This article mainly introduces "how the Linux host uses ssh to log in to the docker container". In the daily operation, I believe that many people have doubts about how the Linux host uses ssh to log in to the docker container. The editor has consulted all kinds of materials and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "how to log in to the docker container with ssh in the Linux host". Next, please follow the editor to study!

Host: XUbuntu 15.04 + docker

Enter the terminal, sudo-I, switch root, and enter docker-d

Open another terminal, switch root, and type docker search ubuntu. The result is as follows:

Enter docker pull ubuntu and the system will download the image from the first one.

After the download is complete, you can enter docker images to check whether the image has been downloaded to the local image.

Start a ubuntu container and enter bash,docker run-it ubuntu / bin/bash

At this point, you should see root@bc6a0a7912b1:/#, which proves that the container has been started successfully and entered the bash of the container.

Change the root password of the container: passwd until you enter a new password, for example: 123456

Install vim,apt-get install vim-y

To install the openssh-server of the container, type apt-get install openssh-server-y

After successful installation, vim / etc/ssh/sshd_config, modify the following two configurations

PermitRootLogin yes

UsePAM no

Start the ssh service, service ssh start

Exit the container, type exit, and then type docker ps-a to view the ID of the container

Submit the container to a new image, such as ubuntu-ssh, enter the docker commit container ID ubuntu-ssh

Start the mirrored container and map an idle local port (for example, 10000) to port 22 of the container, and start the container's sshd docker run-d-p 10000 usr/sbin/sshd 22 ubuntu-ssh / usr/sbin/sshd-D.

Now open a new terminal and enter ssh root@127.0.0.1-p 10000. If the link is successful, you will be asked to enter the password. Enter the 123456 just now to enter the terminal of the container.

At this point, the study on "how the Linux host uses ssh to log in to the docker container" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
