Tengine-Ingress 编译

Tengine-Ingress由两部分组成，Tengine-Ingress控制器和Tengine-proxy。Tengine-Ingress控制器是一个基于Tengine-proxy的ingress控制器，在兼容云原生ingress标准规范的基础上扩展了Server，Backend，TLS，Location和Canary。

Tengine-Ingress控制器通过订阅和处理ingress域名资源和secret证书资源，基于tengine ingress模板转换为动态配置写入共享内存。Tengine-proxy订阅共享内存变化写入内部运行时共享内存，将终端用户的外部流量路由到K8s集群中的应用服务。

使用官方镜像

支持操作系统：Anolis, Alpine
支持系统架构：AMD64, ARM64

Anolis

docker pull tengine-ingress-registry.cn-hangzhou.cr.aliyuncs.com/tengine/tengine-ingress:1.1.0

Alpine

docker pull tengine-ingress-registry.cn-hangzhou.cr.aliyuncs.com/tengine/tengine-ingress:1.1.0-alpine

自助编译镜像

第一步：构建tengine镜像

  • Anolis: BASE_IMAGE="docker.io/openanolis/anolisos:latest", LINUX_RELEASE="anolisos"
  • Alpine: BASE_IMAGE="alpine:latest", LINUX_RELEASE="alpine"
    # docker build --no-cache --build-arg BASE_IMAGE="docker.io/openanolis/anolisos:latest" --build-arg LINUX_RELEASE="anolisos" -t tengine:3.1.0 images/tengine/rootfs/

第二步：构建tengine-ingress镜像

在tengine镜像基础上，构建tengine-ingress镜像

# docker build --no-cache --build-arg BASE_IMAGE="tengine:3.1.0" --build-arg VERSION="1.1.0" -f build/Dockerfile -t tengine-ingress:1.1.0 .

最后，使用tengine-ingress镜像部署您的网关。

kind: ConfigMap
metadata:

  namespace: alibaba-ingress-tao

参数名称: --annotations-prefix
默认值: nginx.ingress.kubernetes.io

设置Tengine-Ingress注解的默认前缀，默认前缀为nginx.ingress.kubernetes.io。

参数名称: --v
参数值: ${log_level}

设置Tengine-Ingress的日志级别，日志级别范围1..5，最大日志级别5属于debug模式。

参数名称: --kubeconfig
参数值: ${ing_kubeconfig}

Tengine-Ingress支持K8s core集群与K8s ingress存储集群相隔离的高可靠性部署方案，将运行态和存储态相分离，独立K8s ingress集群可以保证自身API服务器和etcd性能稳定，并且在core集群核心组件API服务器和etcd不可用的高危场景下也能正常向外提供7层转发服务。

参数名称: --watch-namespace
参数值: ${watch_namespace}

设置Tengine-Ingress监听处理的命名空间

  • Tengine-Ingress只监听处理环境变量watch_namespace指定命名空间下的K8s资源对象。
  • K8s资源对象包括Ingress，Secret，Service等相关配置资源。
  • 如果${watch_namespace}`为空，则监听所有命名空间下的资源对象。

参数名称: --controller-class
参数值: ${controller_class}

设置Tengine-Ingress的类别

  • 在Kubernetes 1.19.0及其更高版本，通过IngressClass资源对象定义Ingress资源对象的类别。
  • IngressClass的.spec.controller值与Tengine-Ingress启动参数${controller_class}值保持一致，则Tengine-Ingress才会监听处理对应的Ingress资源对象。
