【问题描述】：
我在docker-compose.yml 文件中有这个 Nifi 容器的定义。我将默认的 Nifi 端口从 8080 更改为 8181。它工作正常。但是，我无法将flow.xml.gz 复制到 Nifi 容器。
nifi:
image: xemuliam/nifi
network_mode: "host"
ports:
- "8181:8181"
expose:
- "8181"
environment:
- NIFI_WEB_HTTP_PORT=8181
- NIFI_WEB_HTTP_HOST=0.0.0.0
volumes:
- ./src/data_flow_engine/flow.xml.gz:/opt/nifi/conf/flow.xml.gz
- ./src/data_flow_engine/bootstrap.conf:/opt/nifi/conf/bootstrap.conf
当我注释掉- ./src/data_flow_engine/flow.xml.gz:/opt/nifi/conf/flow.xml.gz 时，它运行良好。
这是错误信息：
