Taint eks node-group

由 独自空忆成欢 提交于 2021-02-18 17:51:40
问题 I have a cluster with 2 node groups: real time and general . I would like only pods which tolerate affinity real time to be able to run on nodes from the real time cluster. My approach was to taint the relevant nodes and add toleration to the pod that I want to register to that node. I came into a dead-end when I was trying to taint a node-group. In my case I have an EKS node group that is elastic, i.e. nodes are increasing and decreasing in numbers constantly. How can I configure the group

Helm 安装 nginx-ingress 的方法

由 陌路散爱 提交于 2021-02-18 17:02:33
还是没学会 今天继续研究. Using Helm NGINX Ingress controller can be installed via Helm using the chart stable/nginx from the official charts repository. To install the chart with the release name my-nginx : helm install stable/nginx-ingress --name my-nginx If the kubernetes cluster has RBAC enabled, then run: helm install stable/nginx-ingress --name my-nginx -- set rbac.create= true 好像不管用呢... 试过了 不太行 貌似. 来源： oschina 链接： https://my.oschina.net/u/4316097/blog/3863962

Docker build inside kubernetes pod fails with “could not find bridge docker0”

由 筅森魡賤 提交于 2021-02-18 13:53:43
问题 I moved our build agents into Kubernetes / Container Engine. They used to run on container vm (version container-vm-v20160321) and mount docker.sock into the docker container so we can run docker build from inside the container. This used the following manifest: apiVersion: v1 kind: Pod metadata: name: gocd-agent spec: containers: - name: gocd-agent image: travix/gocd-agent:16.8.0 imagePullPolicy: Always volumeMounts: - name: ssh-keys mountPath: /var/go/.ssh readOnly: true - name: gcloud-keys

Is it possible to rewrite HOST header in k8s Ingress Controller?

由 我只是一个虾纸丫 提交于 2021-02-18 10:20:41
问题 Due to some legacy application that relies on Host header to function correctly, I need to have an Ingress (proxy, etc) that capable of rewrite Host header and pass that to downstream (backend). Is there any Ingress Controller that supports this functionality? Example: End user access our website through foo.com/a for backend a and foo.com/b for backend b . But since a and b are legacy app, it only accept: a accepts connection when Host: a.foo.com b accepts connection when Host: b.foo.com 回答1
