After a while you should see in the Crowbar UI the node with a flashing yellow light.
We can now start the deployment process of the components. To do that mouse over the Barclamps tab and click on OpenStack. A barclamp is a set of data, templates and other necessary logic for applying a particular role to a node, or to some set of nodes. Start by clicking on the Create button for the Database one. Our node is listed in the Database-server column on the right, so we just have to click on Apply to provision MySQL on our node.
You now have to wait until the light turns green. The node reboot two times and execute a chef-client runs to converge toward the assigned role. So good luck ;. As you can see this one is heavier on options, but you can safely leave everything as default and Click Apply. But this is far from the only choice you have, my favorite is Ceph now supported by Inktank in partnership with Dell and integrated with Crowbar but you have to add the corresponding barclamps to your Crowbar admin node.
This proposal contain two different roles, controller or compute. New snapshot state. A share is provided by file storage. You can give access to a share to instances. To create and manage shares, use manila client commands. As an administrator, you can migrate a share with its data from one location to another in a manner that is transparent to users and workloads. Migrate a share with the manila migrate command, as shown in the following example:.
In OpenStack, flavors define the compute, memory, and storage capacity of nova computing instances. To put it simply, a flavor is an available hardware configuration for a server.
It defines the size of a virtual server that can be launched. Flavors can also determine on which compute host a flavor can be used to launch an instance.
For information about customizing flavors, refer to Section 5. If specifying 'auto', a UUID will be automatically generated. Amount of disk space in gigabytes to use for the ephemeral partition.
If unspecified, the value is 0 by default. Ephemeral disks offer machine local disk storage linked to the lifecycle of a VM instance. When a VM is terminated, all data on the ephemeral disk is lost. Ephemeral disks are not included in any snapshots. Amount of swap space in megabytes to use. The default value is 1. That is, the new bandwidth is the same as that of the attached network. Boolean value defines whether the flavor is available to all users. Defaults to True. Key and value pairs that define on which compute nodes a flavor can run.
These pairs must match corresponding pairs on the compute nodes. It can be used to implement special resources, such as flavors that run on only compute nodes with GPU hardware. As of Newton, there are no default flavors.
The following table lists the default flavors for Mitaka and earlier. You can create and manage flavors with the openstack flavor commands provided by the python-openstackclient package. List flavors to show the ID and name, the amount of memory, the amount of disk space for the root partition and for the ephemeral partition, the swap, and the number of virtual CPUs for each flavor:.
Here is an example with additional optional parameters filled in that creates a public extra tiny flavor that automatically gets an ID assigned, with MB memory, no disk space, and one VCPU.
The rxtx-factor indicates the slice of bandwidth that the instances with this flavor can use through the Virtual Interface vif creation in the hypervisor :. If an individual user or group of users needs a custom flavor that you do not want other projects to have access to, you can change the flavor's access to make it a private flavor.
After you create a flavor, assign it to a project by specifying the flavor name or ID and the project ID:. For information about supporting metadata keys, see Section 5. With the appropriate permissions, you can select which host instances are launched on and which roles can boot instances on this host. HOST is an optional parameter. By default, this option is enabled for only the admin role.
To view the list of valid zones, use the openstack availability zone list command. To view the list of valid compute hosts, use the openstack host list command.
To view the list of valid compute nodes, use the openstack hypervisor list command. NUMA topology can exist on both the physical hardware of the host, and the virtual hardware of the instance. The libvirt driver boot process looks at the NUMA topology field of both the instance and the host it is being booted on, and uses that information to generate an appropriate configuration.
If this fails, though, Compute will not continue to try. If a hardware malfunction or other error causes a cloud compute node to fail, you can evacuate instances to make them available again. You can optionally include the target host on the nova evacuate command. If you omit the host, the scheduler chooses the target host. To preserve user data on the server disk, configure shared storage on the target host. When you evacuate the instance, Compute detects whether shared storage is available on the target host.
Also, you must validate that the current VM host is not operational. Otherwise, the evacuation fails. Evacuate the instance.
You can use the --password PWD option to pass the instance password to the command. If you do not specify a password, the command generates and prints one after it finishes successfully. The command rebuilds the instance from the original image or volume and returns a password. The command preserves the original configuration, which includes the instance ID, name, uid, IP address, and so on.
To preserve the user disk data on the evacuated server, deploy Compute with a shared file system. To configure your system, see Section 5. The following example does not change the password.
When you want to move an instance from one compute host to another, you can use the openstack server migrate command. The scheduler chooses the destination compute host based on its settings. This process does not assume that the instance has shared storage available on the target host. For more information, see Section If you see this error, it means you are either trying the command with the wrong credentials, such as a non-admin user, or the policy.
HTTP If you see an error similar to this message, SSH tunneling was not set up between the compute nodes:. ProcessExecutionError: Unexpected error while running command.
The instance is booted from a new host, but preserves its configuration including its ID, name, any metadata, IP address, and other properties. If you are resizing or migrating an instance between hypervisors, you might encounter an SSH Permission denied error. On the first node, obtain a key pair public key and private key. As root, create the folder that is needed by SSH and place the private key that you obtained in step 1 into this folder:.
The nodes must share the same key pair, so do not generate a new key pair for any subsequent nodes. Each instance has a private, fixed IP address that is assigned when the instance is launched. In addition, an instance can have a public or floating IP address. Private IP addresses are used for communication between instances, and public IP addresses are used for communication with networks outside the cloud, including the Internet.
By default, both administrative and end users can associate floating IP addresses with projects and instances. For details on creating public networks using OpenStack Networking neutron , refer to Section 9.
As an administrator using legacy networking nova-network , you can use the following bulk commands to list, create, and delete ranges of floating IP addresses. These addresses can then be associated with instances by end users. By default, floating-ip-bulk-create uses the public pool and eth0 interface values. You should use a range of free IP addresses that is valid for your network. If you are not sure, at least try to avoid the DHCP address range:. Use nmap to check a range's availability.
For example, The Orchestration service provides a template-based orchestration engine. Administrators can use the orchestration engine to create and manage OpenStack cloud infrastructure resources. For example, an administrator can define storage, networking, instances, and applications to use as a repeatable running environment. Templates are used to create stacks, which are collections of resources. For example, a stack might include instances, floating IPs, volumes, security groups, or users.
The Orchestration service offers access to all OpenStack core services through a single modular template, with additional orchestration capabilities such as auto-scaling and basic high availability.
The heat CLI is deprecated in favor of python-openstackclient. For a Python library, continue using python-heatclient. As an administrator, you can also carry out stack functions on behalf of your users. For example, to resume, suspend, or delete a stack, run:. To prevent system capacities from being exhausted without notification, you can set up quotas. Quotas are operational limits.
For example, the number of gigabytes allowed for each project can be controlled so that cloud resources are optimized. Quotas can be enforced at both the project and the project-user level. You now have to be really patient, building Crowbar is a long process, lots of things to download, it took me around 80 minutes, so you can detach from the Byobu session using F6 and do other stuff.
Current Crowbar Roxy version embbed Chef Server v Install the some required tools. I still have to debug the last message saying no root partition.
