k8s 1.28.2 集群部署 docker registry 接入 MinIO 存储
docker registry 部署
生成 htpasswd 文件
<username> <password>改成自己想配置的，如果密码有特殊字符，要用单引号包起来
docker run --rm \
docker.m.daocloud.io/httpd:latest \
htpasswd -Bbn <username> <password> > htpasswd
生成 secret 文件
kubectl create secret generic docker-registry-auth \
-n registry \
--from-file=htpasswd
生成 registry 配置文件
因为涉及到 MinIO 的
accesskey和secretkey，这里采用 secret 的方式来生成配置文件

创建 ingress
没有 ingress 可以开 nodeport 来实现

验证 docker registry
/etc/docker/daemon.json 增加 registry 地址
"insecure-registries": ["ip:端口"]
# 或者
"insecure-registries": ["域名"]
登录 docker registry
docker login http://registry.devops.icu
修改 tag
docker tag docker.m.daocloud.io/registry:2.8.3 registry.devops.icu/registry:2.8.3
上传镜像
docker push registry.devops.icu/registry:2.8.3
