Docker
- 2. Docker ● Docker is written in Go and takes advantage of several features of the Linux kernel to deliver its functionality. ● Docker is an open platform for developing, shipping, and running applications ● Docker enables you to separate your applications from your infrastructure so you can deliver software quickly
- 3. Comparing Containers And Virtual Machines Image Container Repository
- 4. Comparing Containers And Virtual Machines 特性 容器 虛擬機器 硬碟使用 一般為 MB 一般為 GB 性能 接近原生 較差 系統支援量 單機支持上千個容器 一般機十個 隔離性 安全隔離 完全隔離 啟動進度 秒級 分鐘級
- 6. Docker - Repository ● Public Repository Docker Hub Docker Pool ● Private Repository
- 7. Docker - Repository 14.04 12.04 13.10 5.0 6.0 7.0 Ubuntu Repository CentOS Repository Repository Server
- 8. Search image > docker search mysql
- 9. Pull image from Repository > docker pull ubuntu:12.04
- 10. View image information > docker images
- 11. Create container > docker create ubuntu Output :79474d40eec0853…...de705a8c5f87673dfa2e6d6e5f
- 12. Create and run container > docker run ubuntu:14.04 /bin/echo “Hello world” Output : Hello world
- 13. What happens when you run a container 1. Pulls the ubuntu image 2. Creates a new container 3. Allocates a filesystem and mounts a read-write layer: 4. Allocates a network / bridge interface 5. Sets up an IP address 6. Executes a process that you specify 7. Captures and provides application output
- 14. Create and run container > docker run -ti ubuntu /bin/bash > root@af8bae53bdd3:/# pwd
- 15. List containers > docker ps -a
- 16. Building an image from a Dockerfile ● 基礎映像檔資訊 ● 維護者資訊 ● 映像檔操作指令 ● 容器啟動時需執行
- 17. Dockerfile ● Here is the format of the Dockerfile: INSTRUCTION arguments ● The instruction is not case-sensitive ● Convention is for them to be UPPERCASE to distinguish them from arguments more easily.
- 18. Dockerfile Dockerfile: #基礎映像檔資訊 FROM ubuntu:14.04 #維護者資訊 MAINTAINER Jason <[email protected]> #映像檔操作指令 RUN apt-get update && apt-get install -y ruby ruby-dev RUN gem install sinatra #容器啟動時需執行 CMD command param1
- 19. Dockerfile ● ADD <src>... <dest> ● COPY <src>... <dest> ● ENTRYPOINT ["/bin/echo"] ● CMD ["/bin/echo", "this is a echo test"] ● WORKDIR /a ● EXPOSE 5990 ● Volume /myVol
- 20. Build Dockerfile > docker build -t abc/ub /docker_builder/
- 21. Create a new image from a container's changes > docker commit -m "Add file" -a "jason" 0b2616b ubuntu/jason:v2 Output: sha256:7030a919c…..109a5c3074d3971ddaa4ca2ce20f
- 22. Delete container and image ● Delete a container > docker rm [Container ID] ● Delete a image > docker rmi [Container ID]
- 23. Other command docker inspect [container ID] docker logs [container ID] docker start [container ID] docker stop [container ID] docker attach [container ID] docker run -d ubuntu:14.04 docker run -P ubuntu:14.04 docker run -p 27019:27017 mongo
