问题 I am new to Openshift. I have deployed an application in openshift. When I checked the logs, there is permission denied error for some files. Now, I want to change the permissions on the the container that is already deployed in Openshift, but I am getting, "Operation not permitted" warning. How do I fix this ? This is for linux running latest version of MongoDB. I have already tried executing RUN chmod 777 /path/to/directory in my docker file, created the image and pulled the same image in

后来居上的KubeSphere ，欲在云原生时代构建Native生态

作者 | 中国软件网 陈杨 校对 | 中国软件网 海策 无论是数字化转型浪潮下，企业对应用、服务的快速迭代、交付需求，还是容器、微服务、DevOps、分布式应用架构等技术的发展成熟，迈向云原生已成必然。企业对混合云的超高接纳度更使得容器化应用成为追捧的对象。 Gartner 2019 年发布的一份报告预计：2020 年，有 50% 的传统老旧应用被以云原生化的方式改造。2022 年时，将有 75% 的全球化企业将在生产中使用云原生的容器化应用。 即便Kubernetes早已成为容器编排的公认标准，但其高门槛仍然阻碍了不少企业走上云原生之路。不得不承认，OpenShift、Rancher等容器平台的出现帮助企业降低了这一门槛。这一观点也得到了青云QingCloud应用及容器平台研发总监周小四的认可。 不过，周小四也提出了自己的看法：OpenShift、Rancher在容器管理上确实做的不错，但不够完美。 这也是周小四不断迭代、完善KubeSphere的驱动力：为企业、用户提供更简单、更完善的容器平台，完成云原生应用的一步跨入。 青云QingCloud应用及容器平台研发总监周小四 01 从追赶到超越，KubeSphere三年磨一剑 “我认为，KubeSphere在国内没有太多的竞争对手，已经在国内站稳了脚跟。”谈到KubeSphere的表现，周小四充满了自信。“在国外

问题 I want to know if there is anyway to define the kubernate or openshift template to load environment variables from a file in one of the volumes. What i'm trying to achieve is to: generate a value on a initContainer write value on a file load value as an environment variable when starting the main container If anyone knows an alternative to allow the main container to read a environment variable generated from the initContainer it will solve my problem too Thank you 回答1: I can see 2 ways to

OpenShift是一个基于容器技术的云平台，这里的容器技术指的就是docker和kubernetes. Openshift 错误解决 错误信息 failed to run Kubelet: failed to create kubelet: misconfiguration: kubelet cgroup driver: "systemd" is different from docker cgroup driver: "cgroupfs" 解决 vi /usr/lib/systemd/system/docker.service 改为 #ExecStart=/usr/bin/dockerd ExecStart=/usr/bin/dockerd --exec-opt native.cgroupdriver=systemd 重启docker systemctl daemon-reload systemctl restart docker 参考：https://blog.csdn.net/engchina/article/details/78823347 根据官方文档，selinux要修改为： SELINUX= enforcing SELINUXTYPE= targeted cd /opt/ tar -zxf openshift-origin-server-v3.7.0-7ed6862

Horizontal pod Autoscaling without custom metrics

由 有些话、适合烂在心里 提交于 2020-12-13 03:30:57
问题 We want to scale our pods horizontally based on the amount of messages in our Kafka Topic. The standard solution is to publish the metrics to the custom metrics API of Kubernetes. However, due to company guidelines we are not allowed to use the custom metrics API of Kubernetes. We are only allowed to use non-admin functionality. Is there a solution for this with kubernetes-nativ features or do we need to implement a customized solution? 回答1: I'm not exactly sure if this would fit your needs

被弃用的 Docker 会被 Podman 取代吗？

Kubernetes 团队近日宣布将在最新版本中弃用 Docker 支持的功能，后续版本会陆续删除这些功能。 编译 | 弯月 责编 | 张文，郑丽媛 头图 | CSDN 下载自视觉中国 出品 | CSDN（ID：CSDNnews） 近日，Kubernetes 团队发布了最新的 1.20 版本，新版本更新了许多内容： 存储卷快照功能趋于稳定；Kubectl Debug 进入 Beta；Beta：API 优先级和公平性；IPV4/IPV6 Alpha 功能更新；GA：限制进程 PID；Dockershim 弃用；Exec 探针超时处理等等（详情可查看： https://kubernetes.io/blog/2020/12/08/kubernetes-1-20-release-announcement/ ） 其 中，有一项更新对于开发者社区来说无疑是一枚重磅炸弹： 正式宣布弃用 Docker 支持的功能。 那么，究竟 Kubernetes 为什么要这么做，以及这么做会有什么影响呢？ Docker 是一种以容器化的方式打包、分发和部署应用程序的方式。自 2013 年 3 月 13 日初始版本发布以来，Docker 已成为容器业界的事实标准。而Kubernetes 是一款由 Google 开发的开源容器编排系统。 Kubernetes 架构示意图，来自维基百科 Docker 与
