Access log file not created in docker container for spring boot aplication

I have a Spring-Boot application that does not create an access log file of the embedded Tomcat server while running inside a docker container. But when run outside of the container it does create a file.


Iam using a custom log configuration:
@Configuration
public class LoggingConfiguration {

@Bean
public WebServerFactoryCustomizer connectorCustomizer(final AccessLogProperties accessLogProperties) {
return tomcat -> {
final JsonAccessLogValve logValve = new JsonAccessLogValve();
logValve.setEnabled(accessLogProperties.isEnabled());
logValve.setBuffered(accessLogProperties.isBuffered());
logValve.setRenameOnRotate(accessLogProperties.isRenameOnRotate());
logValve.setRotatable(accessLogProperties.isRotate());
logValve.setPrefix(accessLogProperties.getPrefix());
logValve.setSuffix(accessLogProperties.getSuffix());
logValve.setPattern(accessLogProperties.getPattern());
tomcat.addContextValves(logValve);
};
}
}



The properties are configured in my application.yml and made available through: AccessLogProperties.class
...
json-access-log:
enabled: true
buffered: false
pattern: "%{yyy-MM-dd'T'hh:mm:ssZ}t %I %l %u %a %r %q %s (%D ms) %{Authorization}i"
rename-on-rotate: true
rotate: true
prefix: chalkup-${ACTIVE_APP_ENVIRONMENT}
suffix: .access
...



locally a file is created in the root of my project under ./logs and there a file chalkup-local.access is created and appended with info.


sofar running in intellij results in the access file I need.


When I run the app in a docker container. No file is created:


docker config:
FROM eclipse-temurin:21-alpine
ADD ./target/chalkup-*.jar chalkup.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "/chalkup.jar"]

chalk-up:
container_name: chalk-up
build:
dockerfile: Dockerfile
context: .
environment:
ACTIVE_APP_ENVIRONMENT: test
entrypoint:
- java
- -agentlib:jdwp=transport=dt_socket,address=*:5005,server=y,suspend=n
- -Djava.security.egd=file:/dev/./urandom
- -jar
- /chalkup.jar
- -Dspring.profiles.active=local
volumes:
- /tmp/logs:/logs
ports:
- "8080:8080"
- "5005:5005"
depends_on:
- wiremock



But when I look in the /logs dir in the running container. I only see the regular logfile but NOT the access log file


Changed the basedir, no success
changed read/write permissions in the container. No success
configured the regular access log
server:
tomcat:
basedir: .
accesslog:
enabled: true


But this one also does not appear in the container, while it does when running outside the container
