如何更改Docker容器中的时区?

How do I change timezone in a docker container?

我试图通过运行更改容器内的时区配置

I tried to change the timezone config within the container by running

echo "Africa/Lusaka" > /etc/timezone

并重新启动了容器，但是我仍然得到相同的时区.

and restarted the container but I still get the same timezone.

推荐答案

您可以在运行阶段按@LinPy的建议进行覆盖，但是如果要在Dockerfile中进行设置，则可以使用ENV进行设置，因为tzdata已经存在于其中.您的基本图片.

You can override as suggest by @LinPy during the run stage, but if you want to set at your Dockerfile you can set using ENV as tzdata is already there in your base image.

FROM postgres:10
ENV TZ="Africa/Lusaka"
RUN date

构建

docker build -t dbtest.

运行

docker run -it dbtest -c"date"

现在您可以通过运行在数据库端进行验证

Now you can verify on DB side by running

显示时区；

您将在容器和Postgres中看到中部非洲时间

You will see Central Africa Time in both container and Postgres

在高山基础图像中，环境变量将不起作用.您将需要运行

in the alpine base image, the environment variable will not work. You will need to run

 RUN ls /usr/share/zoneinfo && \
cp /usr/share/zoneinfo/Europe/Brussels /etc/localtime && \
echo "Africa/Lusaka" >  /etc/timezone && \
