Admin API

Description

The Admin API is a group of APIs served for the Apache APISIX, we could pass parameters to APIs to control APISIX Nodes. To have a better understanding about how it works, please see the architecture design.

When Apache APISIX launches, the Admin API will listen on 9080 port by default (9443 port for HTTPS). You could take another port by modifying the conf/config.yaml file.

The X-API-KEY appearing below refers to the apisix.admin_key.key in the conf/config.yaml file, which is the access token of the Admin API.

Route

API：/apisix/admin/routes/{id}?ttl=0

Description：Route matches requests based on preset rules, and loads the appropriate plugin according to the matching result, then forwarding requests to target Upstream.

Note: When the Admin API is enabled, it will occupy the API prefixed with /apisix/admin. Therefore, in order to avoid conflicts between your design API and /apisix/admin, it is recommended to use a different port for the Admin API. You can customize the Admin API port through port_admin in conf/config.yaml.

Request Methods

Method	Request URI	Request Body	Description
GET	/apisix/admin/routes	NULL	Fetch resource list
GET	/apisix/admin/routes/{id}	NULL	Fetch resource
PUT	/apisix/admin/routes/{id}	{...}	Create resource by ID
POST	/apisix/admin/routes	{...}	Create resource, and ID is generated by server
DELETE	/apisix/admin/routes/{id}	NULL	Remove resource
PATCH	/apisix/admin/routes/{id}	{...}	Standard PATCH. Update some attributes of the existing Route, and other attributes not involved will remain as they are; if you want to delete an attribute, set the value of the attribute Set to null to delete; especially, when the value of the attribute is an array, the attribute will be updated in full
PATCH	/apisix/admin/routes/{id}/{path}	{...}	SubPath PATCH, specify the attribute of Route to be updated through {path}, update the value of this attribute in full, and other attributes that are not involved will remain as they are. The difference between the two PATCH can refer to the following examples

URI Request Parameters

parameter	Required	Type	Description	Example
ttl	False	Auxiliary	Expires after target seconds	ttl=1

Request Body Parameters

Parameter	Required	Type	Description	Example
name	False	Auxiliary	Identifies route names.	route-xxxx
desc	False	Auxiliary	route description, usage scenarios, and more.	route xxxx
uri	True, can't be used with `uris`	Match Rules	In addition to full matching such as `/foo/bar`、`/foo/gloo`, using different Router allows more advanced matching, see Router for more.	"/hello"
uris	True, can't be used with `uri`	Match Rules	The `uri` in the form of a non-empty list means that multiple different uris are allowed, and match any one of them.	["/hello", "/word"]
host	False, can't be used with `hosts`	Match Rules	Currently requesting a domain name, such as `foo.com`; PAN domain names such as `*.foo.com` are also supported.	"foo.com"
hosts	False, can't be used with `host`	Match Rules	The `host` in the form of a non-empty list means that multiple different hosts are allowed, and match any one of them.	["foo.com", "*.bar.com"]
remote_addr	False, can't be used with `remote_addrs`	Match Rules	The client requests an IP address: `192.168.1.101`, `192.168.1.102`, and CIDR format support `192.168.1.0/24`. In particular, APISIX also fully supports IPv6 address matching: `::1`, `fe80::1`, `fe80::1/64`, etc.	"192.168.1.0/24"
remote_addrs	False, can't be used with `remote_addr`	Match Rules	The `remote_addr` in the form of a non-empty list indicates that multiple different IP addresses are allowed, and match any one of them.	["127.0.0.1", "192.0.0.0/8", "::1"]
methods	False	Match Rules	If empty or without this option, there are no `method` restrictions, and it can be a combination of one or more: `GET`,`POST`,`PUT`,`DELETE`,`PATCH`, `HEAD`,`OPTIONS`,`CONNECT`,`TRACE`.	["GET", "POST"]
priority	False	Match Rules	If different routes contain the same `uri`, determine which route is matched first based on the attribute `priority`. Larger value means higher priority. The default value is 0.	priority = 10
vars	False	Match Rules	A list of one or more `[var, operator, val]` elements, like this: `[[var, operator, val], [var, operator, val], ...]]`. For example: `["arg_name", "==", "json"]` means that the current request parameter `name` is `json`. The `var` here is consistent with the internal variable name of Nginx, so you can also use `request_uri`, `host`, etc. For more details, see lua-resty-expr	[["arg_name", "==", "json"], ["arg_age", ">", 18]]
filter_func	False	Match Rules	User-defined filtering function. You can use it to achieve matching requirements for special scenarios. This function accepts an input parameter named `vars` by default, which you can use to get Nginx variables.	function(vars) return vars["arg_name"] == "json" end
plugins	False	Plugin	See Plugin for more
script	False	Script	See Script for more
upstream	False	Upstream	Enabled Upstream configuration, see Upstream for more
upstream_id	False	Upstream	Enabled upstream id, see Upstream for more
service_id	False	Service	Bound Service configuration, see Service for more
plugin_config_id	False, can't be used with `script`	Plugin	Bound plugin config object, see Plugin Config for more
labels	False	Match Rules	Key/value pairs to specify attributes	{"version":"v2","build":"16","env":"production"}
timeout	False	Auxiliary	Set the upstream timeout for connecting, sending and receiving messages of the route. This option will overwrite the timeout option which set in upstream configuration.	{"connect": 3, "send": 3, "read": 3}
enable_websocket	False	Auxiliary	enable `websocket`(boolean), default `false`.
status	False	Auxiliary	enable this route, default `1`.	`1` to enable, `0` to disable
create_time	False	Auxiliary	epoch timestamp in second, will be created automatically if missing	1602883670
update_time	False	Auxiliary	epoch timestamp in second, will be created automatically if missing	1602883670

There are two points that need special attention:

For the same type of parameters, such as host and hosts, remote_addr and remote_addrs cannot exist at the same time, only one of them can be selected. If enabled at the same time, the API will respond with an error.
In vars, when getting the cookie value, the cookie name is case-sensitive. For example: var equals "cookie_x_foo" and var equals "cookie_X_Foo" means different cookie.

Config Example:

{
    "id": "1",                  # id, unnecessary.
    "uris": ["/a","/b"],        # A set of uri.
    "methods": ["GET","POST"],  # Can fill multiple methods
    "hosts": ["a.com","b.com"], # A set of host.
    "plugins": {},              # Bound plugin
    "priority": 0,              # If different routes contain the same `uri`, determine which route is matched first based on the attribute` priority`, the default value is 0.
    "name": "route-xxx",
    "desc": "hello world",
    "remote_addrs": ["127.0.0.1"], # A set of Client IP.
    "vars": [["http_user", "==", "ios"]], # A list of one or more `[var, operator, val]` elements
    "upstream_id": "1",         # upstream id, recommended
    "upstream": {},             # upstream, not recommended
    "timeout": {                # Set the upstream timeout for connecting, sending and receiving messages of the route.
        "connect": 3,
        "send": 3,
        "read": 3
    },
    "filter_func": "",          # User-defined filtering function
}

Consumer

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

Description：Consumers are consumers of certain types of services and can only be used in conjunction with a user authentication system. Consumer regards the username property as the identity, so only the HTTP PUT method is supported for creating a new consumer.

Request Methods

Method	Request URI	Request Body	Description
GET	/apisix/admin/consumers	NULL	Fetch resource list
GET	/apisix/admin/consumers/{username}	NULL	Fetch resource
PUT	/apisix/admin/consumers	{...}	Create resource by username
DELETE	/apisix/admin/consumers/{username}	NULL	Remove resource

Request Body Parameters

Parameter	Required	Type	Description	Example
username	True	Name	Consumer name
plugins	False	Plugin	See Plugin for more
desc	False	Auxiliary	Identifies route names, usage scenarios, and more.	customer xxxx
labels	False	Match Rules	Key/value pairs to specify attributes	{"version":"v2","build":"16","env":"production"}
create_time	False	Auxiliary	epoch timestamp in second, will be created automatically if missing	1602883670
update_time	False	Auxiliary	epoch timestamp in second, will be created automatically if missing	1602883670

Config Example:

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

The binding authentication plug-in is a bit special. When it needs to be used in conjunction with the consumer, it needs to provide user name, password and other information; on the other hand, when it is bound with route / service, it does not require any parameters. Because at this time, it is based on the user request data to infer which consumer the user corresponds to.

Example:

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

            "count": 2,
            "time_window": 60,
            "rejected_code": 503,
            "key": "remote_addr"
        }
    }
}'

Upstream

API：/apisix/admin/upstreams/{id}

Description：Upstream configuration can be directly bound to the specified Route or it can be bound to Service, but the configuration in Route has a higher priority. The priority behavior here is very similar to Plugin.

Request Methods

Method	Request URI	Request Body	Description
GET	/apisix/admin/upstreams	NULL	Fetch resource list
GET	/apisix/admin/upstreams/{id}	NULL	Fetch resource
PUT	/apisix/admin/upstreams/{id}	{...}	Create resource by ID
POST	/apisix/admin/upstreams	{...}	Create resource, and ID is generated by server
DELETE	/apisix/admin/upstreams/{id}	NULL	Remove resource
PATCH	/apisix/admin/upstreams/{id}	{...}	Standard PATCH. Update some attributes of the existing Upstream, and other attributes not involved will remain as they are; if you want to delete an attribute, set the value of the attribute Set to null to delete; especially, when the value of the attribute is an array, the attribute will be updated in full
PATCH	/apisix/admin/upstreams/{id}/{path}	{...}	SubPath PATCH, specify the attribute of Upstream to be updated through {path}, update the value of this attribute in full, and other attributes that are not involved will remain as they are. The difference between the two PATCH can refer to the following example

Request Body Parameters

In addition to the basic complex equalization algorithm selection, APISIX's Upstream also supports logic for upstream passive health check and retry, see the table below.

Name	Optional	Description	Example
type	required	the balancer algorithm
nodes	required, can't be used with `service_name`	Hash table or array. If it is a hash table, the key of the internal element is the upstream machine address list, the format is `Address + (optional) Port`, where the address part can be IP or domain name, such as `192.168.1.100:80`, `foo.com:80`, etc. The value is the weight of node. If it is an array, each item is a hash table with key `host`/`weight` and optional `port`/`priority`. The `nodes` can be empty, which means it is a placeholder and will be filled later. Clients use such an upstream will get 502 response.	`192.168.1.100:80`
service_name	required, can't be used with `nodes`	the name of service used in the service discovery, see discovery for more details	`a-bootiful-client`
discovery_type	required, if `service_name` is used	the type of service discovery, see discovery for more details	`eureka`
hash_on	optional	This option is only valid if the `type` is `chash`. Supported types `vars`(Nginx variables), `header`(custom header), `cookie`, `consumer`, the default value is `vars`.
key	optional	This option is only valid if the `type` is `chash`. Find the corresponding node `id` according to `hash_on` and `key`. When `hash_on` is set as `vars`, `key` is the required parameter, for now, it support nginx built-in variables like `uri, server_name, server_addr, request_uri, remote_port, remote_addr, query_string, host, hostname, arg_*`, `arg_*` is arguments in the request line, Nginx variables list. When `hash_on` is set as `header`, `key` is the required parameter, and `header name` is customized. When `hash_on` is set to `cookie`, `key` is the required parameter, and `cookie name` is customized. When `hash_on` is set to `consumer`, `key` does not need to be set. In this case, the `key` adopted by the hash algorithm is the `consumer_name` authenticated. If the specified `hash_on` and `key` can not fetch values, it will be fetch `remote_addr` by default.
checks	optional	Configure the parameters of the health check. For details, refer to health-check.
retries	optional	Pass the request to the next upstream using the underlying Nginx retry mechanism, the retry mechanism is enabled by default and set the number of retries according to the number of available backend nodes. If `retries` option is explicitly set, it will override the default value. `0` means disable retry mechanism.
retry_timeout	optional	Configure a number to limit the amount of seconds that retries can be continued, and do not continue retries if the previous request and retry requests have taken too long. `0` means disable retry timeout mechanism.
timeout	optional	Set the timeout for connecting, sending and receiving messages.
name	optional	Identifies upstream names
desc	optional	upstream usage scenarios, and more.
pass_host	optional	`host` option when the request is sent to the upstream, can be one of [`pass`, `node`, `rewrite`], the default option is `pass`. `pass`: Pass the client's host transparently to the upstream; `node`: Use the host configured in the node of `upstream`; `rewrite`: Use the value of the configuration `upstream_host`.
upstream_host	optional	Specify the host of the upstream request. This option is only valid if the `pass_host` is `rewrite`.
scheme	optional	The scheme used when talk with the upstream. For L7 proxy, the value is one of ['http', 'https', 'grpc', 'grpcs']. For L7 proxy, the value is one of ['tcp', 'udp', 'tls']. Default to 'http'. See below for more details.
labels	optional	Key/value pairs to specify attributes	{"version":"v2","build":"16","env":"production"}
create_time	optional	epoch timestamp in second, like `1602883670`, will be created automatically if missing	1602883670
update_time	optional	epoch timestamp in second, like `1602883670`, will be created automatically if missing	1602883670
tls.client_cert	optional	Set the client certificate when connecting to TLS upstream, see below for more details
tls.client_key	optional	Set the client private key when connecting to TLS upstream, see below for more details
keepalive_pool.size	optional	Set `keepalive` directive dynamically, see below for more details
keepalive_pool.idle_timeout	optional	Set `keepalive_timeout` directive dynamically, see below for more details
keepalive_pool.requests	optional	Set `keepalive_requests` directive dynamically, see below for more details

type can be one of:

roundrobin: roundrobin with weight
chash: consistent hash
ewma: pick one of node which has minimum latency. See https://en.wikipedia.org/wiki/EWMA_chart for details.
least_conn: pick node which has the lowest (active_conn + 1) / weight. Note the active connection concept is the same with Nginx: it is a connection in used by a request.
user-defined balancer which can be loaded via require("apisix.balancer.your_balancer").

hash_on can be set to different types:

When it is vars, the key is required. The key can be any Nginx builtin variables, without the prefix '$'.
When it is header, the key is required. It is equal to "http_key".
When it is cookie, the key is required. It is equal to "cookie_key". Please note that the cookie name is case-sensitive. For example: "cookie_x_foo" and "cookie_X_Foo" indicate different cookie.
When it is consumer, the key is optional. The key is the consumer_name set by authentication plugin.
When it is vars_combinations, the key is required. The key can be any Nginx builtin variables combinations, such as $request_uri$remote_addr.
If there is no value for either hash_on or key, remote_addr will be used as key.

Features below require APISIX to run on APISIX-OpenResty:

The scheme can be set to tls, which actually means "TLS over TCP".

tls.client_cert/key can be used to communicate with upstream via mTLS. Their formats are the same as SSL's cert and key fields.

keepalive_pool allows the upstream to have its separate connection pool. Its children fields, like requests, can be used to configure the upstream keepalive options.

Config Example:

{
    "id": "1",                  # id
    "retries": 1,               # retry times
    "timeout": {                # Set the timeout for connecting, sending and receiving messages.
        "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:

Example 1: Create an upstream and modify the data of nodes

# Create upstream
$ curl http://127.0.0.1:9080/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
...


# Add a node to the Upstream
$ curl http://127.0.0.1:9080/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
}


# Update the weight of a node to the Upstream
$ curl http://127.0.0.1:9080/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
}


# Delete a node for the Upstream
$ curl http://127.0.0.1:9080/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
}


# Replace the nodes of the Upstream
$ curl http://127.0.0.1:9080/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
}

Example 2: How to proxy client request to https upstream service

Create a route and configure the upstream scheme as https.

$ curl -i http://127.0.0.1:9080/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 the execution is successful, the scheme when requesting to communicate with the upstream will be https.

Send a request for testing.

$ 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, which means 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 are unavailable or tried.

As the default priority is 0, we can configure nodes with negative priority as the 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 unavailable or tried. Therefore, it is the backup of 127.0.0.1.
