Introduction🧑🏻🎓
An airgapped host doesn't receive or send any direct internet traffic. Create an Airgap Installation Bundle (.aib) on an internet-connected host, then transfer the Airgap Installation Bundle and the chef-automate binary you used to create it to the airgapped host for usage to install or upgrade Chef Automate on that host.
The following article guides you through all the steps to install airgapped in your system. Let’s go! 🫡
Get Chef Automate Installer and Admin Tool
Get the most recent release of the Chef Automate command-line utility.
On a host with an internet connection, download the Chef Automate command-line tool and use it to create an Airgap Installation Bundle.
Prepare Airgap Installation Bundle
Run the following command to download and bundle the software in the recent Chef Automate release.
./chef-automate airgap bundle create
Run this command to download and bundle the software with a certain Chef Automate release.
./chef-automate airgap bundle create --version VERSION
These instructions create the following Airgap Installation Bundle:
automate-<timestamp>.aib.
Deploy the Airgap Installation Bundle
Give the airgapped host the chef-automate binary and the Airgap Installation Bundle. Specify a location to save the Chef Automate command-line tool that is not on your $PATH. Chef-automate is managed and placed into /bin by the Chef Automate installation procedure.
config.toml is created with default values. Chef Automate won't check its release channel for updates online if its upgrade strategy is set to none.
To modify the FQDN and other configuration parameters, edit config.toml. For additional details on configuration settings, refer to Configuring Chef Automate.
A clean install of Chef Automate takes ten minutes to deploy. Accept the terms of service at the command prompt with a y (the keyboard button y); the installer does several pre-flight inspections. Any failing checks provide details on how to fix problems or bypass the examination. Run the deploy command once more after addressing any pre-flight difficulties.
You will notice this after the deployment procedure.
Deploy complete
The automate-credentials.toml file in your current working directory is where the deployment process stores login information.
Chef Automate asks you for a license after you log in.
Configure Data Collection
The procedure is the same for sending data from your Chef Infra Server or Chef Infra Clients to Chef Automate 2. For further details, see Configure Data Collection.
Chef is dedicated to supporting Chef Automate automatic updates and maintaining the stability of the upgrade.
You must first generate an airgap bundle in order to update an airgapped system.
Take the actions on a computer with an internet connection, and prepare an Airgap installation bundle to update your Chef Automate command-line tool. Transfer the package and the command-line tool Chef Automate to the airgapped host, then execute:
sudo chef-automate upgrade run --airgap-bundle </path/to/bundle>
Common Problems
Check that the host's public DNS name is listed as the FQDN in the config.toml file if you are unable to launch Chef Automate.
[global.v1]
faqdn = "<_Public DNS_name_>"
Once the FQDN has been amended and saved, launch
sudo chef-automate config patch config.toml
and attempt to launch Chef Automate once more.
We hope you understood the steps to airgapped installation in Chef.🤗
