问题描述

我正在为我从 docker-hub 提取的开发堆栈运行 docker 容器，该映像是为与我的应用程序应该部署的位置不同的时区创建的.

I am running docker container for my development stack which I pulled from docker-hub, the image is created for a different timezone than where my application is supposed to be deployed.

如何在 docker 容器中更改时区?

How do I change timezone in a docker container?

我尝试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

并重新启动容器，但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照@LinPy 的建议进行覆盖，但是如果您想在 Dockerfile 中进行设置，您可以使用 ENV 进行设置，因为 tzdata 已经存在你的基础图片.

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 Central Africa Time

You will see Central Africa Time in both container and Postgres

在 alpine 基础镜像中，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 &&
