Configuration tasks performed during deployment

Partition Table manipulation

During image deployment the last partition is enlarged to use all the available disk space. If SWAP property is present an extra swap partition is also added.

File system Resize

This task enlarges the file system of the last partition to use all the available partition space.

Swap partition configuration

If swap partition is added during the image deployment, the swap partition is formated and a swap entry is added to the instance's fstab.

SSH keys removal

All SSH keys found in the image are removed. On Debian and Ubuntu instances where the key creation is not performed automatically, this task will also recreate the deleted keys.

Temporary disable Remote Desktop (RDP) connections

RDP connections are temporarily disabled during Windows configuration. This is done because when sysprep runs, there is a small time interval where the new password is not applied and allowing RDP connections during this time would raise security concerns.

Perform SELinux file system relabeling

For redhat-based images, since the instance's disk is modified during deployment, a full SELinux file system relabeling needs to be performed. This tasks triggers a full file system relabel at the next boot.

Hostname or Computer name assignment

The instance name is assigned as hostname (or Computer Name for Windows instances).

Change password

This task will change the password for the users specified by the USERS property.

File Injection

When this tasks runs, the files specified by the PERSONALITY image property are injected into the instance's hard disk.
