Abstract

Methods, systems, and computer program products are included for deploying a composite application. A method includes receiving, at a computing device, a container image that includes a nulecule. The nulecule is parsed to identify a first service, a second service, and a parameter of the first service. An input value is received corresponding to the parameter of the first service. A configuration value of the first service is modified to include the input value. The first service and the second service are deployed on the computing device, with the first service being configured with the configuration value.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving, at a computing device, a container image that includes at least one application, a nulecule file that defines at least one service corresponding to the at least one application, and one or more other files corresponding to the at least one service;
parsing the nulecule file according to a nulecule specification to identify a first service, a second service, a parameter corresponding to the first service, and a first unique identifier that references a first container image that is stored in a container registry, and an artifact for processing the at least one application, wherein the nulecule specification provides additional configuration information for processing the first service by passing a configuration file corresponding to the first service to the artifact, wherein the nulecule specification defines preconfigured keywords to be used during the parsing;
requesting, from the container registry, the first container image corresponding to the first service and a second container image corresponding to the second service;
receiving the first container image and the second container image from the container registry, wherein the container registry stores the first container image and the second container image;
presenting the parameter to a user, the user selecting or updating an input value for the parameter;
receiving the input value corresponding to the parameter;
modifying a configuration value in the configuration file corresponding to the first service to include the input value;
deploying the first service by instantiating the first container image on the computing device; and
deploying the second service by instantiating the second container image on the computing device.

2. The method of claim 1 , wherein the first container image includes a first application corresponding to the first service, and wherein the second container image includes a second application corresponding to the second service.

3. The method of claim 1 , wherein parsing the nulecule file to identify the first service and the second service includes:
parsing a second unique identifier that references the second container image that is stored in the container registry.

4. The method of claim 1 , the method further comprising:
parsing a runtime order corresponding to the first service and the second service, wherein the runtime order specifies that the second service is to be deployed prior to the first service; and
deploying the first service and the second service in the runtime order.

5. The method of claim 1 , wherein the second service is a dependency of the first service.

6. The method of claim 1 , wherein the input value includes one or more of:
network location information and login credential information.

7. The method of claim 1 , the method further comprising:
specifying, in the nulecule file, information corresponding to the first service, the second service, and the parameter;
packaging the nulecule file in the container image; and
sending the container image to the container registry.

8. The method of claim 1 , the method further comprising:
querying, by the computing device, the container registry for the first container image corresponding to the first service; and
sending the first container image from the container registry to the computing device.

9. A non-transitory computer-readable medium, comprising computer-readable instructions executable by a processor to cause the processor to:
receive a container image that includes at least one application, a nulecule that defines at least one service corresponding to the at least one application, and one or more other files corresponding to the at least one service;
parse the nulecule according to a nulecule specification to identify a first service, a second service, parameter of the first service, and a first unique identifier that references a first container image that is stored in a container registry, and an artifact for processing the at least one application, wherein the nulecule specification provides additional configuration information for processing the first service by passing a configuration file corresponding to the first service to the artifact wherein the nulecule specification defines preconfigured keywords to be used during the parsing;
request, from the container registry, the first container image and a second container image;
receive the first container image and the second container image from the container registry, wherein the container registry stores the first container image and the second container image;
present the parameter to a user, the user selecting or updating an input value for the parameter;
receive the input value corresponding to the parameter;
modify a configuration value in the configuration file of the first service to include the input value; and
deploy the first service and the second service, wherein the deployed first service is configured with the configuration value.

10. The medium of claim 9 , wherein the first service interacts with the second service.

11. The medium of claim 10 , the instructions further executable by the processor to cause the processor to:
parse a runtime order corresponding to the first service and the second service, wherein the runtime order specifies that the second service is to be deployed prior to the first service; and
deploy the first service and the second service according to the runtime order.

12. The medium of claim 10 , wherein the second service is a dependency of the first service.

13. The medium of claim 9 , the instructions further executable by the processor to cause the processor to:
parse the nulecule to identify a second unique identifier that references the second container image that is stored in the container registry.

14. The medium of claim 9 , wherein the input value includes at least one information selected from the group consisting of: a network location information and a login credential information.

15. A computer-implemented method comprising:
receiving, at a computing device, a container image that includes at least one application, a nulecule file that defines at least one service corresponding to the at least one application, and one or more other files corresponding to the at least one service;
parsing the nulecule file according to a nulecule specification to identify a first service, a second service, a parameter corresponding to the first service, and a first unique identifier that references a first container image that is stored in a container registry, and an artifact for processing the at least one application, wherein the nulecule specification provides additional configuration information for processing the first service by passing a configuration file corresponding to the first service to the artifact, wherein the nulecule specification defines preconfigured keywords to be used during the parsing;
requesting, from the container registry, the first container image corresponding to the first service and a second container image corresponding to the second service;
receiving the first container image and the second container image from the container registry, wherein the container registry stores the first container image and the second container image;
presenting the parameter to a user, the user selecting or updating an input value for the parameter;
receiving the input value corresponding to the parameter;
modifying a configuration value in the configuration file corresponding to the first service to include the input value.
