docker related instructions

1. View docker images:
   docker images can view all docker images in the current server
   docker images | grep wu can use pipelines to filter images containing wu

2. Docker operation:
   docker run -it -v /mnt/storage00/wusiyu:/workspace/storage00/wusiyu hub.bilibili.co/wusiyu/torch:latest run an image, so as to run a container
   –name xxx, you can name the
   container- it, an interactive terminal, requires a terminal when running the container
   -v The actual physical address of the server file: the file address mapped in docker (the code in docker will not be bound to the server if v is not added) /bin/bash
   , Start the container from the command line

3. Common use of docker:
   shortly exit ctrl+p+q
   and enter docker again attach wusiyu1 (container name)
   After modification, you need to commit to save docker
   docker commit wusiyu1 hub.bilibili.co/wusiyu/torch:latest
   After commit, you need to push to dockerhub The link in the platform is successful
   docker push hub.bilibili.co/wusiyu/torch:latest
   Note: If the push fails, it may be because there is no login
   Login method: docker login hub.bilibili.co -u wusiyu and then enter the password
   docker ps: View current The running container
   docker commit container name image name: tag: save the container as an image, and store the changes to the dependent environment during the running of the container docker
   logs docker
   attach container name: re-enter the container
   docker push image name: tag: put the image Upload to dockerhub

4. docker temporarily exit the terminal and enter the container again
   docker exec -it wusiyu1 /bin/bash
   

5. After entering, view the record
   docker logs wusiyu1 | tail -n 500
   (the latest 500 lines)
