These snippets allow creating a service bus namespace, write sample messages to it and read them

These snippets require a linux environment, python3, Azure Service Bus python SDK and Azure CLI installed. If you have those already installed, go to the next section. For installing the Azure az CLI, please refer to the Azure Documentation.
Additionally, you would need to install additional packages with the following snippet:

sudo apt-get update -y
sudo apt-get install python3-pip -y
pip3 install azure-servicebus

Once installed, perform account login using az login

You can use the scripts provided for writing and reading from an existing service bus and topic, but the following script would create a test environment. You need to provide the subscription id as parameter and have executed previously az login to this very subscription.

 ./0_create_service_bus.sh 11111111-2222-3333-4444-55555555555 
Subscription set to 11111111-2222-3333-4444-55555555555
Creating RG service-bus-demo-rg in region westeurope
{
  "id": "/subscriptions/11111111-2222-3333-4444-55555555555/resourceGroups/service-bus-demo-rg",
  "location": "westeurope",
  "managedBy": null,
  "name": "service-bus-demo-rg",
  "properties": {
    "provisioningState": "Succeeded"
    .......

If you have created the environment with the script 0_create_service_bus.sh, the message delivery script does not need additional parameters.

 ./1_service_bus_sender.sh  
Initialized connection to service bus service-bus-demo-sb-namespace on topic service-bus-demo-sb-topic at 2020-04-10 15:59:42.774624
  Sending message b'Msg 0 at 2020-04-10 15:59:42.774983' 
  Sending message b'Msg 1 at 2020-04-10 15:59:48.323102' 
  Sending message b'Msg 2 at 2020-04-10 15:59:48.430927' 
  Sending message b'Msg 3 at 2020-04-10 15:59:48.539948' 
  Sending message b'Msg 4 at 2020-04-10 15:59:48.648204' 

Additionally it can send sample messages to any service bus topic overriding default parameters, such as resource group, service bus namespace name and key.

./1_service_bus_sender.sh -h  
Usage: cmd [-n service_bus_namespace_name] [-g resource_group] [-k key_value] [-t topic]

If you have created the environment with the script 0_create_service_bus.sh, the script for receiving messages does not need additional parameters.

  ./2_service_bus_receiver.sh

Additionally it can receive messages to any service bus topic overriding default parameters, such as resource group, service bus namespace name and key.

./2_service_bus_receiver.sh -h 
Usage: cmd [-n service_bus_namespace_name] [-g resource_group] [-k key_value] [-t topic]
