我有两个yaml文件,如下所述
试验1.yaml
resources:
server_group_1:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 5] }
policies: [ { get_param: [server_group_types, 5] } ]
server_group_2:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 8] }
policies: [ { get_param: [server_group_types, 8] } ]
output:
check_1:
description: Name of the instance
value: { get_attr: [check_1, vname] }
测试2.yaml
resources:
server_group_4:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 4] }
policies: [ { get_param: [server_group_types, 4] } ]
server_group_9:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 7] }
policies: [ { get_param: [server_group_types, 7] } ]
output:
check_6:
description: Name of the instance
value: { get_attr: [check_6, vname] }
我想合并这两个文件并创建一个新的输出文件,所以我使用pyyaml,在这个link中发布的顺序是相同的
有人能在不改变顺序的情况下帮助合并这些文件吗? 最后的山药应该是这样的
最终.yaml
resources:
server_group_1:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 5] }
policies: [ { get_param: [server_group_types, 5] } ]
server_group_2:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 8] }
policies: [ { get_param: [server_group_types, 8] } ]
server_group_4:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 4] }
policies: [ { get_param: [server_group_types, 4] } ]
server_group_9:
type: OS::Nova::ServerGroup
properties:
name: { get_param: [server_groups, 7] }
policies: [ { get_param: [server_group_types, 7] } ]
output:
check_1:
description: Name of the instance
value: { get_attr: [check_1, vname] }
check_6:
description: Name of the instance
value: { get_attr: [check_6, vname] }
已更新
我可以使用ruamel.yaml合并文件。。。下面是更新资源的示例代码
代码:
import ruamel.yaml
yaml = ruamel.yaml.YAML()
#Load the yaml files
with open('/test1.yaml') as fp:
data = yaml.load(fp)
with open('/test2.yaml') as fp:
data1 = yaml.load(fp)
#Add the resources from test2.yaml to test1.yaml resources
for i in data1['resources']:
print i,data1['resources'][i]
data['resources'].update({i:data1['resources'][i]})
#create a new file with merged yaml
yaml.dump(data,file('/tmp/lal.yaml', 'w'))
另一种解决方案是使用HiYaPyCo(https://pypi.org/project/HiYaPyCo/),它实现了保留元素顺序的合并。
输出:
下面的示例代码对我合并两个yaml文件很有用
