## 云原生基础设施之容器入门
打开终端ssh链接后，首先修改镜像源
```
vim /etc/docker/daemon.json
{
"registry-mirrors": [
"https://docker.1panel.live"
]
}
```
wq保存退出，重启docker
```
systemctl daemon-reload
systemctl restart docker
```
实验一
0. 拉取httpd镜像
```
docker pull httpd
```
1. 创建dockerfile文件
```
vim dockerfile
```
2. 输入以下内容
```
FROM httpd
MAINTAINER [email protected]
EXPOSE 80
RUN echo "dockerfile test" > /usr/local/apache2/htdocs/index.html
```
3. 构建镜像
```
docker build -t httpd:v1 .
```
4. 运行容器并映射端口
```
docker run -d -p 80:80 --name httpd-test httpd:v1
```
5. 浏览器访问http://EIP:80并多刷新几次，返回以下即可(考点)
```
dockerfile test
```
实验二
```
# 0. 启用私有镜像仓库容器(监听5000端口)(考点)
docker run -d -p 5000:5000 --name registry registry
# 1. 给本地镜像打标签并推送至私有仓库
docker tag httpd:v1 localhost:5000/httpd:v1
docker push localhost:5000/httpd:v1
# 2. 验证是否上传成功
curl -X GET http://localhost:5000/v2/httpd/tags/list
# 3. 返回结果(考点)
{"name":"httpd","tags":["v1"]}
```
实验三
```
# 1. 暂停容器
docker pause httpd-test
# 2. 恢复容器
docker unpause httpd-test
# 3. 停止容器
docker stop httpd-test
# 4. 重启容器
docker restart httpd-test
# 5. 删除容器
docker stop httpd-test
docker rm httpd-test
# 6. 删除镜像
docker rmi httpd:v1
# 7. 验证返回内容(考点)
Untagged: httpd:v1
```
