docker - 在Docker镜像中运行 Airflow 命令错误:[Errno 13]权限被拒绝:'/opt/airflow/logs/scheduler/

Question

我正在从docker hub的apache/airflow:latest顶部创建图像，该图像通过本地dag和插件复制。构建本地气流图像之后，我运行了docker run -it local_airflow:latest list_dags命令以列出最近复制的dag，但是得到了输出:

Unable to load the config, contains a configuration error.
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/logging/config.py", line 565, in configure
    handler = self.configure_handler(handlers[name])
  File "/usr/local/lib/python3.6/logging/config.py", line 738, in configure_handler
    result = factory(**kwargs)
  File "/home/airflow/.local/lib/python3.6/site-packages/airflow/utils/log/file_processor_handler.py", line 50, in __init__
    os.makedirs(self._get_log_directory())
  File "/usr/local/lib/python3.6/os.py", line 220, in makedirs
    mkdir(name, mode)
PermissionError: [Errno 13] Permission denied: '/opt/airflow/logs/scheduler/2020-09-03'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/airflow/.local/bin/airflow", line 25, in <module>
    from airflow.configuration import conf
  File "/home/airflow/.local/lib/python3.6/site-packages/airflow/__init__.py", line 47, in <module>
    settings.initialize()
  File "/home/airflow/.local/lib/python3.6/site-packages/airflow/settings.py", line 402, in initialize
    LOGGING_CLASS_PATH = configure_logging()
  File "/home/airflow/.local/lib/python3.6/site-packages/airflow/logging_config.py", line 68, in configure_logging
    raise e
  File "/home/airflow/.local/lib/python3.6/site-packages/airflow/logging_config.py", line 63, in configure_logging
    dictConfig(logging_config)
  File "/usr/local/lib/python3.6/logging/config.py", line 802, in dictConfig
    dictConfigClass(config).configure()
  File "/usr/local/lib/python3.6/logging/config.py", line 573, in configure
    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'processor': [Errno 13] Permission denied: '/opt/airflow/logs/scheduler/2020-09-03'

这是基于基本气流图像构建的Dockerfile:

FROM apache/airflow:latest

USER airflow

ARG REQUIREMENTS_TXT=""
ENV REQUIREMENTS_TXT=${REQUIREMENTS_TXT}

COPY $REQUIREMENTS_TXT $REQUIREMENTS_TXT

ARG AIRFLOW_CONSTRAINTS_URL=""
ENV AIRFLOW_CONSTRAINTS_URL=${AIRFLOW_CONSTRAINTS_URL}

RUN if [ ! -z "${REQUIREMENTS_TXT}" ]; then pip install --user --upgrade pip && \
    pip install --user -r "${REQUIREMENTS_TXT}" \
    --constraint "${AIRFLOW_CONSTRAINTS_URL}"; fi

ARG DAGS_FOLDER="dags/"
ENV DAGS_FOLDER=${DAGS_FOLDER}

COPY dags/ $AIRFLOW_HOME/dags/

ARG PLUGINS_FOLDER="plugins/"
ENV PLUGINS_FOLDER=${PLUGINS_FOLDER}

COPY plugins/ $AIRFLOW_HOME/plugins/

这是docker build命令

docker build . \
    --tag local_airflow:latest \
    --build-arg DAGS_FOLDER="dags/" \
    --build-arg PLUGINS_FOLDER="plugins/" 

Answer 1

问题在于这些文件的所有者(几乎可以肯定)是root。因此，您无权在此进行任何更改。
我建议将COPY命令更改为如下形式:

COPY --chown=airflow ... ...

这会将文件/文件夹的所有权更改为气流。
