How to set the container system time to Beijing time?

To set the container system time to Beijing time, you typically need to adjust the timezone settings within the container. Here's how you can do it:

Using Environment Variables: You can set the TZ environment variable to Asia/Shanghai which corresponds to Beijing time. This can be done in the Dockerfile or when running the container.

Example in Dockerfile:
```
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
```

Using tzdata: Install the tzdata package and configure it to use the Beijing timezone.

Example in Dockerfile:

RUN apt-get update && apt-get install -y tzdata && \
    ln -fs /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    dpkg-reconfigure -f noninteractive tzdata && \
    rm -rf /var/lib/apt/lists/*

Using Docker Compose: If you are using Docker Compose, you can set the timezone in the environment section of your docker-compose.yml file.

Example in docker-compose.yml:

version: '3'
services:
  myservice:
    image: myimage
    environment:
      - TZ=Asia/Shanghai
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /etc/timezone:/etc/timezone:ro

Example with Tencent Cloud

If you are deploying your container on Tencent Cloud, you can use services like Tencent Kubernetes Engine (TKE) to manage your containers. Within TKE, you can configure the timezone settings for your pods using the methods described above. Additionally, you can use Tencent Cloud Container Registry (TCR) to store and manage your Docker images, ensuring that the timezone settings are consistent across your deployments.

By setting the timezone correctly, you ensure that your containerized applications behave as expected, especially when dealing with time-sensitive operations.
