我有一个yml配置文件,如下所示:
default: &default
aws_access_key: <%= ENV['AWS_ACCESS_KEY'] %>
aws_secret_key: <%= ENV['AWS_SECRET_KEY'] %>
region: <%= ENV['AWS_REGION'] %>
aws_s3_bucket: <%= ENV['AWS_S3_BUCKET'] %>
aws_s3_host: "https://s3-eu-west-1.amazonaws.com/"
development:
<<: *default
我希望在development
中使用所有默认值进行扩展,但要覆盖存储桶名称。我该如何实现?可能这是一个非常基本的问题,但我找不到任何相关的信息。

如果可以使用python,那很简单:
import yaml
# read your first file
with open("basefile.yaml", 'r') as f:
conf = yaml.load(f)
# read your second file
with open("devfile.yaml", 'r') as f:
devconf = yaml.load(f)
# update the first dictionnary with the values of the second
conf.update(devconf)
# write it in a new file
with open("result.yaml", 'w+') as f:
yaml.dump(conf, f)
