Lets review a simple example. In this case, we only have one secret: a database connection string. Of course, if the procedure does not yet exist, an ALTER command will produce an error, but we can avoid that by starting the script with a stub creation routine that executes only if the procedure does not yet exist, and creates the object stub. If the file already exists, the site information in it will be overwritten. See Use an existing storage account. In the change log, we must include the step to create reference both the SQL script to create the table, and the special cmd step type for the data load. Well then consider how to define script and configuration files to: When scripting the creation of, and changes to, stored procedures, we should consider the following issues: The most common approach to the stored procedure (and UDF) scripting is drop-if-exists-the-create-new. In such cases, we need to deploy the same database project under different the target database name. OnExpiration: Delete the two supporting resources only when the retentionInterval setting is expired. 1. These scripts must run in this order: The configure-vm.sh script should look familiar, since its a collection of the steps we have used multiple times throughout this class. Well create a new Countries table, and then load it with data from a text file. To learn more, see Deployment script. There are various ways to mitigate and work around, such as using regular expressions to validate parameter input or using predefined parameters. If the database is in use while were applying the update, there will always be a period where the object is unavailable. In order to ensure this mapping works, T-SQL scripts should not explicitly switch to any particular user database (system ones like master or tempdb are OK). Another way to identify these resources is through their suffixes, which contain "azscripts". The deliver-deploy.sh script has a couple of variables that need to be set by the user. In the Script Status list, you view the results for each script you ran on client devices. Specify a new user every time, or you may end up resetting a user's login password and invalidating the user's previous connection credentials. We define in the replication project the new article/subscription definition, and so on, for the new table. To specify an existing storage account, add the following JSON to the property element of Microsoft.Resources/deploymentScripts: storageAccountName: specify the name of the storage account. The retention interval is between 1 and 26 hours (PT26H). Having the author and approver roles separated allows an important process check for the powerful tool that Run Scripts is. We can confirm this by checking the Extended Properties value in SSMS, as shown in Figure 3. A storage account and a container instance are needed for script execution and troubleshooting. Therefore, while we can perform such changes through the framework it is not a recommended way of using it. To select a collection of targets for your script: If a script does not run, for example because a target device is turned off during the one hour time period, you must run it again. Deployment script requires a new Azure Container Instance. The supporting files are copied to azscripts/azscriptinput at the runtime. Listing 7: Database name mapping in DatabaseNameMapping.config. See. This can be worked around by editing the script to have the correct defaults. Creates only a local Windows user and will not work if shared configuration is enabled. Storage account firewall rules aren't supported yet. Create a database with user using the defaults (local SQLExpress database): Create a new database and add the connection string information to existing publish settings file c:\profiles\UserA.PublishSettings: Description: Creates a database, a database user with all privileges on the database (at localhost), and saves the connection string information in a settings file. With this integration in Configuration Manager, you can use the Run Scripts functionality to do the following things: For more information about Configuration Manager security roles: deployment powershell azure directory active-directory hyper . You can replace the user deployment script file with a revised one, and rerun the deployment script from the Azure container instance. After adding validation, you should get errors if you're entering a value for a parameter that doesn't meet its validation. This is a rather involved script that dictates our deployment. supportingScriptUris: Specify an array of publicly accessible URLs to supporting files that are called in either scriptContent or primaryScriptUri. We use the installed dbForge DevOps Automation for SQL Server plugin. Occasionally, despite our careful testing, a deployment may cause unforeseen problems that man we need to roll it back. You can use the listKeys() function to retrieve the key. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. If the directory specified does not exist, an error will result. In a nutshell, it downloads and configures the NGINX web server our application uses to enable TLS and HTTPS so that our app can be used with AADB2C. Automate your deployment pipeline by using APIs and Azure DevOps After we look at the script as a whole, we will break down its individual sections. Instead of making long T-SQL scripts inserting the initial (static) data into the system I created a simple package that loaded that data from an Excel file. To demonstrate how this works, well return to the ExampleDB database project from the previous article, Automating SQL Server Database Deployments: A Worked Example. When you edit or copy a script, Configuration Manager doesn't persist the approval state. With such an approach, there is always a short period between dropping and recreating the procedure. Because scripts are powerful, versatile, and potentially deployed to many devices, you can separate the roles between the person that authors the script and the person that approves the script. To avoid such interruption, we can update the procedure using the ALTER command, so that the user permissions remain unchanged. DeploymentScriptOutputs is used for storing outputs. Create an object in Azure Active Directory (Azure AD). Use relative path to reference the supporting files from inline scripts and primary script files. However, we can access RunCommand from the Azure CLI which allows us to run any additional scripts on the VM that are needed. Create an Ansible Vault file to secure the user and password information. cleanupPreference. When the deployment utility, DBCreator.vbe,creates the database, it will substitute it with the target database name. For example, use utcNow as the value. How do we make it simple for a non-DBA to deploy such a multi-database project? Use infrastructure automation tools - Azure Virtual Machines See Clean up deployment script resources for how the script service cleans up the file share. application developer or tester) only has to know how to: Sometimes the database build/update process requires usage of external tools. If the application pool does not exist, it will be created. You can separate complicated logics into one or more supporting script files. It comes with the container images. The scriptContent shows a script with multiple lines. retentionInterval: Specify the time interval that a deploymentScript resource will be retained and after which will be expired and deleted. If a user happens to make a call during the update, SQL Server will simply delay the call until the procedure compiles, so it wont result in a failure and error message. We now understand what the Bash scripts are doing. In the folder, there are two more folders for the input and the output files: azscriptinput and azscriptoutput. The scripts simplify building custom tools to administer software and let you accomplish mundane tasks quickly, allowing you to get large jobs done more easily and more consistently. Listing 6: The batch file for exporting data. The middle section does some VM operations work, namely creating directories, granting privileges to those directories, and creating a Systemd unit file that will be used to deploy the application. All the configuration files in the framework, including the change log, specify the database name as an XML attribute, as shown in Figure 1. stored procedure) permissions in the same file as the object. Clients still running the current application version can use the original procedure, and updated clients can use the new one. Deployment principal must have permissions to manage the storage account, which includes read, create, delete file shares. The utcNow function can only be used in the default value for a parameter. Configuration Manager has an integrated ability to run PowerShell scripts. For deployment script API version 2020-10-01 or later, there are two principals involved in deployment script execution: Deployment principal (the principal used to deploy the template): this principal is used to create underlying resources required for the deployment script resource to execute a storage account and an Azure container instance. Run the SetupSiteForPublish.ps1 script with no arguments: The script creates a user and site for non-admin publishing and saves the publish profile information in a file on the desktop. At this stage, you build the database package and deploy it from the Script Folder on the server. A huge benefit of using the Azure CLI from a shell terminal is that we can bundle many commands together in a script. 9 Deployment Automation Platforms for Modern Applications In the PowerShell chapter you will be writing your own automated deployment script. Listing 1: A template for creating or altering a stored procedure. Multi-environment Deployment. The deployment tool should, when run against such a database, fail to identify the correct database build number and exit with an error. Table of Contents. In this way, we can use any tool that we can call from the command line as part of the upgrade. The example above illustrates suggested usage of that functionality. DeploymentScriptContainerGroupNameInvalid, The Azure container instance name (ACI) specified doesn't meet the ACI requirements. Both actions use the same wizard experience as when you create a new script. In the simplest possible case, we drop and then recreate all the database permissions and roles. The SQL Server security model, described simply, consists of two levels: Therefore, it is a best practice for configuration files to reflect that separation with our security configuration consisting of two parts: As discussed previously, the information in server-level login/user configuration file is environment-specific, meaning that each particular target environment (identified by the server\instance name), may use a different login or a Windows group for the same set of database roles. For this section we will focus primarily on the Deploy stage, but it should be noted . The requirements for using an existing storage account: These combinations support file shares. Description: For a specified site and user account, enables the specified user to publish to the specified site. A deployment script can use Microsoft Graph to create and work with objects in Azure AD. This pipeline will demonstrate how to automate database changed in an automation fashion by maintaining a list of SQL servers in your environment. Instead, we have two options, in response to a failed deployment: We perform unit testing of database code and objects, and then perform system unit testing. Configuration Manager won't overwrite the default value since it will never modify the script directly. In this section, we delve deeper into the details of scripting the database projects covering how to upgrade stored procedures without service interruption, security scripting, and how to write configuration-driven scripts. Changing the resource name creates a new deploymentScripts resource. Figure 1: The DBName attribute, in the Change Log. This is an unwise decision that eventually runs into serious problems. You must be an administrator on the machine. It also provides centralized automation execution, job scheduling, and a visual dashboard with audit trails to measure performance. To disable Copilot for your environment, follow these steps. All of the name variables use the underlying student_name variable to create a consistent naming pattern. You can also consider using string substitution as it is shown in the previous JSON sample. How is that configuration data used? For more information, see Develop deployment scripts. These scripts can be used for performing custom steps such as: The deployment script resource is only available in the regions where Azure Container Instance is available. To log in with a different identity, you can call Connect-AzAccount in the script. When you use Azure CLI deployment scripts, you can use commands within the az ad command group to work with applications, service principals, groups, and users. Currently, only user-assigned managed identity is supported. Use deployment scripts in templates - Azure Resource Manager Eventually, in the project lifetime, some of the databases will require a change that we must deploy immediately, before changes to the others are complete. Proactively mitigate potential risks with instant problem diagnosis and customizable alerting wherever your databases are hosted. If a direct database modification is unavoidable, for some reason, then we must propagate the change back into the database project. Default setting is Always, which means deleting the supporting resources despite the terminal state (Succeeded, Failed, Canceled). You're able to turn off secondary approval, for ease of testing. Paste your original escaped string into the tool, and then select Escape. With the deploymentScripts resource, users can execute scripts in Bicep deployments and review execution results. PowerShell2 must be installed (this is built into Windows Server 2008 R2; for Windows Server 2008, you can get PowerShell2 as an update from here: The Web Server (IIS) role must be enabled in Server Manager. Extract data from VM output into useable variables: Create a new secret in the Key Vault with a description, name, and value, Attach a new access policy to the Key Vault granting the VM access, Send three separate Bash scripts to the VM using, Print out the public IP address of the VM, The virtual machine system-managed identity, Manual deployment with a GUI: Azure Portal, Manual deployment with a CLI tool: Azure CLI, Automated deployment via shell scripts like.
