docker-container

问题 I have a bunch of Docker containers running on a server and I used the "latest" tag or no tag at all for all of them. Now I want to freeze the image versions, but I have no idea when I pulled these images, so I can't tell which version "latest" is referring to. docker ps is just showing me that the containers use the "latest" or no tag, like this: # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 371d6675888b node:latest "npm start" 6 days ago Up 2 hours project_xyz_1

问题 It may sound trivial but I couldn't find a easy way to copy multiple files into the root folder of a docker volume. I am using Ubuntu Xenial 16.04 and Docker 1.12.1 . For example if I have an Ubuntu container with the volume /my_data : docker run --name my_container -v /my_data -d ubuntu:latest In my host machine I have a folder called /tmp/my_data/ with multiple files inside, and I would like to copy all those files into the volume /my_data in my_container . I have tried the following

问题 I know, there is possible way how to copy file bidirectionally between host and docker container using docker cp and also it is possible to obtain file from running container using docker-py. But I am not able to figure out how (or if it is even possible) copy file from host to running container using docker-py. Do you guys have any experiences with such kind of problem? Is it possible to do or I have to execute command using python os.system . I would like to avoid this solution. 回答1:

问题 As the title reads, I'm trying to assign more memory to my container. I'm using an image from docker hub called "aallam/tomcat-mysql" in case that's relevant. When I start it normally without any special flags, there's a memory limit of 2GB (even though I read that memory is unbounded if not set) Here are my docker stats CONTAINER CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS ba57d6c9e9d2 0.22% 145.6 MiB / 1.952 GiB 7.29% 508 B / 508 B 0 B / 6.91 MB 68 I tried setting memory explicitly

问题 I have created a Docker container with a tomcat server. I have started the tomcat server and i can see the logs that tomcat server started successfully.
