docker - Kubernetes部署数据库连接错误

问题描述

我正在尝试在我的 Kubernetes 集群上部署 GLPI 应用程序（http://glpi-project.org/），但我遇到了一个问题。

这是我的部署代码：

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pv-claim-glpi
  labels:
    type: openebs
spec:
  storageClassName: openebs-storageclass
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
---

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: glpi
  namespace: jb
  labels:
    app: glpi
spec:
  selector:
    matchLabels:
      app: glpi
  replicas: 1 # tells deployment to run 1 pods matching the template
  template: # create pods using pod definition in this template
    metadata:
      # unlike pod-nginx.yaml, the name is not included in the meta data as a unique name is
      # generated from the deployment name
      labels:
        app: glpi
    spec:
      volumes:
      - name: pv-storage-glpi
        persistentVolumeClaim:
          claimName: pv-claim-glpi
      containers:
      - name: mariadb
        image: mariadb
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: "glpi"
        - name: MYSQL_DATABASE
          value: "glpi"
        - name: MYSQL_USER
          value: "glpi"
        - name: MYSQL_PASSWORD
          value: "glpi"
        - name: GLPI_SOURCE_URL
          value: "https://forge.glpi-project.org/attachments/download/2020/glpi-0.85.4.tar.gz"
        ports:
        - containerPort: 3306
          name: mariadb
        volumeMounts:
        - mountPath: /var/lib/mariadb/
          name: pv-storage-glpi
          subPath: mariadb

        volumeMounts:
        - mountPath: /var/glpidata
          name: pv-storage-glpi
          subPath: glpidata

docker 映像已正确部署，但在我的测试阶段，在应用程序设置期间，我在设置数据库（mysql）时收到以下错误。

错误glpi

我已经检查了凭据（主机、用户名、密码）并且是正确的

请帮忙

解决方案

不是一个真正的答案，因为我没有预期的 Kubernetes 知识，但我还不能添加评论:(

你应该首先改变的是你的 GLPi 版本。使用此链接。这是最后一个： https ://github.com/glpi-project/glpi/releases/download/9.3.0/glpi-9.3.tgz

然后您可以使用 cli 工具来设置数据库。 https://glpi-install.readthedocs.io/en/latest/command-line.html

使用我从您的文件中获得的信息：

php scripts/cliinstall.php --host=mariadb(not sure about this one in your environment but you get hte idea) --db=glpi --user=glpi --pass=glpi
