One of the challenges of being a consultant is having to work with a number of clients, and having different login credentials and accounts. In the early days of Azure, this was exceptionally painful, but over time the experience of using the portal with multiple identities and connecting to Azure tenants has gotten much easier. However, when writing PowerShell or Azure CLI code, switching accounts and contexts is slightly more painful. Also, when you are doing automation, you may be touching a lot of resources at one time, you want to be extra careful that you are in the right subscription and tenant.
Enter cloud shell.
If you click on the highlighted icon from the Azure Portal, you will launch cloud shell. This will require you to have an Azure Storage account which will consume a small amount of resources (€$£)–don’t sweat this–it’s literally going to cost pennies per month, unless you decided to upload terabytes of images to your cloud shell (don’t do this). The storage is there so you can maintain a history of commands and even store script files there.
With cloud shell you are automatically logged into the tenant associated with your login–you will still need to select the subscription. As shown below–you can see the subscriptions available to your login.
The other cool thing about cloud shell is that you also have built-in text editors including vim and code. While means you can paste code into a text editor and save it in your shell. Since you have a storage account that data is persisted. So you can have a bunch of scripts saved in your cloud shell. This is great for developing for Azure automation, or just running some ad-hoc scripts.
You can also go full screen with code–as shown above. While all of the examples I’ve shown have been PowerShell, you can also launch a bash shell running the Azure CLI.
