constraints List of Objects

Nomad job specification constraints allows restricting the set of eligible nodes on which the Chaotic task will run.

• attribute (string) - Specifies the name or reference of the attribute to examine for the constraint.
• operator (string) - Specifies the comparison operator. The ordering is compared lexically.
• value (string) - Specifies the value to compare the attribute against using the specified operation.

The default value constrains the job to run on client whose kernel name is linux. The HCL variable list of objects is shown below and uses a double dollar sign for escaping:

[
  {
    attribute = "$${attr.kernel.name}",
    value = "linux",
    operator = "",
  }
