Kuberneted配置 - 容器没有部署的资源请求

Question

我在Gitlab中的Kubernetes配置挣扎。

我正在研究某人像一年前一样配置的项目，项目具有后端和前端部分，我想在应用程序配置中更新密码。不幸的是，在使用GitLab配置部署后，以前的开发人员离开了，似乎没有部署新版本的代码，并且应用程序仍在使用旧密码。试图在代码中进行一些其他更改，例如通过Liquibase添加新表，并且此问题仍然发生，部署后没有创建表。

运输应用程序中的所有对象，它用于后端部分，POD，Service，deployment.Apps for Backend。

secret/regcred-dashboard unchanged
service/IE599-dashboard created
ingress.extensions/IE599-dashboard configured
Error from server ([denied by k8sresourcesrequestandatory] container <IE599-dashboard> has no resource requests for deployment <IE599-dashboard>): error when creating "STDIN": admission webhook "validation.gatekeeper.sh" denied the request: [denied by k8sresourcesrequestandatory] container <IE599-dashboard> has no resource requests for deployment <IE599-dashboard>

我决定删除DEV名称空间和重新 对Kubernetes没有任何经验，我现在不知道怎么了。

使用以下gitlab配置

deploy to dev:
  extends:
    - .deployment
    - .dev
  stage: dev
  before_script:
    - export CI_ENV=dev
  when: manual

.deployment:
  dependencies:
    - containerize
  extends:
    - .k8s
  script:
    - envsubst < ./kubernetes/${CI_ENV}/deployment.yaml | kubectl apply -n IE599-${CI_ENV} -f -

不确定为什么它不起作用，我会在这里感谢任何帮助。

Answer 1

在部署中，您将

          resources:
            limits:
              cpu: '100m'
              memory: 256Mi

其更新为：

          resources:
            limits:
              cpu: '100m'
              memory: 256Mi
            requests:
              cpu: '50m'
              memory: 200Mi

您遇到的错误（没有部署的资源请求＆lt; ie599-dashboard＆gt;）是K8的告诉您，您在部署中没有资源请求。
