Config Consul

A Consul configuration center driver for Hyperf.

Installation

composer require friendsofhyperf/config-consul

The package installs its Hyperf Config Center, Consul, codec, and stringable dependencies automatically.

Configuration

// config/autoload/config_center.php

return [
    'enable' => true,
    'driver' => 'consul',
    'drivers' => [
        'consul' => [
            'driver' => FriendsOfHyperf\ConfigConsul\ConsulDriver::class,
            'packer' => Hyperf\Codec\Packer\JsonPacker::class,
            'client' => [
                'uri' => env('CONSUL_URI'),
                'token' => env('CONSUL_TOKEN'),
            ],
            'namespaces' => [
                '/application',
            ],
            'mapping' => [
                // consul key => config key
                '/application/test' => 'test',
            ],
            'interval' => 5,
        ],
    ],
];

Option	Description
enable	Enables Hyperf Config Center.
driver	Selects the consul driver configuration.
drivers.consul.driver	The driver class. Use ConsulDriver::class.
drivers.consul.packer	Unpacks each mapped value. Defaults to JsonPacker::class.
drivers.consul.client	Optional Consul client settings. Supports uri and token.
drivers.consul.namespaces	An array of Consul KV prefixes to fetch recursively.
drivers.consul.mapping	Maps normalized Consul keys to Hyperf configuration keys. Only mapped keys are applied.
drivers.consul.interval	Pull interval in seconds. Defaults to 5.

If client is omitted or empty, the component reuses Hyperf's bound Hyperf\Consul\KVInterface client. When client is configured, uri defaults to http://127.0.0.1:8500, a non-empty token is sent as the X-Consul-Token header, and the HTTP timeout is 2 seconds.

Behavior

• Every namespace is requested with Consul's recursive option. If namespaces return the same key, the value from the later namespace wins before mapping.
• Consul KV values are Base64-decoded, then passed to the configured packer. With JsonPacker, stored values must contain valid JSON after Base64 decoding.
• Consul keys are normalized to start with / before lookup in mapping.
• The package registers FriendsOfHyperf\ConfigConsul\ClientInterface and FriendsOfHyperf\ConfigConsul\Consul\KVInterface in the container. ConsulDriver is the Config Center driver entry point.
