【云原生】Kubernetes部署Kanboard项目管理平台

文章目录

介绍

  • Kanboard是一个简介而强大的任务看板管理系统，它以敏捷开发理念为基础，皆在帮助个人和团队提高工作效率、优化工作流程。通过其直观的界面和灵活的配置选项，用户可以轻松地进行项目管理、任务分配、并跟踪进度

资源列表

操作系统 配置 主机名 IP k8s版本
CentOS 7.9 2C4G k8s-master 192.168.93.101 v1.18.0
CentOS 7.9 2C4G k8s-node01 192.168.93.102 v1.18.0
CentOS 7.9 2C4G k8s-node02 192.168.93.103 v1.18.0

基础环境

  • 关闭防火墙
bash 复制代码 
systemctl stop firewalld
systemctl disable firewalld

  • 关闭内核安全机制

    setenforce 0
    sed -i "s/^SELINUX=.*/SELINUX=disabled/g" /etc/selinux/config

一、检查k8s环境

  • 提前部署一个k8s集群，采用kubeadm或二进制安装都可以

1.1、检查工作节点状态

[root@k8s-master ~]# kubectl get node
NAME         STATUS   ROLES    AGE    VERSION
k8s-master   Ready    master   158m   v1.18.0
k8s-node01   Ready    <none>   157m   v1.18.0
k8s-node02   Ready    <none>   157m   v1.18.0

1.2、检查系统pod状态

  • 检查k8s集群中各系统组件的pod状态，确保都处于正常状态

    [root@k8s-master ~]# kubectl get pod -n kube-system
    NAME READY STATUS RESTARTS AGE
    calico-kube-controllers-858fbfbc9-l8tpp 1/1 Running 1 157m
    calico-node-k6qbl 1/1 Running 1 157m
    calico-node-q969p 1/1 Running 1 157m
    calico-node-sv48g 1/1 Running 1 157m
    coredns-7ff77c879f-lnl72 1/1 Running 1 158m
    coredns-7ff77c879f-nfx7g 1/1 Running 1 158m
    etcd-k8s-master 1/1 Running 1 159m
    kube-apiserver-k8s-master 1/1 Running 1 159m
    kube-controller-manager-k8s-master 1/1 Running 1 159m
    kube-proxy-2c282 1/1 Running 1 158m
    kube-proxy-6n6pn 1/1 Running 1 158m
    kube-proxy-zhm2m 1/1 Running 1 158m
    kube-scheduler-k8s-master 1/1 Running 1 159m

二、编辑kanboard.yaml文件

  • yaml文件直接复制粘贴即可

2.1、创建项目目录

[root@k8s-master ~]# mkdir -p /data/kanboard
[root@k8s-master ~]# cd /data/kanboard/

2.2、编辑kanboard.yaml文件

  • 执行以下命令之前可以选择先导入需要的镜像，手动进行拉取，不然如果镜像拉去不下来的话，pod就会运行不起来，镜像拉取不下来的可以私信或者评论（开源）

    [root@k8s-master kanboard]# vim kanboard.yaml

    apiVersion: v1
    kind: Namespace
    metadata:
    name: kanboard

    apiVersion: apps/v1
    kind: Deployment
    metadata:
    labels:
    app: kanboard
    name: kanboard
    namespace: kanboard
    spec:
    replicas: 2
    selector:
    matchLabels:
    app: kanboard
    template:

    initContainers:

    - name: volume-permissions

    image: busybox:1.28

    imagePullPolicy: IfNotPresent

    command:

    - sh

    - -c

    - chmod 777 /data/kanboard/data/

    volumeMounts:

    - name: web

    mountPath: /data/kanboard/data/

        containers: 
    - image:   kanboard/kanboard:v1.2.26
      name: my-kanboard
      ports:
      - name:  web 
        protocol: "TCP"
        containerPort: 80
      - name:  ssl
        protocol: "TCP"
        containerPort: 443


      env:
      - name: TZ
        value: "Asia/Shanghai"
     


      resources:         
       requests:
           cpu: 0.1
           memory: 0.1G
       limits:
           cpu: 1
           memory:  0.5G
      volumeMounts:
      - name: data
        mountPath: /var/www/html
      - name: plugins
        mountPath: var/www/app/plugins
      - name: ssl
        mountPath: /etc/nginx/ssl

    apiVersion: v1
    kind: Service
    metadata:
    name: my-kanboard
    namespace: kanboard
    spec:
    ports:
    - name: web

    targetPort: 80
    port: 80
    nodePort: 30080
    - name: ssl
    protocol: TCP
    targetPort: 443
    port: 443
    nodePort: 30090

    selector:
    app: kanboard
type: NodePort

三、部署Kanboard

3.1、部署Kanboard服务

  • 应用kanboard.yaml文件

    [root@k8s-master kanboard]# kubectl apply -f kanboard.yaml
    namespace/kanboard created
    deployment.apps/kanboard created
    service/my-kanboard created

3.2、检查pod状态

# 查看pod的详细信息
[root@k8s-master kanboard]# kubectl get pod -n kanboard -owide
NAME                        READY   STATUS    RESTARTS   AGE   IP              NODE         NOMINATED NODE   READINESS GATES
kanboard-7f447d6bd6-446rz   1/1     Running   0          32s   10.244.85.195   k8s-node01   <none>           <none>
kanboard-7f447d6bd6-xtmbl   1/1     Running   0          32s   10.244.58.195   k8s-node02   <none>           <none>

3.3、检查pod详细信息

  • 查看kanboard的pod详细信息

    [root@k8s-master kanboard]# kubectl describe pod -n kanboard kanboard-7f447d6bd6-446rz
    Name: kanboard-7f447d6bd6-446rz

    Ready: True
    Restart Count: 0
    Limits:
    cpu: 1
    memory: 500M
    Requests:
    cpu: 100m
    memory: 100M
    Environment:
    TZ: Asia/Shanghai
    Mounts:
    /etc/nginx/ssl from ssl (rw)
    /var/run/secrets/kubernetes.io/serviceaccount from default-token-7k9kj (ro)
    /var/www/html from data (rw)
    var/www/app/plugins from plugins (rw)
    Conditions:
    Type Status

    Volumes:
    data:
    Type: HostPath (bare host directory volume)
    Path: /data/kanboard/data/
    HostPathType:
    plugins:
    Type: HostPath (bare host directory volume)
    Path: /data/kanboard/plugins/
    HostPathType:
    ssl:
    Type: HostPath (bare host directory volume)

    Type Reason Age From Message
    ---- ------ ---- ---- -------
    Normal Scheduled 79s default-scheduler Successfully assigned kanboard/kanboard-7f447d6bd6-446rz to k8s-node01
    Normal Pulled 78s kubelet, k8s-node01 Container image "kanboard/kanboard:v1.2.26" already present on machine
    Normal Created 78s kubelet, k8s-node01 Created container my-kanboard
    Normal Started 78s kubelet, k8s-node01 Started container my-kanboard

3.4、查看service状态

  • 检查service状态。kanboard的外部访问端口为30080和30090

    servcie简称svc

    [root@k8s-master kanboard]# kubectl get svc -n kanboard
    NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
    my-kanboard NodePort 10.109.78.136 <none> 80:30080/TCP,443:30090/TCP 2m59s
