OpenStack start instance is a command that creates a new instance on your cloud. The CLI or Horizon web interface can be used.
Instances, which are virtual machines running in the cloud and using images from different projects, use a pool of images. They contain the operating system, a user name and password, file storage, and other information.
The boot source image can be a volume or a custom configuration. The boot source can be an existing image on your cloud, or it can be a snapshot.
This option lets you create an image from a snapshot of a particular time. This option is only accessible to cloud administrators.
To create an instance using a snapshot, you must have a valid volume attached to the snapshot that has enough space to boot the image. If the volume does not have enough space to boot an image, it can be deleted before the instance is launched.
Boot source: Select the flavor that best meets your memory, compute capacity, and disk space requirements. In the table of Available flavors, yellow warning icons are displayed for those flavors that do not have enough resources.
Next, specify the amount of CPUs you need and how much disk space is required. If the selected flavour does not meet these conditions, the instance fails to launch. An alert will appear on the Available table.
You can also increase volume size when you choose a version with minimum requirements. This can be used to store additional software when you use a boot volume.
After setting the instance's boot-source, you will be able to select a networking to which you wish to connect it. The nics parameter can accept a list of networks that you want to attach the instance to, or it can be specified as a net-id/net-name/port-id or port-name string.
You can also specify the floating IP address. This can be used to connect your instance to both a project network or to the external internet if using a Router.
To assign an instance to the project network, first you need to connect it to the router which has the external networking configured as its gateway. The external IP addresses must be available on a subnet of the external network.
Then, you must assign the instance to a security group. A security group allows access to your instance via SSH or any other protocol that you have allowed.
If you assign the instance to a securitygroup, then you can use it even if your cloud is not connected. Just configure the network and access the instance using SSH. This is more convenient but does not provide complete access control.
If you do not want to assign the instance to a security group, you can use the --os-delete-security-group option. This returns the instance back to the pool and removes it from the group.
