使用 GitLab CI 与 Argo CD 实践 GitOps-will的博客

argocd简介

Argo CD是用于Kubernetes的声明性GitOps持续交付工具，遵循GitOps模式，该模式使用Git仓库作为定义所需应用程序状态的真实来源。

Argo CD可在指定的目标环境中自动部署所需的应用程序状态，应用程序部署可以在Git提交时跟踪对分支，标签的更新，或固定到清单的特定版本。

argoCD支持的Kubernetes 配置清单包括helm charts、kustomize或纯YAML/json文件等。

添加helm仓库

helm repo add argo https://argoproj.github.io/argo-helm

部署argocd

helm install argocd argo/argo-cd \
  --namespace=argocd --create-namespace \
  --set global.image.repository="argoproj/argocd" \
  --set dex.image.repository="dexidp/dex" \
  --set server.service.type=NodePort \
  --set server.service.nodePortHttp=30085 \

获取admin用户密码

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

部署gitlabCI

安装gitlab

docker run -d --name gitlab \
  --restart always \
  --hostname gitlab.prod.cloudcele.com \
  -p 8929:8929 -p 2289:22 \
  -e GITLAB_OMNIBUS_CONFIG="external_url 'http://gitlab.prod.cloudcele.com:8929'; gitlab_rails['gitlab_shell_ssh_port'] = 2289; gitlab_rails['initial_root_password'] = 'Gitlab@123';" \
  -v /data/gitlab/config:/etc/gitlab \
  -v /data/gitlab/logs:/var/log/gitlab \
  -v /data/gitlab/data:/var/opt/gitlab \
  gitlab/gitlab-ce:14.1.5-ce.0

安装gitlab-runner

helm install gitlab-runner \
  --namespace=gitlab-runner \
  --create-namespace \
  --version=0.31.0 \
  --set image=gitlab/gitlab-runner:alpine-v14.1.0 \
  --set runners.helpers.image="gitlab/gitlab-runner-helper:x86_64-8925d9a0" \
  --set gitlabUrl=http://10.0.0.5:8929 \
  --set runnerRegistrationToken="3XxYzq83EhVigW6SAw8Y" \
  --set rbac.create=true \
  --set rbac.clusterWideAccess=true \
  --set privileged=true \
  --set runners.name=k8s-helm-runner \
  --set runners.tags=k8s-runner \
  --set runners.runUntagged=true \
