# Kong configuration file
# -----------------------
# The commented-out settings shown in this file represent the default values.
# This file is read when `kong start` or `kong prepare` are used. Kong
# generates the Nginx configuration with the settings specified in this file.
# All environment variables prefixed with `KONG_` and capitalized will override
# the settings specified in this file.
# Example:
#   `log_level` setting -> `KONG_LOG_LEVEL` env variable
# Boolean values can be specified as `on`/`off` or `true`/`false`.
# Lists must be specified as comma-separated strings.
# All comments in this file can be removed safely, including the
# commented-out properties.
# You can verify the integrity of your settings with `kong check <conf>`.

# NGINX injected directives
#------------------------------------------------------------------------------
# Nginx directives can be dynamically injected in the runtime nginx.conf file
# without requiring a custom Nginx configuration template.
# All configuration properties respecting the naming scheme
# `nginx_<namespace>_<directive>` will result in `<directive>` being injected in
# the Nginx configuration block corresponding to the property's `<namespace>`.
# Example:
#   `nginx_proxy_large_client_header_buffers = 8 24k`
#   Will inject the following directive in Kong's proxy `server {}` block:
#   `large_client_header_buffers 8 24k;`
# The following namespaces are supported:
# - `nginx_main_<directive>`: Injects `<directive>` in Kong's configuration
#   `main` context.
# - `nginx_events_<directive>`: Injects `<directive>` in Kong's `events {}`
#    block.
# - `nginx_http_<directive>`: Injects `<directive>` in Kong's `http {}` block.
# - `nginx_proxy_<directive>`: Injects `<directive>` in Kong's proxy
#   `server {}` block.
# - `nginx_upstream_<directive>`: Injects `<directive>` in Kong's proxy
#   `upstream {}` block.
# - `nginx_admin_<directive>`: Injects `<directive>` in Kong's Admin API
#   `server {}` block.
# - `nginx_status_<directive>`: Injects `<directive>` in Kong's Status API
#   `server {}` block  (only effective if `status_listen` is enabled).
# - `nginx_stream_<directive>`: Injects `<directive>` in Kong's stream module
#   `stream {}` block (only effective if `stream_listen` is enabled).
# - `nginx_sproxy_<directive>`: Injects `<directive>` in Kong's stream module
#   `server {}` block (only effective if `stream_listen` is enabled).
# - `nginx_supstream_<directive>`: Injects `<directive>` in Kong's stream
#   module `upstream {}` block.
# As with other configuration properties, Nginx directives can be injected via
# environment variables when capitalized and prefixed with `KONG_`.
# Example:
#   `KONG_NGINX_HTTP_SSL_PROTOCOLS` -> `nginx_http_ssl_protocols`
#   Will inject the following directive in Kong's `http {}` block:
#   `ssl_protocols <value>;`
#   If different sets of protocols are desired between the proxy and Admin API
#   server, you may specify `nginx_proxy_ssl_protocols` and/or
#   `nginx_admin_ssl_protocols`, both of which taking precedence over the
#   `http {}` block.

# a cluster, or without a database, where each node stores its information
# independently in memory.
# When using a database, Kong will store data for all its entities (such as
# Routes, Services, Consumers, and Plugins) in either Cassandra or PostgreSQL,
# and all Kong nodes belonging to the same cluster must connect themselves
# to the same database.
# Kong supports the following database versions:
# - **PostgreSQL**: 9.5 and above.
# - **Cassandra**: 2.2 and above.
# When not using a database, Kong is said to be in "DB-less mode": it will keep
# its entities in memory, and each node needs to have this data entered via a
# declarative configuration file, which can be specified through the
# `declarative_config` property, or via the Admin API using the `/config`
# endpoint.
# When using Postgres as the backend storage, you can optionally enable Kong
# to serve read queries from a separate database instance.
# When the number of proxies is large, this can greatly reduce the load
# on the main Postgres instance and achieve better scalability. It may also
# reduce the latency jitter if the Kong proxy node's latency to the main
# Postgres instance is high.
# The read-only Postgres instance only serves read queries and write
# queries still goes to the main connection. The read-only Postgres instance
# can be eventually consistent while replicating changes from the main
# instance.
# At least the `pg_ro_host` config is needed to enable this feature.
# By default, all other database config for the read-only connection are
# inherited from the corresponding main connection config described above but
# may be optionally overwritten explicitly using the `pg_ro_*` config below.

# DNS RESOLVER
#------------------------------------------------------------------------------

# `/etc/hosts` and `/etc/resolv.conf`. The settings in the latter file will be
# overridden by the environment variables `LOCALDOMAIN` and `RES_OPTIONS` if
# they have been set.
# Kong will resolve hostnames as either `SRV` or `A` records (in that order, and
# `CNAME` records will be dereferenced in the process).
# In case a name was resolved as an `SRV` record it will also override any given
# port number by the `port` field contents received from the DNS server.
# The DNS options `SEARCH` and `NDOTS` (from the `/etc/resolv.conf` file) will
# be used to expand short names to fully qualified ones. So it will first try
# the entire `SEARCH` list for the `SRV` type, if that fails it will try the
# `SEARCH` list for `A`, etc.
# For the duration of the `ttl`, the internal DNS resolver will loadbalance each
# request it gets over the entries in the DNS record. For `SRV` records the
# `weight` fields will be honored, but it will only use the lowest `priority`
# field entries in the record.

# DATABASE ENCRYPTION & KEYRING MANAGEMENT
#-------------------------------------------------------------------------------
# When enabled, Kong will transparently encrypt sensitive fields, such as Consumer
# credentials, TLS private keys, and RBAC user tokens, among others. A full list
# of encrypted fields is available from the Kong Enterprise documentation site.
# Encrypted data is transparently decrypted before being displayed to the Admin
# API or made available to plugins or core routing logic.
# While this feature is GA, do note that we currently do not provide normal semantic
# versioning compatibility guarantees on the keyring feature's APIs in that Kong may
# make a breaking change to the feature in a minor version. Also note that
# mis-management of keyring data may result in irrecoverable data loss.

# NGINX 注入指令
#------------------------------------------------ -----------------------------------------
# Nginx 指令可以动态注入到运行时的 nginx.conf 文件中
# 无需自定义 Nginx 配置模板。
# 所有关于命名方案的配置属性
# `nginx_<namespace>_<directive>` 将导致 `<directive>` 被注入# 对应属性的`<namespace>`的Nginx配置块。
# 例子:
# `nginx_proxy_large_client_header_buffers = 8 24k`
# 将在 Kong 的代理 `server {}` 块中注入以下指令:
# `large_client_header_buffers 8 24k;`
# 支持以下命名空间:
# - `nginx_main_<directive>`: 在 Kong 的配置中注入 `<directive>`
# `main` 上下文。
# - `nginx_events_<directive>`:在 Kong 的 `events {}` 中注入 `<directive>`
#    堵塞。
# - `nginx_http_<directive>`:在 Kong 的 `http {}` 块中注入 `<directive>`。
# - `nginx_proxy_<directive>`: 在 Kong 的代理中注入 `<directive>`
# `server {}` 块。
# - `nginx_upstream_<directive>`: 在 Kong 的代理中注入 `<directive>`
# `上游{}`块。
# - `nginx_admin_<directive>`: 在 Kong 的 Admin API 中注入 `<directive>`
# `server {}` 块。
# - `nginx_status_<directive>`:在 Kong 的 Status API 中注入 `<directive>`
# `server {}` 块(仅在启用 `status_listen` 时有效)。
# - `nginx_stream_<directive>`: 在 Kong 的流模块中注入 `<directive>`
# `stream {}` 块(仅在启用 `stream_listen` 时有效)。
# - `nginx_sproxy_<directive>`: 在 Kong 的流模块中注入 `<directive>`
# `server {}` 块(仅在启用 `stream_listen` 时有效)。
# - `nginx_supstream_<directive>`: 在 Kong 的流中注入 `<directive>`
# 模块`上游{}`块。
# 与其他配置属性一样,Nginx 指令可以通过
# 环境变量大写并以 `KONG_` 为前缀。
# 例子:
# `KONG_NGINX_HTTP_SSL_PROTOCOLS` -> `nginx_http_ssl_protocols`
# 将在 Kong 的 `http {}` 块中注入以下指令:
# `ssl_protocols <值>;`
# 如果代理和管理 API 之间需要不同的协议集
# 服务器,你可以指定 `nginx_proxy_ssl_protocols` 和/或
# `nginx_admin_ssl_protocols`,两者都优先于
# `http {}` 块。

# 数据存储
#------------------------------------------------ -----------------------------------------
# Kong 可以与数据库一起运行,以将 Kong 节点之间的协调数据存储在
# 一个集群,或者没有数据库,每个节点都存储它的信息
# 在内存中独立。
# 当使用数据库时,Kong 将存储其所有实体的数据(例如
# 路由、服务、消费者和插件)在 Cassandra 或 PostgreSQL 中,
# 并且属于同一个集群的所有Kong节点必须自己连接
# 到同一个数据库。
# Kong 支持以下数据库版本:
# - **PostgreSQL**:9.5 及更高版本。
# - **Cassandra**:2.2 及更高版本。
# 当不使用数据库时,Kong 处于“DB-less 模式”:它将保持
# 它在内存中的实体,每个节点都需要通过一个
# 声明式配置文件,可以通过
# `declarative_config` 属性,或通过使用 `/config` 的 Admin API
# 使用 Postgres 作为后端存储时,可以选择启用 Kong
# 提供来自单独数据库实例的读取查询。
# 当代理数量很大时,这样可以大大减少负载
# 在主 Postgres 实例上实现更好的可扩展性。它也可能
# 如果 Kong 代理节点延迟到主节点,则减少延迟抖动
# Postgres 实例很高。
# 只读的 Postgres 实例只服务于读查询和写
# 查询仍会转到主连接。只读 Postgres 实例
# 在从主目录复制更改时可以最终保持一致
# 实例。
# 至少需要 `pg_ro_host` 配置来启用此功能。

# 继承自上述相应的主连接配置,但是

个人理解,仅供参考: 首先,kong+konga除去其他高级功能,个人觉得就是把nginx,变成可以页面配置的了。比如,配置的router,service就是反向代理,配置upstream就是负载均衡。 本文只介绍KONGA配置service,router,upstream。 使用docker-compose安装: docker-compose.yml [root@ecs-f841-0003 kong]# cat docker-compose.yml version: '3' services:

Kong 是一个开源的云原生 API 网关,它可以用来管理和路由 API 请求。与此同时,Nginx 是一个高性能的 Web 服务器和反向代理服务器。在配置 Kong 和 Nginx 时,你需要将 Kong 配置为 Nginx 的插件,并将其与 Nginx 进行集成。 下面是一个简单的示例配置,展示了如何将 Kong 配置为 Nginx 的插件: 1. 首先,确保你已经安装了 Nginx 和 Kong。 2. 打开 Nginx 的配置文件,通常位于 `/etc/nginx/nginx.conf`。在 `http` 块中添加以下内容: http { # ...其他配置... # 启用 HTTP 代理模块 proxy_http_version 1.1; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; # 配置 Kong 的代理 location / { proxy_pass http://localhost:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; # 配置 Kong 的 Admin API location /kong { proxy_pass http://localhost:8001; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; # ...其他配置... 上述配置中,我们首先启用了 HTTP 代理模块,然后为 Kong 的代理和 Admin API 分别配置了对应的 `location`。 3. 保存并退出 Nginx 配置文件。 4. 启动 Nginx 和 Kong,并确保它们都正常运行。 这只是一个简单的示例配置,你可以根据自己的需求进行更详细的配置。另外,Kong 还提供了更多高级功能和插件,你可以根据文档进一步了解和配置
