This article introduces the knowledge of "how to create an image and a container in Docker". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Create a mirror

1. Here is a handwritten Dockerfile document

2. Transfer the Dockerfile file to / usr/redis

3. Then you need to customize the network type

Since the default network cannot set a fixed address, we will create a custom network and specify the network segment: 172.10.0.01and16

Docker network create-subnet=172.10.0.0/16 mynetwork

Delete Custom Network

Docker network rm mynetwork is fine.

If you can't remember the command, then use docker network help directly.

4. Create an image

Docker build-t redis1.

Pay attention to a dot in the back.

5. View the created image

Docker images

Create a container

1. Create a container

Docker run-itd-- name redis-kaka-p 6384 name redis-kaka 6379-ip 127.10.0.4 redis1

Parameter explanation:

Redis-kaka: container name

Redis1: image name

-d: runs the container in the background and returns the container ID

-I: runs the container in interactive mode, usually in conjunction with-t

-p: Port mapping, format: host (host) port: container port

-t: reassign a pseudo-input terminal to the container, usually used in conjunction with-I

-- ip: make a fixed ip for the container

-- net: specifies the network mode

2. View the container

Docker ps-a\ docker container ls

3. Enter the container

Docker exec-it redis-kaka bash
