Installation in virtual environment

Here is a brief description of how to install dib (diskimage-builder) in a required environment

Clone the repository of the source code:

$git clone https://git.openstack.org/openstack/diskimage-builder$ git clone https://git.openstack.org/openstack/dib-utils

Create a virtual environment:

$virtualenv dib-env

Enable virtual environment

$source dib-env/bin/activate

Installation:

$cd diskimage-builder$ pip-- default-time=100 install. $cd dib-utils$ python setup.py install

Make the first mirror image

$export DIB_DEV_USER_USERNAME=centos / / initial username centos$ export DIB_DEV_USER_PASSWORD=password / / initial password password$ export DIB_DEV_USER_PWDLESS_SUDO=YES / / allows sudo$ export DIB_CLOUD_INIT_DATASOURCES= "ConfigDrive", OpenStack "/ / cloud-init datasource is ConfigDrive, OpenStack$ disk-image-create centos7 baremetal dhcp-all-interfaces grub2 install-static devuser-o password

It is strange that the password defined earlier cannot log in after installing the system.

$export LIBGUESTFS_BACKEND=direct (error will be reported if you do not perform step 2) $virt-sysprep-- root-password password:password-a centos7.qcow2 (change password to password)
