Getting Started with Semaphore

Semaphore provides a GUI that Instructors and Developers can use to interact with ansible playbooks. Some benefits of Semaphore include:

Build, deploy and rollback task
Group playbooks to projects
Manage environments, inventories & repositories
Run playbooks from the browser
Get notifications about playbook runs

Accessing the Dashboard

Runs on control port 4000.

Access via web browser of choice: x.x.x.x:4000

Navigating the Webpage

A Project is a place to separate management activity. Projects are useful for managing different teams, infrastructures, environments or applications.
A Template defines how to run Ansible Playbook. While tasks are running or after a task is completed, you can see the task status and running log.

Relevant Task Templates

Underneath the Management project pane, the Task Template selection will include:

Create Class
Destroy Class

Underneath the Class project pane, the Task Template selection will include:

Create Range
Destroy Range
Revert VM
Reset VM
Rebuild VM
DCO scenario injects
Create Falling Star
Destroy Falling Star

Create Class

To create a class click the run button on the right side of the screen.
A popup will appear asking you to enter the class number and the number of students in the task template.

Important

The class number must start with a ‘U’ for UCWT or a ‘C’ for CWO. The number of students must not have a leading zero.

After successfully running Create Class template, refresh the browser. The new class will appear as a project in the top left.

Tip

If a task fails, the first step is to rerun the task. Occasionally with large builds instructions are not processed by vsphere properly and a 2nd attempt will correct this problem.
