Permission error running a JAR as non-root user on Docker
I did write the following Dockerfiler:
FROM openjdk:8-jdk-alpine
RUN addgroup -g 999 -S appgroup &&
adduser -u 999 -S appuser -G appgroup
USER appuser
COPY myapp.jar /usr/app/myapp.jar
ENTRYPOINT ["java","-jar","/usr/app/myapp.jar"]
When I run the image, I get the follwing error:
main ERROR Unable to create file logs/file.log java.io.IOException: Could not create directory /logs
Could you please tell me what I did wrong?

User appuser does not have write permissions in the current working directory (/, you can verify it with docker run --rm openjdk:8-jdk-alpine pwd), and it seems that your application needs to create a logs/ directory in that working directory.
Possible solutions :
- set the
WORKDIRto a place he can write (/tmpfor example, or/home/appuserif it is created) in theDockerfile
- you can use option
--workdir /path/to/a/folder/where/appuser/can/writewhen issuingdocker runcommand - you can create the
/logsfolder with right permissions (write forappuser)
