What is size and max value for NOMAD_ALLOC_INDEX?

Want to use it in an algorithm and need its bit length.

I believe it’s a Go int, so it will depend on your CPU architecture (it can be 32bits or 64bits):

hashicorp/nomad/blob/main/client/taskenv/env.go#L401


	// clientTaskLocalDir is the local dir from the client's perspective; eg <client_task_root>/local
	clientTaskLocalDir string


	// clientTaskSecretsDir is the secrets dir from the client's perspective; eg <client_task_root>/secrets
	clientTaskSecretsDir string


	cpuLimit         int64
	memLimit         int64
	memMaxLimit      int64
	taskName         string
	allocIndex       int
	datacenter       string
	namespace        string
	region           string
	allocId          string
	allocName        string
	groupName        string
	vaultToken       string
	vaultNamespace   string
	injectVaultToken bool
	jobID            string

Hey, thanks lgfa29. I’ll go with 32 bits on the assumption we’ll stay on this side of 2 billion server instances.
