21天华为云:第三天

Day 3 手把手教您运行一个镜像

1. 点击上节课创建的 tank 镜像
2. 
   先获取仓库权限
   

本地pull
docker pull swr.cn-north-1.myhuaweicloud.com/ckeny/demo_tank:v1.0.1

查看是否PULL下镜像
docker images | grep tank

2 上传镜像
这些镜像在后续的课程操作中需要使用，下载方法与第一步介绍相同，直接在已登陆的窗
口中，执行下面这些命令行即可。
docker pull swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-productpage-v1:1.5.0

docker pull swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-details-v1:1.5.0

docker pull swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-ratings-v1:1.5.0

docker pull swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-reviews-v1:1.5.0-v2

docker pull swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-reviews-v1:1.5.0-v3

以上命令完成后，再执行docker images|grep istio 查看以上镜像是否已完全下载到本地。

上传公共镜像到自己仓库:

将以上镜像逐个上传到指定的 组织名称(ckeny) 下
1
docker tag swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-productpage-v1:1.5.0 swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-productpage-v1:1.5.0

sudo docker push swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-productpage-v1:1.5.0

2
docker tag swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-details-v1:1.5.0 swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-details-v1:1.5.0

sudo docker push swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-details-v1:1.5.0

3
docker tag swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-ratings-v1:1.5.0 swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-ratings-v1:1.5.0

sudo docker push swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-ratings-v1:1.5.0

4
docker tag swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-reviews-v1:1.5.0-v2 swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-reviews-v1:1.5.0-v2

sudo docker push swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-reviews-v1:1.5.0-v2

5
docker tag swr.cn-north-1.myhuaweicloud.com/istio-sample/examples-bookinfo-reviews-v1:1.5.0-v3 swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-reviews-v1:1.5.0-v3

sudo docker push swr.cn-north-1.myhuaweicloud.com/ckeny/examples-bookinfo-reviews-v1:1.5.0-v3

运行镜像:

docker run --name tank -d -p 8080:80 8a528e9553c6

挂载镜像并运行容器访问
docker cp tank:/etc/nginx/conf.d/default.conf ./
vim default.conf
PS: 修改listen的端口号8080
docker run -d –name tank1 -p 8081:8080 -v $PWD/default.conf:/etc/nginx/conf.d/default.conf 8a528e9553c6

总结对比昨天,主要今天使用的挂载外部配置文件来运行Docker
