Install Mysql In Docker Container


Volumes: my-db: Great, now we can start our container. In your command line or terminal, cd into the directory where you made your docker-compose.yml and from there, run docker-compose up (this. SQL Server is originally released to Windows platform. Recently, Microsoft released the linux version. In this tutorial, we will use docker to install SQL Server for Linux. Thus, we can use it on Mac. Prerequisite 2.1 Docker Machine with Large Storage. The SQL Server container requires at least 3.25 GB of RAM and large storage.

At work, I often need to install a specific version of MySQL, MariaDB or percona to run some experiments, such as checking version differences or providing test instructions. This blog series explains how to use docker to install mysql, MariaDB, or percona. This article is the first, focusing on MySQL.

Install mysql in docker container code

The advantage of docker is that it is very easy to install the latest version of MySQL and any other version, but it often does not match a typical production installation. Docker is really convenient when you need a simple single instance. If you are looking at some replication related behavior, it may not be appropriate.

These instructions are in the case of running test cases quickly and easily. Not applicable for production deployment. The following assumes that docker is installed.

First, you should know that there are only two “official” MySQL docker repositories. One of them is maintained by the docker team through a simple docker command mysql:latest It works. The other is maintained by Oracle’s MySQL team

Note: the latest in the syntax is the tag value, indicating the latest version in the default installation library

In the following example, we will use the docker image of the MySQL team, although the docker team works in a similar way.


Using docker to install the latest version of MySQL

This will launch the latest version of MySQL instance, which can be accessed remotely from anywhere using the specified root password. It’s easy to test, but it’s not a good security habit (that’s why it’s not the default).

Connect to the MySQL server docker container

Using docker installation means that you cannot get any tools, utilities, or libraries directly on the host, so you can install them separately, access the created instance from a remote host, or use the command line that comes with the docker image.

Start the MySQL command line client through docker

Use docker to start MySQL shell:

Managing MySQL server in docker container

When you want to stop the MySQL server docker container from running:

If you want to restart a stopped MySQL docker container, you should not attempt to restart it using docker run. Instead, you should use:

If an error occurs, for example, if the container is not started, you can access its log using the following command:

If you want to recreate a new docker container from scratch, you can run:

And then do it again docker runCommand.

Pass command line options to the MySQL server in the docker container

If you want to pass some command line options to MySQL server, you can do this in the following ways:

Running the specified version of MySQL server in docker

If you want to run a certain version of MySQL in the docker container, this is simple. You can use docker image tag to select the version you want and change the name to a different name to avoid name conflicts:

This will start MySQL 8.0.17 in the docker container.

This will launch the latest MySQL 5.7 in docker.

Running multiple versions of MySQL server in docker

At the same time, when running multiple versions of MySQL in docker, the potential problem is TCP port conflict. If you do not access the docker container from outside and only run programs contained in the same container, you can remove the port mapping (- P option), and then you can run multiple containers:

In more common cases, when you need to access the docker container from outside, you will need to map it to use a different external port name. For example, to start the latest MySQL 8 on ports 3306 / 33060 and MySQL 8.0.17 at 3307 / 33070, we can use:

If you want to use MySQL for more complicated things on docker, there are many things to consider.

In this article, we'll run a Camunda bpm platform connecting to MySQL Database in the Docker container. We'll use the MySQL client to verify the Camunda database.

In this article, we are going to run a Camunda bpm platform connecting to MySQL Database within the Docker container. At the same time, we'll use the MySQL client (workbench) to verify the Camunda database (Although the same can be done by Docker CLI for MySQL as well).

Below is the list of packages that you need to add before proceeding:

a) Download and install Docker-desktop

b) Download and install MySQL workbench (Optional, To verify the installation of MySQL in docker)

STEP-1:Running MySQL in Docker container

Run the below command in command prompt to run MySQL in Docker Container with name 'mysql'.

docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=mysqladmin -d mysql/mysql-server:latest

Install Mysql In Docker Container

Note: Set up your own password for MySQL instead of mysqladmin in the above command.

Open the Docker desktop app and verify MYSQL is running on the docker container.

STEP-2:Connecting MySQL Workbench with Docker container

a) Open CLI command prompt of mysql as highlighted.

b) Enter command mysql -u root -p press enter and enter the password as mysqladmin (OR as given in step-1). You will be connected to mysql console.


Note: On this console, also we can validate the Camunda database later using mysql commands hence steps 2-c, 2-d and 2-e are completely optional.

c) To connect MySQL with the workbench need to execute the below command on the MySQL console.

update mysql.user set host = '%' where user='root';

d) Open MySQL workbench and enter the details as below. Use password as provided in step-1.

e) Connect to MySQL Database.

f) Create a new schema in MySQL say named 'mydb' using the below command.

create database mydb;

g) Verify the database is created and having no tables.

Step-3: Running Camunda BPM

a) Open command prompt and execute the below command to start Camunda in docker container name as 'camunda-mysql-env '.

docker run -d --name camunda-mysql-env -p 8080:8080 --link mysql:db -e DB_DRIVER=com.mysql.cj.jdbc.Driver -e DB_URL=jdbc:mysql://db:3306/mydb?autoReconnect=true -e DB_USERNAME=root -e DB_PASSWORD=mysqladmin -e WAIT_FOR=db:3306 camunda/camunda-bpm-platform:latest

Install Mysql In Docker Container List

b) Refresh the database and check for Camunda tables are created inside 'mydb' database. The same can be verified in Docker CLI (for MySQL) also.

The same can be verified using CLI as well.

c) Open the browser and check if the Camunda application is running at http://localhost:8080/camunda/.
