1.1 Minimum Resource Requirements

Confirm that your Oracle Cloud tenancy and target region have sufficient capacity for the required resources before launching the stack.

Ensure that the capacity is enough for the maximum worker node count, and not just the initial node count. The deployment can fail if sufficient compute, networking, or storage resources are unavailable.

Table 1-1 Minimum Resource Requirements

Resource	Minimum or default requirement
OKE Worker node shape	VM.Standard.E3.Flex, VM.Standard.E4.Flex, or VM.Standard.E5.Flex
OKE Worker node OCPUs	6 OCPUs
OKE Worker node memory	32 GB
OKE Worker boot volume	150 GB
OKE Worker node count	1–10 (autoscaling enabled by default)
Autonomous AI Database database instance (if you want stack to deploy it)	Select the type of Autonomous AI Database instance that you want the stack to provision. If you have logged in to OCI with an Oracle Cloud Free Tier account, you can only provision an Always Free Autonomous AI Database instance. If you have a paid account, you can provision Autonomous AI Database for Developers or Paid instance based on your resource requirements. Note: An instance of Autonomous AI Database for Developers uses 4 ECPUs, while the Always Free and Paid options use 2 ECPUs. All instances require a minimum of 20 GB memory.
Load balancer	One public load balancer
File Storage	One file system and mount target
Jump host	This is a temporary instance provisioned by the stack during deployment. It is automatically deleted by the stack on the successful completion of Terraform deployment. It requires 2 OCPUs and 32 GB memory.
