This folder contains Java samples that demonstrate an overview of the
7+
Google Cloud IoT Core platform.
8+
9+
## Quickstart
10+
11+
1. From the [Google Cloud IoT Core section](https://console.cloud.google.com/iot/)
12+
of the Google Cloud console, create a device registry.
13+
2. Use the [`generate_keys.sh`](generate_keys.sh) script to generate your signing keys:
14+
15+
./generate_keys.sh
16+
17+
3. Add a device using the file `rsa_cert.pem`, specifying RS256_X509 and using the
18+
text copy of the public key starting with the ----START---- block of the certificate.
19+
20+
cat rsa_cert.pem
21+
22+
4. Connect a device using the HTTP or MQTT device samples in the [manager](./manager) folder.
23+
24+
5. Programmattically control device configuration and using the device manager sample in the [manager](./manager) folder.

# Cloud IoT Core Commands Java Codelab

This sample app demonstrates device management for Google Cloud IoT Core.
7+
8+
Note that before you can run the sample, you must configure a Google Cloud
9+
PubSub topic for Cloud IoT as described in [the parent README](../README.md).
10+
11+
Before running the samples, you can set the `GOOGLE_CLOUD_PROJECT` and
12+
`GOOGLE_APPLICATION_CREDENTIALS` environment variables to avoid passing them to
13+
the sample every time you run it.
14+
15+
## Setup
16+
Run the following command to install the libraries and build the sample with
17+
Maven:
18+
19+
mvn clean compile assembly:single
20+
21+
## Running the sample
22+
23+
The following description summarizes the sample usage:
24+
25+
usage: MqttCommandsDemo [--cloud_region <arg>] --project_id <arg>
26+
--registry_id <arg> --device_id <arg>
27+
28+
Cloud IoT Core Commandline Example (MQTT Device / Commands codelab):
29+
30+
--cloud_region <arg> GCP cloud region (default us-central1).
31+
--private_key_file <arg> Path to RS256 private key file.
32+
--algorithm <arg> Encryption algorithm to use to generate the JWT.
33+
--project_id <arg> GCP cloud project name.
34+
--registry_id <arg> Name for your Device Registry.
35+
--device_id <arg> ID for your Device.
36+
37+
https://cloud.google.com/iot-core
38+
39+
For example, if your project ID is `blue-jet-123`, your service account
40+
credentials are stored in your home folder in creds.json and you have generated
41+
your credentials using the shell script provided in the parent folder, you can
42+
run the sample as:
43+
44+
# Cloud IoT Core Java MQTT example
45+
46+
This sample app publishes data to Cloud Pub/Sub using the MQTT bridge provided
47+
as part of Google Cloud IoT Core.
48+
49+
Note that before you can run the sample, you must configure a Google Cloud
50+
PubSub topic for Cloud IoT Core and register a device as described in the
51+
[parent README](../README.md).
52+
53+
## Setup
54+
55+
Run the following command to install the dependencies using Maven:
56+
57+
mvn clean compile
58+
59+
## Running the sample
60+
61+
The following command summarizes the sample usage:
62+
63+
mvn exec:java \
64+
-Dexec.mainClass="com.example.cloud.iot.examples.MqttCommandsDemo" \
65+
-Dexec.args="-project_id=my-iot-project \
66+
-registry_id=my-registry \
67+
-cloud_region=us-central1 \
68+
-device_id=my-device \
69+
-private_key_file=rsa_private_pkcs8 \
70+
-algorithm=RS256"
71+
72+
Run mqtt example:
73+
74+
mvn exec:java \
75+
-Dexec.mainClass="com.example.cloud.iot.examples.MqttCommandsDemo" \
76+
-Dexec.args="-project_id=blue-jet-123 \
77+
-registry_id=my-registry \
78+
-cloud_region=asia-east1 \
79+
-device_id=my-device \
80+
-private_key_file=../rsa_private_pkcs8 \
81+
-algorithm=RS256"
