This article introduces the functions supported by the Apache APISIX Admin API, which you can use to get, create, update, and delete resources.

Description

The Admin API lets users control their deployed Apache APISIX instance. The architecture design gives an idea about how everything fits together.

Configuration

When APISIX is started, the Admin API will listen on port 9180 by default and take the API prefixed with /apisix/admin.

Therefore, to avoid conflicts between your designed API and /apisix/admin, you can modify the configuration file /conf/config.yaml to modify the default listening port.

APISIX supports setting the IP access allowlist of Admin API to prevent APISIX from being illegally accessed and attacked. You can configure the IP addresses to allow access in the deployment.admin.allow_admin option in the ./conf/config.yaml file.

The X-API-KEY shown below refers to the deployment.admin.admin_key.key in the ./conf/config.yaml file, which is the access token for the Admin API.

:::tip

For security reasons, please modify the default admin_key, and check the allow_admin IP access list.

:::

deployment:
    admin:
        admin_key:
        - name: admin
            key: edd1c9f034335f136f87ad84b625c8f1  # using fixed API token has security risk, please update it when you deploy to production environment
            role: admin
        allow_admin:                    # http://nginx.org/en/docs/http/ngx_http_access_module.html#allow
            - 127.0.0.0/24
        admin_listen:
            ip: 0.0.0.0                 # Specific IP, if not set, the default value is `0.0.0.0`.
            port: 9180                  # Specific port, which must be different from node_listen's port.

Using environment variables

To configure via environment variables, you can use the ${{VAR}} syntax. For instance:

deployment:
  admin:
    admin_key:
    - name: admin
      key: ${{ADMIN_KEY}}
      role: admin
    allow_admin:
    - 127.0.0.0/24
    admin_listen:
      ip: 0.0.0.0
      port: 9180

And then run export ADMIN_KEY=$your_admin_key before running make init.

If the configured environment variable can't be found, an error will be thrown.

If you want to use a default value when the environment variable is not set, use ${{VAR:=default_value}} instead. For instance:

deployment:
  admin:
    admin_key:
    - name: admin
      key: ${{ADMIN_KEY:=edd1c9f034335f136f87ad84b625c8f1}}
      role: admin
    allow_admin:
    - 127.0.0.0/24
    admin_listen:
      ip: 0.0.0.0
      port: 9180

This will find the environment variable ADMIN_KEY first, and if it does not exist, it will use edd1c9f034335f136f87ad84b625c8f1 as the default value.

V3 new feature

The Admin API has made some breaking changes in V3 version, as well as supporting additional features.

Support new response body format

  1. Remove action field in response body;
  2. Adjust the response body structure when fetching the list of resources, the new response body structure like:

Return single resource:

{
  "modifiedIndex": 2685183,
  "value": {
    "id": "1",
    ...
  },
  "key": "/apisix/routes/1",
  "createdIndex": 2684956
}

Return multiple resources:

{
  "list": [
    {
      "modifiedIndex": 2685183,
      "value": {
        "id": "1",
        ...
      },
      "key": "/apisix/routes/1",
      "createdIndex": 2684956
    },
    {
      "modifiedIndex": 2685163,
      "value": {
        "id": "2",
        ...
      },
      "key": "/apisix/routes/2",
      "createdIndex": 2685163
    }
  ],
  "total": 2
}

Support paging query

Paging query is supported when getting the resource list, paging parameters include:

parameter Default Valid range Description
page 1 [1, ...] Number of pages.
page_size [10, 500] Number of resources per page.

The example is as follows:

curl "http://127.0.0.1:9180/apisix/admin/routes?page=1&page_size=10" \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X GET
{
  "total": 1,
  "list": [
    {
      ...
    }
  ]
}

Resources that support paging queries:

  • Consumer
  • Consumer Group
  • Global Rules
  • Plugin Config
  • Proto
  • Route
  • Service
  • SSL
  • Stream Route
  • Upstream
  • Secret

Support filtering query

When getting a list of resources, it supports filtering resources based on name, label, uri.

parameter parameter
name Query resource by their name, which will not appear in the query results if the resource itself does not have name.
label Query resource by their label, which will not appear in the query results if the resource itself does not have label.
uri Supported on Route resources only. If the uri of a Route is equal to the uri of the query or if the uris contains the uri of the query, the Route resource appears in the query results.

:::tip

When multiple filter parameters are enabled, use the intersection of the query results for different filter parameters.

:::

The following example will return a list of routes, and all routes in the list satisfy: the name of the route contains the string "test", the uri contains the string "foo", and there is no restriction on the label of the route, since the label of the query is the empty string.

curl 'http://127.0.0.1:9180/apisix/admin/routes?name=test&uri=foo&label=' \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X GET
{
  "total": 1,
  "list": [
    {
      ...
    }
  ]
}

Route

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

Route API

Route resource request address: /apisix/admin/routes/{id}?ttl=0

Request Methods

Method Request URI Request Body Description
GET /apisix/admin/routes NULL Fetches a list of all configured Routes.
GET /apisix/admin/routes/{id} NULL Fetches specified Route by id.
PUT /apisix/admin/routes/{id} {...} Creates a Route with the specified id.
POST /apisix/admin/routes {...} Creates a Route and assigns a random id.
DELETE /apisix/admin/routes/{id} NULL Removes the Route with the specified id.
PATCH /apisix/admin/routes/{id} {...} Updates the selected attributes of the specified, existing Route. To delete an attribute, set value of attribute set to null.

DELETE /apisix/admin/consumers/{username} NULL Removes the Consumer with the specified username.

Request Body Parameters

Parameter Required Type Description Example
username True Name Name of the Consumer.
group_id False Name Group of the Consumer.
plugins False Plugin Plugins that are executed during the request/response cycle. See Plugin for more.
desc False Auxiliary Description of usage scenarios. customer xxxx
labels False Match Rules Attributes of the Consumer specified as key-value pairs. {"version":"v2","build":"16","env":"production"}
create_time False Auxiliary Epoch timestamp (in seconds) of the created time. If missing, this field will be populated automatically. 1602883670
update_time False Auxiliary Epoch timestamp (in seconds) of the updated time. If missing, this field will be populated automatically. 1602883670

Example Configuration:

{
    "plugins": {},          # Bound plugin
    "username": "name",     # Consumer name
    "desc": "hello world"   # Consumer desc
}

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.

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

Response Parameters

Currently, the response is returned from etcd.

Upstream

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.

Upstream API

Upstream resource request address: /apisix/admin/upstreams/{id}

Request Methods

Method Request URI Request Body Description
GET /apisix/admin/upstreams NULL Fetch a list of all configured Upstreams.
GET /apisix/admin/upstreams/{id} NULL Fetches specified Upstream by id.
PUT /apisix/admin/upstreams/{id} {...} Creates an Upstream with the specified id.
POST /apisix/admin/upstreams {...} Creates an Upstream and assigns a random id.
DELETE /apisix/admin/upstreams/{id} NULL Removes the Upstream with the specified id.
PATCH /apisix/admin/upstreams/{id} {...} Updates the selected attributes of the specified, existing Upstream. To delete an attribute, set value of attribute set to null.
PATCH /apisix/admin/upstreams/{id}/{path} {...} Updates the attribute specified in the path. The values of other attributes remain unchanged.

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:

Name Optional Description Example
type optional Load balancing algorithm to be used, and the default value is roundrobin.
nodes required, can't be used with service_name IP addresses (with optional ports) of the Upstream nodes represented as a hash table or an array. In the hash table, the key is the IP address and the value is the weight of the node for the load balancing algorithm. For hash table case, if the key is IPv6 address with port, then the IPv6 address must be quoted with square brackets. In the array, each item is a hash table with keys host, weight, and the optional port and priority. Empty nodes are treated as placeholders and clients trying to access this Upstream will receive a 502 response. 192.168.1.100:80, [::1]:80
service_name required, can't be used with nodes Service name used for service discovery. a-bootiful-client
discovery_type required, if service_name is used The type of service discovery. eureka
hash_on optional Only valid if the type is chash. Supports Nginx variables (vars), custom headers (header), cookie and consumer. Defaults to vars.
key optional Only valid if the type is chash. Finds the corresponding node id according to hash_on and key values. When hash_on is set to vars, key is a required parameter and it supports Nginx variables. When hash_on is set as header, key is a required parameter, and header name can be customized. When hash_on is set to cookie, key is also a required parameter, and cookie name can be customized. When hash_on is set to consumer, key need not be set and the key used by the hash algorithm would be the authenticated consumer_name. If the specified hash_on and key fail to fetch the values, it will default to remote_addr. uri, server_name, server_addr, request_uri, remote_port, remote_addr, query_string, host, hostname, arg_***, arg_***
checks optional Configures the parameters for the health check.
retries optional Sets the number of retries while passing the request to Upstream using the underlying Nginx mechanism. Set according to the number of available backend nodes by default. Setting this to 0 disables retry.
retry_timeout optional Timeout to continue with retries. Setting this to 0 disables the retry timeout.
timeout optional Sets the timeout (in seconds) for connecting to, and sending and receiving messages to and from the Upstream.
name optional Identifier for the Upstream.
desc optional Description of usage scenarios.
pass_host optional Configures the host when the request is forwarded to the upstream. Can be one of pass, node or rewrite. Defaults to pass if not specified. pass- transparently passes the client's host to the Upstream. node- uses the host configured in the node of the Upstream. rewrite- Uses the value configured in upstream_host.
upstream_host optional Specifies the host of the Upstream request. This is only valid if the pass_host is set to rewrite.
scheme optional The scheme used when communicating with the Upstream. For an L7 proxy, this value can be one of http, https, grpc, grpcs. For an L4 proxy, this value could be one of tcp, udp, tls. Defaults to http.
labels optional Attributes of the Upstream specified as key-value pairs. {"version":"v2","build":"16","env":"production"}
create_time optional Epoch timestamp (in seconds) of the created time. If missing, this field will be populated automatically. 1602883670
update_time optional Epoch timestamp (in seconds) of the updated time. If missing, this field will be populated automatically. 1602883670
tls.client_cert optional, can't be used with tls.client_cert_id Sets the client certificate while connecting to a TLS Upstream.
tls.client_key optional, can't be used with tls.client_cert_id Sets the client private key while connecting to a TLS Upstream.
tls.client_cert_id optional, can't be used with tls.client_cert and tls.client_key Set the referenced SSL id.
keepalive_pool.size optional Sets keepalive directive dynamically.
keepalive_pool.idle_timeout optional Sets keepalive_timeout directive dynamically.
keepalive_pool.requests optional Sets keepalive_requests directive dynamically.

An Upstream can be one of the following types:

  • roundrobin: Round robin balancing with weights.
  • chash: Consistent hash.
  • ewma: 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 Nginx variables 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 APISIX-Base:

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.

Or you can reference SSL object by tls.client_cert_id to set SSL cert and key. The SSL object can be referenced only if the type field is client, otherwise the request will be rejected by APISIX. In addition, only cert and key will be used in the SSL object.

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

Create an Upstream and modify the data in nodes

  1. Create upstream

    curl http://127.0.0.1:9180/apisix/admin/upstreams/100  \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -i -X PUT -d '
{
    "type":"roundrobin",
    "nodes":{
        "127.0.0.1:1980": 1
    }
}'
    HTTP/1.1 201 Created
...

  2. Add a node to the Upstream

    curl http://127.0.0.1:9180/apisix/admin/upstreams/100 \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PATCH -i -d '
{
    "nodes": {
        "127.0.0.1:1981": 1
    }
}'
    HTTP/1.1 200 OK
...

    After successful execution, nodes will be updated to:

    {
    "127.0.0.1:1980": 1,
    "127.0.0.1:1981": 1
}

  3. Update the weight of a node to the Upstream

    curl http://127.0.0.1:9180/apisix/admin/upstreams/100 \
-H'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PATCH -i -d '
{
    "nodes": {
        "127.0.0.1:1981": 10
    }
}'
    HTTP/1.1 200 OK
...

    After successful execution, nodes will be updated to:

    {
    "127.0.0.1:1980": 1,
    "127.0.0.1:1981": 10
}

  4. Delete a node for the Upstream

    curl http://127.0.0.1:9180/apisix/admin/upstreams/100 \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PATCH -i -d '
{
    "nodes": {
        "127.0.0.1:1980": null
    }
}'
    HTTP/1.1 200 OK
...

    After successful execution, nodes will be updated to:

    {
    "127.0.0.1:1981": 10
}

  5. Replace the nodes of the Upstream

    curl http://127.0.0.1:9180/apisix/admin/upstreams/100/nodes \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PATCH -i -d '
{
    "127.0.0.1:1982": 1
}'
    HTTP/1.1 200 OK
...

    After the execution is successful, nodes will not retain the original data, and the entire update is:

    {
    "127.0.0.1:1982": 1
}

Proxy client request to https Upstream service

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

    curl -i http://127.0.0.1:9180/apisix/admin/routes/1 \
-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
{
    "uri": "/get",
    "upstream": {
        "type": "roundrobin",
        "scheme": "https",
        "nodes": {
            "httpbin.org:443": 1
        }
    }
}'

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

  2. 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.
