Docker使用记录
-
查看当前容器/镜像
-
1 2
docker images docker ps
-
-
下载镜像
-
最新版本下载
- 发布则把下面的
pull改成push
1
docker pull * - 发布则把下面的
-
指定版本下载
1
docker pull []:version -
下载所有版本
1
docker pull -a []
-
-
使用镜像
-
docker为容器，run相当于启动一个沙箱，我们在沙箱中运行某个指令.
1
docker run []:[version] COMMAND
-
-
删除镜像
-
1 2
docker rmi [-f] liuml07/giri #-f为强制删除
-
2020.02.09更新
若出现下述情况，则需要我们通过管理员权限运行.
1
Got permission denied while trying to connect to the Docker daemon socket at uni x:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/images/jso n: dial unix /var/run/docker.sock: connect: permission denied
-
将本地文件添加到镜像中
- 使用docker命令
- 利用
docker ps -a可以看到容器的ID 拷贝一张图片到容器的workspace目录下 docker cp /home/img_666.jpg xxx:/路径
- 利用
-
使用dockerfile
-
1 2 3
FROM nginx # 利用docker hub中nginx镜像 ADD ./workspace/img_666.jpg workspace/ # 添加一张图片 WORKDIR /workspace # 设定工作目录
-
- 使用docker命令
-
使用commit命令container打包成镜像
也可以使用Dockerfile打包
-
1
docker commit -a "MetaNetworks" -m "OmpTG Online" 768a1e370dce omptg-online:v1
-a：作者-m：镜像名称768a1e370dce：container的ID，可以通过docker container ls查看
-
-
启动image
-
1
docker run --name omptg-online -dit -P -p 8000:80 -p 8888:8888 omptg-online:v1 /bin/bash start.sh
-
-d：后台启动 -
-t：为容器重新分配一个伪输入终端，通常与-i同时使用 -
-i：以交互模式启动 -
-P：随机分配暴露的端口号 -p：设备的端口：container的端口映射
-
在container内的操作一定要少！！！否则根据docker层数关系管理，镜像会过大！
