SDK do Azure App Configuration para Python

Gerenciamento centralizado de configurações com sinalizadores de recursos e configurações dinâmicas.

Instalação

pip install azure-appconfiguration

Variáveis de Ambiente

AZURE_APPCONFIGURATION_CONNECTION_STRING=Endpoint=https://<name>.azconfig.io;Id=...;Secret=...
# Or for Entra ID:
AZURE_APPCONFIGURATION_ENDPOINT=https://<name>.azconfig.io

Autenticação

String de Conexão

from azure.appconfiguration import AzureAppConfigurationClient

client = AzureAppConfigurationClient.from_connection_string(
    os.environ["AZURE_APPCONFIGURATION_CONNECTION_STRING"]
)

Entra ID

from azure.appconfiguration import AzureAppConfigurationClient
from azure.identity import DefaultAzureCredential

client = AzureAppConfigurationClient(
    base_url=os.environ["AZURE_APPCONFIGURATION_ENDPOINT"],
    credential=DefaultAzureCredential()
)

Configurações de Configuração

Obter Configuração

setting = client.get_configuration_setting(key="app:settings:message")
print(f"{setting.key} = {setting.value}")

Obter com Rótulo

# Labels allow environment-specific values
setting = client.get_configuration_setting(
    key="app:settings:message",
    label="production"
)

Definir Configuração

from azure.appconfiguration import ConfigurationSetting

setting = ConfigurationSetting(
    key="app:settings:message",
    value="Hello, World!",
    label="development",
    content_type="text/plain",
    tags={"environment": "dev"}
)

client.set_configuration_setting(setting)

Excluir Configuração

client.delete_configuration_setting(
    key="app:settings:message",
    label="development"
)

Listar Configurações

Todas as Configurações

settings = client.list_configuration_settings()
for setting in settings:
    print(f"{setting.key} [{setting.label}] = {setting.value}")

Filtrar por Prefixo de Chave

settings = client.list_configuration_settings(
    key_filter="app:settings:*"
)

Filtrar por Rótulo

settings = client.list_configuration_settings(
    label_filter="production"
)

Sinalizadores de Recursos

Definir Sinalizador de Recurso

from azure.appconfiguration import ConfigurationSetting
import json

feature_flag = ConfigurationSetting(
    key=".appconfig.featureflag/beta-feature",
    value=json.dumps({
        "id": "beta-feature",
        "enabled": True,
        "conditions": {
            "client_filters": []
        }
    }),
    content_type="application/vnd.microsoft.appconfig.ff+json;charset=utf-8"
)

client.set_configuration_setting(feature_flag)

Obter Sinalizador de Recurso

setting = client.get_configuration_setting(
    key=".appconfig.featureflag/beta-feature"
)
flag_data = json.loads(setting.value)
print(f"Feature enabled: {flag_data['enabled']}")

Listar Sinalizadores de Recursos

flags = client.list_configuration_settings(
    key_filter=".appconfig.featureflag/*"
)
for flag in flags:
    data = json.loads(flag.value)
    print(f"{data['id']}: {'enabled' if data['enabled'] else 'disabled'}")

Configurações Somente Leitura

# Make setting read-only
client.set_read_only(
    configuration_setting=setting,
    read_only=True
)

# Remove read-only
client.set_read_only(
    configuration_setting=setting,
    read_only=False
)

Snapshots

Criar Snapshot

from azure.appconfiguration import ConfigurationSnapshot, ConfigurationSettingFilter

snapshot = ConfigurationSnapshot(
    name="v1-snapshot",
    filters=[
        ConfigurationSettingFilter(key="app:*", label="production")
    ]
)

created = client.begin_create_snapshot(
    name="v1-snapshot",
    snapshot=snapshot
).result()

Listar Configurações de Snapshot

settings = client.list_configuration_settings(
    snapshot_name="v1-snapshot"
)

Cliente Assíncrono

from azure.appconfiguration.aio import AzureAppConfigurationClient
from azure.identity.aio import DefaultAzureCredential

async def main():
    credential = DefaultAzureCredential()
    client = AzureAppConfigurationClient(
        base_url=endpoint,
        credential=credential
    )
    
    setting = await client.get_configuration_setting(key="app:message")
    print(setting.value)
    
    await client.close()
    await credential.close()
