Create Application VM

This topic describes how to create an Application VM in Oracle Data Infrastructure Cloud@Customer.

Prerequisites

Procedure

Perform the following steps in the Console.

  1. On the Data Infrastructures list page, select the Data Infrastructure that you want to work with. If you need help finding the list page or the Data Infrastructure, see List Data Infrastructures.

  2. On the Data Infrastructure details page, select the Application VMs tab to view the list of all Application VMs.

  3. On the Application VMs tab, select Create Application VM.

  4. On the Create Application VM page, provide the following details.

    • Name: Specify a user-friendly name to identify the Application VM. The name must follow these guidelines:

      • Maximum of 255 characters
      • Contains only alphanumeric, underscores, or hyphens
      • Begins with alphabet or underscore character.
      • Must not have consecutive hyphens or a trailing hyphen

    • Create in compartment: Select a compartment.

    • Data Infrastructure: If you begin creating an Application VM from the Data Infrastructure details page, the Data Infrastructure is already selected.

      • Compartment: Select the compartment.

      • Data Infrastructure: Select the Data Infrastructure from the list.

      • Show Infrastructure details: Displays the details of the selected Data Infrastructure.

    • Server:

      • Specify preferred server to create the Application VM: The preferred server controls the initial placement of the Application VM. Select a specific server to place the Application VM on that server when possible, or select Any server to let the Data Infrastructure select an available server.

    • Image and shape:

      • Image: Select from the available Oracle Linux versions.

      • OCPUs: Select the number of OCPUs. Minimum is 1.

      • Total memory for the VM: Select the total memory for the VM. The minimum is 8 GB, and the maximum is 8 GB per OCPU.

    • Storage: Specify storage for Boot and Block volumes attached to your Application VM. VM storage is allocated from the Data storage (+DATA) reserved for VM file systems.

      • Boot volume size: Select the size of the VM’s boot volume in gigabytes (GB). This volume includes the operating system boot partition, the /home directory, and swap space. The minimum size is 50 GB. The maximum depends on the available storage capacity.

      • Block volume size: Select the size of the VM’s block volume in gigabytes (GB). This volume can be used as the additional user volume for your applications within the VM. The minimum size is 1 GB. The maximum depends on the available storage capacity.

    • Network details:

      • Compartment: Select the compartment of the VM Network.

      • Application VM Network: Specify network to be configured on the Application VM. Only a validated Application VM Network can be selected.

      • Add SSH key: Add the public key portion of each key pair you want to use for SSH access. Select one of the following options.

        • Generate SSH key pair: Use this option to create a new SSH key pair. Select both Save private key and Save public key. The private key is downloaded to your local system. Store the private key in a secure location because it isn’t available for download after you complete the workflow.

        • Upload SSH key files: Select this option to browse or drag and drop your existing public key (.pub) files.

        • Paste SSH keys: Select this option to paste in individual public keys. To paste multiple keys, select + Another SSH key and supply a single key for each entry.

    • Advanced options: Expand to provide additional details.

      • Management: Expand to provide additional details.

        • Instance metadata: Provide metadata about the instance. Applications can use this metadata to bootstrap or do other tasks. These key-value pairs can be retrieved and used in cloud-init scripts. Select + Add to add more key-value pairs.

        • Initialization script: You can provide a startup script that runs when your instance starts or restarts. Startup scripts can install software and updates and ensure that services are running within the instance.

          • Choose cloud-init script file: Select this option to select Cloud-init script from the system.

          • Paste cloud-init script: Select this option to paste the Cloud-init script.

      • Tags: Expand Tags to add tag details for this resource. You can add free-form tags or defined tags to this resource. You must have permission to use the tag namespace for defined tags. For more information about using tags to manage your resources, see Tags. Tags can be applied later or at any time to a resource.

      • Time zone: Expand Time Zone to provide time zone details for this resource. The default time zone for the Data Infrastructure is UTC, but you can specify a different time zone. The time zone options are those supported in both the Java.util.TimeZone class and the Oracle Linux operating system. The following options are available:

        • UTC: configures to use coordinated universal time.

        • Browser-detected: The Console displays the time zone detected by your browser for this option.

        • Select another time zone: To manually specify a time zone, first make a choice using the Region or country selector to select a geographic region, then use the Time zone selector to select your required time zone. If you do not see the time zone you want, try selecting “Miscellaneous” in the Region or country list.

  5. Select Create Application VM.
