## README

# 创建git
```
mkdir geek_cloud_native
cd geek_cloud_native
git init
touch README.md
git add README.md
git commit -m "first commit"
git remote add origin https://gitee.com/ceagle/geek_cloud_native.git
git push -u origin "master"
```
# 编译二级制
```bash 
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o bin/amd64 .
```
# 构建镜像
```bash
docker build -f Dockerfile -t go_httpserver .

```
# 删除已经启动的同名容器
```bash
docker rm -f go_httpserver
```
# 启动容器
```bash
docker run -d -ti --name go_httpserver --net=host go_httpserver 
docker run -d -ti --name go_httpserver 5a69f717e700 
```

# 登录容器
```bash
docker exec -ti go_httpserver bash
```

验证web服务器

```bash

启动web服务器
root@ubuntu:/# ./httpserver 
VERSION NO CONFIGED
127.0.0.1:8080|127.0.0.1:54406|200

访问web服务器
curl http://127.0.0.1:8080/healthz
root@ubuntu:/# curl http://127.0.0.1:8080/healthz
Hello,healthz
request 中带的 header 写入 response header:

# 打标签
```bash
docker tag d7c71cba5681 docker.io/ceagle/httpserver:v1.0
或者
docker tag d7c71cba5681 ceagle/httpserver:v1.0
```
# 推送镜像到 hub.docker.com
```bash
docker push docker.io/ceagle/httpserver:v1.0
或者
docker push ceagle/httpserver:v1.0
```

# httpserver 镜像地址
```bash
https://hub.docker.com/r/ceagle/httpserver
```




# 制作 ubuntu go环境
```bash
docker run -d -ti --name ubuntu_init ubuntu
docker exec -ti ubuntu_init bash
```
ubuntu 更换源，这里是阿里源
```bash
sudo tee /etc/apt/sources.list <<-'EOF'

保存ubuntu镜像
```sh
docker commit 08a2c8bf266f ceagle/ubuntu20.04.3-go1.20.2:v1.0
```

----------------------------------------------------------------
make 安装
```bash 
sudo apt-get install make

```

# 作业
## 构建本地镜像

https://registry.hub.docker.com/_/registry/

```bash
# 拉取镜像
docker pull registry

# 本地搭建 映射端口，容器内默认为：5000
docker run -d -p 5000:5000 registry
```

本地镜像上传到私有registry

```bash
# 打tag
docker tag nginx:alpine 127.0.0.1:5000/nginx:alpine
# push 到私有仓库
docker push 127.0.0.1:5000/nginx:alpine
# 删除本地镜像
docker rmi  127.0.0.1:5000/nginx:alpine
# 从本地仓库拉取镜像
docker pull 127.0.0.1:5000/nginx:alpine
```

## 编写 Dockerfile 将模块二作业编写的 httpserver 容器化
见Dockerfile
## 将镜像推送至 docker 官方镜像仓库
见Makefile
`make release`
## 通过 docker 命令本地启动 httpserver
`docker run -d --name=local_httpserver --net=host go_httpserver`
## 通过 nsenter 进入容器查看 IP 配置
```bash
ceagle@ubuntu:~$ docker inspect local_httpserver|grep -i pid
"Pid": 4217,
"PidMode": "",
"PidsLimit": null,
ceagle@ubuntu:~$ nsenter -t 4217 -n ip a
