running docky build before ak build gives no clue

[rvalyi]

It would be more user friendly if we had a guard when a beginner tries docky build before doing ak build once. Today it breaks hard with:

Step 9/21 : COPY ./templates /templates
 ---> a6cffafb32ac
Step 10/21 : COPY ./links /odoo/links
COPY failed: file not found in build context or excluded by .dockerignore: stat links: file does not exist
ERROR: Service 'odoo' failed to build
Traceback (most recent call last):

and if one does mkdir odoo/links it then breaks with:
