Docker-compose needs to be installed
Compose is Docker’s official open source project and needs to be installed!
Docker Compose is a tool used to define and run Docker tools for complex applications. An application system using Docker containers is usually composed of multiple containers. If each microservice has to be started and stopped manually, the efficiency will be low and the amount of maintenance will be heavy. Docker Compose is the official orchestration (Orchestration) project of Docker One is responsible for quickly deploying distributed applications.
Use Docker Compose to manage containers easily and efficiently. Compose manages multiple Docker containers through a configuration file. In the configuration file, all containers are defined through services and then started using the docker-compose script. , stop and restart the application, the services in the application, and all containers that depend on the service. Using one command, you can create and start all services from the YML file configuration, which is very suitable for scenarios where multiple containers are combined for development.
Docker-Compose and Docker compatibility
##Dcoker-Compose installation
1. Run the following command to download Docker Composecurl -L "https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-composeIf github access is too slow, you can use daocloud to download
curl -L "https://get.daocloud.io/docker/compose/releases/download/v2.2.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose2. Add docker-compose Read and write execution permissions
chmod -R 777 /usr/local/bin/docker-compose3. Check whether docker-compose is installed successfully

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。

容器管理ui工具有:1、Portainer,是一个轻量级的基于Web的Docker管理GUI;2、Kitematic,是一个GUI工具,可以更快速、更简单的运行容器;3、LazyDocker,基于终端的一个可视化查询工具;4、DockStation,一款桌面应用程序;5、Docker Desktop,能为Docker设置资源限制,比如内存,CPU,磁盘镜像大小;6、Docui。
