hostName^Optional

public readonly hostName: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property hostName: Host name of created ecs instance.

at least 2 characters, and '.' '-' Is not the first and last characters as hostname, not continuous use. Windows platform can be up to 15 characters, allowing letters (without limiting case), numbers and '-', and does not support the number of points, not all is digital ('.').Other (Linux, etc.) platform up to 64 characters, allowing support number multiple points for the period between the points, each permit letters (without limiting case), numbers and '-' components. Support to use the regular expression to set the different instance name for each ECS instance. HostName could be specified as 'name_prefix[begin_number,bits]name_suffix', such as 'host[123,4]tail'. If you creates 3 instances with hostname 'host[123,4]tail', all the host names of instances are host0123tail, host0124tail, host0125tail. The 'name_prefix[begin_number,bits]name_suffix' should follow those rules: 1. 'name_prefix' is required. 2. 'name_suffix' is optional. 3. The name regular expression can't include any spaces. 4. The 'bits' must be in range [1, 6]. 5. The 'begin_number' must be in range [0, 999999]. 6. You could only specify 'begin_number'. The 'bits' will be set as 6 by default. 7. You also could only specify the [] or [,]. The 'begin_number' will be set as 0 by default, the 'bits' will be set as 6 by default. 8. If the bits of 'begin_number' is less than the 'bits' you specified, like [1234,1], the 'bits' will be set as 6 by default. The host name is specified by regular expression works after restart instance manually.

Examples: HostNames.1=test1 and HostNames.2=test2. - You cannot specify both HostName and HostNames.N. - The hostname cannot start or end with a period (.) or hyphen (-). The hostname cannot contain consecutive periods (.) or hyphens (-). - For Windows instances, the hostname must be 2 to 15 characters in length and cannot contain periods (.) or contain only digits. The hostname can contain letters, digits, and hyphens (-). - For instances that run other operating systems such as Linux, the hostname must be 2 to 64 characters in length.
