Escaping colons in YAML

问题

Does anyone know how to escape colons in YAML? The key in my yml is the domain with port number, but the yml file isn't working with this setup:

###BEGIN
production:
### THIS IS THE ONE I'm HAVING TROUBLE WITH ###
8.11.32.120:8000: GoogleMapsKeyforThisDomain
exampledomain.com: GoogleMapsAPIKeyforThatDomain

development:
 GoogleMapsAPIKeyforDevelopmentDomain
###END

I'm using a google maps plugin called YM4R that uses a .yml file to select the different Google Maps API key depending on where my app is being hosted...

So, I'm trying to make 8.11.32.120:8000 the key. Any idea how to do this? (It's in the gmaps_api_key.yml file if you care)

You'll need to put quotes around the key you're having trouble with. I.e.:

"8.11.32.120:8000": GoogleMapsKeyforThisDomain

To answer a comment another way for list items like:

- sed -i "s/driver: .*/driver: pdo_$DB/" etc/config.yaml

is to write them as:

- >-
  sed -i "s/driver: .*/driver: pdo_$DB/" etc/config.yaml

or as:

- 'sed -i "s/driver: .*/driver: pdo_$DB/" etc/config.yaml'
