UpdateContainerService - Amazon Lightsail

UpdateContainerService

Updates the configuration of your Amazon Lightsail container service, such as its power, scale, and public domain names.

Request Syntax

{ "isDisabled": boolean, "power": "string", "publicDomainNames": { "string" : [ "string" ] }, "scale": number, "serviceName": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

isDisabled

A Boolean value to indicate whether the container service is disabled.

Type: Boolean

Required: No

power

The power for the container service.

The power specifies the amount of memory, vCPUs, and base monthly cost of each node of the container service. The power and scale of a container service makes up its configured capacity. To determine the monthly price of your container service, multiply the base price of the power with the scale (the number of nodes) of the service.

Use the GetContainerServicePowers action to view the specifications of each power option.

Type: String

Valid Values: nano | micro | small | medium | large | xlarge

Required: No

publicDomainNames

The public domain names to use with the container service, such as example.com and www.example.com.

You can specify up to four public domain names for a container service. The domain names that you specify are used when you create a deployment with a container configured as the public endpoint of your container service.

If you don't specify public domain names, then you can use the default domain of the container service.

Important

You must create and validate an SSL/TLS certificate before you can use public domain names with your container service. Use the CreateCertificate action to create a certificate for the public domain names you want to use with your container service.

You can specify public domain names using a string to array map as shown in the example later on this page.

Type: String to array of strings map

Required: No

scale

The scale for the container service.

The scale specifies the allocated compute nodes of the container service. The power and scale of a container service makes up its configured capacity. To determine the monthly price of your container service, multiply the base price of the power with the scale (the number of nodes) of the service.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 20.

Required: No

serviceName

The name of the container service to update.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 63.

Pattern: ^[a-z0-9]{1,2}|[a-z0-9][a-z0-9-]+[a-z0-9]$

Required: Yes

Examples

In the following example or examples, the Authorization header contents (AUTHPARAMS) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see Signature Version 4 Signing Process in the AWS General Reference.

You need to learn how to sign HTTP requests only if you intend to manually create them. When you use the AWS Command Line Interface (AWS CLI) or one of the AWS SDKs to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

Update container service
