Could not write technique 'create_dir'
Description
I have an error with ncf editor and I don't know how to fix it or in which direction to check. I have this problem only on my production server and not on test (...) so I would like to find a solution.
When I click on techniques editor and create a simple techniques with 1 method like "create a directory" I get this message :
"An Error occured! Could not write technique 'create_dir' from path /var/rudder/configuration-repository/ncf, cause is: Error while running post-hook command [u'/var/rudder/configuration-repository/ncf/ncf-hooks.d/post.write_technique.rudderify.sh', u'/var/rudder/configuration-repository/ncf', u'create_dir']
Details: INFO: Alternative source path added: /var/rudder/configuration-repository/ncf Error: Unable to create Rudder Technique files related to ncf Technique create_dir ([Errno 13] Permission denied: '/var/rudder/configuration-repository/techniques/ncf_techniques/create_dir/1.0') Traceback (most recent call last): File "/usr/share/ncf/tools/ncf_rudder.py", line 46, in write_one_technique_for_rudder write_technique_for_rudder(destination_path, metadata) File "/usr/share/ncf/tools/ncf_rudder.py", line 120, in write_technique_for_rudder os.makedirs(path) File "/usr/lib/python2.7/os.py", line 157, in makedirs mkdir(name, mode) OSError: [Errno 13] Permission denied: '/var/rudder/configuration-repository/techniques/ncf_techniques/create_dir/1.0'"
I don't know if the problem is new or old, I have discovered this when I was importing a new NCF techniques over API. I have make an error during the import I wrote "techniques" instead of "technique" in JSON header
{ "path" : "/var/rudder/configuration-repository/ncf",
"*technique*": {
Could be the source of problem ?

Thanks François for reporting your issue!
Maybe rights on your directory /var/rudder/configuration-repository/ncf_techniques are not ok
it should be 775 and be owned by group 'rudder'
besides user 'ncf-api-venv' should be in group 'rudder'

I suppose you talk about /var/rudder/configuration-repository/techniques/ncf_techniques
it should be 775 and be owned by group 'rudder'
On my production and test server the acl are not 775:
drwxrws--- 6 ncf-api-venv rudder 4096 Oct 13 16:02 /var/rudder/configuration-repository/techniques/ncf_techniques
besides user 'ncf-api-venv' should be in group 'rudder'
yes it is
groups ncf-api-venv
ncf-api-venv : ncf-api-venv rudder

You are right :)
it should be 775 and be owned by group 'rudder'
On my production and test server the acl are not 775:
drwxrws--- 6 ncf-api-venv rudder 4096 Oct 13 16:02 /var/rudder/configuration-repository/techniques/ncf_techniques
Ok they seems ok (the 5 is not mandatory ...) Maybe another subdirectory of ncf_techniques don't have correct permissions
You can also run the following command as user ncf-api-venv, maybe you will have more insights:
/var/rudder/configuration-repository/ncf/ncf-hooks.d/post.write_technique.rudderify.sh /var/rudder/configuration-repository/ncf create_dir

And the directory create_dir have strange rights:
d-w--wS--- 2 ncf-api-venv rudder 4096 Oct 13 16:02 /var/rudder/configuration-repository/techniques/ncf_techniques/create_dir/
My umask for ncf-api-venv is 0022 (in production and test)
Updated by Francois BAYART over 8 years ago
- % Done changed from 0 to 100
problem come from an old test (before to have a test server) where I have played with umask in "ncf/ncf-hooks.d/post.write_technique.commit.sh" and "ncf/ncf-hooks.d/post.write_technique.rudderify.sh"
I have restored the umask and all is OK now.
thx
