APISIX deployment modes
Documentation about the three deployment modes of Apache APISIX.

APISIX has three different deployment modes for different production use cases. The table below summarises the deployment modes:

Deployment mode Roles Description
traditional traditional Data plane and control plane are deployed together. enable_admin attribute should be disabled manually.
decoupled data_plane / control_plane Data plane and control plane are deployed independently.
standalone data_plane Only data_plane is deployed and the configurations are loaded from a local YAML file.

Each of these deployment modes are explained in detail below.

Traditional

In the traditional deployment mode, one instance of APISIX will be both the data_plane and the control_plane.

An example configuration of the traditional deployment mode is shown below:

apisix:
    node_listen:
        - port: 9080
deployment:
    role: traditional
    role_traditional:
        config_provider: etcd
    admin:
        admin_listen:
            port: 9180
    etcd:
       host:
           - http://${etcd_IP}:${etcd_Port}
       prefix: /apisix
       timeout: 30
#END

The instance of APISIX deployed as the traditional role will:

  1. Listen on port 9080 to handle user requests, controlled by node_listen.
  2. Listen on port 9180 to handle Admin API requests, controlled by admin_listen.

Decoupled

In the decoupled deployment mode the data_plane and control_plane instances of APISIX are deployed separately, i.e., one instance of APISIX is configured to be a data plane and the other to be a control plane.

The instance of APISIX deployed as the data plane will:

Once the service is started, it will handle the user requests.

The example below shows the configuration of an APISIX instance as data plane in the decoupled mode:

deployment:
    role: data_plane
    role_data_plane:
       config_provider: etcd
#END

The instance of APISIX deployed as the control plane will:

  1. Listen on port 9180 and handle Admin API requests.

The example below shows the configuration of an APISIX instance as control plane in the decoupled mode:

deployment:
    role: control_plane
    role_control_plane:
        config_provider: etcd
    etcd:
       host:
           - https://${etcd_IP}:${etcd_Port}
       prefix: /apisix
       timeout: 30
#END

Standalone

Turning on the APISIX node in Standalone mode will no longer use the default etcd as the configuration center.

This method is more suitable for two types of users:

  1. Kubernetes(k8s)：Declarative API that dynamically updates the routing rules with a full yaml configuration.
  2. Different configuration centers: There are many implementations of the configuration center, such as Consul, etc., using the full yaml file for intermediate conversion.

The routing rules in the conf/apisix.yaml file are loaded into memory immediately after the APISIX node service starts. And every time interval (default 1 second), will try to detect whether the file content is updated, if there is an update, reload the rule.

Note: Reloading and updating routing rules are all hot memory updates. There is no replacement of working processes, since it's a hot update.

Since the current Admin API is based on the etcd configuration center solution, enable Admin API is not allowed when the Standalone mode is enabled.

Standalone mode can only be enabled when we set the role of APISIX as data plane. We set deployment.role to data_plane and deployment.role_data_plane.config_provider to yaml.

Refer to the example below:

deployment:
  role: data_plane
  role_data_plane:
    config_provider: yaml
#END

How to configure rules

All of the rules are stored in one file which named conf/apisix.yaml, APISIX checks if this file has any change every second. If the file is changed & it ends with #END, APISIX loads the rules from this file and updates its memory.

Here is a mini example:

routes:
  -
    uri: /hello
    upstream:
        nodes:
            "127.0.0.1:1980": 1
        type: roundrobin
#END

WARNING: APISIX will not load the rules into memory from file conf/apisix.yaml if there is no #END at the end.

How to configure Route

Single Route：

routes:
  -
    uri: /hello
    upstream:
        nodes:
            "127.0.0.1:1980": 1
        type: roundrobin
#END

Multiple Routes：

routes:
  -
    uri: /hello
    upstream:
        nodes:
            "127.0.0.1:1980": 1
        type: roundrobin
  -
    uri: /hello2
    upstream:
        nodes:
            "127.0.0.1:1981": 1
        type: roundrobin
#END

How to configure Route + Service

routes:
    -
        uri: /hello
        service_id: 1
services:
    -
        id: 1
        upstream:
            nodes:
                "127.0.0.1:1980": 1
            type: roundrobin
#END

How to configure Route + Upstream

routes:
    -
        uri: /hello
        upstream_id: 1
upstreams:
    -
        id: 1
        nodes:
            "127.0.0.1:1980": 1
        type: roundrobin
#END

How to configure Route + Service + Upstream

routes:
    -
        uri: /hello
        service_id: 1
services:
    -
        id: 1
        upstream_id: 2
upstreams:
    -
        id: 2
        nodes:
            "127.0.0.1:1980": 1
        type: roundrobin
#END

How to configure Plugins

# plugins listed here will be hot reloaded and override the boot configuration
plugins:
  - name: ip-restriction
  - name: jwt-auth
  - name: mqtt-proxy
    stream: true # set 'stream' to true for stream plugins
#END
