Creating and Launching Instances

Describes how to create and launch compute instances on your Roving Edge Infrastructure devices.

Having completed administrating your Roving Edge Infrastructure devices, you can now start running tasks using the on-device services and the data provisioned to your devices. Start by creating and launching a compute instance.

  1. Open the navigation menu and select Compute > Instances. The Instances page appears. All instances are listed in tabular form.

  2. Click Create Instance. The Create Compute Instance dialog box appears.

  3. Complete the following:

    • Name: Enter a name for the instance.

    • Image or operating system: Click Change Image. The Browse All Images dialog box appears. Select one of the following image options:

      • Platform Images tab: Check the pre-built image you want for the instance from the list and click Select Image.
      • Custom Images tab: Click Select Image. The image you selected is displayed in the Image or operating system box.

    • Shape: Click Change Shape. The Browse All Shapes dialog box appears. Select a Standard or Specialty shape type, then select one of the corresponding shapes that appear. Click Select Shape. The shape you selected is displayed in the Shape box.

    • Select a virtual cloud network: Select a virtual cloud network from the list.
    • Select a subnet: Select a subnet associated with the virtual cloud network from the list.

    • IP address: Select an IP address option:

      • Assign a public IP address (if selected, an IP address from the external CIDR is used)
      • Do not assign a public IP address

    • Specify a custom boot volume size: Check if you do not want to use the default boot volume size. Enter the size in the Boot volume size box.

    • SSH key: Select an SSH key option:

      • Choose SSH key file: Click browse to a location and navigate to your SSH key file where you can select it for upload. You can also drag the file into the SSH keys box.
      • Paste SSH keys: Copy and paste the SSH key directly into the SSH keys box.
      Note

      If the original image had the user keys on it, the new keys might not be added to the resulting instance, depending on the image specifics.

  4. Click Create. Upon creation of the instance, the new instance's Details page opens automatically.

  5. Review the contents of the instance's Details page. It contains information such as its current state (indicated by the image in the upper left corner), IP addresses used, the image used, shape settings. You can view the boot volume, and attached VNICs by clicking their respective links in the lower left corner. Creation of the instance can take several minutes. During this time, the state is Provisioning. When the creation is complete, the state changes to Running. This state indicates that the instance is now launched.

See Instances for Roving Edge Infrastructure Devices for more information.

Creating a Block Volume

After you have created and launched your initial instance, create a block volume that you can attach to the instance.

  1. Open the navigation menu and select Block Storage > Block Volumes. The Block Volumes page appears. All block volumes are listed in tabular form.

  2. Select a State from the list to limit the block volumes displayed to that state.

  3. Click Create Block Volume. The Create Block Volume dialog box appears.

  4. Complete the following:

    • Name: A user-friendly name or description.

    • Size: Must be between 50 GB and 6 TB. You can choose in 1 GB increments within this range. The default is 300 GB. If you choose a size outside of your service limit, you might be prompted to request an increase.

  5. Check View detail page after this block volume is created to display the block volume's Details page after you create it.

  6. Click Create Block Volume. The volume is ready to attach after its icon no longer lists it as Provisioning in the Volume list.

Attaching the Block Volume

After you have created your block volume, attach it to the instance you previously created and launched.

  1. Open the navigation menu and select Compute > Instances. The Instances page appears. All instances are listed in tabular form.

  2. Select a State from the list to limit the instances displayed to that state.

  3. Click the instance to which you want to attach a block volume under Instances.

  4. Click Attached Block Volumes in the lower left corner. The Attached Block Volumes page appears. All attached block volumes are listed in tabular form.

  6. Choose the volume selection option:

    • Select Volume: Select the volume from the Block Volume list.

    • Enter Volume OCID: Enter the OCID into the Block Volume OCID box.

  7. Select a Device Path: Choose one from the list of device paths. For example:

    /dev/oracleoci/oraclevdb

  8. Select the access type:

    • Read/Write

    • Read/Write - Shareable

    • Read-only

  9. Click Attach.

    The block volume appears in the Attached Block Volume page.
