在k8s集群基于nfs共享存储部署jenkins单体服务

一、准备jenkins镜像

docker pull jenkins/jenkins:2.374docker tag jenkins/jenkins:2.374 harbor.magedu.net/magedu/jenkins:2.374docker push harbor.magedu.net/magedu/jenkins:2.374

二、在nfs共享存储暴露nfs共享目录

[root@easzlab-k8s-nfs-01 ~]# cat /etc/exports 
# /etc/exports: the access control list for filesystems which may be exported
#        to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
/data 172.16.88.0/24(rw,sync,no_root_squash,no_subtree_check)
/data/k8sdata/magedu/jenkins-root-data 172.16.88.0/24(rw,sync,no_root_squash,no_subtree_check)
/data/k8sdata/magedu/jenkins-data 172.16.88.0/24(rw,sync,no_root_squash,no_subtree_check)
[root@easzlab-k8s-nfs-01 ~]#
[root@easzlab-k8s-nfs-01 ~]# exportfs -r
root@easzlab-deploy:~# showmount -e 172.16.88.169
Export list for 172.16.88.169:
/data/k8sdata/magedu/jenkins-data      172.16.88.0/24
/data/k8sdata/magedu/jenkins-root-data 172.16.88.0/24
/data                                  172.16.88.0/24
root@easzlab-deploy:~# 

三、准备jenkins相关部署配置文件

root@easzlab-deploy:~/jiege-k8s/20220807/k8s-data-n70-20220807/yaml/magedu/jenkins/pv# cat jenkins-persistentvolumeclaim.yaml
