H
Health Check
A health check is a command that can be executed periodically to determine whether or not a given task is healthy.
P
Plan
A Plan orders work across pods and assists the Service Scheduler to perform orchestration. A Plan is composed of one or many Phase(s).
Phase
A Phase is an ordered collection of Step(s).
Step
A Step is work that needs to be performed for a given Pod instance.
Pod
A Pod is a group of tasks that share the same resources (e.g., CPU, memory, volumes) and are operated on together.
R
Reservation
Resource Reservation ensures that the resources allocated to a given task aren’t reallocated to any other task in the event of failure, task restart, etc.
Resource Set
A Resource Set is a collection of resources, like CPUs, memory, ports, volumes, etc, that are pre-reserved and can be used to launch task(s) in a given Pod instance. A Pod can be composed of tasks using different resource sets.
S
Strategy
Strategy determines whether children of a given Plan (i.e., Phase) or Phase (i.e., Step) are executed in serial or parallel.
T
Task
A Task is a unit of execution of work.
V
Volume
A Volume represents reserved and persistent storage that is available to a framework across task executions.
