Creating ISO Images for Deployment

You must have a valid blueprint with the specifications you require for the image. This blueprint must be pushed or imported to Image Builder. To fulfill these requirements, see Creating a Blueprint or Editing a Blueprint.

Perform this procedure to create an ISO image which installs the OS on a bare metal system. At the end of the procedure, an .iso file is created that contains the following:

Standard Anaconda installer ISO
Embedded Oracle Linux system tar file
Kickstart file that installs the commit with the minimum default requirements

The installer ISO contains a preconfigured system image that you can use to install on a bare metal system.

(Optional) Verify that the blueprint for the ISO image is in Image Builder.
```
sudo composer-cli blueprints show myblueprint
```
Create the ISO image.
```
sudo composer-cli compose start myblueprint image-installer
```
While the process is running in the background, the composer image's UUID is displayed.
After the process ends, check the status of the image.
```
sudo composer-cli compose info image-uuid
```
The image's status indicates FINISHED when Image Builder has completed the build process.
Download the ISO image file.
```
sudo composer-cli compose image image-uuid
```
The ISO image file contains a *.tar file which is the OS image to be installed on a system.
(Optional) Mount the downloaded image and extract the contents.
1. Mount the downloaded image.
```
sudo mount -o ro iso-image /mnt
```
  iso-image includes the full path and the name of the ISO image file.
  
  The /mnt/ mount point contains the liveimag.tar.gz file.
2. Extract the contents of the *.tar file
```
tar xvf /mnt/liveimg.tar.gz
```
Select the appropriate method for installing the OS.
For example, you can use the ISO image as an installer when booting a system from a location where you want to automatically load the image to a hard disk. Otherwise, you can extract the image file, as described, and use this file to manually deploy the image to a target environment (such as a cloud environment, virtual machine, and so on).
