This article mainly introduces what Docker-related commands are, which can be used for reference. Interested friends can refer to them. I hope you will gain a lot after reading this article.

Docker command

1. Command format:

Docker run-it-- name mydocker1 [image1] bash # individually named image1 as mydocker1

Docker run-it-- link mydocker1:mydocker1 [image2] bash connects two image so that image1 and image2 can communicate with each other

2. Command function:

Connect two container to communicate with each other

3. Command parameters:

-it-- name first name the first image1

-it-- link connects to the first image and can communicate with each other

4. Command example:

First open a window and enter the following command to open a docker window 1

[root@docker] # docker run-it-- name node1 node bash

Root@f2765d5fd9c8:/#

Open another window 2 again and enter the following command:

[root@docker] # docker run-it-- link node1:node1 node bash

Root@e85d11098482:/#

Enter the following command under the second docker window:

Root@e85d11098482:/# ping node1 shows that the ip address of node1 is 172.16.0.16

PING node1 (172.17.0.16): 56 data bytes

64 bytes from 172.17.0.16: icmp_seq=0 ttl=64 time=0.110 ms

64 bytes from 172.17.0.16: icmp_seq=1 ttl=64 time=0.073 ms

64 bytes from 172.17.0.16: icmp_seq=2 ttl=64 time=0.075 ms

64 bytes from 172.17.0.16: icmp_seq=3 ttl=64 time=0.094 ms

Round-trip min/avg/max/stddev = 0.073 ms 0.088 ms 0.110 Compact

Enter the following command under the first docker window to see that the IP address of the window is the IP address of node1

Root@f2765d5fd9c8:/# ip addr

1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
