The error message is clear enough: Error: EACCES: permission denied, which means you have not right to write file to directory /bot

Container changed to run as a bot user.
https://github.com/Chatie/wechaty/blob/master/Dockerfile#L52-L64

When docker bind-mount, it doesn't touch the permission of the directory mounted in. so bot user do not have the permission for that directory, that's why you have this error.
Try to run the following commnad to change the permission for your directory, it will work.

sudo chown 999.999 `pwd`

Thanks @Gcaufy

Confirmed, will look into it to see if we should go back to use root user as before.

@zixia did you fixed this exception? when i try to save the user's avatar, the docker will exit. thanks a lot

Error: EACCES: permission denied, open '/bot/dfgdsg.jpg'

[huan]

Not fix yet, because I'm still thinking about why I change to non-root user before...

It seems we should restore the docker to use the root user to make the life easier.

[Gcaufy]

I agree, docker container they are independent, root should be safe for your host machine.

[huan]

@Gcaufy Ok, let's change it back to use root user.

Is there anyone who wants to make this PR? :)

[huan]

Will close this issue because I believe we had already switch back to use root inside our docker containers.
