If different steps in the deployment run on different machines, how will we handle authentication/authorization? Can we allow testers to deploy to Test but restrict who can deploy to Production? Are changes audited and easy to roll back? Can anyone on the team easily see what is deployed where? Be careful to maintain it and not treat it like throwaway code. How do we distribute files and install applications in parallel to keep downtime to a minimum? What if each server has different settings?Ĭustom logic in scripts. Multiple copies of files renamed during deployment XPath transforms .NET Configuration transform files PowerShellĭeployments often involve many machines. ![]() How will configuration files be modified? Different connection strings, different network paths, different credentials, etc. SSH PowerShell Remoting WinRM WebDeploy PSEXEC Remote DesktopĮach environment is different. How will we invoke these tasks? Is it easy to read the output? How will we detect failures? How do we deal with authentication? Some tasks must execute directly on the remote machine (e.g., configuring IIS sites and Windows Services, installing COM components, making registry changes). How do we distribute these files to remote machines? How do we do this securely and ensure no tampering when transmitting over insecure networks? Binaries (DLLs, EXEs), CSS and JavaScript files, images and other assets, configuration files, and so on. Many files are needed to deploy an application. Along the deployment automation journey, teams often encounter similar problems: Problems/stumbling blocks ![]() Most teams solve these problems themselves, by writing their own deployment automation scripts, by combining tools like WebDeploy and PowerShell Remoting. “Run a script” is where TeamCity begins and ends it’s up to you to write that script. ![]() Unfortunately, while TeamCity provides some high-level build activities like compiling with MSBuild or running NUnit tests, it doesn’t provide any high level deployment related tasks (“Configure IIS”, “Install a Windows Service”, “Update this configuration file”, etc.). You can do this by telling TeamCity to call your script or command-line deployment tool during the build: You can even chain builds in TeamCity to make promoting between Test and Production environments possible. This is useful if you want to deploy it to a test environment for users to test, or even automate deployments straight to production. TeamCity can also be used to deploy your application during the build. You can also combine multiple builds together to form a chain of builds, which is a powerful way to orchestrate an entire continuous delivery solution. It can restore NuGet packages, compile solutions, run unit tests, patch AssemblyInfo files, inspect code quality, and capture code coverage metrics, just to name a few. Scroll through the list of built-in build runners and build features in TeamCity, and you’ll find almost any activity that you could want to perform during a build. TeamCity is a powerful continuous integration and build automation tool. The build server builds the code and runs tests, while Octopus takes care of deployment. Octopus takes over where your build server finishes. Octopus is a deployment automation server for.
