This is a tiny program that allows one to connect to Azure Cloud Shell from within the ordinary Unix terminal, not from the web browser.
You need to get your resource group and storage account ready by opening up Cloud Shell at Azure Portal at least once.
If you've already set up azure CLI, then just type
$ ./az-cloud-shell-access shell
to connect to the cloud shell instance that resides within the tenant of the default subscription.
If you want to use the instance in the different tenant, specify AZURE_TENANT_ID environment variable.
Azure Cloud Shell has built-in HTTP forward proxy support.
$ ./az-cloud-shell-access proxy --port 8092 --local-addr :8080
will instruct Azure Cloud Shell control plane and az-cloud-shell-access to forward HTTP requests to the local address :8080 to the remote address 127.0.0.1:8092.
The remote port must be in range of 1025-8079 and 8091-49151.
Details are taken from windows Terminal's Azure Cloud Shell connector.
