OpenStack Stack Show

OpenStack is an open-source cloud computing platform that provides infrastructure-as-a-service (IaaS) solutions for managing and deploying virtual machines and other resources. It allows users to create and manage instances, volumes, networks, and other components required for building and operating a cloud environment.

One of the key features of OpenStack is the ability to create and manage stacks. A stack in OpenStack is a collection of resources that are created and managed as a single unit. It allows users to define and deploy a complete infrastructure by specifying a template that describes the desired state of the resources.

The openstack stack show command is used to display the details of a specific stack. It provides information about the stack's name, UUID, status, creation time, and other relevant details.

To use the openstack stack show command, you need to have the OpenStack command-line client installed and configured. Once you have set up the client, you can run the command with the stack name or UUID as an argument.

Here is an example of how to use the openstack stack show command:

openstack stack show my-stack

In this example, my-stack is the name of the stack we want to show the details for. If the stack exists, the command will display information about the stack, such as its ID, status, and associated resources.

The output of the openstack stack show command is in a JSON format that provides a detailed description of the stack. It includes information about the stack's resources, their current status, and any outputs specified in the stack template.

Here is an example of the output of the openstack stack show command:

{
    "description": "My Stack",
    "id": "3f4bdfb2-45a6-4d10-ae1b-3e394e28ef14",
    "stack_name": "my-stack",
    "creation_time": "2022-01-01T00:00:00Z",
    "stack_status": "CREATE_COMPLETE",
    "stack_status_reason": "Stack create completed successfully",
    "outputs": [
        {
            "output_value": "192.168.0.10",
            "output_key": "InstanceIP",
            "description": "IP address of the instance"
        }
    ],
    "resources": [
        {
            "resource_name": "my-instance",
            "physical_resource_id": "f5f1925c-2591-4a09-a2b5-0b1e9e6f71d2",
            "resource_type": "OS::Nova::Server",
            "resource_status": "CREATE_COMPLETE",
            "resource_status_reason": "state changed"
        },
        {
            "resource_name": "my-volume",
            "physical_resource_id": "e85d7407-0d69-4e2e-8b95-749c9162d4af",
            "resource_type": "OS::Cinder::Volume",
            "resource_status": "CREATE_COMPLETE",
            "resource_status_reason": "state changed"
        }
    ]
}

In the example output above, we can see that the stack has the name my-stack and was created on 2022-01-01. The stack's status is CREATE_COMPLETE, indicating that it has been successfully created. The stack has two resources: an instance (OS::Nova::Server) and a volume (OS::Cinder::Volume).

The outputs section provides information about any outputs specified in the stack template. In this example, the stack has one output called InstanceIP, which represents the IP address of the instance.

Using the openstack stack show command, you can quickly gather information about a stack's status, resources, and outputs. This can be useful for troubleshooting or monitoring purposes, as well as for gaining insights into a stack's current state.

The above diagram represents the relationship between the stack, its resources, and outputs. The stack has a one-to-many relationship with resources, as it can contain multiple resources of different types. Additionally, the stack can have one or more outputs that provide information or data to the user.

In conclusion, the openstack stack show command is a powerful tool for displaying detailed information about a specific stack in an OpenStack environment. It helps users understand the stack's current state, its associated resources, and any outputs defined in the stack template. By using this command, users can effectively manage and monitor their OpenStack infrastructure.
