Azure Cloud Shell is an interactive, authenticated, browser-accessible shell for managing Azure resources. As a web-based environment, Cloud Shell provides immediate management access to any device with a network connection. Azure Cloud Shell provides a host of tools, including Azure CLI, Azure PowerShell, Ansible, Terraform, Puppet Bolt, kubectl, and many more.
For more details, check out Overview of Azure Cloud Shell.
Azure Cloud Shell is continually working with customers to improve Azure resource management by focusing on the experience and tools most needed by our customers. We invite everyone to view and provide feedback to our roadmap and future investigations. The Azure Cloud Shell team respects and enjoys engaging with our customers, please share our roadmap and provide feedback here in Discussions or Issues.
When you connect to Azure Cloud Shell, we start a container hosting a wide variety of tools, and
connect your browser to a shell process running inside that container. This repository contains the Docker files used to build that container image. It does not contain the code used for the rest of
the Azure Cloud Shell service. The code in this repository may not match exactly to what is running in the Cloud Shell service at any given time. The service is updated periodically and changes are gradually rolled out to different regions over time. There may be a lag of up to 3-4 weeks for changes made here to be reflected in all Cloud Shell regions.
This repository has several uses:
-
Running the Cloud Shell image locally. If you want a curated set of up-to-date command-line tools suitable for managing an Azure environment, but you want to run the tools locally on your own computer instead of in Cloud Shell, you can build the image and run it yourself.
-
Contributing to Cloud Shell. If you would like to propose a new tool for inclusion in Cloud Shell, you can create an issue or submit a Pull Request to request the tool be added. Please ensure that the PR actually builds within GitHub Actions.
The repository does not provide an out-of-the-box replacement for the Azure Cloud Shell service. Azure Cloud Shell provide a user interface integrated into the Azure portal, a web service that manages the infrastructure on which the containers run, and some additional code used inside the container to connect the shell process to the user interface via a websocket.
-
No identity endpoint. In Cloud Shell, we provide a way to automatically obtain tokens for the user connected to the shell. We can't provide this when you run locally, so you have to authenticate explicitly before you can access Azure resources. When using AZ CLI, run
az login; for PowerShell, runConnect-AzAccount. -
No cloud drive. We don't mount the Cloud Drive from your Azure Cloud Shell, so you won't have access to files stored there.
-
Root instead of cloud shell user. In Azure Cloud Shell you always run as a regular user. When running the image locally, you run as root.
The repository contains two Docker configuration files: base and tools. Normally you just have
one Dockerfile and rely on the container registry to cache the layers that haven't changed.
However, we need to cache the base image explicitly to ensure a fast startup time. Tools is built
on top of the base file and starts from an internal repository where the base image is cached, so
that we know when we need to update the base.
When building or using the image locally, you don't need to worry about that. Just build using the instructions below, and be aware that changes to the base layer will take longer to release than changes to the tools.
| Layer | Job |
|---|---|
| Base | Contains large, infrequently changing packages. Changes every 3-4 months. |
| Tools | Contains frequently changing packages. Changes every 2-3 weeks |
Required software
- Docker
- Bash terminal / Powershell
Building base.Dockerfile image from the root repository
docker build -t base_cloudshell -f linux/base.Dockerfile .Building tools.Dockerfile image
docker build -t tools_cloudshell --build-arg IMAGE_LOCATION=base_cloudshell -f linux/tools.Dockerfile . Running bash in the tools.Dockerfile image
docker run -it tools_cloudshell /bin/bashRunning pwsh in the tools.Dockerfile image
docker run -it tools_cloudshell /usr/bin/pwshTesting the Cloud Shell image
docker run --volume /path/to/CloudShell/folder/tests:/tests -it tools_cloudshell /tests/test.shFor more information about bind mounts, please see the Docker documentation. We do expect all test cases to pass if you want your changes to be merged.

Cloud Shell aims to provide a core set of tools for Azure and Microsoft 365 devops scenarios, but we can't include everything. If you just want to use a tool yourself, you can install most utilities into your own home directory inside Cloud Shell. You only need to update the image if you want every Cloud Shell admin to have the tool available.
For a tool to be included in Cloud Shell, it has to be:
- widely useful to Azure administrators
- well-maintained and supported,
- released under a license which permits us to include it
- lightweight in terms of CPU requirements, size on disk, and memory
Please:
- support fetching tokens from Managed Identity if a tool authenticates to Azure services
- add basic tests to the test suite run by GitHub Actions
- consume the tools from the Mariner package repo
In general we avoid:
- alpha, beta, preview or unstable versions of software.
- tools primarily useful for extensive software development, as opposed to DevOps. Consider Visual Studio Codespaces for that.
