`Hi all,<br>
<br>
I guess I understood how heat create works. and also the meaning of options<br>
[ suspend, resume, check stack, change stack template ].<br>
<br>
So now whole stack is a single object.<br>
<br>
I am trying to use os_client_config to create heat stack as:<br>
<br>
*heat = os_client_config.make_client('<wbr>orchestration')*<br>
<br>
now heat object has a function create_stack(**kwargs)<br>
<br>
<br>
I tried to use it as:<br>
<br>
template = {<br>
<br>
'description': 'network and instances',<br>
'heat_template_version': '2015-10-15',<br>
'resources': {'net-a': {'properties': {'name': 'network-a'},<br>
'type': 'OS::Neutron::Net'}}<br>
<br>
}<br>
<br>
<br>
*stack = heat.stacks.create(**template)<wbr>*<br>
<br>
it throws error as ERROR: No stack name specified<br>
<br>
so I added new key as *template.update({'stack_name'<wbr>: 'stack-a'})*<br>
<br>
and this time I got error as ERROR: No template specified<br>
<br>
<br>
what would be the proper procedure to launch stack by os_client_config.<br>
<br>
<br>
<br>
<br>

A stack template defines a set of resources like VMs, networks, router..<br>
and the relationship between them. You can create an entire cloud<br>
infrastructure using a template. When creating a stack these resources<br>
will be created so that you dont need to create them individually. Suspend<br>
means , the instances mentioned in the template will be suspended.<br>
Similarly instances will be paused and resumed when stack is paused and<br>
resumed respectively. Change stack template is for changing the<br>
infrastructure created with the template, like upgrading the instances<br>
flavour used in it.<br>
<br>
I do not understand your second question about re running the stack.<br>
<br>
Are you trying to create stacks using python API?<br>

Hi Vijay,<br>
<br>
Thanks for reply.<br>
<br>
Currently I am trying to create a stack using python API, The library I am<br>
using is os_client_config, its a part of OpenstackClient.<br>
<br>
In my last mail I explained how I am trying to create stack through<br>
os_client_config.make_client('<wbr>orchestration') object.<br>
<br>
Can you help me with this, or is there any other library to create stack in<br>
python.<br>
<br>
<br>
Regards<br>
<br>

Hi,<br>
<br>
We installed Openstack devstack on the machine but we are facing an<br>
*authentication<br>
failure error while logging to openstack dashboard*. According to the<br>
observation it is because of the expiry of the token which keystone uses<br>
for the authentication and authorization.<br>
<br>
Can anyone help. Thanks in advance<br>
