To remotely connect Docker containers using the SSH service based on CentOS

Environment: Host CENTOS7, directly search Docker's CentOS image, download the latest version

1, first according to Docker:yum Install-y Epel-release

Yum Install-y Docker

2, start the Docker:systemctl start Docker.service

3. Use PS to see if Docker is started

PS aux |grep Docker

4. Download the Docker image of CentOS

Docker pull CentOS Download latest version

There are no other services or tools in the mirror, except for the underlying CentOS system

5. Start the CentOS container

Docker run-it--name=centos-ssh Centos/bin/bash

6. Enter into the container to upgrade and install the SSH component

Yum-y Update

Yum-y Install Openssh-server

7, edit the sshd configuration file/etc/ssh/sshd_config, the US person Pam parameter set to 0

8. Generate a key pair in the host, copy the generated public key file contents into the container's/root/.ssh/authorized_keys

If not, create.

ssh-keygen-t RSA Direct Carriage return, view public key contents, and copy into the container

Cat/root/.ssh/id_rsa.pub

9. Set the container root password

echo "root:123456" |chpasswd

10. Start the sshd service and exit the container

/usr/sbin/sshd-d

Exit

11. Generate a new CentOS image that supports SSH

First look at the container Docker ps-a

12. Run the image and start the sshd service

Docker Run-p 10022:22-d sshd-centos/usr/sbin/sshd-d

Description: 10022 is the host's and container's communication port, outside the window (LAN) by accessing the address

SSH [email protected] Host IP 10022 (there is a space between the IP and the port, not:) will be able to enter the container
