When you create an Elastic Compute Service (ECS) instance, you must select an image from a vast collection. You can find images by using the console, the Image Catalog, or API operations.

Find an image on the Custom Launch page

  1. Go to the ECS console - Custom Launch page.

  2. In the Image section, click a tab to quickly select an image, or use the search feature to find a specific image.

    To perform a detailed global search, click the image icon. In the dialog box that appears, you can find an image using the Image Catalog.

  3. Configure the other properties for the ECS instance and follow the on-screen instructions to create the instance.

Find an image on the Images page

On the Images page, you can find purchased Marketplace Images, Custom Images, Shared Images, Community Images, and Public Images.

The Marketplace Images tab displays only the Alibaba Cloud Marketplace Images that you have purchased. To browse and select new images, go to the Alibaba Cloud Marketplace.

  1. Go to the ECS console - Images page. In the upper-left corner, select the target Resource Group and Region.

  2. Select an image type based on your business needs.

    On the Custom Images tab, you can group and view images by image family. If you need to maintain consistent operating system versions, enable the Image Family View.

Find an image using the Image Catalog

The Image Catalog organizes all images by factors such as ownership and usage frequency. It also provides an intelligent search function and granular filtering. The Image Catalog offers more categories and filters than the Images page. You can use the Image Catalog to explore and compare images if you are unsure which one to select.

The Image Catalog marks images that meet ECS image standardization specifications as Standard Images.

Procedure

  1. Go to the ECS console - Image Catalog page. In the upper-left corner of the page, select a resource group and region.

  2. On the Image Catalog page, select an image category to find your target image. In the filter conditions area, you can also select filters to find matching images.

    Quick Launch images are common images that are selected and recommended by Alibaba Cloud. They are sourced from public images and marketplace images. Private images belong to the current user and include custom images created by the user and images shared by other users.

  3. After you search or filter, you can click to view the search results from other categories on the right. This action displays matching images from categories other than the one currently displayed.

Find an image by using the API

You can call the DescribeImages API operation to find Custom Images, Public Images, Marketplace Images, and Shared Images from other Alibaba Cloud accounts.

FAQ

What is a standard image?

A Linux image is defined as a standard image if it meets all the following conditions:

Important

Standard images are not assessed for security vulnerabilities such as Common Vulnerabilities and Exposures (CVEs). Therefore, before you use a recommended image from the Alibaba Cloud platform, you must perform a comprehensive security assessment and vulnerability scan. You must also promptly update and fix any potential security vulnerabilities. Alternatively, you can select images with a higher level of security or take other security measures to protect your systems and data based on your specific needs and security requirements. For more information about the responsibilities associated with images, see the Image Overview page.

  • Alibaba Cloud cloud-init is installed: This is used for instance initialization.

  • The kernel supports the CONFIG_FW_CFG_SYSFS feature: This is used to pass instance metadata.

  • The network is configured for DHCP: This ensures that instances created from the image can automatically obtain IP addresses.

  • The Virtio driver is installed: This provides high-performance I/O.

  • The growpart tool is installed: This supports automatic root partition scale-out when the instance starts.

  • The fstab and grub files are configured using UUIDs: This prevents startup failures caused by changes in disk order.

Why can't I find the image I need in the console?

Check the following items to troubleshoot the issue:

  1. Region: Ensure the Region selected in the console matches the image's location.

  2. Image type: Ensure you are viewing the correct image type tab.

  3. Permission: Confirm that the RAM User or role you are using has the ecs:DescribeImages permission.

  4. Image Status: Make sure the image status is Available.

  5. If it is a Shared Image, confirm the following with the account that shared the image:

    1. The image has been successfully shared with your Alibaba Cloud account.

    2. The image is shared in the same Region that you have selected.

  6. To view Marketplace Images that you have not yet purchased, go to Alibaba Cloud Marketplace.

  7. If the resource was recently created, indexing can take 1 to 5 minutes. Wait a few minutes, then refresh the page.
