If you want to run a docker container with a certain image and a specified command, you can do it in this fashion: docker run -it -d -name container_name image_name bash I’ll explain in detail what the above two commands do and what is the -it option in the docker run and exec command. :~$ docker exec -it my_container bashīin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var Here’s an example where I create a new container with Ubuntu as the base image and then I enter the running Ubuntu container and run the ls command: :~$ docker run -it -d -name my_container ubuntu bashħe77640bca686108ad415318278a1fa148e1c84d3b180276e19ec2b970ba9b67 You can create and run a container with the following command: docker run -it -d -name container_name image_name bashĪnd then, if you want to enter the container (to run commands inside the container interactively), you can use the docker exec command: docker exec -it container_ID_or_name /bin/bash
DOCKER RUN IMAGE SHELL HOW TO
ip netns exec xxxx netstat -antp|grep 8080.So, if you are new to Docker, you might wonder how to run a docker container. And of course, any other commands are valid, i.e. xxxx is always the same value received from the first command.
Now you may execute ip netns exec xxxx ip addr show to explore network world in container.The directory may not exist, do mkdir /var/run/netns first. Then ln -s /var/run/docker/netns/xxxx /var/run/netns/xxxx.This command will get reply like /var/run/docker/netns/xxxx.
DOCKER RUN IMAGE SHELL INSTALL
Useradd -create-home -shell /bin/bash -groups sudo username # includes 'sudo'Īpt-get install x11-apps # X11 demo applications (optional) Here are the commands that you would run inside the container to set it up. It takes a few steps, but it can be done. Let's say, for reasons that are your own, you really do want to use SSH. Some translation of the installation process will be required for non-Debian containers. Note: The below answer is based on Ubuntu (of 2016). Historical note: At the time I wrote this answer, the title of the question was: "How to ssh into a docker container?"Īs other answers have demonstrated, it is common to execute and interact with preinstalled commands (including shells) in a locally-accessible running container using docker exec, rather than SSH: docker exec -it (container) (command) Similarly, I could start a shell in the container $ docker exec -it web sh I could accomplish the same thing by running: $ docker exec -it d2d4a89aaee9 ip addr
E.g., given: $ docker psĭ2d4a89aaee9 larsks/mini-httpd "mini_httpd -d /cont 7 days ago Up 7 days webġ: lo: mtu 65536 qdisc noqueue state UNKNOWN It doesn't matter whether or not you're using docker compose just run docker ps and use either the ID (a hexadecimal string displayed in the first column) or the name (displayed in the final column). In the above command is the name or ID of the target container. Of course, whatever command you are running must exist in the container filesystem.
The docker exec command is probably what you are looking for this will let you run arbitrary commands inside an existing container. If your container is running a webserver, for example, docker attach will probably connect you to the stdout of the web server process. Docker attach will let you connect to your Docker container, but this isn't really the same thing as ssh.
