Building a Single Image

The openstack overcloud image build --all command builds all the images needed for an overcloud deploy. However, you may need to rebuild a single one of them. Use the following commands if you want to do it:

openstack overcloud image build --type {agent-ramdisk|deploy-ramdisk|fedora-user|overcloud-full}

If the target image exist, this commands ends silently. Make sure to delete a previous version of the image to run the command as you expect.

Moreover, you can build the image with an extra element of your choice using the --builder-extra-args argument:

openstack overcloud image build --type overcloud-full \
    --builder-extra-args overcloud-network-midonet

Note

Make sure the element is available in the $ELEMENTS_PATH environment variable

Uploading the New Single Image

After the new image is built, it can be uploaded using the same command as before, with the --update-existing flag added:

openstack overcloud image upload --update-existing

Note that if the new image is a ramdisk, the Ironic nodes need to be re-configured to use it. This can be done by re-running:

openstack overcloud node configure --all-manageable

Note

If you want to use custom images for boot configuration, specify their names in --deploy-kernel and --deploy-ramdisk options.

Now the new image should be fully ready for use by new deployments.
