I got This type error:

{ Error: getaddrinfo ENOTFOUND mongodb mongodb:27017
    at errnoException (dns.js:50:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'mongodb',
  host: 'mongodb',
  port: 27017 }

To add more detalis to what Sirko mentioned, you should have a line that looks like 127.0.0.1 mongodb in your /etc/hosts file. — klhr

Try "mongodb://olcadmin:[email protected]:27017/admin" instead of "mongodb://olcadmin:olcmongodb@mongodb:27017/admin", if you are using local mongodb
