+# Automate Provisioning OpenStack Instance 
+
+- The Ansible playbook will automate the creation of an openstack instance.
+- The playbook contains the neccessary parameters to create the instance. 
+- The parameters include: image, key_name, flavor, network, and security_groups
+- The parameters image, flavor, network, and security groups must be passed in the command line as extra-vars when running the playbook.
+
+### Steps to Create the OS Instance
+1. Run the following commands to set up the OpenStack credentials:  
+**export OS_AUTH_URL= < url-to-openstack-identity > #you can get this url from OS VM  
+export OS_PROJECT_NAME= < project-name >   
+export OS_USER_DOMAIN_NAME= < domain-name > *# (optional)*  
+export OS_PROJECT_DOMAIN_ID= < domain-ID > *# (optional)*  
+export OS_USERNAME= < user-name >  
+export OS_PASSWORD= < password >  # *(optional)***  
+
+2. Run the playbook with the following command and provide the parameters as extra-vars:   
+**ansible-playbook -vv -i "localhost," --connection=local provision_openstack_instance.yml -e "vm_name=< give a name for the VM > image=< image name > flavor=< flavor name > network=< network name > sec_groups= < security groups name >"**
