CAS, config server and bootstrap outside war file

[Matthieu Marc]

Hi everyone,

I am working on CAS 6.1.5 and I configured a spring configuration server for my spring-boot applications.

The spring config server is working as expected for my CAS instance : I wrote the bootstrap.properties file and put it in the src/main/resources directory before building with gradlew. The war file included the file and the service is starting as expected.

But, I manage my source file with git and I don't want to commit the bootstrap.properties file with content credentials used to connect to the spring config server. With my spring-boot2 application, I do not include this file in the jar file, put the file on my server in a directory called config, and launch the application with the following command :  java -Dloader.path="config" -jar myapp.jar

I tried to do so with CAS, but the bootstrap.properties file is not read as expected.

My question is how to make it working with the bootstrap.properties file outside the jar/war file ? Or are there others options/methods to not include spring config credential in bootstrap.properties commited on the git repository ?

Thanks.

Matthieu,

In our tomcat bin directory, we have a file called setenv.sh with a couple lines like this (among others)

CATALINA_OPTS="$CATALINA_OPTS -Dspring.config.additional-location=/home/uvtomcat/config/bootstrap.yml"

CATALINA_OPTS="$CATALINA_OPTS -Dspring.cloud.config.uri=https://user:pass...@config.local/casconfigserver"

export CATALINA_OPTS

bootstrap.yml (and some other config) gets deployed by jenkins and looks like

spring:

  cloud:

    config:

      username: casuser

      password: Mellon

Ray

Note: do not hard code the username password in setenv.sh, tomcat writes CATALINA_OPTS to log on startup.

Thank you Ray,

But unfortunately, it is not working for me. When adding -Dspring.config.additional-location and/or -Dspring.cloud.config.uri, the application will not retrieve the configuration from the config server.

But. I find that using this configuration : spring.cloud.bootstrap.location  work as expected.

My command line is : /usr/lib/jvm/java-11-openjdk-amd64/bin/java  -Dspring.cloud.bootstrap.location=./config/bootstrap.yml -jar cas.war

I will now be able to write a systemd file to launch the application automatically.
