ArgoCD从内网的GitLab Repo部署应用

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:

准备 repo

创建 GitLab repo

Git repo name:argocd-demo-gl

Repo GitLab URLhttp://192.168.1.4:8080/yahoon/argocd-demo-gl

Set the repo topublic

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!
• k8s-apps: 在k8s上部署的resource,主要是serviceargocd-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

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

BASH 复制 全屏

在web browser 里访问 http://localhost:8081/
