Abstract

Systems and methods are described for bootstrapping an application with metadata specified in a template. The template specifies a stack of resources that will be used to execute an application and also includes a set of metadata for customizing the resources and the application. When the system receives the template, it instantiates a compute node which will execute the application. The compute node may contain at least one initialization script for bootstrapping the application with the metadata contained in the template. This functionality allows users to bootstrap the application running on the compute node with data from within the template that was used to create the stack of resources for executing the application. In this manner, metadata, configuration files, package names and versions can be passed by the application owner to the remote compute node.

Claims

1. A computer implemented method for bootstrapping servers, said method comprising:

under control of one or more computer systems configured with executable instructions,

parsing, within a service provider network of a service provider, a template received from a client of the service provider, the service provider providing the service provider network comprising a plurality of network resources for implementing respective applications for a plurality of clients external to the service provider network, the template comprising;

a definition of a stack of resources within the service provider network to execute an application for which the client providing the template is an application owner, and

a set of metadata associated with the stack of resources, the stack of resources including at least one compute node of the service provider network, wherein the set of metadata in the template indicates self-configuration information for the application;

instantiating, by the service provider and based on the definition of the stack of resources from the template, the at least one compute node that will execute at least part of the application; and

using one or more initialization scripts to bootstrap the at least part of the application with the metadata from the template, wherein said using the one or more initialization scripts includes;

loading the one or more initialization scripts onto the at least one compute node, and

executing the one or more initialization scripts on the at least one compute node to bootstrap the at least a part of the application on the at least one compute node according to at least part of the set of metadata contained in the template, wherein at least some portion of the application self-configures in accordance with the set of metadata from the template.

2. The computer implemented method of claim 1, wherein the compute node further includes an operating system and a set of files that are preinstalled on the at least one compute node.

3. The computer implemented method of claim 1, wherein the set of metadata specifies actions that are performed on the at least one compute node at boot time to customize attributes of the application loaded onto the compute node.

4. The computer implemented method of claim 1, wherein the set of metadata instructs the at least one compute node to stop and restart the application.

5. The computer implemented method of claim 1, wherein the at least one compute node further includes a second initialization script, wherein the second initialization script starts a daemon process running on the at least one compute node that periodically checks for changes in resource metadata and triggers execution of a hook in response to detecting a predefined change, the hook including an action specified in the template.

6. A computer implemented method for bootstrapping software, said method comprising:

under control of one or more computer systems configured with executable instructions,

receiving, by a service provider, a template from a client of the service provider, the service provider providing a service provider network comprising a plurality of network resources for implementing respective applications for a plurality of clients external to the service provider network, the template comprising;

a definition of a stack of resources within the service provider network to execute an application for which the client providing the template is an application owner, and

a set of metadata that indicates self-configuration information for the application;

creating, by the service provider and based on the definition of the stack of resources from the template, at least one compute node that will execute at least a portion of the application at a remote location; and

bootstrapping the application on the compute node with the set of metadata contained in the template, wherein at least some portion of the application self-configures in accordance with the set of metadata from the template.

7. The computer implemented method of claim 6, wherein the at least one compute node further includes an initialization script that is executed to bootstrap the application.

8. The computer implemented method of claim 6, wherein the at least one compute node further includes an operating system and a set of files that are preinstalled on the compute node.

9. The computer implemented method of claim 6, wherein the set of metadata specifies actions that are performed on the at least one compute node at boot time to customize attributes of the application.

10. The computer implemented method of claim 6, wherein the set of metadata instructs the at least one compute node to stop and restart the application.

11. The computer implemented method of claim 6, further comprising:

executing, on the at least one compute node, a background process that detects a condition and triggers a user-defined action in response to the condition, the user-defined action being specified in the template.

12. A computing device including a storage memory containing instructions and one or more hardware processors that execute the instructions to implement a network accessible service provider system configured to:

read a template received from a client of a service provider, wherein the service provider provides a service provider network comprising a plurality of network resources for implementation of respective applications for a plurality of clients external to the service provider network,

wherein the template specifies a stack of resources within the service provider network that are instantiated in order to execute an application, and

wherein the template includes a set of metadata that indicates self-configuration information for the application;

create, based on the template, at least one compute node that will execute at least part of the application; and

bootstrap the application on the at least one compute node with the set of metadata that was retrieved by reading the template, wherein at least some portion of the application self-configures in accordance with the set of metadata from the template.

13. The computing device of claim 12, wherein the at least one compute node further includes an initialization script that is executed to bootstrap the application.

14. The computing device of claim 13, wherein the at least one compute node includes an operating system and a set of files that are preinstalled on the compute node.

17. The computing device of claim 12, wherein the network accessible service provider system is further configured to execute, on the at least one compute node, a background process that detects a condition and triggers a user-defined action in response to the condition, the user-defined action being specified in the template.

18. A non-transitory computer readable storage medium storing one or more sequences of instructions that are executed by one or more processors to implement a network accessible service provider system configured to:

receive a template from a client of a service provider, wherein the service provider provides a service provider network comprising a plurality of network resources for implementation of respective applications for a plurality of clients external to the service provider network, wherein the template comprises;
