Microsoft.Compute.CredentialsCombo UI element

The CredentialsCombo element is a group of controls with built-in validation for Windows passwords, and Linux passwords or SSH public keys.

UI sample

For Windows, the password control is displayed.

For Linux with Password selected, the password control is displayed:

For Linux with SSH public key selected, the SSH key control is displayed:

The SSH public key source has three options:

  • Generate new key pair: Provide a name to create a new SSH key pair.
  • Use existing key stored in Azure: Select an existing SSH public key stored in Azure.
  • Use existing public key: Use an SSH public key that you already created. For example, an SSH public key that was created on a local computer.

For the Generate new key pair option, the keys are generated on the Review+Create tab after you select Create and Download private key and create resource.

Schema

For Windows, use the following schema:

{
  "name": "element1",
  "type": "Microsoft.Compute.CredentialsCombo",
  "label": {
    "password": "Password",
    "confirmPassword": "Confirm password"
  },
  "toolTip": {
    "password": ""
  },
  "constraints": {
    "required": true,
    "customPasswordRegex": "^(?=.*[A-Za-z])(?=.*\\d)[A-Za-z\\d]{12,}$",
    "customValidationMessage": "The password must be alphanumeric, contain at least 12 characters, and have at least 1 letter and 1 number."
  },
  "options": {
    "hideConfirmation": false
  },
  "osPlatform": "Windows",
  "visible": true
}

For Linux, use the following schema:

{
  "name": "element1",
  "type": "Microsoft.Compute.CredentialsCombo",
  "label": {
    "authenticationType": "Authentication type",
    "password": "Password",
    "confirmPassword": "Confirm password",
    "sshPublicKey": "SSH public key"
  },
  "toolTip": {
    "authenticationType": "",
    "password": "",
    "sshPublicKey": ""
  },
  "constraints": {
    "required": true,
    "customPasswordRegex": "^(?=.*[A-Za-z])(?=.*\\d)[A-Za-z\\d]{12,}$",
    "customValidationMessage": "The password must be alphanumeric, contain at least 12 characters, and have at least 1 letter and 1 number."
  },
  "options": {
    "hideConfirmation": false,
    "hidePassword": false
  },
  "osPlatform": "Linux",
  "visible": true
}

Sample output

If osPlatform is Windows, or osPlatform is Linux and the user provided a password instead of an SSH public key, the control returns the following output:

{
  "authenticationType": "password",
  "password": "p4ssw0rddem0",
}

If osPlatform is Linux and the user provided an SSH public key, the control returns the following output:

{
  "authenticationType": "sshPublicKey",
  "sshPublicKey": "AAAAB3NzaC1yc2EAAAABIwAAAIEA1on8gxCGJJWSRT4uOrR13mUaUk0hRf4RzxSZ1zRbYYFw8pfGesIFoEuVth4HKyF8k1y4mRUnYHP1XNMNMJl1JcEArC2asV8sHf6zSPVffozZ5TT4SfsUu/iKy9lUcCfXzwre4WWZSXXcPff+EHtWshahu3WzBdnGxm5Xoi89zcE=",
  "sshKeyName": "demo-public-key-name",
  "generateNewSshKey": false
}
  • When Generate new key pair is selected, the sshPublicKey property is empty. The reason is because on the Review+Create tab the keys are generated after you select Create and Download private key and create resource.
  • The sshKeyName property contains a name only when a new SSH key pair is generated in Azure or for a key already stored in Azure.
  • The generateNewSshKey is false when you use an existing key. When a new key pair is generated, the value is true.

Remarks

  • osPlatform must be specified, and can be either Windows or Linux.
  • If constraints.required is set to true, then the password or SSH public key text boxes must have values to validate successfully. The default value is true.
  • If options.hideConfirmation is set to true, then the second text box for confirming the user's password is hidden. The default value is false.
  • If options.hidePassword is set to true, then the option to use password authentication is hidden. It can be used only when osPlatform is Linux. The default value is false.
  • More constraints on the allowed passwords can be implemented by using the customPasswordRegex property. The string in customValidationMessage is displayed when a password fails custom validation. The default value for both properties is null. The schema shows an example of each property.
