I'm getting an error on cf push when I try to push a yaml file for a memcached service broker:

#cf push

So obviously someethign is wrong with my yaml file. But I don't know what. Here's what I have:

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

  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:

    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

Could I get some help with why this yaml file isn't parsing correctly?

Answer 1

On the first line you have a scalar (domain) followed by a colon (:) followed by a scalar (cloudeast.mycompany.com), this means at the top, non indented, level you start a mapping and domain is a key scalar and cloudeast.mycompany.com a value scalar.

On the next line you should, once more, have a key scalar and it has to be indented at the same level as the previous line (or you finish the top-level mapping with an end of stream (...) or start a new document (---). You start an indented value that is a mapping and the parser doesn't know what you want to do with that.

One can only try and guess what you try to do. If cloudeast.mycompany.com is the name of the domain, you should make that a new indented scalar value (with key name), then the same indentation error occurs for the key machines. and following 3 keys, after that the file is OK:

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

Of course you also leave out the cloudeaset.mycompany.com value. In both the cases the top level of the YAML file will be a mapping with a single key scalar: domain. The value for that key is again a mapping with keys like nats, networks, memcache_broker
