## Properties
<a name="aws-properties-lightsail-container-container-properties"></a>

`Command`  <a name="cfn-lightsail-container-container-command"></a>
The launch command for the container.  
*Required*: No  
*Type*: Array of String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ContainerName`  <a name="cfn-lightsail-container-container-containername"></a>
The name of the container.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Environment`  <a name="cfn-lightsail-container-container-environment"></a>
The environment variables of the container.  
*Required*: No  
*Type*: Array of [EnvironmentVariable](aws-properties-lightsail-container-environmentvariable.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Image`  <a name="cfn-lightsail-container-container-image"></a>
The name of the image used for the container.  
Container images that are sourced from (registered and stored on) your container service start with a colon (`:`). For example, if your container service name is `container-service-1`, the container image label is `mystaticsite`, and you want to use the third version (`3`) of the registered container image, then you should specify `:container-service-1.mystaticsite.3`. To use the latest version of a container image, specify `latest` instead of a version number (for example, `:container-service-1.mystaticsite.latest`). Your container service will automatically use the highest numbered version of the registered container image.  
Container images that are sourced from a public registry like Docker Hub don’t start with a colon. For example, `nginx:latest` or `nginx`.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Ports`  <a name="cfn-lightsail-container-container-ports"></a>
An object that describes the open firewall ports and protocols of the container.  
*Required*: No  
*Type*: Array of [PortInfo](aws-properties-lightsail-container-portinfo.md)
