Abstract

The present embodiments relate to a cloud shell extension framework. A cloud infrastructure (CI) service can invoke a cloud shell from a console to the CI. The service may request that context data to be added for use in a terminal session. The cloud shell extension can include a tool or script that can be used to obtain context data or sample code for preparing an environment specific to the service prior to the user interaction with the environment. The cloud shell extension can allow for a service to register an extension in the cloud shell framework, and their extension can be invoked when a client initiates the cloud shell with the service. The extension can allow for the invoked service to forward context data, such as environment variables, to be set in the terminal session for the client.

Description

INCORPORATION BY REFERENCE; DISCLAIMER The following application is hereby incorporated by reference: application Ser. No. 17/321,240 filed on May 14, 2021. The Applicant hereby rescinds any disclaimer of claim scope in the parent application(s) or the prosecution history thereof and advises the USPTO that the claims in this application may be broader than any claim in the parent application(s). BACKGROUND In many instances, a cloud service may require a client to interact with a service via a command line interface (CLI). Example services can include a bastion comprising a computing instance that serves as the public entry point for accessing a private network from external networks like the Internet or a container engine providing a managed, scalable, and highly available service that can be used to deploy containerized applications to the cloud. A cloud shell can be executed between the cloud infrastructure computer and a client device to run the CLI for the service. However, existing cloud shell techniques are in need of improvements, especially with respect to user interaction. SUMMARY The present embodiments relate to a cloud shell extension framework. A first exemplary embodiment provides a method performed by a cloud infrastructure node for implementing a cloud shell extension framework. The method can include receiving, from a client device, a request to initiate a cloud shell. The request can be associated with a service. The method can also include identifying a cloud shell extension associated with the service. This can be performed responsive to receiving the request to initiate the cloud shell. The method can also include executing the cloud shell extension associated with the service to obtain context data specific to the service. The method can also include initiating a terminal session with the client device. The initiation of the terminal session can include the obtained context data.

DETAILED DESCRIPTION The present embodiments relate to implementing a cloud shell extension framework. A cloud infrastructure (CI) service can invoke a cloud shell from a console. However, many services may desire certain data specific to the service to be added for use in a terminal session. For example, a service may desire environment variables set by the client or have code downloaded from an external data source to prepare an environment for a terminal session. The cloud shell plugin framework as described herein can provide CI services (e.g., a bastion, a container engine, or the like) with an ability to obtain and execute preferred variables in obtained context data before the user is provided the terminal session. A first example service can include a CI bastion service. The bastion can provide an operator with secure shell (SSH) access to hosts. A cloud shell session can start a SSH tunnel to a virtual machine instance specific to the CI bastion service. Another example service can include a container engine environment service. The container engine environment service can request a user to generate a cluster configuration file in a cloud shell, and the cloud shell session can start with the configuration file automatically generated. The cloud shell extension can include a tool or script that can be used to obtain context data or pre-determined code for preparing an environment specific to the service prior to the user interaction with the environment. The cloud shell extension can allow for a service to register an extension in the cloud shell framework, and the extension can be invoked when a client initiates the cloud shell with the service
