You must set the unique ID of the Datacenter, the unique ID of the LAN, and IP and subnet. If the other options are not set, the default values will be used. Regarding the location field, if it is not manually set, it will be used the location of the Datacenter. Required values to run command: * Datacenter Id * Lan Id * CIDR (IP and subnet) * Credentials for the database user: Username and Password ## Options ``` -u, --api-url string Override default host URL. Preferred over the config file override 'psql' and env var 'IONOS_API_URL' (default "https://api.ionos.com/databases/postgresql") --backup-id string The unique ID of the backup you want to restore --backup-location string The S3 location where the backups will be stored -C, --cidr string The IP and subnet for the cluster. Note the following unavailable IP ranges: 10.233.64.0/18, 10.233.0.0/18, 10.233.114.0/24. e.g.: 192.168.1.100/24 (required) --cols strings Set of columns to be printed on output Available columns: [ClusterId DisplayName Location DatacenterId LanId Cidr Instances State PostgresVersion RAM Cores StorageSize StorageType MaintenanceWindow SynchronizationMode BackupLocation] -c, --config string Configuration file used for authentication (default "$XDG_CONFIG_HOME/ionosctl/config.yaml") --cores int The number of CPU cores per instance. Minimum: 1 (default 2) --datacenter-id string The unique ID of the Datacenter to connect to your cluster (required) --db-password string Password for the initial postgres user (required) --db-username string Username for the initial postgres user. Some system usernames are restricted (e.g. postgres, admin, standby) (required) -D, --depth int Level of detail for response objects (default 1) -F, --filters strings Limit results to results containing the specified filter:KEY1=VALUE1,KEY2=VALUE2 -f, --force Force command to execute without user input -h, --help Print usage --instances int The number of instances in your cluster (one master and n-1 standbys). Minimum: 1. Maximum: 5 (default 1) -L, --lan-id string The unique ID of the LAN to connect your cluster to (required) --limit int Maximum number of items to return per request (default 50) --location string The physical location where the cluster will be created. It cannot be modified after datacenter creation. If not set, it will be used Datacenter's location --maintenance-day string Day Of the Week for the MaintenanceWindows. The MaintenanceWindow is a weekly 4 hour-long windows, during which maintenance might occur --maintenance-time string Time for the MaintenanceWindows. The MaintenanceWindow is a weekly 4 hour-long windows, during which maintenance might occur. e.g.: 16:30:59 -n, --name string The friendly name of your cluster (default "UnnamedCluster") --no-headers Don't print table headers when table output is used --offset int Number of items to skip before starting to collect the results --order-by string Property to order the results by -o, --output string Desired output format [text|json|api-json] (default "text") --query string JMESPath query string to filter the output -q, --quiet Quiet output --ram string The amount of memory per instance. Size must be specified in multiples of 1024. The default unit is MB. Minimum: 4GB. e.g. --ram 4096, --ram 4096MB, --ram 4GB (default "4GB") --recovery-time string If this value is supplied as ISO 8601 timestamp, the backup will be replayed up until the given timestamp. If empty, the backup will be applied completely --storage-size string The amount of storage per instance. The default unit is MB. e.g.: --size 20480 or --size 20480MB or --size 20GB (default "20GB") --storage-type string The storage type used in your cluster: HDD, SSD, SSD_PREMIUM, SSD_STANDARD. (Value "SSD" is deprecated. Use the equivalent "SSD_PREMIUM" instead) (default "HDD") -S, --sync string Synchronization Mode. Represents different modes of replication (default "ASYNCHRONOUS") -t, --timeout int Timeout in seconds for --wait and other wait operations (default 600) -v, --verbose count Increase verbosity level [-v, -vv, -vvv] --version string The PostgreSQL version of your Cluster (default "15") -w, --wait Wait for the resource to reach AVAILABLE state after the command completes. No-op for list commands ``` ## Examples ``` ionosctl dbaas postgres cluster create --datacenter-id DATACENTER_ID --lan-id LAN_ID --cidr CIDR --db-username DB_USERNAME --db-password DB_PASSWORD ionosctl dbaas postgres cluster create -D DATACENTER_ID -L LAN_ID -C CIDR -U DB_USERNAME -P DB_PASSWORD ``` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.ionos.com/cloud/cli/subcommands/database-as-a-service/postgres/cluster/create.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
