Only the flags you pass are changed; everything else is left untouched. The cluster must be in state AVAILABLE for the update to be accepted. Some changes are one-directional and cannot be reverted: * \--version can only be upgraded (10.6 -> 10.11), never downgraded. * \--instances can only be increased, and must stay odd (1 -> 3 -> 5). * \--storage-size can only be increased, never shrunk. * \--cores and --ram can be scaled up or down. \--maintenance-day and --maintenance-time must be supplied together (a maintenance window has both a day and a start time). The connection (datacenter/LAN/CIDR) and initial credentials are set at creation and cannot be changed here. ## Options ``` -u, --api-url string Override default host URL. If contains placeholder, location will be embedded. Preferred over the config file override 'mariadb' and env var 'IONOS_API_URL' (default "https://mariadb.%s.ionos.com") -i, --cluster-id string The unique ID of the cluster to update. Must be in state AVAILABLE (required) --cols strings Set of columns to be printed on output Available columns: [ClusterId Name DNS Instances Version State Cores RAM StorageSize MaintenanceDay MaintenanceTime] -c, --config string Configuration file used for authentication (default "$XDG_CONFIG_HOME/ionosctl/config.yaml") --cores int32 New CPU core count per instance (minimum 1). Can be scaled up or down -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 int32 New instance count (primary + secondaries). Can only be increased and must stay odd: 1, 3 or 5. Adding instances converts a standalone cluster into a high-availability replica set --limit int Maximum number of items to return per request (default 50) -l, --location string Location of the resource to operate on. When unset, list commands query all locations. Can be one of: de/txl, de/fra, es/vit, fr/par, gb/lhr, us/ewr, us/las, us/mci. A facility inside one of these metro regions (e.g. de/fra/1) is also accepted and served by its metro region's endpoint --maintenance-day string New day of the week for the weekly maintenance window, e.g. Monday. Must be supplied together with --maintenance-time --maintenance-time string New start time (UTC, HH:MM:SS, e.g. 16:30:59) of the weekly 4-hour maintenance window. Must be supplied together with --maintenance-day -n, --name string New human-friendly display name for the cluster (max 63 characters) --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 New memory per instance, e.g. --ram 8GB. Minimum 4GB, whole GB only. Can be scaled up or down --storage-size string New storage per instance, e.g. --storage-size 200GB. Can only be increased (never shrunk), up to 2000GB (2TB) -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 Upgrade the MariaDB version (one of: 10.6, 10.11). Upgrade only; downgrades are rejected by the API -w, --wait Wait for the resource to reach AVAILABLE state after the command completes. No-op for list commands ``` ## Examples ``` # Upgrade the MariaDB version ionosctl dbaas mariadb cluster update --cluster-id --version 10.11 # Scale compute and move the maintenance window (day and time must be given together) ionosctl dbaas mariadb cluster update --cluster-id --cores 8 --ram 32GB --storage-size 200GB --maintenance-day Saturday --maintenance-time 02:00:00 ``` --- # 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/tools-cli/subcommands/database-as-a-service/mariadb/cluster/update.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.
