In DB-less mode, the Admin API for each Kong node functions independently, reflecting the memory state of that particular Kong node. This is the case because there is no database coordination between Kong nodes. In DB-less mode, you configure {{site.base_gateway}} declaratively. Therefore, the Admin API is mostly read-only. The only tasks it can perform are all related to handling the declarative config, including: * [Validating configurations against schemas](#validate-a-configuration-against-a-schema) * [Validating plugin configurations against schemas](#validate-a-plugin-configuration-against-the-schema) * [Reloading the declarative configuration](#reload-declarative-configuration) * [Setting a target's health status in the load balancer](#set-target-as-healthy) ]], }, { title = [[Declarative configuration]], text = [[ Loading the declarative configuration of entities into {{site.base_gateway}} can be done in two ways: at start-up, through the `declarative_config` property, or at run-time, through the Admin API using the `/config` endpoint. To get started using declarative configuration, you need a file (in YAML or JSON format) containing entity definitions. You can generate a sample declarative configuration with the command: ``` kong config init ``` It generates a file named `kong.yml` in the current directory, containing the appropriate structure and examples. ### Reload Declarative Configuration This endpoint allows resetting a DB-less Kong with a new declarative configuration data file. All previous contents are erased from memory, and the entities specified in the given file take their place.

Example: ```json { "config": { "limit": 10, "period": "seconds" } } ``` An example adding a Route to a Service named `test-service`: ``` curl -i -X POST http://localhost:8001/services/test-service/routes \ -H "Content-Type: application/json" \ -d '{"name": "test-route", "paths": [ "/path/one", "/path/two" ]}' ``` - **application/x-www-form-urlencoded** Simple enough for basic request bodies, you will probably use it most of the time. Note that when sending nested values, Kong expects nested objects to be referenced with dotted keys. Example: ``` config.limit=10&config.period=seconds ``` When specifying arrays, send the values in order, or use square brackets (numbering inside the brackets is optional but if provided it must be 1-indexed, and consecutive). An example Route added to a Service named `test-service`: ``` curl -i -X POST http://localhost:8001/services/test-service/routes \ -d "name=test-route" \ -d "paths[1]=/path/one" \ -d "paths[2]=/path/two" ``` The following two examples are identical to the one above, but less explicit: ``` curl -i -X POST http://localhost:8001/services/test-service/routes \ -d "name=test-route" \ -d "paths[]=/path/one" \ -d "paths[]=/path/two" curl -i -X POST http://localhost:8001/services/test-service/routes \ -d "name=test-route" \ -d "paths=/path/one" \ -d "paths=/path/two" ``` - **multipart/form-data** Similar to URL-encoded, this content type uses dotted keys to reference nested objects. Here is an example of sending a Lua file to the pre-function Kong plugin: ``` curl -i -X POST http://localhost:8001/services/plugin-testing/plugins \ -F "name=pre-function" \ -F "config.access=@custom-auth.lua" ``` When specifying arrays for this content-type, the array indices must be specified.

Only `router_flavor` = `traditional` > will support path_handling `"v1'` behavior. `"v0"` is the behavior used in Kong 0.x, 2.x and 3.x. It treats `service.path`, `route.path` and request path as *segments* of a URL. It will always join them via slashes. Given a service path `/s`, route path `/r` and request path `/re`, the concatenated path will be `/s/re`. If the resulting path is a single slash, no further transformation is done to it. If it's longer, then the trailing slash is removed. `"v1"` is the behavior used in Kong 1.x. It treats `service.path` as a *prefix*, and ignores the initial slashes of the request and route paths. Given service path `/s`, route path `/r` and request path `/re`, the concatenated path will be `/sre`. Both versions of the algorithm detect "double slashes" when combining paths, replacing them by single slashes.

When adding a Plugin Configuration to a Service, every request made by a client to that Service will run said Plugin.

But the configuration with which it will run depends on the entities it has been configured for. Plugins can be configured for various entities, combination of entities, or even globally. This is useful, for example, when you wish to configure a plugin a certain way for most requests, but make _authenticated requests_ behave slightly differently. Therefore, there exists an order of precedence for running a plugin when it has been applied to different entities with different configurations. The rule of thumb is: the more specific a plugin is with regards to how many entities it has been configured on, the higher its priority. The complete order of precedence when a plugin has been configured multiple times is: 1. Plugins configured on a combination of: a Route, a Service, and a Consumer. (Consumer means the request must be authenticated). 2. Plugins configured on a combination of a Route and a Consumer. (Consumer means the request must be authenticated). 3. Plugins configured on a combination of a Service and a Consumer. (Consumer means the request must be authenticated). 4. Plugins configured on a combination of a Route and a Service. 5. Plugins configured on a Consumer. (Consumer means the request must be authenticated). 6. Plugins configured on a Route. 7. Plugins configured on a Service. 8. Plugins configured to run globally. **Example**: if the `rate-limiting` plugin is applied twice (with different configurations): for a Service (Plugin config A), and for a Consumer (Plugin config B), then requests authenticating this Consumer will run Plugin config B and ignore A. However, requests that do not authenticate this Consumer will fallback to running Plugin config A.
