Docker is an open platform enabling developers and sysadmins to build, ship, and run distributed applications across various environments, utilizing core technologies like LXC and AUFS. The document covers Docker's architecture, commands for managing images and containers, and the benefits of using Docker Compose for multi-container applications compared to traditional VM setups. It also discusses resource consumption and provides usage examples for different roles within a development workflow.
Docker at the gate
- 1. Docker at the gate [email protected] Lean session in 30 min S02
- 2. What is Docker Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications, whether on laptops,data center VMs, or the cloud. 核心技术=LXC + AUFS
- 3. How LXC works Kernel namespaces (ipc, uts, mount, pid, network and user) Apparmor and SELinux profiles Seccomp policies Chroots (using pivot_root) Kernel capabilities CGroups (control groups)
- 4. Docker vs Traditional VM
- 5. What is AUFS
- 6. Image, container and registry Image <-> Container 公库，镜像库和私库 repo.bigdata.360es.cn/library/Jenkins sonarqube:alpine
- 7. 主要命令和生命周期
- 9. 其他命令 docker rm 删除镜像 docker logs 打印控制台输出 docker inspect 查看容器详情 docker attach 连接到容器内的控制台 docker stats 资源消耗
- 10. 重要参数 -v 挂载 --name 容器名称 --network 网络 -p 宿主机端口映射 -it 交互模式 -d 后台模式 --rm stop之后自动移除 -e 设置环境变量
- 11. docker-compose Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application's services. Then, using a single command, you create and start all the services from your configuration. 人话版本：命令行太复杂了，把参数配置化，用来大规模应用的编排
- 12. 示例 --name --restart -e -p -v --network docker network create prom_network
- 14. local-dev-env https://git01.360es.cn/SNC/local-dev-env docker(docker-compose) + makefile 常用场景覆盖 测试人员：make all-up Agent工程师：make simulator-up ，make odl-up ODL工程师：make odl-dev-up Commander工程师：make infra-up，make odl-up，make odl-dev-up
