Deprecation: Cloud plugin replaced by the Cloud_V2 plugin (OHAI-8)

[edit on GitHub]

In Ohai/Chef releases 13 we replaced the existing Cloud plugin with the Cloud_v2 plugin. This was done by having the Cloud_v2 plugin populate both node['cloud'] and node['cloud_v2']. The Cloud_v2 plugin includes a different data format that resolves many of the longstanding bugs in the existing Cloud plugin.

Remediation

If you have a cookbook that relies on data from node['cloud'] you will need to update the code to the new format in Chef Client 13. On a Chef Client 12 or earlier node you can compare the data formats by running ohai cloud and ohai cloud_v2.

Here are examples of the old and new format of the cloud data:

  "public_ips": [
    "52.88.253.144"
  ],
  "private_ips": [
    "172.31.37.209"
  ],
  "public_ipv4": "52.88.253.144",
  "public_hostname": "ec2-52-88-253-144.us-west-2.compute.amazonaws.com",
  "local_ipv4": "172.31.37.209",
  "local_hostname": "ip-172-31-37-209.us-west-2.compute.internal",
  "provider": "ec2"
}
