如何在 docker-compose 中部署 spring-cloud-config 服务器？

Question

I've got a problem with my docker-compose. I'm trying to create mulitple containers with one spring-cloud-config-server, and im trying to use spring-cloud server with my webapps container.

That's the list of my containers:

• 1 for the BDD (db)
• 1 for spring cloud config server (configproperties)
• 1 for some webapps (webapps)
• 1 nginx for reverse proxying (cnginx)

I already try to use localhost, my config-server name as host in environment variable : SPRING_CLOUD_CONFIG_URI and in boostrap.properties. My 'configproperties' container, use 8085 in the server.xml.

That's my docker-compose.yml

version: '3'
services:
  cnginx:
    image: cnginx
    ports:
      - 80:80
    restart: always
    depends_on:
      - configproperties
      - cprocess
      - webapps
  db:
    image: postgres:9.3
    environment:
      POSTGRES_USER: xxx
      POSTGRES_PASSWORD: xxx
    restart: always
    command:
      - -c
      - max_prepared_transactions=100
  configproperties:
    restart: on-failure:2
    image: configproperties
    depends_on:
      - db
    expose:
      - "8085"
    environment:
      - SPRING_DATASOURCE_URL=jdbc:postgresql://db:5432/mydbName?currentSchema=public
  webapps:
    restart: on-failure:2
    image: webapps
    links:
      - "configproperties"
    environment:
      - SPRING_CLOUD_CONFIG_URI=http://configproperties:8085/config-server
      - SPRING_PROFILES_ACTIVE=docker
    depends_on:
      - configproperties
    expose:
      - "8085"

When i run my docker-compose, my webapps are deploying with somme error like:
- Could not resolve placeholder 'repository.temps' in value "${repository.temps}"

But when i'm using postman and send a request like that :
http://localhost/config-server/myApplication/docker/latest It's working properly, the request return all configuration for 'myApplication'.

I think i have miss somethink, but i don't find it...

Anyone can help me ?

For using springcloud server, we just need to run our webapps after the initialisation of the springcloud server.

#!/bin/bash

CONFIG_SERVER_URL=$SPRING_CLOUD_CONFIG_URI/myApp/production/latest

#Check si le le serveur de config est bien lancé
echo 'Waiting for tomcat to be available'
attempt_counter=0
max_attempts=10
while [[ "$(curl -s -o /dev/null -w ''%{http_code}'' $CONFIG_SERVER_URL)" != "200" ]]; do
    if [ ${attempt_counter} -eq ${max_attempts} ];then
        echo "Max attempts reached on $CONFIG_SERVER_URL"
        exit 1
    fi
    attempt_counter=$(($attempt_counter+1))
    echo "code retour $(curl -s -o /dev/null -w ''%{http_code}'' $CONFIG_SERVER_URL)"
    echo "Attempt to connect to $CONFIG_SERVER_URL : $attempt_counter/$max_attempts"
    sleep 15
done
echo 'Tomcat is available'
mv /usr/local/tomcat/webappsTmp/* /usr/local/tomcat/webapps/
