Modern UI for Ansible, Terraform/OpenTofu/Terragrunt, PowerShell and other DevOps tools.

If your project has grown and deploying from the terminal is no longer feasible, then Semaphore UI is the tool you need.

Thank you,Stefan andsteadfasterX, for supporting the project. Your support is invaluable.

Thank you,Thomas andBrian, for your excellent contributions. You solved issues that no one else would have taken on.

Semaphore UI is a modern web interface for managing popular DevOps tools.

Semaphore UI allows you to:

• Easily run Ansible playbooks, Terraform and OpenTofu code, as well as Bash and PowerShell scripts.
• Receive notifications about failed tasks.
• Control access to your deployment system.

1. Projects is a collection of related resources, configurations, and tasks.
2. Task Templates are reusable definitions of tasks that can be executed on demand or scheduled.
3. Task is a specific instance of a job or operation executed by Semaphore.
4. Schedules allow you to automate task execution at specified times or intervals.
5. Inventory is a collection of target hosts (servers, virtual machines, containers, etc.) on which tasks will be executed.
6. Variable Group refers to a configuration context that holds sensitive information such as environment variables and secrets used by tasks during execution.
