Chef Infra Server

[edit on GitHub]

Overview

The Chef Infra Server page (Infrastructure > Chef Servers) lets you connect existing Chef Infra Servers to Chef Automate, view all of the connected Chef Infra Servers, and manage all of the objects on your connected Chef Infra Servers.

The Chef Infra Server acts as a hub for configuration data. The Chef Infra Server stores cookbooks, the policies that are applied to nodes, and metadata that describes each registered node that is being managed by Chef Infra Client.

Nodes use Chef Infra Client to ask the Chef Infra Server for configuration details, such as recipes, templates, and file distributions. Chef Infra Client then does as much of the configuration work as possible on the nodes themselves (and not on the Chef Infra Server).

This scalable approach distributes the configuration effort throughout the organization.

The objects that you can manage from the Chef Infra Server are:

• Cookbooks
• Roles
• Environments
• Data Bags
• Clients
• Nodes
• Policyfiles

Connect Chef Infra Servers to Chef Automate

The Chef Infra Server panel starts out with an empty list of servers.

To add existing Chef Infra Servers to the Chef Automate infrastructure, select Add Chef Server which will request the name, FQDN, and IP address of your Chef Infra Server:

Chef Automate will warn you if you enter an invalid FQDN or IP address:

Once you are finished, select Add Chef Server and you will see your server in the list of Chef Infra Servers.

Connect a Chef Organization to a Chef Infra Server

To view a list of existing organizations on a Chef Infra Server, select a Chef Infra Server from the Chef Servers list, then select the Organizations tab, as shown below:

To create a new organization, see the documentation on setting up a Chef Infra Server.

To add an existing organization, select Add Chef Organization, which opens a dialog box as shown below:

Enter the Name, Projects, Admin User, and Admin Key fields using the same values that were provided when the organization was configured using Knife. Copy the contents of the ~/.chef/USER.pem file and paste it into the Admin Key field. Then select Add Chef Organization to add the organization to the Chef Infra Server.

Access Chef Infra Server Components

The following Chef Infra Server components for an organization can be managed using Chef Automate:

• Cookbooks
• Roles
• Environments
• Data Bags
• Clients

To access these components for an organization, select Chef Servers > Organizations and then select an organization. Refer to the image below:

Nodes

A node is a device that is managed by Chef Infra. During the Chef Infra Client run, the Infra Client retrieves attributes that defines the expected state of the node and a run-list that defines how a node will be configured to that state from the Infra Server. The Infra Client then uses that information to update the node to its expected state.

The Chef Infra Server integration lets you:

• Search for a specific node
• View all nodes
• Details of a node
• Edit Run list
• Edit Attributes
• Manage tags
• Reset a node key
• Delete a node

Search for a Node

Use the search bar on the Nodes tab (Chef Infra Servers > Nodes) to find a node from the list of nodes. Entering the name of a node in the search bar returns nodes matching your search criteria.

Details of a Node

Select a specific node to view the node information, metadata and details of the environment of the node. The first section of the page has the Node Information like Environment, Policy Group and Policy Name. You can also view the Metadata for the node which contains the name of the Chef Server, and name of the Chef Organization.

The above information looks like as shown below:

The next section of the page contains two options:

• Details
• Run List
