Mastering CI/CD with TeamCity and Octopus Deploy

Understand how TeamCity watches source control, triggers builds, and runs compilation on build agents; plan a setup with a load balancer, shared database (MySQL or SQL Server), and network storage.

Install TeamCity on a Mac by installing the JDK, downloading the Mac OS package, and running runAll.sh to start the TeamCity server and build agent for local development.

Install a TeamCity build agent on Windows by configuring the agent as a Windows service, installing required SDKs, and authorizing the agent to connect securely over HTTPS to TeamCity.

Understand how TeamCity uses projects as containers for build configurations and templates, with root project inheritance to share settings, and how to create, organize, and configure projects and build configurations.

Create a build configuration in TeamCity, connect to a git repository via a VCS root using HTTPS and credentials, then run the build and check the work directory and logs.

Configure a build configuration in TeamCity by adding build steps to restore dependencies and publish a .NET core project, then review logs and the build artifact in the work folder.

Learn how a build artifact—the files produced by compilation—is packaged into a zip via artifact paths in the build configuration, and how ant syntax adds files for Octopus Deploy.

Create and manage multiple build configurations with parameterized VCS routes in TeamCity, leveraging project-level version control settings and repository name variables for reusable, scalable CI/CD workflows.

Parameterize TeamCity build configurations to replace duplicate .NET core steps with a single, reusable workflow by defining repository, solution, and project name parameters and prompts.

Install Octopus Deploy on Windows with the MSI, set up Octopus Manager, configure SQL Server, apply a starter license, and access the server via the browser.

Explore how to structure Octopus Deploy with spaces and create development, staging, and production environments, then add a tentacle to a target server to enable deployments.

Install and configure a Windows tentacle for Octopus Deploy, choosing listening or polling, register to the dev environment, update calamari, and verify health.

Learn how to name and version packages for Octopus Deploy, including tag selectors, and apply branch-based versions like 10.20.30-development or -rc to control QA and production deployments.

Learn to compile a chosen branch in TeamCity and include the build number and branch name in the artifact, preparing branch-aware packages for Octopus Deploy.

Install Octopus Deploy plugin in TeamCity, create an API key in Octopus, and configure a build step to publish packages and metadata to Octopus Deploy, including space and version details.

Define and deploy a project in Octopus Deploy by creating a project, adding steps (such as deploy to IIS), and configuring environments, lifecycles, and rolling deployments.

Define and manage project variables in Octopus Deploy, apply environment and target scopes, and reference values with hashtag curly brackets to adapt deployments across dev and prod.

Explore system variables in Octopus Deploy and learn to access environment, package, release, and deployment details using Octopus.Environment.Name and similar variables.

Learn how to use cloud agents in TeamCity with Amazon Web Services to launch on-demand EC2 instances, terminate idle agents, and optimize costs through profiles, images, keys, and instance types.

Define and customize triggers in TeamCity to auto build on code changes, using VCS and scheduled triggers with branch filters, quiet time, and rules to optimize CI/CD with Octopus Deploy.

Explore how TeamCity Build Features automate builds with assemblyinfo patcher, automatic merge, and commit status publisher, and integrate with GitHub and other VCS for deployment readiness.

Connect TeamCity to GitHub with SSH keys by loading the private key in the VCS route project and the public key on GitHub.

Enable Google open authentication in TeamCity by adding the HTTP-OAUTHv2 module and configuring Google's OAuth client ID, secret, scope, and redirect URI to allow login via Google.

Discover how tenants enable per-client configurations in Octopus Deploy, connect tenants to projects and environments, and enable tenanted deployments across production and development environments.

Learn to transform configuration files in CI/CD by using TeamCity and Octopus Deploy variables to replace appsettings.json values per environment, enabling prod.database.local and dev.database.local values.

Configure AWS or Azure accounts in Octopus Deploy, supply access keys via IAM, use account variables to copy packages to S3 for deployments to prod and dev environments with templates.

Learn to use Octopus Deploy filters to normalize environment names and route deployments, applying ToLower and other string helpers to ensure correct S3 bucket matching for dev and prod.

Configure Octopus Deploy security by mapping users, roles, and groups to spaces and audits; manage release creators, project deployers, and viewers, and review user activity through audit trails.
