Create a skill assembly

A skill assembly defines a set of skills should be installed or removed from nodes using add and remove rules.

Prerequisites

Skills are defined.

Create a skill assembly

To create a skill assembly, follow these steps:

Create a file named skill-assembly.json and paste in the following skill assembly definition:

{
  "name": "my-skill-assembly",
  "skills": [
    {
      "action": "add",
      "skill": {
        "name": "courier-runner",
        "channel": "stable",
        "value": ["1.4.6"]
      }
    },
    {
      "action": "add",
      "skill": {
        "channel": "stable",
        "name": "chef-gohai",
        "value": ["1.2.1"]
      }
    },
    {
      "action": "add",
      "skill": {
        "name": "shell-interpreter",
        "channel": "stable",
        "value": ["1.0.5"]
      }
    },
    {
      "action": "add",
      "skill": {
        "name": "inspec-interpreter",
        "channel": "stable",
        "value": ["1.0.6"]
      }
    },
    {
      "action": "add",
      "skill": {
        "name": "restart-interpreter",
        "channel": "stable",
        "value": ["1.0.4"]
      }
    },
    {
      "action": "add",
      "skill": {
        "name": "chef-client-interpreter",
        "channel": "stable",
        "value": ["1.0.6"]
      }
    }
  ]
}

Create the skill assembly:

chef-node-management-cli management assembly create-assembly --body-file skill-assembly.json --profile <NODE_MANAGER_PROFILE_NAME>

The response is similar to the following:

{
"item": {
    "skillAssemblyId": "e2e66c8a-79ff-4bdc-a4cd-739c3f02f9e9"
  }
}

Save the value of skillAssemblyId, you will use it to create a node cohort.

Troubleshooting

Use the assembly find-one-assembly subcommand to verify that the skill assembly was created or updated successfully:

chef-node-management-cli management assembly find-one-assembly --skillAssemblyId <SKILL_ASSEMBLY_ID> --profile <NODE_MANAGER_PROFILE_NAME>

Next steps

Create override settings that define required skill settings.
