Edit and run

Solved: Nginx running in a Dokku hosted app returns unknown directive "auth_basic"





In [163]:



    


# <ignore> start meta code for Jupyter notebook blog 
from importlib import reload
from pprint import pprint



    











In [164]:



    


import nginx_auth_basic_blocker_meta as content
for m in (content, ):
    reload(m)
# </ignore> end meta code for Jupyter notebook blog

Expected outcome

I want to deploy a Dokku hosted Nginx server for serving static files that implements auth_basic so that when a request is made for a file the requester must enter a username and password.

NB: A high level of security is not required. I only want to keep out casual observers.

Actual outcome

When I deploy the app via

# 'docs' is app name
sudo dokku ps:rebuild docs

Dokku almost gets to the end of the deploy and then returns

...unknown directive "auth_basic"...

Update: blocker removed

With a suggestion from @savant aka José Diaz-Gonzalez at https://github.com/gliderlabs

Changed the Nginx ./config from:

--without-http_auth_basic_module \ to ``

Result: Nginx compiles

Apperently the default is that it compiles with the module.

Explicitly compiling with a --with-http_auth_basic_module is rejected.

      # auth_basic_user_file passwords;
    }
    index index.html;
  }
}

Things I tried:

Upgraded to most current version of Nginx:





In [169]:



    


print(content.nginx_version)



    


















    






# Nginx 1.11.8
NGINX_VERSION="1.11.8"
NGINX_TARBALL="nginx-${NGINX_VERSION}.tar.gz"
PCRE_VERSION="8.39"
PCRE_TARBALL="pcre-${PCRE_VERSION}.tar.gz"
ZLIB_VERSION="1.2.8"
ZLIB_TARBALL="zlib-${ZLIB_VERSION}.tar.gz"

result: Still get unexpected behavior.

Changed the location directive to this:

location / {
      # auth_basic           "closed site";
      # auth_basic_user_file /app/nginx/passwords;
      # I have tried this, too.Some posts said the path is relative to nginx.con
      # auth_basic_user_file passwords;
    }

Result: app functions as expected

Changed the Nginx ./config from:

--without-http_auth_basic_module \ to --with-http_auth_basic_module \

Result --with-http_auth_basic_module \ option not recognized and does not compile

link to ./configure in ./bin/compile
