6.2. Creating a blueprint in the web console interface

Procedure

1. Click Create Blueprint in the upper-right corner.

   The Images dialog box opens.

2. On the Image output page, complete the following steps:

   1. Choose the Release version and the Architecture.
   2. Select the target environment or target environments.
   3. Click Next.

3. Optional: On the File system configuration page, select Use automatic partitioning or Manually configure partitions for your image file system. To manually configure the partitions, complete the following steps:

   1. Click the Manually configure partitions button.

   2. From the dropdown menu, provide details to configure the partitions:

      • For the Mount point field, select one of the following mount point type options:

        • /app
        • /boot
        • /data
        • /home
        • /opt
        • /srv
        • /tmp
        • /usr

        • /var

          You can also add an additional path to the Mount point. For example, if you select /var as the mount point and add /tmp as an additional path, the result is /var/tmp. Depending on the mount point type you choose, the file system type changes to xfs.

      • For the Minimum size partition field of the file system, enter the needed minimum partition size. In the Minimum size dropdown menu, you can use common size units such as GB, MB, or KB. The default unit is GB.

        Minimum size means that RHEL image builder can still increase the partition sizes if they are too small to create a working image.

   3. To add more partitions, click the Add partition button. If you see the "Duplicate partitions: Only one partition at each mount point can be created." error message, you can fix it by performing one of the following actions:

      • Click the Remove button to remove the duplicated partition.
      • Choose a new mount point for the partition you want to create.
   4. After you finish the partitioning configuration, click Next.

4. Optional: On the Additional packages page, complete the following steps:

   1. In the Available packages search, enter the package name.
   2. Click the button to move it to the Chosen packages field.
   3. Repeat the previous steps to search and include as many packages as you want.
   4. Click Next.
