docker OCI runtime create failed

Question

I'm using a following docker-compose file in a java web app project.

version: "3"
services:
  product:
    image: jboss/wildfly
    ports:
      - 8080:8080
    volumes:
      - Product/target/Product.war:/opt/jboss/wildfly/standalone/deployments

The error I'm getting is

ERROR: Named volume "Product/target/Product.war:/opt/jboss/wildfly/standalone/deployments:rw" is used in service "product" but no declaration was found in the volumes section.
Failed to deploy 'Compose: docker-compose.yml': `docker-compose` process finished with exit code 1

Edit OCI runtime create failed:

Following the fix of the path, I'm encountering another error. OCI runtime create failed:

Answer 1

You must add . at the beginning or use an absolute path when mounting a local file into a container. Otherwise Docker will assume it's a named volume, as the error suggests.
