How to deploy spring-cloud-config server in docker-compose? - docker

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/
