OCI Limits

Summary

These are some OCI CLI queries for getting limits and availability for resources in the tenancy.

Find All VCN Limit Names

I used the following commands to get the names of limits for Virtual Cloud Networks (VCNs) in my tenancy. I used the printf command to get the quoting right for the query:

printf -v query 'data[?contains("service-name",%s)].{"Name":name,"Description":description}' "'vcn'"
oci limits definition list              \
    --compartment-id ${tenancy_ocid}    \
    --query "${query}"                  \
    --all                               \
    --output table

The output for always-free OCI account is:

Get the Used and Available Counts for VCNs

Run the following command to get available and used counts for VCNs:

oci limits resource-availability get    \
    --compartment-id ${tenancy_ocid}    \
    --service-name "vcn"                \
    --limit-name "vcn-count"

The sample output is:

{
  "data": {
    "available": 1,
    "effective-quota-value": null,
    "fractional-availability": 1.0,
    "fractional-usage": 1.0,
    "used": 1
  }
}
