# update

## Usage

```
ionosctl compute applicationloadbalancer update [flags]
```

## Aliases

For `applicationloadbalancer` command:

```
[alb]
```

For `update` command:

```
[u up]
```

## Description

Use this command to update a specified Application Load Balancer from a Virtual Data Center. You can rename it, move which LANs it listens on / balances to, or change its public/private IP set. Only the flags you provide are changed.

Use `--wait` (`-w`) to wait for the resource to reach AVAILABLE state.

Required values to run command:

* Data Center Id
* Application Load Balancer Id

## Options

```
  -u, --api-url string                      Override default host URL. Preferred over the config file override 'cloud' and env var 'IONOS_API_URL' (default "https://api.ionos.com")
  -i, --applicationloadbalancer-id string   The unique ApplicationLoadBalancer Id (required)
      --cols strings                        Set of columns to be printed on output 
                                            Available columns: [ApplicationLoadBalancerId Name ListenerLan Ips TargetLan PrivateIps State DatacenterId]
  -c, --config string                       Configuration file used for authentication (default "$XDG_CONFIG_HOME/ionosctl/config.yaml")
      --datacenter-id string                The unique Data Center Id (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

      --ips strings                         The IP addresses clients use to reach the balancer on the listener LAN. Customer-reserved public IPs for a public ALB, or private IPs for a private ALB. Replaces the existing set.
      --limit int                           Maximum number of items to return per request (default 50)
      --listener-lan int                    Numeric ID of the LAN clients connect to (the inbound/listener LAN).
  -n, --name string                         The name of the Application Load Balancer. (default "Application Load Balancer")
      --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

  -o, --output string                       Desired output format [text|json|api-json] (default "text")
      --private-ips strings                 The balancer's own private IP addresses (with subnet mask) on the target LAN, used to reach the backends, e.g. --private-ips 10.0.1.5/24. If omitted, the system auto-generates an IP with a /24 subnet.
      --query string                        JMESPath query string to filter the output

```

## Examples

```
# Rename an ALB
ionosctl compute applicationloadbalancer update --datacenter-id DATACENTER_ID -i APPLICATIONLOADBALANCER_ID --name "prod-web-alb"

# Replace the public listener IP set
ionosctl compute applicationloadbalancer update --datacenter-id DATACENTER_ID -i APPLICATIONLOADBALANCER_ID --ips 192.0.2.20 --wait

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

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/application-load-balancer/update.md?ask=<question>&goal=<endgoal>
```

`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.
