Perseo fe docker instance fail to start

问题

I am facing with the following issue: I am trying to deploy FIWARE-Perseo to my Centos 7 server as docker instances. Although the perseocore instance runs without a problem, it doesn't happen the same with the perseo front end. It is created but fails to start. From the logs it is clear that the problem is associated to the mongodb:

I have used the instructions from the following link, in a system where Orion and MongoDB were already running as docker instances: Running together with Perseo Core and Orion Context Broker Thank you very much in advance for any help you can provide me.

Please, make sure you use PERSEO_MONGO_ENDPOINT instead of PERSEO_MONGO_HOST.

Anyway, the following code is an example of a docker-compose.yml file you can use to deploy perseo with orion:

version: "3"

services:

    mongo:
       image: mongo:3.2
       networks:
         - main
       volumes:
            - ./mongodata:/data/db

    orion:
       image: fiware/orion
       depends_on:
         - mongo
       links:
         - mongo
       ports:
         - "1026:1026"
       networks:
            main:
                aliases:
                    - orion.docker
       command: -dbhost mongo

    perseo-core:
        image: telefonicaiot/perseo-core:1.1.0
        networks:
            main:
                aliases:
                    - perseo-core
        command: -perseo_fe_url perseo-fe:9090

    perseo-fe:
        image: telefonicaiot/perseo-fe:1.5.0
        ports:
            - 9090:9090
        networks:
            main:
                aliases:
                    - perseo-fe
        depends_on:
            - perseo-core
        environment:
            - PERSEO_MONGO_ENDPOINT=mongo
            - PERSEO_CORE_URL=http://perseo-core:8080
            - PERSEO_LOG_LEVEL=debug
            - PERSEO_ORION_URL=http://orion.docker:1026/v1/updateContext
            - PERSEO_SMTP_HOST=smtp.gmail.com
            - PERSEO_SMTP_PORT=465
            - PERSEO_SMTP_SECURE=true
            - PERSEO_SMTP_AUTH_USER=XXXXX@XXXXX.com
            - PERSEO_SMTP_AUTH_PASS=XXXXX
networks:
    main:
        external: true
