2022-03-12：k8s如何搭建gogs+drone实现自动化部署cicd，yaml如何写？

答案2022-03-12：

需要安装docker和k3s，见 docker和k3s，k3s不需要依赖docker，但是drone-run-docker依赖docker，所以一定要安装docker。

第一种方法：

yaml如下，需要把192.168.204.13替换成自己电脑的ip：

访问http://192.168.204.13:10080/，创建账号，创建项目。然后git clone http://192.168.204.13:10080/moonfddgroup/testdemo.git。在这里插入图片描述写好.drone.yml文件，然后push上去。.drone.yml文件内容如下：

kind: pipeline
type: docker 
name: dev

steps:
  - name: build
    image: golang
    pull: if-not-exists
    environment:
      ***: https://***.cn,direct
      CGO_ENABLED: 0
      GO111MODULE: on
      GOOS: linux
      GOARCH: amd64
    commands:
      - go env

trigger:
  branch:
  - master

push上去，drone里的结果如下：在这里插入图片描述

第二种方法：

1.先copy项目

git clone https://gitee.com/moonfdd/k8syaml.git
cd k8syaml/droneci

2.修改Makefile文件，把192.168.204.13 改成自己电脑IP：


.PHONY: all

all: build

build:
	k3s kubectl apply -f mysql.yaml
	k3s kubectl apply -f registry.yaml
	k3s kubectl apply -f phpmyadmin.yaml
	cp gogs.yaml gogs2.yaml
	sed -i "s/moonfddmyip/192.168.204.13/g" gogs2.yaml # 192.168.204.13 需要替换成宿主机IP
	k3s kubectl apply -f gogs2.yaml
	rm -rf gogs2.yaml
	k3s kubectl apply -f drone.yaml
	k3s kubectl apply -f drone-runner-ssh.yaml
	k3s kubectl apply -f drone-runner-docker.yaml
test:
	pwd

clean:
	k3s kubectl delete -f mysql.yaml
	k3s kubectl delete -f registry.yaml
	k3s kubectl delete -f phpmyadmin.yaml
	k3s kubectl delete -f gogs.yaml
	k3s kubectl delete -f drone.yaml
	k3s kubectl delete -f drone-runner-ssh.yaml
	k3s kubectl delete -f drone-runner-docker.yaml

然后make build。

make build # 搭建 ci/cd 环境
make clean # 卸载 ci/cd 环境
