部署基础镜像

1
sudo docker run -it -d -p 9980:8080 -e PASSWORD='password'   -u "$(id -u):$(id -g)"  codercom/code-server:4.14.1-bullseye

安装一些软件和插件

对修改过的镜像进行打包

重新打包修改后的镜像

1.将容器保存为镜像

1
sudo docker commit 3b64c2a1c5bf test/code-server:4.14.1-bullseye

2.将镜像打包

1
sudo docker save -o testcodeserver4.14.1bullseye.tar test/code-server:4.14.1-bullseye

3.将镜像包压缩

1
sudo tar -zcvf testcodeserver4.14.1bullseye.tar.gz testcodeserver4.14.1bullseye.tar

另一种打包压缩方法(发现这种方法压缩后体积更小)

1
docker save test/code-server:4.14.1-bullseye | gzip > testcodeserver4.14.1bullseye.tar.gz

将修改过的镜像解压以及镜像载入

# 压缩包解压，得到tar格式的镜像包
tar -zxvf testcodeserver4.14.1bullseye.tar.gz 
# 镜像载入
#1. tar镜像载入
sudo dcoker load -i testcodeserver4.14.1bullseye.tar
#2. gz镜像载入
sudo docker load -i testcodeserver4.14.1bullseye.tar.gz
# 查看镜像
sudo docker images
