| # Resource Provider |
| |
| Resource provider is a new abstraction introduced in Mesos 1.5. Leveraging this, |
| the resource-providing part of Mesos can be easily extended and customized. |
| Before 1.5, this part of the logic is hard-coded in the agent. Resource |
| providers are mainly responsible for updating Mesos about available resources |
| and handling operations on those resources. |
| |
| There are two types of resource providers: Local Resource Providers (LRP) and |
| External Resource Providers (ERP). Local resource providers only provide |
| resources that are tied to a particular agent node, while external resource |
| providers provide resources that are not tied to any agent node (a.k.a. global |
| resources). The resource provider API is designed in such a way that it works |
| for both types of resource providers. In Mesos 1.5, only local resource |
| providers are supported. |
| |
| The resource provider API is an HTTP-based API, allowing resource providers to |
| be running outside the Mesos master or agent. This is important for ERPs. |
| |
| There is a component in the agent, called the Resource Provider Manager, that |
| monitors and manages LRPs on that agent. The same component will be running in |
| the master in the future to monitor ERPs. |
