How do i copy a directory with SSL information into kafka-ui docker image-CodePudding

I've got the following configuration:

  ssl-kafka-ui:
    image: provectuslabs/kafka-ui
    container_name: ssl-webui
    logging:
      driver: "json-file"
      options:
        max-size: "2048m"
    ports:
      - "8080:8080"
    volumes:
      - ./ssl/:/var/private/ssl
    restart: always
    depends_on: 
      - ssl-broker-one
      - ssl-zookeeper
    environment:
      - KAFKA_CLUSTERS_0_NAME=local
      - KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS=bud48:9092
      - KAFKA_CLUSTERS_0_ZOOKEEPER=ssl-zookeeper=2181
      - KAFKA_CLUSTERS_0_PROPERTIES_SECURITY_PROTOCOL=SSL
      - KAFKA_CLUSTERS_0_PROPERTIES_SSL_KEYSTORE_LOCATION=/var/private/ssl/kafka.server.keystore.jks
      - KAFKA_CLUSTERS_0_PROPERTIES_SSL_KEYSTORE_PASSWORD=MyServerPassword123
      - KAFKA_CLUSTERS_0_PROPERTIES_SSL_KEYSTORE_TYPE=JKS
      - KAFKA_CLUSTERS_0_PROPERTIES_SSL_TRUSTSTORE_LOCATION=/var/private/ssl/kafka.server.truststore.jks
      - KAFKA_CLUSTERS_0_PROPERTIES_SSL_TRUSTSTORE_PASSWORD=MyServerPassword123
      - KAFKA_CLUSTERS_0_PROPERTIES_SSL_TRUSTSTORE_TYPE=JKS

however when I run it, the docker-container can't find that directory containing the keys

I have also tried going into the container to confirm, but it locks up as soon as I enter a command (see below). bash shell doesn't work either.

docker exec -t ssl-webui /bin/sh

Is there any other way to get the ssl information into the container, or find a default location that is accessible?

Adding this to the docker-compose.yml

    user: "0:0"

solved the permissions issue
