Why You Should Update Chef-Client On AWS Opsworks For Chef Automate Nodes


For smooth communication between the Chef server and chef-client, there is a need for the agent software to access the client’s node public key.

It is possible to create a pair of a public-private key in Amazon EC2. The public key is then passed to the AWS OpsWorks API call using the node name. It is recommended that you run the most recent version.

The Importance of Updating Your Chef-Client

There are numerous reasons as to why you should update it on your nodes. These are:

  • To avoid any end of support from the past Chef software releases
  • It will enable you gain more support for Windows such as resources, additional features and properties
  • To help support more resources
  • For security patches
  • To get additional properties of the existing resources


What to Consider Before Making an Update

The latest version of this program comes with new features although some have been removed. For example, the deploy resource has been eliminated from the latest version. Always ensure that the cookbooks you are running in your environment have not been affected by the version changes since they might distort the functionality of your environment in the end. If you want to view the changes that have been made, check the release notes that are normally found on the documentation page of Chef.


How to Make the Update

To update a new version, there is a procedure to be followed. You have to use the updater cookbook that is normally available on the Chef’s software supermarket. The steps to follow are as stated next:

  • Use the Berkshelf to provision your cookbook
  • Create a role with the above cookbook attached to the run list
  • The role should then be assigned to the nodes
  • Trigger the update run on the nodes


Benefits of Chef Automate

With the help of Amazon Web Services OpsWorks, you can easily run Chef Automate server. Provisioning of a Chef server can be accomplished within a couple of minutes, letting the Automate carry out its operations, restorations, software upgrades and backups. This means that you are free to focus on major configuration tasks rather than managing the Chef server.

The Automate server controls your environment’s nodes configurations by sending instructions to chef-client that stores data about nodes and works as your cookbooks central storage point. It offers Chef servers and its premium features with compliance, visibility and workflow.

The Amazon Web Services OpsWorks runs on a cloud instance. These servers are configured to run on the latest Amazon Linux version. Whenever there are some small versions of chef software, the system maintenance automatically updates the version on the servers as soon as it goes through the AWS testing. Extensive AWS testing is done for verifications whether the upgrade is ready for production and that it will not disrupt the environment already in use. This means that lags can appear between the software releases and how available the application is to the current AWS OpsWorks. Your server will also get system maintenance upgrades to the latest Amazon Linux version.
