Singularity UI is a single page web app that uses Singularity API to:

• Display information about active and historical requests and deploys and their underlying tasks
• Display task artifacts (the relevant application folder tree), tail and download task logs
• Display slave hosts that are part of the Mesos Cluster and decommission them
• Pause and Delete registered deployable items (Singularity Requests)
• Check / Debug the API JSON payloads for requests, deploys, tasks and statuses
• Register / update the information of Deployable Items (i.e. post Singularity Requests)
• Execute Deploys (Post Deploy requests)
