## What is an Artifact?

An artifact is simply a smaller component or informational property of a larger object, resource, or service that acts in a manner to produce or determine an intended output. It can also be defined as the logic that defines what elements of a deployment have to be installed and how. These informational pieces are created to be used for the deployment and operation of a system.

## Airctl and Helpers

The following artifacts are used to aid in the implementation and configuration of the different airctl elements.

* *airctl-.tar.gz*: This compressed file contains the airctl binary. This is the primary CLI tool used for management of the Platform9 Self Managed Cloud Platform (SMCP)
* *airctl-scripts-.tar.gz*: This compact file contains all the associated scripts used by airctl
* install.sh: Script to install the downloaded artifacts to proper location on the node
* nodelet.tar.gz: This file contains the nodelet package needed for the management cluster creation. We have nodelet-deb.tar.gz for ubuntu 22.04 OS.

## Offline Packages

The following artifacts are primarily employed for offline (or air-gapged) edge cloud installations.

* *hostagent-.tar.gz*: This file contains the yum or apt repo information for the platform9 agents running on the hosts. Platform9 automatically deploys this and sets up the repository.
  * Note: Depending on the OS of the nodes being onboarded, users might have to specify different variant of this in the airctl-config.yaml
    * Centos7.9: hostagent-.tar.gz
    * RHEL 8.5, RHEL 8.6: hostagent-8-.tar.gz
    * Rocky linux 9.2: hostagent-9-.tar.gz
    * Ubuntu 22.04: hostagent-ubuntu-.tar.gz
* *docker-.tar.gz*: Similar to the file above, it can be installed using Platform9 *airctl* command.
  * Note: Depending on the OS of the nodes being onboarded, users might have to specify different variant of this in the airctl-config.yaml
    * Centos7.9: docker-.tar.gz
    * RHEL 8.5, RHEL 8.6: docker-8-.tar.gz
    * Rocky linux 9.2: docker-9-.tar.gz
    * Ubuntu 22.04: docker-ubuntu-.tar.gz
* *docker-imgs-.tar.gz*: This file contains all the docker images that Platform9 initially requires. Airctl can add it to the cache of every host.
* *pf9-kube-.tar.gz*: This file contains the packages needed for a Kubernetes multi-version implementation
* nodelet-imgs-.tar.gz: It contains the images needed for the management base kubernetes cluster creation.
* kubedu-imgs-.tar.gz: It contains the images needed to bring up the SMCP management plane.
* k8s--.tar.gz: This file contains the images needed for specific kube versions and addons which we upload to DU registry for the workload cluster nodes.

## Installed File Locations

Once setup, all the installed files are located under the `/opt/pf9/airctl` directory.
