一简介

Nexus 是Maven仓库管理器，如果你使用Maven，你可以从Maven中央仓库下载所需要的构件（artifact），但这通常不是一个好的做法，你应该在本地架设一个Maven仓库服务器，在代理远程仓库的同时维护本地仓库，以节省带宽和时间，Nexus就可以满足这样的需要。此外，他还提供了强大的仓库管理功能，构件搜索功能，它基于REST，友好的UI是一个extjs的REST客户端，它占用较少的内存，基于简单文件系统而非数据库。这些优点使其日趋成为最流行的Maven仓库管理器

二安装配置

2.1 环境准备

需要有默认存储我这边使用的是sc

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: nexus-data-pvc
  namespace: nexus
  annotations:
    kubesphere.io/creator: admin
    pv.kubernetes.io/bind-completed: 'yes'
    pv.kubernetes.io/bound-by-controller: 'yes'
    volume.beta.kubernetes.io/storage-provisioner: nfs-provisioner-k8s
  finalizers:
    - kubernetes.io/pvc-protection
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  volumeName: pvc-8ac315a8-fdac-460d-9c95-41d0a7bc7e7e
  storageClassName: nfs-k8s
  volumeMode: Filesystem

2.2 配置deploy

            - '-c'
            - 'chown -R ${USER_ID}:${USER_ID} ${DATA_DIR}'
          env:
            - name: DATA_DIR
              value: /nexus-data
            - name: USER_ID
              value: '200'
          resources: {}
          volumeMounts:
            - name: nexus-data
              mountPath: /nexus-data
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: Always
