Create and develop images

Is WALinuxAgent option required when creating images?Can I use WALinuxAgent to develop my own VM operating system?

Yes, this option is required. Otherwise, it is not possible to successfully deploy the images you create. The WALinuxAgent source code is currently open source (source code address), so you can custom-develop WALinuxAgent for your own servers.

What does Azure Linux Agent do?Do I need to install it when I create a VM?

You must select Install WALinuxAgent during the process of creating Linux VMs on the Azure platform.For more information, see the relevant technical documentation, specifically the Azure Linux Agent user guide

I need to need to copy four wallet files from the website to four servers when I am deploying a VM. How can I do this?

You can use the Resource Manager method, which uses the Resource Manager extensions function to copy the wallet files to the servers when the systems start up.

How does the Resource Manager file obtain the server IP address details and write them into the system startup configuration files?

Resource Manager does not support dynamically obtaining IP information, but you can use the Resource Manager extensions function to write the IP address into the configuration files when the system starts up.

You can also set a static IP address.

After I finish deploying an image to Azure, how do I run the commands to start up the deployed system?

The image’s operating system automatically starts up after the image is deployed to Azure, but sometimes you might need to wait a few minutes for the system to fully start up before you can sign in.

I am publishing an image on Azure to Azure Marketplace. How do I set the properties of the Blob where the image is located?

When a 1RMB account expires, can I copy the resources in it to another account?

No, you cannot copy the resource in a 1RMB account to another account when it expires, but you can apply and pay to upgrade to a standard account.

Do I need to pay to upgrade a 1RMB account?

1RMB accounts have certain limitations in terms of credit amounts and time. If the balance on your 1RMB account is insufficient, you need to renew payment to finish publishing; if your balance is insufficient or your account expires, the account may be deleted. We therefore recommend that you upgrade the 1RMB account to safeguard your image update and testing requirements. Details of the 1RMB trial account subscription.

After an application service has been installed and deployed on a VM, how can I publish the service to Azure Marketplace?

Sign in to your Azure account and finish creating the image, and then sign in to Azure Marketplace to publish your image. For more information, please refer to the Azure Image Creation Guide and Publish VM images.

Do I need to enter a detailed description at the image testing stage? Do I need to upload a user manual? If I need to make modifications, are there any examples to use for reference?

You can fill in the detailed description at the testing stage, but you can also fill it in after the image has been successfully tested. It is up to the service provider to decide whether to upload a user manual, but as a general principle, the more detailed your product documentation is, the better. For more information about entering and modifying detailed product information, see products already published on Azure Marketplace. For specific standards, please refer to the “VM content standards” in Publish VM images.

How can you tell whether an image is a Resource Manager template or an image?

The Platform field for all images displays ARM, and you can find all Resource Manager templates by searching for ARM on the Azure Marketplace page.

When I publish to Azure Marketplace, can I post the image’s VHD address or Resource Manager template URL outside Azure?

Image VHD addresses must be posted on Azure. Resource Manager template URLs can be posted outside Azure (on GitHub, for example).

Can locally-created images be uploaded directly to Azure and published to Azure Marketplace?

Yes, but we recommend that you test your image locally first. The more complicated the process for creating images locally, the greater the chance of making errors.

If we want to update a Resource Manager template, do we need to republish an app, or can we use the “Publish new version” function in the old app management interface?

You can use the “Publish new version” function. Note that the URL of the new version of the Resource Manager template must be different from that of the original version. Otherwise, the new version will be invalid.
