docker的文件流处理_使用Nifi-Registry和Docker对Nifi流文件进行版本控制和持久化
currently I'm playing with the latest stable version Nifi/Nifi-registry and Docker. I'm trying to version and persist flowfiles in Gitlab.
I found several information in the web but right now it's not working. All components are working and I'm also able to version files from Nifi to Nifi-Registry, but the last step to Gitlab is currently missing.
--> I modified and mounted the providers.xml into the container
org.apache.nifi.registry.provider.flow.git.GitFlowPersistenceProvider
./versioned_flows
origin

Does andybody have some experiences and maybe a code snippet? I would appreciate that.
Thanks a lot.
Kind regards,

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)
org.apache.nifi.registry.provider.flow.git.GitFlowPersistenceProvider
./flow_storage
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
