Load Balancer provides a CLI for configuring and managing load balancing features—such as load balancers and target groups—using the `vloadbalancer` command. ## Common Load Balancer (VPC) settings This section covers the command and option formats used across the Load Balancer (VPC) CLI. ### Syntax Run `vloadbalancer` using the following syntax. ``` ./ncloud vloadbalancer [options] ``` ### Options The following options are available across all `vloadbalancer` subcommands: | Options | Type | Required | Description | | --- | --- | --- | --- | | `--regionCode` | String | Optional | Region code - `KR` \| `SGN` \| `JPN` - Default: First Region in the [getRegionList](/docs/en/cli-vserver-server-common-getregionlist) query results (default) | | `--output` | String | Optional | Format of the response result - `json` (default) \| `xml` | ## Load Balancer (VPC) commands The following subcommands are available under `vloadbalancer`. ### Target Group The following describes the target group-related commands: | Commands | Description | | --- | --- | | [createTargetGroup](/docs/en/cli-vloadbalancer-targetgroup-createtargetgroup) | Create a target group. | | [getTargetGroupList](/docs/en/cli-vloadbalancer-targetgroup-gettargetgrouplist) | Get the target group list. | | [getTargetGroupDetail](/docs/en/cli-vloadbalancer-targetgroup-gettargetgroupdetail) | Get target group details. | | [changeTargetGroupConfiguration](/docs/en/cli-vloadbalancer-targetgroup-changetargetgroupconfiguration) | Change target group settings. | | [changeTargetGroupHealthCheckConfiguration](/docs/en/cli-vloadbalancer-targetgroup-changetargetgrouphealthcheckconfiguration) | Change health check settings for a target group. | | [setTargetGroupDescription](/docs/en/cli-vloadbalancer-targetgroup-settargetgroupdescription) | Edit target group description. | | [getTargetList](/docs/en/cli-vloadbalancer-targetgroup-gettargetlist) | Get the list of targets applied to a target group. | | [addTarget](/docs/en/cli-vloadbalancer-targetgroup-addtarget) | Add a target to a target group. | | [setTarget](/docs/en/cli-vloadbalancer-targetgroup-settarget) | Configure a target to be applied for a target group. | | [removeTarget](/docs/en/cli-vloadbalancer-targetgroup-removetarget) | Remove a target applied to a target group. | | [deleteTargetGroups](/docs/en/cli-vloadbalancer-targetgroup-deletetargetgroups) | Delete a target group. | ### Load Balancer The following describes the load balancer-related commands: | Commands | Description | | --- | --- | | [createLoadBalancerInstance](/docs/en/cli-vloadbalancer-loadbalancer-createloadbalancerinstance) | Create a load balancer instance. | | [getLoadBalancerInstanceList](/docs/en/cli-vloadbalancer-loadbalancer-getloadbalancerinstancelist) | Get the load balancer instance list. | | [getLoadBalancerInstanceDetail](/docs/en/cli-vloadbalancer-loadbalancer-getloadbalancerinstancedetail) | Get load balancer instance details. | | [changeLoadBalancerInstanceConfiguration](/docs/en/cli-vloadbalancer-loadbalancer-changeloadbalancerinstanceconfiguration) | Change load balancer instance settings. | | [setLoadBalancerDescription](/docs/en/cli-vloadbalancer-loadbalancer-setloadbalancerdescription) | Edit load balancer description. | | [setLoadBalancerInstanceSubnet](/docs/en/cli-vloadbalancer-loadbalancer-setloadbalancerinstancesubnet) | Configure a subnet for a load balancer. | | [deleteLoadBalancerInstances](/docs/en/cli-vloadbalancer-loadbalancer-deleteloadbalancerinstances) | Delete a load balancer instance. | | [createLoadBalancerListener](/docs/en/cli-vloadbalancer-loadbalancer-createloadbalancerlistener) | Create a new listener on a load balancer. | | [getLoadBalancerListenerList](/docs/en/cli-vloadbalancer-loadbalancer-getloadbalancerlistenerlist) | Get the list of listeners registered on a load balancer. | | [changeLoadBalancerListenerConfiguration](/docs/en/cli-vloadbalancer-loadbalancer-changeloadbalancerlistenerconfiguration) | Change load balancer listener settings. | | [deleteLoadBalancerListeners](/docs/en/cli-vloadbalancer-loadbalancer-deleteloadbalancerlisteners) | Delete a listener registered on a load balancer. | | [addLoadBalancerListenerCertificate](/docs/en/cli-vloadbalancer-loadbalancer-addloadbalancerlistenercertificate) | Add an SNI-based multi-TLS certificate. | | [getLoadBalancerListenerCertificateList](/docs/en/cli-vloadbalancer-loadbalancer-getloadbalancerlistenercertificatelist) | Get the list of TLS certificates for a load balancer listener. | | [removeLoadBalancerListenerCertificate](/docs/en/cli-vloadbalancer-loadbalancer-removeloadbalancerlistenercertificate) | Remove an SNI-based multi-TLS certificate. | | [getLoadBalancerRuleList](/docs/en/cli-vloadbalancer-loadbalancer-getloadbalancerrulelist) | Get the list of rules registered for a load balancer listener. | ## Load Balancer (VPC) related resources These resources provide additional context and support for the Load Balancer (VPC) CLI. -
