How does a Redis container in Docker operate on a connection? 1. Login Putty has the following information:

Public virtual IP (VIP) address
42.159.156.115
Internal IP Address
10.205.178.22
IP Address for eth0:10.205.178.22
IP Address for docker0:172.17.42.1

2. Download http://download.redis.io/redis-stable/redis.conf Modify the following fields

# Requirepass foobared Get rid of comments, foobared change to their own password password

4. Running a mapped Redis

sudo docker run-t-i-p 172.17.42.1:6379:6379 Redis:latest/bin/bash

Note: The IP address here is Docker's IP address

5. Download the Conf file and run the Redis-server

Cd/usr/local/bin
Curl-o redis.conf https://fs10n2.sendspace.com/dl/03acafeeb8a1b799798666d55267a9cd/54a419057626bfac/p1j6ac/redis.conf
Note: If there are errors in parentheses, try more times if Meet:curl: (6) couldn ' t resolve host ' fs10n3.sendspace.com ')

Redis-server redis.conf

6. After starting the Redis-server, turn off the putty7. Re-enter Putty8. For testing convenience directly in the machine to install a redis-server:

Apt-get Install Redis-server

9. Enter the container and set the value:

sudo docker ps-l

Docker-enter 4fb1f04d706c

Redis-cli-a Password

Set MyValue Valueindocker

Press Ctrl+d to exit the Docker container

10. Redis-server in Docker on the native connection;

Redis-cli-h 172.17.42.1-a Password

Get myvalue

"Valueindocker"

11. Also on how the public network accesses Docker, is attempting to:

Iptables-t nat-a prerouting-m tcp-p tcp--dport 12345-j DNAT--to-destination 172.17.42.1:6379
Iptables-t nat-a postrouting-m tcp-p tcp--dport 12345-d 172.17.42.1-j SNAT--to-source 42.159.156.115
Iptables-a input-p TCP--dport 12345-j ACCEPT
