问题 I have followed the instruction in https://registry.hub.docker.com/_/mysql/ to pull an image and running a container in which it runs a MySQL server. The container is running in the background and I would like to run some commands. Which is the best way to connect to the container and execute this command from command line? Thanks. 回答1: You can connect to your mysql container and run your commands using: docker exec -it mysql bash -l (Where mysql is the name you gave the container) Keep in

问题 I'm trying to understand the Docker world a little better, and can't quite seem to wrap my brain around the differences between these. I believe that OCF is an emerging container standard being endorsed by OpenContainers, and I believe that Docker is set to be the first reference implementation of that standard. But even then, I have concerns that the Google Gods don't seem to be providing answers for: What exactly is the OCF "standard"? Just a written document? A written API? A compiled C

问题 From what I read it seems that Docker-Compose is a tool to create multiple containers on a single host while Docker Swarm is a tool that can do the exact same thing but with more control and on multiple hosts with the help of Docker Stack. I went through the tutorial and also came across this thread: docker-compose.yml vs docker-stack.yml what difference? And I'm coming to the conclusion that there's no reason to ever use Docker-Compose when you can use Docker Swarm with Docker Stack. They

问题 I'm not sure if I've misunderstood something here, but it seems like it's only possible to set port mappings by creating a new container from an image. Is there a way to assign a port mapping to an existing Docker container? 回答1: You can change the port mapping by directly editing the hostconfig.json file at /var/lib/docker/containers/[hash_of_the_container]/hostconfig.json You can determine the [hash_of_the_container] via the docker inspect <container_name> command and the value of the "Id"

问题 I want to SSH to my containers created in an Azure App Service. These are Linux based containers and used Docker Compose to deploy these to Azure App Service. I have followed the article to enable SSH. For one of the container (Container A) I am able to SSH (exposed port 2222, 80 for this). But I would like to SSH to other containers (Container B) too. I have exposed another port 2223 for Container B and followed the same steps in that document. When I try to access them using the command ssh

问题 The problem description I have a Docker image, which is being executed with volume mounting options a large number of times. It is built in a way so that the default user does not have root permissions. However I need to make sure that when I mount the volume it is being mounted as root and not as the current working user because of security concerns. (The current working non-root user must not be allowed to delete any files inside the mounted volume.) Example From the host machine: docker

问题 Background I had build a npm server(sinopia) docker image(https://github.com/feuyeux/docker-atue/blob/master/docker-images/feuyeux_sinopia.md), and in the CMD line, it will run the start.sh every time when the container is generated. CMD ["/opt/sinopia/start.sh"] This shell will create a yaml file dynamically. sed -e 's/\#listen\: localhost/listen\: 0.0.0.0/' -e 's/allow_publish\: admin/allow_publish\: all/' /tmp/config.yaml > /opt/sinopia/config.yaml Question I wish I could edit this config
