Argo CD是Kubernetes的声明性GitOps连续交付工具。

前提条件

• Installed kubectl command-line tool.
• Have a kubeconfig file (default location is ~/.kube/config).
• CoreDNS. Can be enabled for microk8s by microk8s enable dns && microk8s stop && microk8s start

安装手顺

1. Install Argo CD

完整版安装（包含后台管理 ui）

kubectl create namespace argocd

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

无 argocd ui 安装

kubectl create namespace argocd

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-c

2. 下载安装 Argo CD CLI

在可访问 k8s 的 linux 机器安装 cli

curl -sSL -o argocd-linux-amd64 https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64

sudo install -m 555 argocd-linux-amd64 /usr/local/bin/argocd

rm argocd-linux-amd64

3. 访问Argo CD API Server

• 在云部署 k8s 的环境可通过 load balance 访问 argocd apiserver

kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'

• 通过 port forward转发到本地 linux 端口访问 argocd apiserver

kubectl port-forward svc/argocd-server -n argocd 8080:443

• 通过 ingress 访问argocd apiserver

前提必须安装 nginx ingress

ingress.yml

apiVersion: networking.k8s.io/v1

kind: Ingress

metadata:

name: argocd-server-ingress

namespace: argocd

annotations:

kubernetes.io/ingress.class: nginx

nginx.ingress.kubernetes.io/force-ssl-redirect: "true"

nginx.ingress.kubernetes.io/ssl-passthrough: "true"

spec:

rules:

- host: argocd.example.com

http:

paths:

- path: /

pathType: Prefix

backend:

service:

name: argocd-server

port:

name: https

‬kubectl apply -f ingress.yml

4. 使用CLI 登录 argocd

• 初始化密码

$ argocd admin initial-password -n argocd

执行结果返回临时密码:

6Vv8LFxzid2RHsWo

• 登录 argocd

$argocd login localhost:8080

WARNING: server certificate had error: x509: certificate is valid for localhost, argocd-server, argocd-server.argocd, argocd-server.argocd.svc, argocd-server.argocd.svc.cluster.local,Proceed insecurely (y/n)? y

Username: admin

Password:

'admin:login' logged in successfully

Context 'afa4387' updated

• 更新密码

argocd account update-password

5. Register A Cluster To Deploy Apps To 注册 k8s 集群

获取集群

kubectl config get-contexts -o name

argocd cluster add 集群

安装完后，就可创建 app，关联 git
