[Dachs-support] dachs error

[Nathanaël Jourdane]

Hello Markus,

When I run dachs, the web server doesn't start and I get the following error:

root at 680e6baf4064:/var/gavo# dachs serve start
/usr/lib/python2.7/dist-packages/gavo/base/config.py:600: UserWarning: /var/gavo/etc/

    stream = open(self.baseFilename, self.mode)
IOError: [Errno 2] No such file or directory: u'/var/gavo/logs/dcErrors'

Do you understand why?

Notes:
I use Docker. See Dockerfile attached.
The folder /var/gavo contains only the files I put here with docker COPY command.

Thank you.
