GitLab 是一个全球知名的一体化 DevOps 平台，很多人都通过私有化部署 GitLab 来进行源代码托管。极狐GitLab 是 GitLab 在中国的发行版，专门为中国程序员服务。可以一键式部署极狐GitLab。
本文主要讲述了如何在[极狐GitLab]使用Docker 仓库功能。
说明
- 示例项目：https://framagit.org/xuxiaowei-com-cn/docker

执行流水线异常，无法解析域名地址
导出 helm gitlab 配置
# 将已配置的值导出到文件中
helm -n gitlab-test get values my-gitlab > my-gitlab.yaml
查看 极狐GitLab runner 默认配置
# 此处为节选，不同版本可能会存在差异，请以 https://artifacthub.io/packages/helm/gitlab/gitlab?modal=values 中的配置为准
gitlab-runner:runners:config: |[[runners]][runners.kubernetes]image = "ubuntu:22.04"{{- if .Values.global.minio.enabled }}[runners.cache]Type = "s3"Path = "gitlab-runner"Shared = true[runners.cache.s3]ServerAddress = {{ include "gitlab-runner.cache-tpl.s3ServerAddress" . }}BucketName = "runner-cache"BucketLocation = "us-east-1"Insecure = false{{ end }}
修改配置如下
gitlab-runner:
runners:config: |[[runners]][runners.kubernetes]image = "ubuntu:22.04"[[runners.kubernetes.host_aliases]]ip = "172.25.25.32"hostnames = [ "registry.test.helm.xuxiaowei.cn" ]{{- if .Values.global.minio.enabled }}[runners.cache]Type = "s3"Path = "gitlab-runner"Shared = true[runners.cache.s3]ServerAddress = {{ include "gitlab-runner.cache-tpl.s3ServerAddress" . }}BucketName = "runner-cache"BucketLocation = "us-east-1"Insecure = false{{ end }}
更新配置
helm upgrade -n gitlab-test --install my-gitlab gitlab/gitlab --timeout 600s -f my-gitlab.yaml --version 7.7.0
等待所有旧 pod 删除完成，新 pod 正常运行时，重试流水线，即可正确解析到 registry（Docker 仓库）的 IP
域名证书验证失败
下载证书
# 下载证书
openssl s_client -showcerts -connect registry.test.helm.xuxiaowei.cn:443 -servername registry.test.helm.xuxiaowei.cn < /dev/null 2>/dev/null | openssl x509 -outform PEM > registry.test.helm.xuxiaowei.cn.crt
openssl s_client -showcerts -connect gitlab.test.helm.xuxiaowei.cn:443 -servername gitlab.test.helm.xuxiaowei.cn < /dev/null 2>/dev/null | openssl x509 -outform PEM > gitlab.test.helm.xuxiaowei.cn.crt
将证书导入到 k8s 中
# -n=gitlab-test：指定命名空间
# create configmap registry-certs：创建 ConfigMap 名称是 registry-certs
# --from-file=registry.test.helm.xuxiaowei.cn.crt=registry.test.helm.xuxiaowei.cn.crt：配置来自文件，文件名 registry.test.helm.xuxiaowei.cn.crt，放入 ConfigMap 中的键也是 registry.test.helm.xuxiaowei.cn.crt
kubectl -n=gitlab-test create configmap registry-certs --from-file=registry.test.helm.xuxiaowei.cn.crt=registry.test.helm.xuxiaowei.cn.crt
kubectl -n=gitlab-test create configmap gitlab-certs --from-file=gitlab.test.helm.xuxiaowei.cn.crt=gitlab.test.helm.xuxiaowei.cn.crt# 查看
# kubectl -n=gitlab-test get configmap registry-certs -o yaml
# kubectl -n=gitlab-test get configmap gitlab-certs -o yaml
导出 helm 极狐GitLab 配置
helm -n gitlab-test get values my-gitlab > my-gitlab.yaml
