Azure KMS Scripts

Scripts in this directory can be used to run driver CSFLE tests on a remote Azure Virtual Machine.

Background

Use create-and-setup-vm.sh to create the remote Azure Virtual Machine. Use delete-vm.sh to delete the remote Azure Virtual Machine. The distro used must have the Azure Command-Line Interface (az) version 2.25.0 or higher installed. At time of writing, distros with az installed include:

  • debian10
  • debian11
  • ubuntu1804
  • ubuntu2004
  • ubuntu2204 If another distro is required, consider filing a BUILD ticket similar to BUILD-16836.

The image of the remote Virtual Machine defaults to the URN Debian:debian-11:11:0.20221020.1174. It may be overridden with the environment variable AZUREKMS_IMAGE set to the value of --image in az vm create. See Azure documentation for valid values.

The list of images may be determined with az vm image --list. The following script can get the latest version of the debian-11 image:

LATEST_DEBIAN_URN=$(az vm image list -p Debian -s 11 --all --query "[?offer=='debian-11'].urn" -o tsv | sort -u | tail -n 1)
echo "LATEST_DEBIAN_URN=$LATEST_DEBIAN_URN"

The URN may be passed as AZUREKMS_IMAGE.

Usage with AWS Vault

See Secrets Handling for details on how to access the secrets from the drivers/azurekms vault.

Your Evergreen config should look something like:

- name: testazurekms_task_group
  setup_group_can_fail_task: true
  setup_group_timeout_secs: 1800
  teardown_group_can_fail_task: true
  teardown_group_timeout_secs: 1800
  setup_group:
    - func: fetch source
    - func: prepare resources
    - command: subprocess.exec
      params:
        binary: bash
        args:
          - ${DRIVERS_TOOLS}/.evergreen/csfle/azurekms/setup.sh
  teardown_group:
    - command: subprocess.exec
      params:
        binary: bash
        args:
          - ${DRIVERS_TOOLS}/.evergreen/csfle/azurekms/teardown.sh
    - func: "upload test results"
  tasks:
  - testazurekms-task

And your task should include a script that does something like:

source $DRIVERS_TOOLS/.evergreen/csfle/azurekms/secrets-export.sh
export AZUREKMS_PRIVATEKEYPATH=/tmp/testazurekms_privatekey
echo "Copying files ... begin"
tar czf /tmp/mongo-python-driver.tgz .
AZUREKMS_SRC="/tmp/mongo-python-driver.tgz" \
AZUREKMS_DST="~/" \
    $DRIVERS_TOOLS/.evergreen/csfle/azurekms/copy-file.sh
echo "Copying files ... end"
echo "Untarring file ... begin"
AZUREKMS_CMD="tar xf mongo-python-driver.tgz" \
    $DRIVERS_TOOLS/.evergreen/csfle/azurekms/run-command.sh
echo "Untarring file ... end"
AZUREKMS_CMD="KEY_NAME=\"$AZUREKMS_KEYNAME\" KEY_VAULT_ENDPOINT=\"$AZUREKMS_KEYVAULTENDPOINT\" SUCCESS=true TEST_FLE_AZURE_AUTO=1 ./.evergreen/tox.sh -m test-eg" $DRIVERS_TOOLS/.evergreen/csfle/azurekms/run-command.sh
