The following Object Storage providers can be configured as storage backends for your Polaris catalog:

- [S3 compatible object stores]({{< ref "s3.md" >}})
- [Google Cloud Storage]({{< ref "catalog-gcs.md" >}})
- [Azure Blob Storage]({{< ref "catalog-azure.md" >}})
- Local file system (By default for testing only)

Catalogs may also be created from [migrating existing Iceberg catalogs]({{< ref "catalog-migration.md" >}}).

## Create a catalog using polaris CLI

Check full list of options for the `polaris catalogs create` command [here]({{% ref "../../command-line-interface#create" %}})

### Example

```shell
CLIENT_ID=root \
CLIENT_SECRET=s3cr3t \
DEFAULT_BASE_LOCATION=s3://example-bucket/my_data \
ROLE_ARN=arn:aws:iam::111122223333:role/ExampleCorpRole \
./polaris \
  --client-id ${CLIENT_ID} \
  --client-secret ${CLIENT_SECRET} \
  catalogs \
  create \
  --storage-type s3 \
  --default-base-location ${DEFAULT_BASE_LOCATION} \
  --role-arn ${ROLE_ARN} \
