Although it is an old post, I will be happy if it is helpful to anyone.

I have the following docker folder & it runs both nifi & it's registry containers.

Copy the 'conf' folder inside nifi directory (can be taken from running the container without volume)

Run docker volume create nifi_data

The docker-compose.yml file is:

version: "3.7"
services:

nifi:
  container_name: nifi
  image: apache/nifi:1.11.4
  ports:
    - target: 8080
      published: 8080
      protocol: tcp
      mode: host
  restart: always
  environment:
    - NIFI_WEB_HTTP_HOST=0.0.0.0
    - NIFI_JVM_HEAP_INIT=4g
    - NIFI_JVM_HEAP_MAX=6g
    - NIFI_VARIABLE_REGISTRY_PROPERTIES=./conf/env.properties
  volumes:
    - nifi_data:/opt/nifi/nifi-current/
    - ./nifi/extensions:/opt/nifi/nifi-current/extensions
    - ./nifi/conf:/opt/nifi/nifi-current/conf

nifi-registry:
  container_name: nifi-registry
  image: apache/nifi-registry:0.7.0
  ports:
    - target: 18080
      published: 18080
      protocol: tcp
      mode: host
  environment:
    - NIFI_REGISTRY_WEB_HTTP_HOST=0.0.0.0
    - JVM_OPTS=-Xmx512m -Xms512m -XX:MaxPermSize=1g
  volumes:
    - $PWD/registry/providers.xml:/opt/nifi-registry/nifi-registry-current/conf/providers.xml
    - $PWD/registry/flow-storage:/opt/nifi-registry/nifi-registry-current/flow_storage
    - $PWD/registry/database:/opt/nifi-registry/nifi-registry-current/database
volumes:
  nifi_data:
    external: true
networks:
  default:
    external:
      name: nifi-network

Note: I have custom properties (env.properties) & the custom processors are under 'extensions' directory. Also, you may have permissions issue since nifi runs under 'nifi' user - I am sure you will sort it out :)

The providers.xml (take the default one - comment the filesystem provider & uncomment the git provider)

<flowPersistenceProvider>
<class>org.apache.nifi.registry.provider.flow.git.GitFlowPersistenceProvider</class>
<property name="Flow Storage Directory">./flow_storage</property>

And finally the restart.sh file:

chown -R 1000:1000 nifi registry // nifi's user:group
chmod -R 775 nifi registry
chmod -R g+s nifi registry
docker-compose down
docker-compose up -d
