背景:
要装置一系列的工具,如:jenkins spinnaker gitlab。账号零碎是一件烦人的事件。前两年本人也试过 openladap 这样的对立账号治理认证。当初就想再用一下. 把几个软件的账户零碎整合一下(次要是想上 spinnaker 了)。搭建形式根本参照:https://mutoulazy.github.io/2021/04/01/kubernetes/openLDAP/#%E5%9C%A8k8s%E4%B8%AD%E9%83%A8%E7%BD%B2。不过这个哥们写的配置文件也比拟乱,起码的 pv,pvc 应该先创立吧?yaml 程序整的杂七乱八的都是创立了服务后导出的 …..,另外还有这里两个的能够参考:Kubernetes – – k8s – v1.12.3 OpenLDAP 对立认证 kubernetes 实战 (十一):k8s 应用 openLDAP 对立认证
反正就联合这几个搞一下吧!
kubernetes 搭建 openLDAP
1. 创立 pvc
默认存储 cbs,间接应用了腾讯云的 cbs 块存储(最小 10G 的步长也是 10G)
cat <<EOF > pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: ldap-data-pvc
namespace: kube-ops
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
storageClassName: cbs
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: ldap-config-pvc
namespace: kube-ops
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
storageClassName: cbs
EOF
kubectl apply -f pvc.yaml
2. 创立 ldap deployment svc 服务
cat <<EOF > ldap-deployment.yaml
kind: Deployment
apiVersion: apps/v1
metadata:
name: openldap
namespace: kube-ops
labels:
app: openldap
annotations:
app.kubernetes.io/alias-name: LDAP
app.kubernetes.io/description: 认证核心
spec:

persistentVolumeClaim:

selector:
app: openldap
EOF
kubectl apply -f ldap-deployment.yaml
kubectl logs -f openldap-6d9859cdb-944pp -n kube-ops
3. 创立 phpldap deployments svc 服务
cat <<EOF > ldap-phpldapadmin.yaml
kind: Deployment
apiVersion: apps/v1
metadata:
name: ldap-phpldapadmin
namespace: kube-ops
labels:
app: ldap-phpldapadmin
annotations:

app: ldap-phpldapadmin-svc
spec:

port: 80
protocol: TCP
targetPort: 80
selector:
app: ldap-phpldapadmin
EOF
kubectl apply -f ldap-phpldapadmin.yaml
kubectl get svc -n kube-ops
4. 创立 ingress 代理
cat <<EOF > traefik-ldap.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ldap-ui
namespace: kube-ops
annotations:
kubernetes.io/ingress.class: traefik
traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
rules:
- host: ldap.xxx.com
http:
paths:
- pathType: Prefix
path: /
backend:
service:
name: ldap-phpldapadmin-svc
port:
number: 80
EOF
kubectl apply -f traefik-ldap.yaml
5. 验证
登陆 https://ldap.xxxx.com
Login DN: |
---|
cn=admin,dc=xxx,dc=com
Password:
零碎变量中的:LDAP_ADMIN_PASSWORD
深深的感触到了远古页面的感觉:
先整到这里,而后测试一下 spinnaker 集成。快一年没有搞了,整通了一起测试写一下 spinnaker jenkins 等利用的集成!
