What is Semaphore UI?

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.

Key Concepts

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.
