一、下載nginx映象:
[[email protected] nginx]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
cfl.io/cfl-account-dubbo-api latest afc03cac5e57 2 days ago 670 MB
cfl.io/cfl-account-dubbo-user latest 10524a6c1f4e 2 days ago 697 MB
docker.io/zookeeper latest 29d319df9c13 6 days ago 149 MB
docker.io/nginx latest c82521676580 3 weeks ago 109 MB
docker.io/java latest d23bdf5b1b1b 19 months ago 643 MB
[ [email protected] nginx]#
二、啟動nginx設定檔案掛載:
1、在宿主機器新建資料夾
/data/docker/nginx/html (靜態資料夾)
/data/docker/nginx/logs (日誌資料夾)
2、在宿機器新建檔案(進入nginx映象內,拷貝出來一份)
/data/docker/nginx/nginx.conf
/data/docker/nginx/conf.d/default.conf
3、修改/data/docker/nginx/nginx.conf
upstream server_account_api {
server t01:8001 weight=1;
server t02:8001 weight=1;
}
4、修改/data/docker/nginx/conf.d/default.conf
location / {
proxy_pass http://server_account_api;
}
5、啟動
--name 名稱
-p 宿主機埠:映象內埠
--link=需訪問的已啟動映象名稱:nginx.conf配置檔案中的別名
-v 掛載到宿主機器資料夾或檔案:nginx內被掛載的資料夾或檔案
docker run -d --name nginx -p 80:80 --link=account-api:t01 --link=account-api-2:t02 -v /data/docker/nginx/html:/usr/share/nginx/html -v /data/docker/nginx/nginx.conf:/etc/nginx/nginx.conf -v /data/docker/nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf -v /data/docker/nginx/logs:/var/log/nginx c82521676580
[[email protected] nginx]# docker ps

6、在瀏覽器中訪問宿主機器
