Atlas

---

Atlas is a tool for automating the deployment, configuration, and maintenance of DevOps engineering systems. It can be run interactively from the command line, or can be run entirely unattended as part of a VSTS build or release defintion. An Atlas workflow revolves around making the appropriate REST API calls to VSTS, Active Directory, and Azure Resource Manager.

There is a REST API for everything. With Atlas you can make the configuration of everything from CI/CD to production servers consistent, reproducable, and reviewable by capturing them as source controlled templates.

Install

Daily builds of the Atlas CLI are available as self-contained downloads.

Platform	Master branch (0.1)	Latest build
Windows x64	Download latest zip
Linux x64	Download latest tar.gz

If you want to use a package manager:

Chocolatey

• Chocolatey users can use choco install atlas-cli -s https://www.myget.org/F/atlas-ci

Features

• YAML or JSON syntax to define workflows and input parameters

• Handlebars template engine enables workflows to be highly flexible

• JMESPath provides query language for inputs, outputs, and data transformations

• Works cross-platform as a .NET Core executable

• Invokes any Azure RM, Azure AD, or VSTS REST API

• From the command line, REST API calls are secured via interactive Active Directory login, similar to az login

• From a VSTS build or release definition, REST API calls are secured via VSTS service connection to Azure

• Renders output values and additional templated files to a target folder

• Operations support conditional executions, retries and looping, and can throwing detailed exceptions

• Extensively detailed log output and safe --dry-run support simplify troubleshooting

• Values which are declared secret are redacted (replaced with xxxx) when written to console output and log files

Limitations

• Does not allow arbitrary code or command-line execution in order to limit what can be done to the machine executing a workflow

• Currently designed for Active Directory authentication for Azure and VSTS resources

• Not yet available as a class library package

Goals

• Packing workflows into zip or tarball archive files, publishing and executing workflows from feed locations

• Establishing a repository for collaboration on common in-progress and stable workflows, and default location for common workflows

• Shared workflows for larger scenarios, e.g. ASP.NET Core services on Kubernetes with VSTS CI/CD, Azure VM clusters, Azure DNS, ATM, and ALB for geo-redundant load balancing and service routing
