Admin API

By default, the Admin API listens to port (9443 for HTTPS) when APISIX is launched. This can be changed by modifying your configuration file (conf/config.yaml).

Note: Mentions of X-API-KEY in this document refers to apisix.admin_key.key—the access token for Admin API—in your configuration file.

API: /apisix/admin/routes/{id}?ttl=0

Routes match the client’s request based on defined rules, loads and executes the corresponding , and forwards the request to the specified Upstream.

Note: When the Admin API is enabled, to avoid conflicts with your design API, use a different port for the Admin API. This can be set in your configuration file by changing the port_admin key.

Service

API: /apisix/admin/services/{id}

A Service is an abstraction of an API (which can also be understood as a set of Route abstractions). It usually corresponds to an upstream service abstraction.

The relationship between Routes and a Service is usually N:1.

Consumer

API: /apisix/admin/consumers/{username}

Consumers are users of services and can only be used in conjunction with a user authentication system. A Consumer is identified by a username property. So, for creating a new Consumer, only the HTTP PUT method is supported.

Request Methods

Request Body Parameters

Example Configuration:

When bound to a Route or Service, the Authentication Plugin infers the Consumer from the request and does not require any parameters. Whereas, when it is bound to a Consumer, username, password and other information needs to be provided.

Example API usage:

$ curl http://127.0.0.1:9080/apisix/admin/consumers  -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '

    "username": "jack",
    "plugins": {
        "key-auth": {
            "key": "auth-one"
        },
        "limit-count": {
            "count": 2,
            "time_window": 60,
            "rejected_code": 503,
            "key": "remote_addr"
        }
    }
}'
HTTP/1.1 200 OK

Since v2.2, we can bind multiple authentication plugins to the same consumer.

Back to TOC

API: /apisix/admin/upstreams/{id}

Upstream is a virtual host abstraction that performs load balancing on a given set of service nodes according to the configured rules.

An Upstream configuration can be directly bound to a Route or a Service, but the configuration in Route has a higher priority. This behavior is consistent with priority followed by the Plugin object.

Request Methods

Request Body Parameters

In addition to the equalization algorithm selections, Upstream also supports passive health check and retry for the upstream. See the table below for more details:

An Upstream can be one of the following types:

• roundrobin: Round robin balancing with weights.
• chash: Consistent hash.
• : Pick the node with minimum latency. See EWMA Chart for more details.
• least_conn: Picks the node with the lowest value of (active_conn + 1) / weight. Here, an active connection is a connection being used by the request and is similar to the concept in Nginx.
• user-defined load balancer loaded via require("apisix.balancer.your_balancer").

The following should be considered when setting the hash_on value:

• When set to vars, a key is required. The value of the key can be any of the without the $ prefix.
• When set to header, a key is required. This is equal to “http_key“.
• When set to cookie, a key is required. This key is equal to “cookie_key“. The cookie name is case-sensitive.
• When set to consumer, the key is optional and the key is set to the consumer_name captured from the authentication Plugin.
• When set to vars_combinations, the key is required. The value of the key can be a combination of any of the Nginx variables like $request_uri$remote_addr.
• When no value is set for either hash_on or key, the key defaults to remote_addr.

The features described below requires APISIX to be run on :

You can set the scheme to tls, which means “TLS over TCP”.

To use mTLS to communicate with Upstream, you can use the tls.client_cert/key in the same format as SSL’s cert and key fields.

To allow Upstream to have a separate connection pool, use keepalive_pool. It can be configured by modifying its child fields.

Example Configuration:

{
    "id": "1",                  # id
    "retries": 1,               # retry times
    "timeout": {                # Set the timeout for connecting, sending and receiving messages, each is 15 seconds.
        "connect":15,
        "send":15,
        "read":15,
    },
    "nodes": {"host:80": 100},  # Upstream machine address list, the format is `Address + Port`
                                # is the same as "nodes": [ {"host": "host", "port": 80, "weight": 100} ],
    "type":"roundrobin",
    "checks": {},               # Health check parameters
    "hash_on": "",
    "key": "",
    "name": "upstream-for-test",
    "desc": "hello world",
    "scheme": "http",           # The scheme used when communicating with upstream, the default is `http`
}

Example API usage:

After the execution is successful, nodes will not retain the original data, and the entire update is:
{
    "127.0.0.1:1982": 1
}

Example 2: Proxy client request to https Upstream service

1. Create a route and configure the upstream scheme as https.

After successful execution, the scheme when requesting to communicate with the upstream will be https.

1. Send a request to test.

$ curl http://127.0.0.1:9080/get
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Host": "127.0.0.1",
    "User-Agent": "curl/7.29.0",
    "X-Amzn-Trace-Id": "Root=1-6058324a-0e898a7f04a5e95b526bb183",
    "X-Forwarded-Host": "127.0.0.1"
  },
  "origin": "127.0.0.1",
  "url": "https://127.0.0.1/get"
}

The request is successful, meaning that the proxy Upstream https is valid.

Note:

Each node can be configured with a priority. A node with low priority will only be used when all the nodes with higher priority have been tried or are unavailable.

As the default priority is 0, nodes with negative priority can be configured as a backup.

For example:

{
  "uri": "/hello",
  "upstream": {
    "type": "roundrobin",
    "nodes": [
      { "host": "127.0.0.1", "port": 1980, "weight": 2000 },
      { "host": "127.0.0.1", "port": 1981, "weight": 1, "priority": -1 }
    ],
    "checks": {
      "active": {
        "http_path": "/status",
        "healthy": {
          "interval": 1,
          "successes": 1
        },
        "unhealthy": {
          "interval": 1,
          "http_failures": 1
        }
      }
    }
  }
}

Node 127.0.0.2 will be used only after 127.0.0.1 is tried or unavailable. It can therefore act as a backup for the node 127.0.0.1.
