# Oracle Cloud Hello World ## Overview Launch, list, and manage your first OCI compute instance. The most common blocker for new OCI users is the `Out of host capacity` error when launching Always Free ARM shapes (VM.Standard.A1.Flex). This error means the data center has no available hosts — it is **not** a permissions issue. The solution is a retry loop that polls until capacity becomes available. **Purpose:** Get a running compute instance on OCI, including the capacity retry pattern that makes Always Free ARM shapes actually usable. ## Prerequisites - **Completed `oraclecloud-install-auth`** — valid `~/.oci/config` with API key authentication - **Python 3.8+** with `pip install oci` installed - A **subnet OCID** in your tenancy (VCN > Subnets in the Console, or use the default VCN) - An **image OCID** for your region (Compute > Custom Images, or list platform images via API) - An **SSH public key** at `~/.ssh/id_rsa.pub` (for instance access) ## Instructions ### Step 1: List Existing Instances ```python import oci config = oci.config.from_file("~/.oci/config") compute = oci.core.ComputeClient(config) instances = compute.list_instances(compartment_id=config["tenancy"]) for inst in instances.data: print(f"{inst.display_name:<30} {inst.lifecycle_state:<12} {inst.shape}") ``` ### Step 2: List Available Shapes and Images ```python # List shapes available in your tenancy shapes = compute.list_shapes(compartment_id=config["tenancy"]) for s in shapes.data: ocp...
