Uh-oh

I just mentioned trying to deploy an AspNetCore app with Docker, and then I ran into a problem as soon as I started work today = =…

This project uses Oracle as the database. Running it directly was fine before, but running it in Docker threw this error:

ORA-01882: timezone region not found

Looking at the error message, it seems the timezone is wrong. Let's check the time on the server and in Docker respectively:

[root@localhost ~]# date -R
Mon, 29 Nov 2021 17:07:30 +0800

root@9abab841b6b4:/app# date -R
Mon, 29 Nov 2021 09:08:22 +0000

Yep, the timezone setting is indeed wrong…

After some effort with search engines, I found a simple solution:

Just add these two lines at the end of the project's Dockerfile~

#设置时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

Run docker-compose up again, and the problem was indeed solved~
