Ubuntu and Docker: Error response from daemon: error while creating mount source path

I want to use a volume mounted on my container but it throws the next error when trying to run:

docker: Error response from daemon: error while creating mount sourcepath '/var/skeeter/templates': mkdir /var/skeeter: read-only filesystem.

This is my Dockerfile:

FROM maven:3-jdk-13-alpineRUN mkdir -p /var/container/skeeter/templatesWORKDIR /projectADD ./target/skeeter-0.0.1-SNAPSHOT.jar skeeter-0.0.1-SNAPSHOT.jarEXPOSE 8080CMD java -jar skeeter-0.0.1-SNAPSHOT.jar

And this is the run cmd:

docker run -t -p 8080:8080 -v/var/skeeter/templates:/var/container/skeeter/templates --nameskeeter-docker-container skeeter-docker-image:latest

This is the CMD output when i'm checking the directories permissions:

ls -l /var/skeeter/total 4 drwxrwxrwx 2 root root 4096 ago 11 16:45 templatesls -ld /var/skeeter/drwxrwxrwx 3 root root 4096 ago 11 16:45 /var/skeeter/

Update:I created a new Volume and used its name at -v parameter and it runned, but java app cannot find files inside the directory
