## 一:环境准备
#### 1.kubernetes集群
集群环境检查
```shell
[root@master ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
master Ready control-plane,master 17d v1.23.1
node-1 Ready <none> 17d v1.23.1
node-2 Ready <none> 17d v1.23.1
node-3 Ready <none> 17d v1.23.1
```
注意node节点的运行内存需要大于5G以上
#### 2.harbor仓库
仓库检查
<img src="%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220513232903669.png" alt="image-20220513232903669" style="zoom:50%;" />
#### 3.NFS提供PVC
```shell
[root@nfs-harbor ~]# exportfs -rv
exporting *:/data/storage/k8s/gitlab/gitlab
exporting *:/data/storage/k8s/gitlab/redis
exporting *:/data/storage/k8s/gitlab/postgresql
```
## 二gitlab-ce部署
#### 1.创建命名空间
```shell
[root@master gitlab]# kubectl create namespace kube-ops
```
#### 2.postgresql数据库

注意gitlab启动较慢我们需要耐心等待
![image-20220513235023237](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220513235023237.png)

## 三gitlab-runner部署
#### 1.创建configmap
创建config-configmap.yaml文件
```shell
[root@master gitlab-runner]# cat config-configmap.yaml
apiVersion: v1
data:
REGISTER_NON_INTERACTIVE: "true"
REGISTER_LOCKED: "false"
METRICS_SERVER: "0.0.0.0:9100"
CI_SERVER_URL: "http://10.0.0.220:30004/ci" # k8s内gitlab服务的通信地址格式:svc.namespace.svc.cluster.local, 同时加上/ci这个prefix这里也可以使用外网访问地址
RUNNER_REQUEST_CONCURRENCY: "4"
RUNNER_EXECUTOR: "kubernetes"
KUBERNETES_NAMESPACE: "kube-ops" # 服务运行的namespace
KUBERNETES_PRIVILEGED: "true"
KUBERNETES_CPU_LIMIT: "1"
KUBERNETES_MEMORY_LIMIT: "1Gi"
KUBERNETES_SERVICE_CPU_LIMIT: "1"
KUBERNETES_SERVICE_MEMORY_LIMIT: "1Gi"
KUBERNETES_HELPER_CPU_LIMIT: "500m"
KUBERNETES_HELPER_MEMORY_LIMIT: "100Mi"
KUBERNETES_PULL_POLICY: "if-not-present"
KUBERNETES_TERMINATIONGRACEPERIODSECONDS: "10"
KUBERNETES_POLL_INTERVAL: "5"
KUBERNETES_POLL_TIMEOUT: "360"
kind: ConfigMap
metadata:
labels:
app: gitlab-ci-runner
name: gitlab-ci-runner-cm
namespace: kube-ops
```
创建scripts-configmap.yaml文件
```shell
[root@master gitlab-runner]# cat scripts-configmap.yaml
apiVersion: v1
data:
run.sh: |
#!/bin/bash
unregister() {
kill %1
echo "Unregistering runner ${RUNNER_NAME} ..."
/usr/bin/gitlab-ci-multi-runner unregister -t "$(/usr/bin/gitlab-ci-multi-runner list 2>&1 | tail -n1 | awk '{print $4}' | cut -d'=' -f2)" -n ${RUNNER_NAME}
exit $?
}
trap 'unregister' EXIT HUP INT QUIT PIPE TERM
echo "Registering runner ${RUNNER_NAME} ..."
/usr/bin/gitlab-ci-multi-runner register -r ${GITLAB_CI_TOKEN}
sed -i 's/^concurrent.*/concurrent = '"${RUNNER_REQUEST_CONCURRENCY}"'/' /home/gitlab-runner/.gitlab-runner/config.toml
echo "Starting runner ${RUNNER_NAME} ..."
/usr/bin/gitlab-ci-multi-runner run -n ${RUNNER_NAME} &
wait
kind: ConfigMap
metadata:
labels:
app: gitlab-ci-runner
name: gitlab-ci-runner-scripts
namespace: kube-ops
```
创建configmap
```shell
[root@master gitlab-runner]# kubectl create -f scripts-configmap.yaml
[root@master gitlab-runner]# kubectl create -f config-configmap.yaml
```
查看:
```shell
[root@master gitlab-runner]# kubectl get configmap -n kube-ops
NAME DATA AGE
gitlab-ci-runner-cm 18 22m
gitlab-ci-runner-scripts 1 21m
```
#### 2.创建secret
需要创建一个Secret用来存储gitlab的token
创建secret.yaml文件
```shell
[root@master gitlab-runner]# cat secret.yaml
apiVersion: v1
kind: Secret
metadata:
name: gitlab-ci-token
namespace: kube-ops
labels:
app: gitlab-ci-runner
data:
GITLAB_CI_TOKEN: R1IxMzQ4OTQxVVZVWS1yUjh4YXl6aE1zaVp3eDU= # 这是base64加密Gitlab runner token之后的字符串
```
生产tokne
```shell
[root@master gitlab-runner]# echo -n 'GR1348941UVUY-rR8xayzhMsiZwx5' | openssl base64
R1IxMzQ4OTQxVVZVWS1yUjh4YXl6aE1zaVp3eDU=
```
创建secret
```shell
[root@master gitlab-runner]# kubectl create -f secret.yaml
```
查看:
```shell
[root@master gitlab-runner]# kubectl get secret -n kube-ops
NAME TYPE DATA AGE
default-token-5xql2 kubernetes.io/service-account-token 3 24h
gitlab-ci-token Opaque 1 18m
gitlab-ci-token-dwvd5 kubernetes.io/service-account-token 3 10m
```
#### 3.创建ServiceAccount
创建一个`ServiceAccount`来有足够的权限做一些事情,因此我们创建一个`gitlab-ci`的`ServiceAccount`
创建ServiceAccount、Role、RoleBinding文件
```shell
[root@master gitlab-runner]# cat rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: gitlab-ci
namespace: kube-ops
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: gitlab-ci
namespace: kube-ops
rules:
- apiGroups: [""]
resources: ["*"]
verbs: ["*"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: gitlab-ci
namespace: kube-ops
subjects:
- kind: ServiceAccount
name: gitlab-ci
namespace: kube-ops
roleRef:
kind: Role
name: gitlab-ci
apiGroup: rbac.authorization.k8s.io
```
创建:
```shell
[root@master gitlab-runner]# kubectl create -f rbac.yaml
```
查看:
```shell
[root@master gitlab-runner]# kubectl get serviceaccount -n kube-ops
NAME SECRETS AGE
default 1 24h
gitlab-ci 1 13m
```
```shell
[root@master gitlab-runner]# kubectl get role -n kube-ops
NAME CREATED AT
gitlab-ci 2022-05-13T16:42:08Z
```
```shell
[root@master gitlab-runner]# kubectl get rolebinding -n kube-ops
NAME ROLE AGE
gitlab-ci Role/gitlab-ci 14m
```
#### 4.创建Statefulset
创建statefulset yaml文件
```shell
[root@master gitlab-runner]# cat statefulset.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: gitlab-ci-runner
namespace: kube-ops
labels:
app: gitlab-ci-runner
spec:
selector:
matchLabels:
app: gitlab-ci-runner
updateStrategy:
type: RollingUpdate
replicas: 1
serviceName: gitlab-ci-runner
template:
metadata:
labels:
app: gitlab-ci-runner
spec:
volumes:
- name: gitlab-ci-runner-scripts
projected:
sources:

ports:
- containerPort: 9100
name: http-metrics
protocol: TCP
volumeMounts:
- name: gitlab-ci-runner-scripts
mountPath: "/scripts"
readOnly: true
restartPolicy: Always
```
创建:
```shell
[root@master gitlab-runner]# kubectl create -f statefulset.yaml
```
查看:
```shell
[root@master gitlab-runner]# kubectl get statefulset -n kube-ops
NAME READY AGE
gitlab-ci-runner 1/1 19m
```
```shell
[root@master gitlab-runner]# kubectl get pod -n kube-ops
NAME READY STATUS RESTARTS AGE
gitlab-696d568999-8zg75 1/1 Running 1 3h2m
gitlab-ci-runner-0 1/1 Running 0 18m
postgresql-cccb54fff-2gczp 1/1 Running 0 3h3m
redis-7786bc4f96-lxhlj 1/1 Running 0 3h2m
```
#### 5.gitlab查看注册Runner服务

## 四gitlab-ce使用
#### 1.配置项目启动邮件
Menu---->your project--->admin(其中一个项目)
![image-20220514140944925](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220514140944925.png)
Configure intergrations---> Add an intergration---> Email on push
![image-20220514141021752](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220514141021752.png)
添加邮箱(可以先测试连接,后添加)

#### 2.关联harbor仓库
仓库地址http://10.0.0.230 这是一个本地地址在kubernetes集群外
Menu---->Admin
![image-20220514141414315](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220514141414315.png)
Settings---->Network
![image-20220514141453504](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220514141453504.png)
找到Outbound requests
![image-20220514141557089](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220514141557089.png)
选择允许本地网络

注意:
以上操作就是解决这个问题Import url is blocked: Requests to the local network are not allowed
Menu---->admin(项目)---->configure intergrations
![image-20220514141749612](%E5%88%A9%E7%94%A8kubernetes%E9%83%A8%E7%BD%B2gitlab-ce.assets/image-20220514141749612.png)
Add an integration---> Harbor

#### 3.CI/CD pipelines
pipelines 管道管道是持续集成、交付和部署的顶级组件作业由runners执行。如果有足够的并发运行者同一阶段的多个作业将并行执行如果一个阶段中的*所有*作业都成功,则管道将进入下一个阶段;如果一个阶段中的任何作业失败,则(通常)不会执行下一个阶段,并且管道会提前结束;一般来说,管道是自动执行的,一旦创建就不需要干预;但是,有时您也可以手动与管道交互
管道包括:
工作:它定义*了*要做什么。例如,编译或测试代码的作业
阶段:定义何时运行作业。例如,在编译代码的阶段之后运行测试的阶段
四个阶段:
一个`build`舞台,有一个工作叫做`compile`
一个`test`阶段,有两个作业称为`test1`和`test2`
一个`staging`舞台,有一个工作叫做`deploy-to-stage`
一个`production`舞台,有一个工作叫做`deploy-to-prod`
#### 4.`.gitlab-ci.yaml`文件:
