Net Core Docker 容器部署，修改，保存

运行镜像

[root@localhost opt]# docker run -itd -p 80:80 microsoft/dotnet:latest

查看运行的docker

[root@localhost opt]# docker ps
CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS              PORTS                NAMES
f3aff5ca8aa3        microsoft/dotnet:latest   "bash"              21 seconds ago      Up 17 seconds       0.0.0.0:80->80/tcp   upbeat_kapitsa

拷贝代码到容器的/opt目录，然后进入之容品

[root@localhost dockernet]# docker cp app f3aff5ca8aa3:/opt
[root@localhost dockernet]# 
[root@localhost dockernet]# 
[root@localhost dockernet]# docker exec -it f3aff5ca8aa3 /bin/bash
root@f3aff5ca8aa3:/# cd /opt
root@f3aff5ca8aa3:/opt# ls
app

到程序目录后运行

root@f3aff5ca8aa3:/opt/app# dotnet PhoneCard.dll

成功运行

把修改的容器保存为镜像

[root@localhost dockernet]# docker commit f3aff5ca8aa3 mynetweb
sha256:ebd813a36273ccd6dab11ffe4eab9ff3da01b4848c97b3ac9eb7ee170b001a72
[root@localhost dockernet]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mynetweb            latest              ebd813a36273        7 seconds ago       1.76GB

进入容器启动，可以看到两个正在运行的容器

[root@localhost dockernet]# docker run -itd -p 8080:80 mynetweb 
[root@localhost dockernet]# docker ps
CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS              PORTS                  NAMES

[root@localhost dockernet]# docker exec -it 685a6c44c03b /bin/bash
root@685a6c44c03b:/# cd /opt
root@685a6c44c03b:/opt# ls
app
root@685a6c44c03b:/opt# cd app

启动后成功运行

root@685a6c44c03b:/opt/app# dotnet PhoneCard.dll

 保存容器为文件

[root@localhost dockernet]# docker export 685a6c44c03b > docker1.tar                      
[root@localhost dockernet]# ls
app  docker1.tar  Dockerfile

 导入容器

docker import - docker1 < docker1.tar
