Provision Config Server

Azure portal

The following steps show you how to provision a Config Server for Spring in your Azure Container Apps:

  1. Navigate to your Azure Container Apps environment in the Azure portal.

  2. In the menu, select Services > Services.

  3. Open the Configure drop-down list, and then select Java component.

  4. In the Configure Java component panel, enter the following values:

    Property Value
    Java component type Select Config Server for Spring.
    Java component name Enter configserver.

  5. In the Git repositories section, select Add, and then migrate the values from Application Configuration Service to here, as shown in the following table. Choose one repository as the default repository of Config Server for Spring.

    Property Value
    Type Select DEFAULT.
    URI Enter the value of URI of the repository.
    Branch name Enter the value of label of the repository.
    Search paths Enter the value of search path of the repository.
    Authentication Select the authentication type of the repository and enter the corresponding information.

    Leave the rest of the fields with the default values and then select Add.

  6. If you have multiple repositories, select Add to migrate other repositories. For Type, select Other, and then migrate other properties as shown in the previous step and the following table:

    Property Value
    Type Select DEFAULT.
    Pattern Enter the Patterns value for the repository in the {application} or {application}/{profile} format.

  7. In the Binding section, open the dropdown to select the apps to bind to the Config Server for Spring.

  8. Select Next.

  9. To set up Config Server, on the Review tab, select Configure, and then follow the instructions in the configuration section.

After successful creation, you can see that the Provisioning State of Config Server for Spring is Succeeded.

Azure CLI

Use the following command to create and configure the Config Server for Spring Java component:

az containerapp env java-component config-server-for-spring create \
    --resource-group <resource-group-name> \
    --name <config-server-name> \
    --environment <azure-container-app-environment-name> \
    --min-replicas 1 \
    --max-replicas 1 \
    --configuration spring.cloud.config.server.git.uri=<URI> spring.cloud.config.server.git.default-label=<label>

All properties are set using the format --configuration <CONFIGURATION_KEY>=<CONFIGURATION_VALUE>. To map existing configurations to the key-value pairs of the Config Server, see the configuration section.

Resource allocation

The container resource allocation for the managed Config Server in Azure Container Apps is fixed to the following values:

  • CPU: 0.5 vCPU
  • Memory: 1 Gi

To configure the instance count of Config Server for Spring, you need to update the parameters --min-replicas and --max-replicas with the same value. This configuration ensures that the instance count remains fixed. Currently, the system doesn't support autoscaling configurations for dynamic scaling.
