job -> group -> task -> **resources**
|
|---|
The resources stanza describes the requirements a task needs to execute.
Resource requirements include memory, disk space, network, cpu, and more.
job "docs" {
group "example" {
task "server" {
resources {
cpu = 100
memory = 256
network {
mbits = 100
port "http" {}
port "ssh" {
static = 22
}
}
}
}
}
}
resources Parameters
-
cpu(int: 100)- Specifies the CPU required to run this task in MHz. -
iops(int: 0)- Specifies the number of IOPS required given as a weight between 0-1000. -
memory(int: 300)- Specifies the memory required in MB -
network(Network: )- Specifies the network requirements, including static and dynamic port allocations.
resources Examples
The following examples only show the resources stanzas. Remember that the
resources stanza is only valid in the placements listed above.
Memory
This example specifies the task requires 2GB of RAM to operate. 2GB is the equivalent of 2000MB:
resources {
memory = 2000
}
Network
This example shows network constraints as specified in the network stanza which require 1GBit of bandwidth, dynamically allocates two ports, and statically allocates one port:
resources {
network {
mbits = 1000
port "http" {}
port "https" {}
port "lb" {
static = "8889"
}
}
}
