ArgoCD从内网的GitLab Repo部署应用
本文将讲解中我的home lab（一个访问受限的环境中），使用ArgoCD 部署一个gitlab repo的全部过程
Home lab Env
在home lab中， 有如下服务运行着
GitLab server:
K8s Cluster
我有一个3节点的k8s集群： 一个maste，2个node
❯ kubectl cluster-info
Kubernetes control plane is running at https://192.168.1.101:6443
CoreDNS is running at https://192.168.1.101:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
❯ kubectl get no
NAME STATUS ROLES AGE VERSION
k8s-master Ready control-plane 25d v1.36.0
k8s-worker1 Ready <none> 25d v1.36.0
k8s-worker2 Ready <none> 25d v1.36.0
ArgoCD
ArgoCD 已经部署到K8S集群里面了
❯ argocd version
argocd: v3.4.3+1801122
BuildDate: 2026-05-28T12:02:57Z
GitCommit: 1801122b4391cad4961301f787006dc9a88c2dd3
GitTreeState: clean
GoVersion: go1.26.0
Compiler: gc
Platform: linux/amd64
argocd-server: v3.4.3
ArgoCD Web UI:
https://192.168.1.101:31157/
准备 repo
创建 GitLab repo
Git repo name: argocd-demo-gl
Repo GitLab URL http://192.168.1.4:8080/yahoon/argocd-demo-gl
Set the repo to public
Clone to local dir:
❯ git clone ssh://git@192.168.1.4:2222/yahoon/argocd-demo-gl.git
Cloning into 'argocd-demo-gl'...
填充git repo内容
目录结构如下
❯ tree .
.
├── container-image
│ └── argocd-demo
│ ├── Containerfile
│ ├── index.html
│ └── README.md
├── k8s-apps
│ └── argocd-demo
│ ├── deployment.yaml
│ └── service.yaml
└── README.md
内容说明
- container-image： 放image, 我用
argocd-demo-gl做名字- 主要效果是http/80 显示html 内容
Hello, This is Yahoon's ArgoCD Demo from Local GitLab!
- 主要效果是http/80 显示html 内容
- k8s-apps: 在k8s上部署的resource,主要是service
argocd-demo-go
Git提交 & push
你可以访问所有代码在这个仓库: https://github.com/yahoon/argocd-demo-gl
准备 image repo
在Quay上创建 public repo: https://quay.io/repository/yahoon/argocd-demo-gl
准备image
我用 argocd-demo-gl做名字
❯ cd container-image/argocd-demo/
❯ podman build -t quay.io/yahoon/argocd-demo-gl:v1 .
本地测试image
❯ podman run --rm -d -P quay.io/yahoon/argocd-demo-gl:v1
❯ podman ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
226a6d5f6589 quay.io/yahoon/argocd-demo-gl:v1 nginx -g daemon o... 2 seconds ago Up 2 seconds 0.0.0.0:44137->80/tcp intelligent_banzai
❯ curl localhost:44137
Hello, This is Yahoon's ArgoCD Demof rom Local GitLab!
推送image
❯ podman login -u='yahoon' -p='yahoon-quay-password' quay.io
❯ podman push quay.io/yahoon/argocd-demo-gl:v1
在ArgoCD UI 上部署app
Create app
Login Argo UI: https://192.168.1.101:31157/
点击 + NEW APP，填写：
General 区
- Application Name:
argocd-demo-gl - Project:
default - Sync Policy:
Manual
Sync Options 区（点开折叠）- 勾选
Auto-Create Namespace
- 勾选
Source 区
- Repository URL:
http://192.168.1.4:8080/yahoon/argocd-demo-gl.git - Revision:
HEAD - Path:
k8s-apps/argocd-demo
Destination 区
- Cluster URL: 下拉选择
in-cluster (https://kubernetes.default.svc) - Namespace:
argocd-ademo-gl
点击右上角 CREATE
Sync app
点开app页面，点sync, 等一会就成功了
在CLI下面查看:
❯ oc get app -n argocd
NAME SYNC STATUS HEALTH STATUS
argocd-demo-gl Synced Healthy
❯ oc get all -n argocd-demo-gl
NAME READY STATUS RESTARTS AGE
pod/argocd-demo-79d888c774-4mwpx 1/1 Running 0 7s
pod/argocd-demo-79d888c774-6fshr 1/1 Running 0 7s
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/argocd-demo-gl ClusterIP 10.109.8.250 <none> 80/TCP 7s
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/argocd-demo 2/2 2 2 7s
NAME DESIRED CURRENT READY AGE
replicaset.apps/argocd-demo-79d888c774 2 2 2 7s
Test the app
❯ kubectl run curl-test -n argocd-demo-gl --rm -it --image=quay.io/curl/curl --restart=Never -- \
curl http://argocd-demo-gl.argocd-demo-gl.svc.cluster.local
// 应该返回 "Hello, This is Yahoon's ArgoCD Demo"。
端口转发
❯ kubectl port-forward -n argocd-demo-gl svc/argocd-demo-gl 8081:80
在web browser 里访问 http://localhost:8081/
总结
总体实现就是Argo直接从git repo来部署应用到k8s上，应用所有的更改都要通过git 来实现=》 这也就是 GitOps的意义所在了！
