A resize operation is implemented by creating a new server and copying thecontents of the original disk into a new one. It is also a two-step process forthe user: the first is to perform the resize, the second is to either confirm(verify) success and release the old server, or to declare a revert to releasethe new server and restart the old one.


I am trying to convert my BASH script to Python and am having difficulties in finding the equivalent code for openstack server show or openstack server list --long. I would like to know what host is my server currently located and use this information for a check before migrating it to another host.

I noticed that when I am creating a new server using Microstack CLI, the server is automatically allocated in the "admin" Project, even if I specified (using --nic port-id) ports that belong to "myProject" project.


On the command line, you need to change a few environment variables, namely OS_USERNAME, OS_PROJECT_NAME and of course OS_PASSWORD, before launching your server. Reference: -openstackclient/pike/cli/authentication.html.


Auth information is driven by openstacksdk, which means that values can come from a yaml config file in /etc/ansible/openstack.yaml, /etc/openstack/clouds.yaml or /.config/openstack/clouds.yaml, then from standard environment variables, then finally by explicit parameters in plays. More information can be found at


Server groups can be used to control the affinity and anti-affinity schedulingpolicy for a group of servers (instances). Whilst this is a useful mechanismfor users such scheduling decisions need to be balanced by a deployersrequirements to make effective use of the available capacity.


For example it may be considered reasonable for a user to be able to requestanti-affinity between a set of 10 servers to support a particularavailability schematic. However a user creating anti-affinity between 100servers would be in direct conflict with a stacking policy intended toavoid fragmentation of the overall cloud capacity.


Values may be changed at any time but will only take effect at the nextserver group or server create. Reducing the quota will not affect anyexisting groups, but new servers will not be allowed into groupsthat have become over quota.






Quotas will only be validated for new requests, so it is possible (as withany default quota change) that some existing projects may already be overquota. No existing groups will be affected, but users will be unable tocreate new groups and/or add servers to groups until they drop below theirquota allowances.


Running openstack keypair create KEY_NAME, where KEY_NAME is the nameof the SSH key pair, is sufficient for generating an SSH private andpublic key. The output will return the private key, which should be keptsomewhere private and inaccessible to others.


Hello Everyone,I have been trying to find an ansible-module that can create a snapshot of a running server/instance on Openstack cloud. I have looked into os_image, os_server_action and os_server modules but couldn't find the option. From the command line you can easily get this snapshot using the command


This is the second in a series of posts that will walk you through using the Openstack-based OVH public cloud. In this post you will get introduced to using the Openstack cli to create an Openstack server.


Just like you needed to create an Openstack user for interacting with the Openstack API, you will need to create a ssh keypair used for connecting to Openstack servers. This can be done within the Openstack Horizon UI.


We need to add a new ssh keypair that the Openstack API can add to servers that are created through the API. To keep things simple I added the same public ssh key that I generated in the first blog post.


You will need to install the openstack cli on the operating system you are using. You can easily find instruction for installing it on whatever OS you prefer to use. I quickly installed it on my Mac laptop with homebrew using the following commands.


Finally list the security groups by running openstack security group list. The default security group which allows all inbound and outbound traffic is named default. I decided to use this default security group for my test rather than create a new one that was more restrictive.

Have you used openstack commands to pull the details of that instance to compare against the state file? That exercise will also tell you if the native openstack client is able to pull all of the metadata. Most of the TF OStack problems I have had were related to an openstack problem and had nothing to do with TF. Good luck


i practically has 3 dedicated compute nodes, 1 compute+storage node(1 server+DAS) and 1 node/network controller. As i read the best practice for networking server is to have this service run on all nodes for redundancy as opposed to running on a single controller where is it fails then all the ecosystem fails too.What is your oppinion? Another thing is the colocation of services as i don't have the necessary number of hardware to deploy every service on it's private hardware. I was thinking that the controller should run the controlling part service of nova, the object storage server and block storage server and the compute+storage server should run nova+object storage+block storage. What do you think of this setup?


how does openstack get along with amd opteron 6300 series? I'm asking this because there is a possibility that i could change from intel to amd, the latter being much cheaper so i can get for the same ammount of money twice and something the number of cores (e5-2630 being a 6 core with ht, and from what i understand i should disable ht)


Server groups allow you to specify set of servers which must run on thesame system (affinity) or must run on different systems (anti-affinity).Generally anti-affinity is good for fault tolerance and loaddistribution while affinity is usefule when you want to minimize networkeffects between your instance.


If your project has multiple networks you will need to specify the network id (unfortunately you need the id not the name). For the default public inet network you would add --nic net-id=0a1d0a27-cffa-4de3-92c5-9d3fd3f2e74d to the openstack command flags.

HardReboot (aka PowerCycle) starts the server instance by physically cuttingpower to the machine, or if a VM, terminating it at the hypervisor level.It's done. Caput. Full stop.Then, after a brief while, power is restored or the VM instance restarted.


Unfortunately, one cannot pass rebuild parameters to the resize function.When the resize completes, the server will be in VERIFY_RESIZE state.While in this state, you can explore the use of the new server'sconfiguration. If you like it, call ConfirmResize() to commit the resizepermanently. Otherwise, call RevertResize() to restore the old configuration.


File is used within CreateOpts and RebuildOpts to inject a file into theserver at launch.File implements the json.Marshaler interface, so when a Create or Rebuildoperation is requested, json.Marshal will call File's MarshalJSON method.


ListOpts allows the filtering and sorting of paginated collections throughthe API. Filtering is achieved by passing in struct field values that map tothe server attributes you want to see returned. Marker and Limit are usedfor pagination.


ResetMetadata will create multiple new key-value pairs for the given serverID.Note: Using this operation will erase any already-existing metadata andcreate the new metadata provided. To keep any already-existing metadata,use the UpdateMetadatas or UpdateMetadata function.


Hi. I booted a Linux (ubuntu 20) machine on the same network and installed python3-openstackclient.

With the same rc-file sourced I was able to connect to OpenStack and list,create,delete containers.


It can be important that instances are registered in the CERN DNS and/or Active Directory before their first boot. For example, this is required for a server to establish a Kerberos identity, or to retrieve an X.509 host certificate.


Note: an alias will create a CNAME entry in the DNS. If you need an "A" entry instead, you can append --LOAD-1- to your alias name. For example, the alias 'myalias' will create a DNS CNAME entry, an alias called myalias--LOAD-1- will create an "A" entry. The server will be reachable by 'myalias' in both cases.


You can only add a server to a server group when you create the server. Not afterwards.To add a server to a server group, use the --hint group=$group-uuid parameter onthe openstack baremetalcompute server create command.


OpenStack is an open source cloud computing platform that is used by organizations to manage and control large scale deployments of virtual machines, such as in a cloud computing or virtual private server environment. OpenStack is a popular choice for organizations because it is scalable, reliable, and provides a high degree of control over the underlying infrastructure.


OpenMetal Private Clouds are deployed with OpenStack to three bare metal servers. These three servers comprise the Private Cloud Core. To OpenStack, these three servers are considered the control plane. Private Clouds are deployed with Ceph, providing your cloud with shared storage. Ceph is an open source software-defined storage solution.
