使用 Nifi-Registry 和 Docker 对 Nifi 流文件进行版本控制和持久化 [英] Versioning and persisting Nifi flowfiles with Nifi-Registry and Docker

问题描述

目前我正在使用最新的稳定版本 Nifi/Nifi-registry 和 Docker.我正在尝试在 Gitlab 中对流文件进行版本化和持久化.我在网上找到了一些信息，但现在它不起作用.所有组件都在工作，我还可以将文件从 Nifi 版本化到 Nifi-Registry，但目前缺少 Gitlab 的最后一步.

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.

--> 我修改providers.xml并将其挂载到容器中

--> I modified and mounted the providers.xml into the container

<flowPersistenceProvider>
  <class>org.apache.nifi.registry.provider.flow.git.GitFlowPersistenceProvider</class>
  <property name="Flow Storage Directory">./versioned_flows</property>
  <property name="Remote To Push">origin</property>
  <property name="Remote Access User">*Name*</property>
  <property name="Remote Access Password">*Token*</property>
</flowPersistenceProvider>

andybody 是否有一些经验，也许还有代码片段?我会很感激的.

Does andybody have some experiences and maybe a code snippet? I would appreciate that.

非常感谢.

推荐答案

虽然是老帖子，但如果对大家有帮助，我会很高兴的.

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

我有以下 docker 文件夹 &它同时运行 nifi 和它是注册表容器.

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

复制 nifi 目录中的 'conf' 文件夹(可以从运行没有卷的容器中获取)

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

运行 docker volume create nifi_data

docker-compose.yml 文件为:

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

注意: 我有自定义属性 (env.properties) &自定义处理器位于扩展"目录下.此外，由于 nifi 在 'nifi' 用户下运行，您可能会遇到权限问题 - 我相信您会解决的 :)

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 :)

providers.xml(取默认的 - 注释文件系统提供程序并取消注释 git 提供程序)

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>

最后是restart.sh文件:

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
