How to customize hostAliases for gitlab toolbox backups?
- 本人创建的议题
- 项目 极狐GitLab Chart 开发者 Jason Plum 已确认， 后期将增加基于 helm 的
hostAliases配置
查看现有备份
kubectl -n gitlab-test get cronjobs.batch
# 默认没有开启
[root@k8s ~]# kubectl -n gitlab-test get cronjobs.batch
No resources found in gitlab-test namespace.
[root@k8s ~]#
开启自动备份功能
# 将已配置的值导出到文件中
helm -n gitlab-test get values my-gitlab > my-gitlab.yaml# 开启备份功能
# gitlab.toolbox.backups.cron.enabled：是否开启备份功能
# gitlab.toolbox.backups.cron.schedule：备份的计划，每天的 1:00（UTC） 备份
# -f gitlab-helm.yaml：指定已配置的值
helm upgrade -n gitlab-test --install my-gitlab gitlab/gitlab \--set gitlab.toolbox.backups.cron.enabled=true \--set gitlab.toolbox.backups.cron.schedule="0 1 * * *" \-f my-gitlab.yaml \--timeout 600s \--version 7.7.0
# 等待时间到了，就能自动备份了
[root@k8s ~]# kubectl -n gitlab-test get cronjobs.batch
NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE
my-gitlab-toolbox-backup 0 1 * * * False 0 <none> 11s
[root@k8s ~]#
创建手动备份
# -n gitlab-test：指定命名空间
# --from=cronjob/my-gitlab-toolbox-backup：指定 cronjob 名称，其中 gitlab-test 是安装时设置 gitlab 的名称
# manual-backup-1：手动备份名称，名称不可以重复
kubectl -n gitlab-test create job --from=cronjob/my-gitlab-toolbox-backup manual-backup-1
查看备份
kubectl -n gitlab-test get jobs.batch
搜索手动备份的job的pod
kubectl -n gitlab-test get pod | grep manual-backup-1
# Running：代表正在运行
# Completed：代表执行完成
[root@k8s ~]# kubectl -n gitlab-test get pod | grep manual-backup-1
manual-backup-1-r7qlj 1/1 Running 0 15s
[root@k8s ~]#
查看手动备份的job的pod日志
kubectl -n gitlab-test logs -f manual-backup-1-r7qlj

修改 定时任务
kubectl -n gitlab-test edit cronjobs.batch my-gitlab-toolbox-backup
增加 域名解析
# 增加自定义域名解析，放在 dnsPolicy 后面hostAliases:- hostnames:- minio.test.helm.xuxiaowei.cnip: 172.25.25.32
- 删除手动备份 job（若已完成备份，则备份数据已上传至 minio 存储，此处不会删除备份数据），重新创建手动备份 job，即可使用自定义域名解析了
kubectl -n gitlab-test delete job manual-backup-1
证书验证异常
- gitlab 备份到 MinIO 时证书验证失败解决方案：gitlab 备份 信任域名证书
