[Slashoper]

When I want to modify the UTC time zone to Asia/Shanghai time zone in docker, what should I do? below is my docker image ,but it's does not work

FROM apache/airflow:2.2.4-python3.8 USER root RUN apt-get update \ && apt-get install -y --no-install-recommends \ openjdk-11-jre-headless curl procps\ && apt-get autoremove -yqq --purge \ && apt-get clean \ && rm -rf /var/lib/apt/lists/* RUN mkdir /opt/beeline \ && curl -SL https://archive.apache.org/dist/hadoop/core/hadoop-3.0.0/hadoop-3.0.0.tar.gz \ | tar -xzC /opt/beeline \ && curl -SL https://archive.apache.org/dist/hive/hive-2.1.1/apache-hive-2.1.1-bin.tar.gz \ | tar -xzC /opt/beeline \ && curl -SL https://repo1.maven.org/maven2/io/trino/trino-cli/389/trino-cli-389-executable.jar --output /opt/beeline/trino \ && chmod +x /opt/beeline/trino ENV HADOOP_HOME /opt/beeline/hadoop-3.0.0 ENV HIVE_HOME /opt/beeline/apache-hive-2.1.1-bin ENV JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 ENV PATH $PATH:$HIVE_HOME/bin USER airflow COPY ./config/airflow-kube.cfg /opt/airflow/airflow.cfg COPY ./config/timezone.py /home/airflow/.local/lib/python3.8/site-packages/airflow/utils/timezone.py COPY ./config/sqlalchemy.py /home/airflow/.local/lib/python3.8/site-packages/airflow/utils/sqlalchemy.py RUN pip install --no-cache-dir apache-airflow-providers-apache-spark==2.1.0 \ && pip install --no-cache-dir apache-airflow-providers-apache-sqoop==2.1.0 \ && pip install trino \ && pip install trino[sqlalchemy] \ && pip install apache-airflow[password]

Sorry, I didn't express the situation. What I meant was how to modify the time zone deployed by the airflow docker. The default time zone of airflow is UTC time zone

[potiuk]

Same. Change zone in your image. Depends how you build it and what kind of image you have - for example if the image is Debian based you need to search how to change it for debian and build yiour image with the time zone you desire.

Airflow image is a "reference" one - you can extend it as you wish

[Slashoper]

thank you for your reply. I did as you said. The time in the container has indeed changed, but the running time of DAG has not changed. The following is a screenshot of the production environment

my docker file add ENV TZ="Asia/Shanghai"

[potiuk]

Did you recreate the dags? Dags with already created schedule will remain as they were - because they are kept in the Database.

[Slashoper]

Yes , i do . I solved this problem and added the time zone in the configuration file

Hi @Slashoper ,
I have the same problem as you
I want to use the system time to rename my file store in Minio, but the time I print still in UTC timezone
can I see your timezone.py and sqlamy.py to know where I didn't change it?

Hi @potiuk
The time I printed was correct. but the airflow logging time was adding 8 hours.
