Abstract

An application instance staging method comprises installing a runtime environment for an application program pushed to a cloud client; installing dependency of the application program; reading an environment variable of the application program to identify a functional service bound to the application program; modifying the application program based on the functional service bound to the application program; and packaging the modified application program, runtime environment, and dependency into an executable droplet.

Claims

1. A method of application instance staging, the method comprising:

installing a runtime environment for an application program pushed to a cloud client;

installing dependency of the application program;

reading an environment variable of the application program to identify a functional service bound to the application program;

modifying the application program based on the functional service bound to the application program; and

packaging the modified application program, runtime environment, and dependency into an executable droplet.

2. The method of claim 1, wherein modifying the application program includes at least one of:

modifying code of the application program according to requirements of the functional service;

installing a service support artifact to the application program according to requirements of the functional service; and

setting an environment variable of the application program according to requirements of the functional service.

3. The method of claim 1, further comprising:

converting a generic buildpack of a cloud computing platform into a buildpack corresponding to the functional service by installing a plugin corresponding to the functional service in the generic buildpack of the cloud computing platform.

4. The method of claim 3, further comprising:

receiving the plugin uploaded to the cloud computing platform; and

registering the uploaded plugin to the generic buildpack of the cloud computing platform.

5. The method of claim 3, further comprising one of:

invoking the plugin by the generic buildpack; and

parsing the plugin by the generic buildpack.

6. The method of claim 1, further comprising:

verifying that one or more conditions for modifying the application program corresponding to the functional service have been met prior to modifying the application program.

12. The apparatus of claim 6, wherein the processing unit is further configured to verify that one or more conditions for modifying the application program have been met prior to modifying the application program, the one or more conditions corresponding to the functional service.

7. An application instance staging apparatus, comprising:

an interface configured to receive a user application program over a network;

a memory; and

a processing unit coupled to the interface and to the memory;

wherein the processing unit is configured to install a runtime environment for the user application program, install dependency of the user application program, read an environment variable of the user application program to identify a functional service bound to the user application program, and modify the user application program based on the functional service bound to the application program;

wherein the processing unit is further configured to package the modified user application program, runtime environment and dependency into an executable droplet, and to store the executable droplet in the memory.

8. The apparatus of claim 7, wherein the processing unit is configured to modify the user application program based on the functional service by:

modifying code of the application program according to requirements of the functional service;

installing a service support artifact to the application program according to requirements of the functional service;

or

setting an environment variable of the application program according to requirements of the functional service.

9. The apparatus of claim 7, wherein processing unit is further configured to install a plugin corresponding to the functional service to a generic buildpack of a cloud computing platform to convert the generic buildpack into a buildpack corresponding to the functional service.

10. The apparatus of claim 9, wherein interface is configured to receive the plugin over the network and the processing unit is configured to register the plugin to the generic buildpack.

11. The apparatus of claim 9, wherein the plugin comprises any one of:

a plugin capable of being invoked by the generic buildpack; and

a plugin capable of being parsed by the generic buildpack.

13. A program product comprising a processor-readable storage medium having program instructions embodied thereon, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to:

install a runtime environment for an application program pushed to a cloud client by a user;

install dependency of the application program;

read an environment variable of the application program to identify a functional service bound to the application program by the user;

modify the application program based on the functional service bound to the application program; and

package the modified application program, runtime environment, and dependency into an executable droplet.

14. The program product of claim 13, wherein the program instructions further cause the processor to modify the application program by performing at least one of:

modifying code of the application program according to requirements of the functional service;

installing a service support artifact to the application program according to requirements of the functional service; and

setting an environment variable of the application program according to requirements of the functional service.

15. The program product of claim 13, wherein the program instructions further cause the processor to convert a generic buildpack of a cloud computing platform into a buildpack corresponding to the functional service by installing a plugin corresponding to the functional service in the generic buildpack of the cloud computing platform, the plugin provided by a service provider.

16. The program product of claim 15, wherein the program instructions further cause the processor to receive the plugin over a network connection and to register the plugin to the generic buildpack.

17. The program product of claim 15, wherein the program instructions further cause the processor to invoke the plugin or parse the plugin.

18. The program product of claim 13, wherein the program instructions further cause the processor to verify that one or more conditions corresponding to the functional service for modifying the application program have been met prior to modifying the application program.
