Use valid server names

Operational Excellence · Azure Database for MariaDB · Rule · 2022_12

Azure Database for MariaDB servers should meet naming requirements.

Description

When naming Azure resources, resource names must meet service requirements. The requirements for Azure Database for MariaDB server names are:

• Between 3 and 63 characters long.
• Lowercase letters, numbers, and hyphens.
• Can't start or end with a hyphen.
• MariaDB server names must be globally unique.

Recommendation

Consider using names that meet Azure Database for MariaDB server naming requirements. Additionally consider naming resources with a standard naming convention.

Examples

Configure with Azure template

To deploy servers that pass this rule:

• Set the name property to align to resource naming requirements.

For example:

Azure Template snippet

{
  "type": "Microsoft.DBforMariaDB/servers",
  "apiVersion": "2018-06-01",
  "name": "[parameters('name')]",
  "location": "[parameters('location')]",
  "sku": {
    "name": "[parameters('sku')]",
    "tier": "GeneralPurpose",
    "capacity": "[parameters('skuCapacity')]",
    "size": "[format('{0}', parameters('skuSizeMB'))]",
    "family": "Gen5"
  },
  "properties": {
    "sslEnforcement": "Enabled",
    "minimalTlsVersion": "TLS1_2",
    "createMode": "Default",
    "version": "10.3",
    "administratorLogin": "[parameters('administratorLogin')]",
    "administratorLoginPassword": "[parameters('administratorLoginPassword')]",
    "publicNetworkAccess": "Disabled",
    "storageProfile": {
      "storageMB": "[parameters('skuSizeMB')]",
      "backupRetentionDays": 7,
      "geoRedundantBackup": "Enabled"
    }
  }
}

Configure with Bicep

To deploy servers that pass this rule:

• Set the name property to align to resource naming requirements.

For example:

Azure Bicep snippet

resource server 'Microsoft.DBforMariaDB/servers@2018-06-01' = {
  name: name
  location: location
  sku: {
    name: sku
    tier: 'GeneralPurpose'
    capacity: skuCapacity
    size: '${skuSizeMB}'
    family: 'Gen5'
  }
  properties: {
    sslEnforcement: 'Enabled'
    minimalTlsVersion: 'TLS1_2'
    createMode: 'Default'
    version: '10.3'
    administratorLogin: administratorLogin
    administratorLoginPassword: administratorLoginPassword
    publicNetworkAccess: 'Disabled'
    storageProfile: {
      storageMB: skuSizeMB
      backupRetentionDays: 7
      geoRedundantBackup: 'Enabled'
    }
  }
}
