Techniques to address common Istio traffic management and network problems. cluster. Usage Istio Gateway cert-manager can be used to write a secret to Kubernetes, which can then be referenced by a Gateway. Deploy secure ingress gateway for Istio service mesh add-on for Azure Kubernetes Service. Istio 通过名为“自动 mTLS” 的功能使得配置更改容易。自动 mTLS 将原理如下：如果在 DestinationRule 中没有明确配置 TLS 设置，Sidecar 将会自动选择是否发送 Istio 双向 TLS。这意味着没有任何配置，所有网格内部的流量将会被 mTLS 加密。网关 Istio supports the Kubernetes Gateway API and intends to make it the default API for traffic management in the future. Istio requires us to use a Policy object to instruct a service, namespace, or mesh to receive mTLS traffic. If you are NOT using the Gateway API instructions, make sure to deploy the Istio egress gateway. To get started, configure an Issuer resource, following the cert-manager issuer documentation 7 . Describes how to configure the Kubernetes Gateway API with Istio. yaml │ ├── api-destinationrule. The difference is that the client of an ingress gateway is running outside of the mesh while in the case of an egress gateway, the destination is outside of the mesh. Configuration Consult the cert-manager installation documentation to get started. Shows you how to incrementally migrate your Istio services to mutual TLS. g. Unlike traditional Ingress controllers, Gateway API provides a more expressive, extensible, and The goal of this blog post is to demonstrate how you can expose an OpenTelemetry (OTel) Collector running inside Kubernetes to the outside world securely, using the Kubernetes Gateway API and mutual TLS (mTLS) for authentication and encryption. e. so in this case traffic flow will be "External traffic" <---mTLS--> istio-ingress gateway<--mTLS-->istio-proxy inside pod (sidecar)<--pain text--> Applicaiton Container. local), as well as route from the gateway to the external service. Deploy services into the mesh, and configure mutual TLS (mTLS) to secure service-to-service communication. Just deployed my first service mesh and I'm still processing what I just learned! Spent the last few days setting up Istio's ambient mode on my local k3d cluster, and honestly? This changes In this step by step blog, you will learn to set up and configure ingress for Istio mesh using Kubernetes Gateway API with examples. Documentation for Istio Service Mesh Workshop Traffic encryption using mTLS Introduction Transport authentication, also known as service-to-service authentication ensures that traffic is encrypted on transit between services.

In “chained” mode, we use both the third party ingress and Istio’s own Gateway in sequence. The service mesh (like Istio or Linkerd) manages "east-west" traffic, providing service discovery, load balancing, and mutual TLS (mTLS) encryption for secure inter-service communication. 4 TLS终结策略下沉与mTLS双向认证链路贯通：从Istio Citadel到Go网关证书管理实践当服务网格控制面从Istio Citadel迁移至轻量级Go网关时，TLS终结点需从Sidecar下沉至边缘入口层，同时维持端到端mTLS信任链。 The API Gateway (like AWS API Gateway or Kong) is responsible for "north-south" traffic, managing tasks like authentication, rate limiting, and request routing. Using auto-injection for gateway deployments is recommended as it gives developers full control over the gateway deployment, while also simplifying operations. Blog for OneUptime . Application Gateway does not have support for backend TLS encryption (often called re-encrypt). Authorization policy supports CUSTOM, DENY and ALLOW actions for access control. The Istio ingress gateway supports mTLS authentication for external clients. However, the ingress will not use mTLS, which may lead to undesirable behavior. When CUSTOM, DENY and ALLOW actions are used for a workload at the same time, the CUSTOM action is evaluated first, then the DENY action, and finally the ALLOW action. How it works Mutual TLS can be enabled on 3 levels: Service: Enable mTLS for a subset of services. This process has set up mTLS and verified traffic from the egress gateway to the ingress gateway. In sidecar mode, PeerAuthentication determines whether or not mTLS is allowed or required for connections to an Envoy proxy sidecar. Learn how to install and configure MetalLB and Istio Ingress Gateway with Mutual TLS on Kubernetes to secure and manage external traffic. yaml └── linkerd/ ├── api-trafficsplit. One or more labels are typically required to identify the subset destination, however, when the corresponding DestinationRule represents a host that supports multiple SNI hosts (e. In the above condition in the application gateway definition you can declare mode: simple and attach an secret. When a new upgrade is available, or a In order to achieve mTLS , the ingress gateway and the backend application must both present and verify certificates. Follow instructions under either the Gateway API or Istio APIs tab, according to your preference. While Istio will configure the proxy to listen on these ports, it is the responsibility of the user to ensure that external traffic to these ports are allowed into the mesh. Istio supports the Kubernetes Gateway API and intends to make it the default API for traffic management in the future. This configuration guarantees secure communication between your services and efficiently manages TLS certificates. As observability becomes increasingly critical in modern distributed systems, centralizing telemetry data via OTel Collectors deployed in one or many Documentation for Istio Service Mesh Workshop Traffic encryption using mTLS Introduction Transport authentication, also known as service-to-service authentication ensures that traffic is encrypted on transit between services. Enable the Istio add-on in AKS. Learn the architecture of mTLS authentication and know how certificate, public and private key work. The istio-ingress-gateway and istio-egress-gateway are just two specialized gateway deployments. The gateway will be applied to the proxy running on a pod with labels app: my-gateway-controller. The following instructions allow you to choose to use either the Gateway API or the Istio configuration API when configuring traffic management in the mesh. This article shows how to expose a secure HTTPS service using either simple or mutual TLS. This can be useful when you want the functionality of both layers. No special changes are needed to work with Istio. Configuring the installation Updating the config-istio configmap to use a non-default local gateway If you create a custom service and deployment for local gateway with a name other than knative-local-gateway, you need to update gateway configmap config-istio under the knative-serving namespace. yml in a namespace with side-car auto injection enabled Output Structure generated-configs/ ├── istio/ │ ├── api-gateway. It can be a service on the edge that communicate with the external Where <filename> is the name of the file you created in the previous step. It extends AKO ’s existing Istio integration to support Gateway API (HTTPRoute resources) in both ClusterIP and NodePort modes. When configuring this setup, the Kubernetes secret referenced in the Istio Gateway must include a ca. Capture some more packets to prove that traffic between the application and the database is encrypted. Istio can come in and do the job but using out-of-the-box ISTIO_MUTUAL mode (between istio-proxy and egress gateway) is not the case for us. Restart istio gateway container & Wait……. client services make mTLS connection with target services using appropriate certificates. yaml │ ├── api-virtualservice. 金融行业对数据完整性、服务可用性与访问可审计性的严苛要求，正持续推动微服务架构向更细粒度、更高安全基线的方向演进。传统基于边界防护的网络模型在容器化、多云及混合部署场景下迅速失效，而零信任服务网格（Zero Trust Service Mesh）凭借其“默认拒绝、持续验证、最小权限”的核心原则 Incoming TLS traffic is terminated at the Istio ingress gateway level and then sent to the destination service encrypted via mTLS within the service mesh. Dive into securing application communications, mTLS and Istio to achieve end-to-end mTLS among your applications. Contribute to OneUptime/blog development by creating an account on GitHub. yaml └── api-httproute. Configure Istio service mesh to handle mutual TLS (mTLS) with external sites using egress gateways. So, I've tried using example Configure mutual TLS origination for egress traffic by modifying it a bit as follows (changes marked with #- and #+): TLS origination occurs when an Istio proxy (sidecar or egress gateway) is configured to accept unencrypted internal HTTP connections, encrypt the requests, and then forward them to HTTPS servers that are secured using simple or mutual TLS. Understand how to verify mTLS is enabled among workloads in an ambient mesh. Turn Istio and Envoy from “it should work” into behavior you can prove at the proxy. svc. , an egress gateway), a subset without labels may be meaningful. Learn how to implement mTLS using Istio service mesh. Objectives In this workshop, you will learn how to use the Istio service mesh with Azure Kubernetes Service (AKS). yaml │ └── default-mtls. This article introduces TLS and mTLS, and describes how to enable mTLS in Istio and its application scenarios. It provides the framework for: Issuing unique client certificates to every service or user that needs to authenticate. . Istio Authorization Policy enables access control on workloads in the mesh.
