Software container messaging mechanism

A system comprising:

• one or more hardware processors;
• and
• a memory storing instructions that, when executed by at least one of the one or more hardware processors, cause the system to perform operations comprising:
• subscribing to a first messaging topic and a data topic at a messaging broker executing on a computing system by a first messaging client executing on the computing system, the subscribing to the first messaging topic and the data topic comprising providing identifiers corresponding to the first messaging client;
• publishing a first message for the messaging topic and a second message for the data topic to the messaging broker by a second messaging client executing on the computing system;
• and
• forwarding the first published message and the published second message by the messaging broker to the first messaging client based on the subscribing to the first messaging topic and the data topic by the first messaging client, wherein each of at least one of the first messaging client and the second messaging client executes in a corresponding software container in the computing system;
• wherein the first messaging client executes in a first software container in the computing system and wherein an application executes in the first software container in the computing system;
• wherein the second messaging client executes in a second software container separate from the first software container in the computing system;
• wherein a third messaging client, an ingress data service, and a device agent are provided by a device services at the computing system, the device services being separate from the first container and the second container, the third messaging client communicating with the messaging broker;
• where the first message comprises a command that is received by the device agent from a cloud computing system over a communication network and the command is processed by the application that is executing in the first software container;
• wherein the second message comprises sensor data that is captured by the ingress data service;
• wherein the messaging broker is configured to trust the first messaging client, the second messaging client, and the third messaging client, but not to trust any other messaging clients that attempt to subscribe.

A non-transitory computer-readable storage medium storing instructions that, when executed by at least one hardware processor of a machine, cause the machine to perform operations comprising:

• subscribing to a first messaging topic and a data topic at a messaging broker executing on a computing system by a first messaging client executing on the computing system, the subscribing to the first messaging topic and the data topic comprising providing identifiers corresponding to the first messaging client;
• publishing a first message for the messaging topic and a second message for the data topic to the messaging broker by a second messaging client executing on the computing system;
• and
• forwarding the first published message and the published second message by the messaging broker to the first messaging client based on the subscribing to the first messaging topic and the data topic by the first messaging client, wherein each of at least one of the first messaging client and the second messaging client executes in a corresponding software container in the computing system;
• wherein the first messaging client executes in a first software container in the computing system and wherein an application executes in the first software container in the computing system;
• wherein the second messaging client executes in a second software container separate from the first software container in the computing system;
• wherein a third messaging client, an ingress data service, and a device agent are provided by a device services at the computing system, the device services being separate from the first container and the second container, the third messaging client communicating with the messaging broker;
• wherein the first message comprises a command that is received by the device agent from a cloud computing system over a communication network and the command is processed by the application that is executing in the first software container;
• wherein the second message comprises sensor data that is captured by the ingress data service;
• wherein the messaging broker is configured to trust the first messaging client, the second messaging client, and the third messaging client, but not to trust any other messaging clients that attempt to subscribe.
