docker-compose容器
部署nmt---nginx+compose+tomcat项目
使用基础的docker指令来创建镜像，实现项目的发布。
Dockerfile--->docker-compose
背景：在一台主机内实现容器的编排，发布考试系统
前端部署
1.安装docker
[root@docker0 ~]# sh docker.sh
2.编辑daemon.json文件---设置仓库镜像
vim /etc/docker/daemon.json
{
"registry-mirrors":[
"GitHub - DaoCloud/public-image-mirror: 很多镜像都在国外。比如 gcr 。国内下载很慢，需要加速。致力于提供连接全世界的稳定可靠安全的容器镜像服务。",
"https://docker.mirrors.ustc.edu.cn",
]
}
3.开启docker服务
[root@docker0 ~]# systemctl daemon-reload
[root@docker0 ~]# systemctl start docker
4.拉取nginx镜像
[root@docker0 ~]# docker pull nginx
Using default tag: latest
latest: Pulling from library/nginx
e4fff0779e6d: Pull complete
2a0cb278fd9f: Pull complete

Status: Downloaded newer image for nginx:latest
docker.io/library/nginx:latest
查看镜像
[root@docker0 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest 5ef79149e0ec 2 weeks ago 188MB
5.创建nginx容器
[root@docker0 ~]# docker run -itd -p80:80 nginx:latest
c9fa7a0cbb13a3dd627b94c28f76ce1802fa391652832ad875782c8d073e6ff9
[root@docker0 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c9fa7a0cbb13 nginx:latest "/docker-entrypoint...." 17 seconds ago Up 15 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp affectionate_vaughan
[root@docker0 ~]# curl localhost
<!DOCTYPE html>
<html>
<head>

<p><em>Thank you for using nginx.</em></p>
</body>
</html>
在容器启动之后，nginx服务酒店发布了
[root@docker0 ~]# docker exec -it c9fa ls /usr/share/nginx/html
50x.html index.htm
7.创建一个目录，将前端和后端的所以资料放在这里
[root@docker0 ~]# mkdir project_exam_system/
[root@docker0 ~]# cd project_exam_system/
[root@docker0 project_exam_system]# mkdir web
[root@docker0 project_exam_system]# rz -E
rz waiting to receive.
[root@docker0 project_exam_system]# ls web/
dist
[root@docker0 project_exam_system]# ls web/dist/
assets favicon.ico index.html
8.创建容器，映射端口，挂载目录
删除容器c9fa
[root@docker0 project_exam_system]# docker stop c9fa
c9fa
[root@docker0 project_exam_system]# docker rm c9fa
c9fa
创建新容器
[root@docker0 project_exam_system]# docker run -itd -p80:80 -v /root/project_exam_system/web/dist/:/usr/share/nginx/html/ nginx:latest
b46e530213e011ca30c84549aabc42db21cef193ef8d426ed1c2a6f5fe818d44
9.刷新浏览器

4.将外部资源复制到容器内
[root@docker0 ~]# docker cp --help
Usage: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH
Copy files/folders between a container and the local filesystem
Use '-' as the source to read a tar archive from stdin
and extract it to a directory destination in a container.
Use '-' as the destination to stream a tar archive of a
container source to stdout.
Aliases:
docker container cp, docker cp
Options:
-a, --archive Archive mode (copy all uid/gid information)
-L, --follow-link Always follow symbol link in SRC_PATH
-q, --quiet Suppress progress output during copy.
Progress output is automatically suppressed
if no terminal is attached
