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 statefulset

创建 ingress

没有 ingress 可以开 nodeport 来实现

---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: 5G
  name: docker-registry
  namespace: registry
spec:
  ingressClassName: nginx
  rules:
  - host: registry.devops.icu
    http:
      paths:
      - backend:
          service:
            name: docker-registry-svc
            port:
              number: 5000
        path: /
        pathType: Prefix

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

docker registry 监控

grafana id：9621

在这里插入图片描述

prometheus 配置文件参考

    - job_name: docker-registry
      kubernetes_sd_configs:
      - role: endpoints
      relabel_configs:
      - source_labels: [__meta_kubernetes_namespace, __meta_kubernetes_service_name]
        regex: registry;docker-registry-svc
        action: keep
      - source_labels: [__meta_kubernetes_pod_ip]
        regex: (.+)
        target_label: __address__
        replacement: ${1}:5001
      - source_labels: [__meta_kubernetes_endpoints_name]
        action: replace
        target_label: endpoint
      - source_labels: [__meta_kubernetes_pod_name]
        action: replace
        target_label: pod
      - source_labels: [__meta_kubernetes_service_name]
        action: replace
        target_label: service
      - source_labels: [__meta_kubernetes_namespace]
        action: replace
        target_label: namespace
