1. Installation
vim /lib/systemd/system/docker.serviceModify as follows
FROM java:8 VOLUME /tmp ADD /target/sso_test-0.0.1-SNAPSHOT.jar sso_test.jar EXPOSE 9999 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/sso_test.jar"]The format is FROM
VOLUME
The format is VOLUME ["/data"]. Create a mount point that can be mounted from the local host or other containers. It is generally used to store databases and data that need to be maintained.ADD
The format is ADDEXPOSE
The format is EXPOSEENTRYPOINT
Two formats:- ##ENTRYPOINT ["executable", "param1", "param2"]
- ENTRYPOINT command param1 param2 (executed in shell)
- Configure the command to be executed after the container is started, and cannot be overridden by the parameters provided by docker run.
Each Dockerfile can only have one ENTRYPOINT. When multiple are specified, only the last one will take effect.

docker中rm和rmi的区别:rm命令用于删除一个或者多个容器,而rmi命令用于删除一个或者多个镜像;rm命令的语法为“docker rm [OPTIONS] CONTAINER [CONTAINER...]”,rmi命令的语法为“docker rmi [OPTIONS] IMAGE [IMAGE...]”。

docker官方镜像有:1、nginx,一个高性能的HTTP和反向代理服务;2、alpine,一个面向安全应用的轻量级Linux发行版;3、busybox,一个集成了三百多个常用Linux命令和工具的软件;4、ubuntu;5、PHP等等。

docker容器重启后数据会丢失的;但是可以利用volume或者“data container”来实现数据持久化,在容器关闭之后可以利用“-v”或者“–volumes-from”重新使用以前的数据,docker也可挂载宿主机磁盘目录,用来永久存储数据。

docker对于小型企业、个人、教育和非商业开源项目来说是免费的;2021年8月31日,docker宣布“Docker Desktop”将转变“Docker Personal”,将只免费提供给小型企业、个人、教育和非商业开源项目使用,对于其他用例则需要付费订阅。

docker能安装oracle。安装方法:1、拉取Oracle官方镜像,可以利用“docker images”查看镜像;2、启动容器后利用“docker exec -it oracle11g bash”进入容器,并且编辑环境变量;3、利用“sqlplus /nolog”进入oracle命令行即可。

解决方法:1、停止docker服务后,利用“rsync -avz /var/lib/docker 大磁盘目录/docker/lib/”将docker迁移到大容量磁盘中;2、编辑“/etc/docker/daemon.json”添加指定参数,将docker的目录迁移绑定;3、重载和重启docker服务即可。

AUFS是docker最早支持的存储引擎。AUFS是一种Union File System,是文件级的存储驱动,是Docker早期用的存储驱动,是Docker18.06版本之前,Ubuntu14.04版本前推荐的,支持xfs、ext4文件。

docker中的镜像会自动更新;可以利用Watchtower工具来自动更新镜像,Watchtower是一个可以监控正在运行的容器镜像是否更新的工具,当本地镜像与远程镜像有差异的时候,可以自动使用当前容器的运行参数以新镜像重新创建一个新的容器,并删除旧的容器。
