Question

当我尝试为memcached服务代理推送yaml文件时，我在cf push上收到错误：

#cf push

显然，我的yaml文件有些错误。但我不知道是什么。这就是我所拥有的：

domain: cloudeast.mycompany.com
  nats:  secret
    machines:
      - 10.10.100.10
    password: secret
    port: 4222
    user: nats

  networks:
    apps: default
    management: default

        zone2:

    plans:
      small:
        backup: 0
        async_backup: 1
        eviction_policy: LRU
        max_idle_seconds: 86400
        max_size_used_heap: 100
      medium:
        backup: 0
        async_backup: 1
        eviction_policy: LRU
        max_idle_seconds: 86400
        max_size_used_heap: 200

我可以帮一定解释为什么这个yaml文件没有正确解析吗？

Answer 1

在第一行你有一个标量（domain）后面跟一个冒号（:）后跟一个标量（cloudeast.mycompany.com），这意味着在顶部，没有缩进，您开始映射的级别，domain是一个关键标量，cloudeast.mycompany.com是一个值标量。

在下一行中，您应该再次使用键标量，并且必须缩进与前一行相同的级别（或者使用流末尾完成顶级映射（{{1} }）或启动一个新文档（...）。你启动一个缩进值，这是一个映射，解析器不知道你想用它做什么。

只能尝试猜测你尝试做什么。如果---是域的名称，则应该使其成为新的缩进标量值（使用键cloudeast.mycompany.com），然后对键name发生相同的缩进错误。然后按3个键，之后文件就可以了：

machines

当然你也省略了cloudeaset.mycompany.com的价值。在这两种情况下，YAML文件的顶级将是具有单个键标量的映射：domain: name: cloudeast.mycompany.com # scalar key "name" added nats: secret machines: # this scalar key and next 3 dedented - 10.10.100.10 password: secret port: 4222 user: nats # from here everything as it was networks: apps: default management: default memcache_broker: broker_password: secret memcache: vip: 10.100.100.100:11211 servers: - 10.100.100.101:11211 - 10.100.100.102:11211 plans: small: name: small description: A small cache with no redundency free: true memcache_hazelcast: heap_size: 512M host: src_api: https://memcache-hazelcast.cf-deployment.com password: secret memcache: secret_key: secret hazelcast: max_cache_size: 268435456 machines: zone1: - 10.100.100.101 zone2: - 10.100.100.102 plans: small: backup: 0 async_backup: 1 eviction_policy: LRU max_idle_seconds: 86400 max_size_used_heap: 100 medium: backup: 0 async_backup: 1 eviction_policy: LRU max_idle_seconds: 86400 max_size_used_heap: 200。该键的值再次是使用domain，nats，networks

等键的映射
