Launch MySQL Container With Docker Compose Now you can connect to the mysql client and run the source command or redirect the file to the mysql client. The first approach will be to copy the data from the local machine to the docker container using the " docker cp" command. INSERT INTO players VALUES ("E Hazard",30,"MADRID","Belgium") INSERT INTO players VALUES ("Kane",28,"SPURS","England") INSERT INTO players VALUES ("Neymar",29,"PSG","Brazil") INSERT INTO players VALUES ("Ronaldo",36,"MANU","Portugal") INSERT INTO players VALUES ("Messi",34,"PSG","Argentina") I have a sample file named " load_data.sql" with the following queries in it.

There are a few ways you can load the data. The main objective of setting up mysql is to load some data and run queries against it. You can also create your own user and grant him privileges as required.
#Starting mysql database server mysqld docker mysql password#
Replace the password 'mysqlpassword' with your own password. mysql> ALTER USER IDENTIFIED BY 'mysqlpassword' You can reset the root password by running the following query. The automatically generated root password will be long and it is not something to be remembered. If you skip this step, then an error will be thrown as shown below. You have to set MYSQL_RANDOM_ROOT_PASSWORD=1 to generate the random password. MYSQL_RANDOM_ROOT_PASSWORD → random password will be generated when the container is started.

You have to set MYSQL_ALLOW_EMPTY_PASSWORD=1. MYSQL_ALLOW_EMPTY_PASSWORD → Blank or Null password will be set.MYSQL_ROOT_PASSWORD → Setup your own password using this environment variable.You have to set up mysql root user password using any one of the below parameters. If you omit the -d flag, then you will see the container startup logs in the terminal and you have to open a new terminal session to connect to the container. d → Will start and run the container in detached mode. If you wish to know more about docker volumes take a look at our detailed article on same. MySQL stores the data in /var/lib/mysql/ inside the container and here it is mapped to localhost directory /var/lib/docker/volumes/mysql_volume1/_data, so your data will be persistent. To create persistent storage, I have created volume named " mysql_volume". The default behavior of docker is it will not persist the data once the container is removed,so you will lose all your data. Run the following netstat command in your local machine to check if the mapped port is listening or not once the container is launched. It is not necessary for the host port to be 3306, it can be anything that is available to be used. MySQL will listen at port 3306 so we are mapping ports ( 3306 → 3306) from your host machine to the docker container. If you are not specifying this flag, docker will assign some randomly generated names. name → To give a name to your container. Let’s break down the above command and see what each flag does. Run the following command to spin up the MySQL docker container: $ docker run -name mysql -p 3306:3306 -v mysql_volume:/var/lib/mysql/ -d -e "MYSQL_ROOT_PASSWORD=temp123" mysql You can also skip this step and run the " docker run" command as shown in the next section which will pull the image if not available locally. Now the image is ready to spin up the container. Mysql latest b05128b000dd 12 days ago 516MB Sample output: REPOSITORY TAG IMAGE ID CREATED SIZE To check if the image is available locally, you can run the following command: $ docker images mysql Heads Up: It is not necessary to use the tag " latest", by default it will pull the latest image. Run the following command to pull the MySQL image from the docker hub to your machine. The important thing is you have to decide what version of MySQL you are going to run. Go to the Docker Hub to get the MySQL docker image. $ docker -versionĭocker version 20.10.11, build dea9396 $ docker-compose -versionĭocker-compose version 1.29.2, build unknown 2. You can run the following commands to check the docker and docker-compose versions you are running with.

You can also refer the official Docker documentation links given below to know how to setup Docker and Docker compose. If you have not installed docker and docker-compose, refer the following guides: Connect to MySQL Database Using MySQL Workbenchīefore spinning up the MySQL docker container, you need to have docker and docker-compose installed in your machine.
