I'm using docker-compose to run spring boot application inside a docker container. A spring boot uses embedded tomcat to run.
There is an external folder on a server (/opt/cp/uploads) with images which I would like to access from a spring boot docker container.
Within the docker-compose.yaml file there are following containers defined:
- nginx
- mysql
- springboot-app
nginx and CloudFlare redirect the domain to the spring app on the port 8080. I'd like to access images like this: https://domainname.com/uploads/imageName.png
Using tomcat this was done in server.xml:
<Context docBase="/opt/uploads" path="/uploads"/>
but this option is obviously not available via application.properties with embedded tomcat.
How does one come about this?
My docker-compose.yaml:
version: '3.8'

container_name: cp-mysqldb
environment:
- MYSQL_ROOT_PASSWORD=pass1234

- MYSQL_USER=root
- MYSQL_PASSWORD=pass1234
ports:

volumes:

ports:
- "8080:8080"
depends_on:
- mysqldb
volumes:
- cp-springboot-data:/opt/cp
- ./target/cp-springboot-0.0.1-SNAPSHOT.war:/ROOT.war
command: ["java", "-jar",
"-Dspring.profiles.active=prod",
"ROOT.war"]
restart: always
volumes:
cp-springboot-data: {
}
cp-mysqldb-data: {
}
