The goal of this section is to deploy a container to the Mesh environment in Azure and access the application running in Azure.
In this exercise, you will complete the following steps
- Install the Azure Mesh CLI
- Create a resource group for your application
- Deploy a prepackaged container using an ARM template which contains the application
- Access the application
| Step | Action | Result |
|---|---|---|
| 1 | Open Azure cloud shell (https://shell.azure.com) | |
| 2 | run az extension add --name mesh to add the Mesh extension to Azure CLI |
In the terminal, you will see details of the subscription such as the name and id in json format |
| 3 | Create a resource group az group create --name meshAppRg --location eastus |
The newly created resource group details will appear in the terminal with "provisioningState" : "Succeeded" |
| 4 | Deploy the application with the following command az mesh deployment create --resource-group meshAppRg --template-uri https://sfmeshsamples.blob.core.windows.net/templates/helloworld/mesh_rp.linux.json Enter eastus, westus or westeurope when prompted for a location |
The terminal will indicate the application is deploying. Once successfully finished, it will display the IP address to access the application |
| 5 | Navigate to the IP address from the step above in your browser | You will see the webpage from the image at the top of this exercise with the Mesh logo |
| 6 | Run the show command to view more information about your Mesh application. This application's name is helloWorldApp az mesh app show --resource-group meshAppRg --name helloWorldApp |
Additional information about your application will appear including the services, status, description, resourceId etc. |
| 7 | Open http://portal.azure.com and navigate the resource group and Mesh service |
|
| 8 | Keep navigating through the service, replica and finally the `helloWorldCode' Code Package. Here you can see the logs emitted by the container to stdout | Services in Mesh can have multiple code packages, which are always deployed together and share ip |
| 9 | Let's scale up the service, by adding another replica, let's start with downloading the WRM template: curl -o mesh_rp.linux.json https://sfmeshsamples.blob.core.windows.net/templates/helloworld/mesh_rp.linux.json |
This will save the file to the cloud shell storage |
| 10 | Open the file in VS Code, in cloud shell code mesh_rp.linux.json |
|
| 11 | In line 80, change the replicaCount to 2 |
This is the number of replicas of a service you want to run. Remember at this services features two code packages, the consumption will be twice the sum of the code package resources defined. |
| 12 | Save the file and close the editor ctrl + s, ctrl + q | There a small ellipse icon in the top right corner to get to the menu |
| 13 | Let's update the deployment by running az mesh deployment create --resource-group meshAppRg --template-file mesh_rp.linux.json |
ARM uses incremental deployment per default, so only changes will be applied to the deployment |
| 14 | Head over to the Azure Portal to see a second replica of he service now running |
To clean up simple delete the resource group az group delete --name meshAppRG -y this will delete without confirmation.
This concludes you first experience with Mesh - congratulations!
