We have recently introduced the Istio service mesh in our Kubernetes clusters to take advantage of its traffic management, security and observability features. One of our key requirements is to enforce TLS/encryption on traffic in transit across all layers. Within the cluster, this is done via mTLS provided by Istio. For external traffic as well as traffic at the service mesh edge, we use the…

curl เป็น command นึงที่ใช้บ่อยมากทั้ง download ไฟล์ รวมถึง verify และ debug การทำงานของ web application หลายวันก่อนมี app มาขึ้นใน Kubernetes cluster ก็มีการคุยถึงวิธีที่จะ expose service ออกไปนอก cluster ซึ่งถ้าเป็น HTTP/HTTPS ก็แนะนำให้ใช้ Ingress นี่ล่ะง่ายดี ถ้ายังไม่ได้จด domain ก็บอกวิธี test ไปว่าลองใช้ curl ตามนี้ สมมติ app เรามีชื่อ domain คือ my.domain.com ถ้าอยากจะทดสอบแบบเร็วๆว่า Ingress ทำงานได้ก็สามารถใช้คำสั่ง curl โดยระบุ flag -H ตามด้วย string Host: แล้วก็ชี้ไปที่ IP ของ endpoint เช่น VIP ของ Load balance หรือ Worker node IP วันนี้ทีม…

But what if you need to generate an SSL/TLS certificate using HTTP01 solver alongside a DNS01 solver? Solution: We can configure the ClusterIssuer to support both DNS01 and HTTP01 Solvers. In this article, we will look at how we can handle both HTTP01 and DNS01 solvers…

For example, we required tracking configuration changes, Kubernetes-native interface for API endpoints definitions, and development of extensions or plugins. In this blog post, I will discuss what our ingress looked like before Ambassador, the problems we uncovered and…
