yaml config: unclear how to specifiy repeating options

[ovanes]

I started to migrate our ini-file configs to yaml files. In our ini file we have multiple environment variables specified, i.e.

[uwsgi]
...

env=DB_HOST=whateverhost
env=SEARCH_SERVER=whateverserver
...

Now I am stuck, with the migration to enviroment variables to yaml. I tried the following possibilities, which do not work:

uwsgi:
   ...
   env:
      - DB_HOST=whateverhost
      - SEARCH_SERVER=whateverserver

or

uwsgi:
   ...
   env:
      DB_HOST: whateverhost
      SEARCH_SERVER: whateverserver

Any suggestions are very welcome :) And may be dock updates...

with the embedded parser (the 'dumb' one) you can just pass multiple keys:

uwsgi:
    env: KEY1=VAL1
    env: KEY2=VAL2

while with libyaml-based parsers you need to pass them as sequence:

uwsgi:
    env:
        - KEY1=VAL1
        - KEY2=VAL2

The libyaml-parser can be included in pip based installs by creating a new build configuration.
Make sure the libyaml library and development packages are installed on your system.

Assuming a Unix environment

Create a combined config file for default

# Get the current tarball of uwsgi or extract the build dir from pip
cd BUILD_DIR/buildconf
# Assuming default only inherits from base:
cat default.ini base.ini > PATH/default_wlibyaml.ini

Edit default_wlibyaml.ini:

1. Make sure there is only one [uwsgi] line
2. Remove inherit lines
3. Edit the yaml line to: yaml = libyaml

pip install

# If in virtualenv
source /PATH/TO/VENV/bin/activate

UWSGI_PROFILE=/FULL/PATH/TO/default_wlibyaml.ini pip install uwsgi --no-cache-dir -v

Verify

The verbose flag outputs the build messages and you can see a breakdown of the options in there.

You can also verify the dynamic libraries are linked in the binary:

# Also checking for jansson for JSON support
ldd `which uwsgi` | grep -E "yaml|janss"
