Azure Marketplace Azure Application (formerly known as Solution Template) Helpers

The maven projects in this repository provide help for creating Azure Marketplace offers of type "Azure Application". For more details on Azure Applications (formerly known as Solution Templates) see Marketplace Solution Templates.

Usage

  1. Clone this repository locally

  2. Build and install the arm-assembly maven project locally.

    cd arm-assembly && mvn -DskipTests clean install
    
  3. Build and install the arm-parent maven project locally.

    cd arm-parent && mvn -DskipTests clean install
    
  4. Clone arm-ttk as a sibling of this directory. This is necessary because the test phase of the arm-parent maven project will run the tests in ${basedir}/../arm-ttk against your solution template. You must ensure the preconditions for running the tests are met, as described in the test documentation. Test documentation is found in arm-ttk README.

    If you want to put the tests in a different location, set the template.validation.tests.directory property.

  5. Create a maven project with the following layout

    ├── pom.xml
    └── src
        └── main
            ├── arm
            │   ├── createUiDefinition.json
            │   ├── mainTemplate.json
            └── scripts
                └── any scripts that are referenced in the mainTemplate.json
    

    In the pom.xml shown above, declare the parent like this:

    <parent>
        <groupId>com.microsoft.azure.iaas</groupId>
        <artifactId>azure-javaee-iaas-parent</artifactId>
        <version>whatever version you get from step 3</version>
        <relativePath></relativePath>
    </parent>
    
  6. Run the build

    # build for production
    mvn -Ptemplate-validation-tests clean install
    
    # build for development
    mvn -Ptemplate-validation-tests -Ddev clean install
    

    This will run the tests against your solution template. The output should look similar to the following.

    mvn -Ptemplate-validation-tests clean install

    ...   
    

    The zip file is what must be uploaded to the Azure marketplace as described in "Package file (.zip)"

Contents

arm-parent

This is intended to be the parent POM for a maven project that represents an Azure Application.

arm-assembly

The maven assembly that creates the Package file (.zip).

Tips for publishing Azure Applications to the Marketplace

These lessons are taken from the experience of publishing the Oracle WebLogic on Azure Application Offers to the marketplace, but apply to any Azure Application. See arm-oraclelinux-wls and its sibling projects for examples of how this parent pom is used.

Please also read the ARM Template Best Practices document.

General Lessons for all json files

  • Format all json files with SHIFT+ALT+F in VS Code.

General Lessons for mainTemplate.json

  • You must include tracking pid in resources, pid is defined in property file whose uri is specified with properties template.pid.properties.url for production and template.microsoft.pid.properties.url for development in pom.xml. Like:

    {
     	"apiVersion": "2019-10-01",
     	"name": "${cluster.start}",
     	"type": "Microsoft.Resources/deployments",
     	"properties": {
     		"mode": "Incremental",
     		"template": {
     			"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
     			"contentVersion": "1.0.0.0",
     			"resources": [
     			]
     		}
     	}
     },
    ...
    {
     	"apiVersion": "2019-10-01",
     	"name": "${cluster.end}",
     	"type": "Microsoft.Resources/deployments",
     	"dependsOn": [
     		"[resourceId('Microsoft.Resources/deployments', 'clusterLinkedTemplate')]",
     		"[resourceId('Microsoft.Resources/deployments', 'keyVaultLinkedAppGatewayTemplate')]"
     	],
     	"properties": {
     		"mode": "Incremental",
     		"template": {
     			"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
     			"contentVersion": "1.0.0.0",
     			"resources": [
     			]
     		}
     	}
     }
    
    

    If you don't, you'll get this when you try to deploy:

    Error Message Azure usage tracking resource missing in one or more ARM
    templates. To resolve, add a tracking GUID to the ARM template in
    mainTemplate.json packages for the following plan:
    20190829-arm-oraclelinux-wls-cluster. For more details, see
    https://aka.ms/aboutinfluencedrevenuetracking.
    

    In the above snippet the value ${tracking.pid} is templated by maven because we are using maven to create the zip bundle.

  • _artifactsLocationSasToken is required in parameters. Like so:

    "_artifactsLocationSasToken": {
        "type": "securestring",
        "metadata": {
            "description": "The sasToken required to access _artifactsLocation.  When the template is deployed using the accompanying scripts, a sasToken will be automatically generated. Use the defaultValue if the staging location is not secured."
        },
        "defaultValue": ""
    },
    
    
  • Do not include any scripts that download resources from user specific sites. For example:

    curl -s https://raw.githubusercontent.com/typekpb/oradown/master/oradown.sh  | bash -s -- --cookie=accept-weblogicserver-server --username="${otnusername}" --password="${otnpassword}" https://download.oracle.com/otn/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz
    

    Is not allowed. To get the same effect, include the script in the scripts directory of the zip and reference it like so:

    export SCRIPT_PWD=`pwd`
    chmod ugo+x ${SCRIPT_PWD}/oradown.sh 
    
    ${SCRIPT_PWD}/oradown.sh --cookie=accept-weblogicserver-server --username="${otnusername}" --password="${otnpassword}" https://download.oracle.com/otn/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz
    
  • Use the latest versions for all the things.

    For example:

    az provider show --namespace Microsoft.Storage --query "resourceTypes[*].resourceType" --out table
    

    From the output, pick storageAccounts.

    az provider show --namespace Microsoft.Storage --query "resourceTypes[?resourceType=='storageAccounts'].apiVersions | [0]" --out table
    

    Scan your mainTemplate.json for date strings:

    grep "[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]" mainTemplate.json
    
  • In parameters, _artifactsLocation, defaultValue must be [deployment().properties.templateLink.uri]. This will cause any scripts bundled in the zip to be referencable like so:

    "settings": {
        "fileUris": [
            "[uri(parameters('_artifactsLocation'), concat('scripts/', variables('ScriptFileName'), parameters('_artifactsLocationSasToken')))]",
            "[uri(parameters('_artifactsLocation'), concat('scripts/', variables('oradownScript'), parameters('_artifactsLocationSasToken')))]"
        ],
    
  • When referencing scripts to be run as "type": "Microsoft.Compute/virtualMachines/extensions", include them in the zip bundle, put them in the scripts sub-directory of the top level of the zip bundle, and reference them like so:

    "settings": {
      "fileUris": [
         "[uri(parameters('_artifactsLocation'), concat('scripts/', variables('ScriptFileName'), parameters('_artifactsLocationSasToken')))]"
      ],
      "commandToExecute": "[concat('sh',' ',variables('ScriptFileName'),' ',parameters('acceptOTNLicenseAgreement'),' ',parameters('otnAccountUsername'),' ',parameters('otnAccountPassword'))]"
    }
    
  • For any scripts referenced in mainTemplate.json, put the script name in the variables section, like so:

    "oradownScript": "oradown.sh",
    
  • Define one or more parameters with guid() for when you need uniqueness. This must be done in parameters with a defaultValue. Like so:

    "guidValue": {
          "type": "string",
          "defaultValue": "[newGuid()]"
    },
    
    ...
    
    "variables": {
       "storageAccountName": "[concat(take(replace(parameters('guidValue'),'-',''),6),'olvm')]",
    
  • When referring to a storageAccountName, it must be unique, like so:

     "variables": {
       "storageAccountName": "[concat(take(replace(guid(toLower(resourceGroup().name)),'-',''),6),'olvm')]",
    

General Lessons for createUiDefinition.json

  • Be as specific as possible in tooltips. For example:

    {
      "name": "adminUsername",
      "type": "Microsoft.Common.TextBox",
      "label": "Username for admin account of VMs",
      "defaultValue": "weblogic",
      "toolTip": "Use only letters and numbers",
      "constraints": {
          "required": true,
          "regex": "^[a-z0-9A-Z]{1,30}$",
          "validationMessage": "The value must be 1-30 characters long and must only contain letters and numbers."
      },
      "visible": true
    },   
    

    Instead of

    "toolTip": "Use only allowed characters",
    

    Another example:

    {
        "name": "managedServerPrefix",
        "type": "Microsoft.Common.TextBox",
        "label": "Managed Server Prefix",
        "toolTip": "The string to prepend to the name of the managed server.  Must start with letters and not have a run of more than eight digits.",
        "defaultValue": "msp",
        "constraints": {
            "required": true,
            "regex": "^[a-z0-9A-Z]{3,79}$",
            "validationMessage": "The prefix must be between 3 and 79 characters long and contain letters, numbers only."
        }
    },   
    
  • Try to sort things alphabetically.

  • For elements of "type": "Microsoft.Common.PasswordBox", use the most restrictive RegEx you possible. Such as:

    {
        "name": "adminPasswordOrKey",
        "type": "Microsoft.Common.PasswordBox",
        "label": {
            "password": "Password for admin account of VMs",
            "confirmPassword": "Confirm password"
        },
        "toolTip": "Password for admin account of VMs",
        "constraints": {
            "required": true,
            "regex": "^((?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])|(?=.*[0-9])(?=.*[a-z])(?=.*[!@#$%^&*])|(?=.*[0-9])(?=.*[A-Z])(?=.*[!@#$%^&*])|(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*])).{12,72}$",
            "validationMessage": "Password must be at least 12 characters long and have 3 out of the following: one number, one lower case, one upper case, or one special character"
        },
        "options": {
            "hideConfirmation": false
        },
        "visible": true
    },
    

    Ensure the validationMessage expresses exactly what the RegEx requires.

    Ensure the minimum length of the password is at least 12 characters.

    Ensure "hideConfirmation" is false, like so.

    "options": {
      "hideConfirmation": false
    },
    
    
  • If the element of type "type": "Microsoft.Common.PasswordBox" is actually a value from another site, such as the password for an user id that is an Oracle account or IBM account, use no RegEx and call it out specifically in the validationMessage, like so:

    {
        "name": "otnAccountPassword",
        "type": "Microsoft.Common.PasswordBox",
        "label": {
            "password": "Password for OTN Account",
            "confirmPassword": "Confirm password"
        },
        "toolTip": "Password for OTN Account",
        "constraints": {
            "required": true,
            "validationMessage": "Validation constraints for OTN accounts apply here."
        },
        "options": {
            "hideConfirmation": false
        },
        "visible": true
    }
    
    
  • Ensure the type of each output is correct with respect to what the mainTemplate.json expects. For example, if something is an int but it is entered by the user as a string, it must be converted with the int() function, like so:

    "outputs": {
    ...
        "numberOfInstances": "[int(basics('numberOfInstances'))]",
    ...
    }   
    
  • Be mindful of the total length of strings. For example, we had dnsLabelPrefix with a max length of 79. We were told to shorten it a lot. I chose 10, like so:

    {
        "name": "dnsLabelPrefix",
        "type": "Microsoft.Common.TextBox",
        "label": "DNS Label Prefix",
        "toolTip": "The string to prepend to the DNS label.",
        "defaultValue": "wls",
        "constraints": {
            "required": true,
            "regex": "^[a-z0-9A-Z]{3,10}$",
            "validationMessage": "The prefix must be between 3 and 10 characters long and contain letters, numbers only."
        }
    }
    
  • If there are any legal things that require acceptance of TOS, prevent the deployment from proceeding unless they accept the TOS, like so:

    {
        "name": "acceptOTNLicenseAgreement",
        "label": "Accept OTN License Agreement",
        "type": "Microsoft.Common.TextBox",
        "tooltip": "A value of N indicates you do not accept the OTN License Agreement.  In that case the deployment will fail.",
        "visible": true,
        "defaultValue": "Y",
        "constraints": {
            "required": true,
            "regex": "^[Yy]$",
            "validationMessage": "The value must be Y/y to proceed with deployment."
        }
    },
    
    

arm-oraclelinux-wls

mainTemplate.json

  • in the dictionary with "type": "Microsoft.Compute/virtualMachines", there is a dictionary like this:

    "diagnosticsProfile": {
      "bootDiagnostics": {
         "enabled": true,
         "storageUri": ""
      }
    }
    

    The value for storageUri:

    • must not use concat.

    • must use resoucreId()

    Like so:

    "diagnosticsProfile": {
    "bootDiagnostics": {
       "enabled": true,
       "storageUri": "[reference(resourceId('Microsoft.Storage/storageAccounts/', variables('storageAccountName')), '2019-06-01').primaryEndpoints.blob]"
    }
    }
    

arm-oraclelinux-wls-admin

mainTemplate.json

  • Elements of type "type": "Microsoft.Storage/storageAccounts" must have an empty properties, like so:

    {
       "type": "Microsoft.Storage/storageAccounts",
       "apiVersion": "2019-06-01",
       "name": "[variables('storageAccountName')]",
       "location": "[parameters('location')]",
       "sku": {
          "name": "[variables('storageAccountType')]"
       },
       "kind":"Storage",
       "properties": {
    
       }
    },
    
    
  • Things that show up in domain names must be both shortish and unique. Like so:

    {
       "type": "Microsoft.Network/publicIPAddresses",
       "apiVersion": "2018-11-01",
       "name": "[variables('publicIPAddressName')]",
       "location": "[parameters('location')]",
       "properties": {
          "publicIPAllocationMethod": "[variables('publicIPAddressType')]",
          "dnsSettings": {
             "domainNameLabel": "[concat(toLower(parameters('dnsLabelPrefix')),'-',take(replace(parameters('guidValue'), '-', ''), 10),'-',toLower(parameters('wlsDomainName')))]"
          }
       }
    }
