Docker The latest ultra detailed tutorial ——Docker Create run MySQL And mount

（1） Pull mysql Mirror image

First of all, we need to Docker Get on the mysql Mirror image , Just go first DockerHub Official website pull One down , Here we choose mysql:8.0.29

docker pull mysql:8.0.29

MySQL Large image , therefore pull Of It took a long time , Please be patient ！

In order not to pull again next time , It can be Backup （save） Go to the local （ Review the orders ！）

docker save -o mysql8.0.29.tar mysql:8.0.29

notes ：-o  Is to specify the file path of the output  

If you need it next time , You don't have to go DockerHub On pull 了 , Directly from the local load Just fine ！ 

sudo docker load -i mysql8.0.29.tar

notes ：-i Indicates the file name to upload

Here are my Local temporal DockerRepository Warehouse ！ 

（2） Create directory

We do not use data volume mount , Here, the directory is directly mounted （ Specify your own directory ！）

Containers can not only mount data volumes , You can also mount directly to the host directory . The relationship is as follows ：

• With data volume mode ： Host directory --> Data volume ---> In-container directory （ We I don't know the catalogue Where is the , You need to go to the official website to find ）

• Direct mount mode ： Host directory ---> In-container directory （ We created our own directory , I know ！ Easy to modify later 、 maintain ）

mkdir /tmp/mysql/data
mkdir /tmp/mysql/conf

Then we will customize hmy.cnf  The configuration file is passed in ！ 

stay DockerHub Official website There are Provide corresponding information about cnf Explanation of the configuration file ： 

（3） function mysql Containers  

docker run \
    --name mysqlname \
    -e MYSQL_ROOT_PASSWORD=888888 \
    -p 3306:3306 \
    -v /tmp/mysql/conf/hmy.conf:/etc/mysql/conf.d/hmy.conf \
    -v /tmp/mysql/data:/var/lib/mysql \
    -d \
    mysql:8.0.29

The results are as follows ： 

There are many directories involved , stay DockerHub Its official website It gives a very specific explanation ！ 

Mysql - Official Image | Docker Hub

Customize MySQL The configuration file mysql-conf

Where the data is stored mysql-data

Use docker ps Check it out. ：

docker ps 

 

（4） Test database connection  

Up there we pass ps Command to see mysql Containers It's already running , But we need to confirm the visit further mysql Does the database OK. We can open it navicat Tools , Do the following ！

Successful connection , See if it can be opened  

Testing is completed ！
