Docker is becoming mainstreamline to package and deploy self sufficient application containers. It wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in. The same Linux kernel and libraries can be shared between multiple containers running on the host.
Please visit my blog previous blog Install Docker to setup docker.
Let’s Started
Docker hub provides images for all the software and tools. let’s find out the mysql docker image.
There are many MySQL Docker images available, but it is always better to go with the official release. As they are highy optimised, bug free and stable. You can download to your computer using pull command. After that we can list down the docker images.

Run MySQL Container
After an image has been downloaded, you may then run a container using the downloaded image with the run subcommand. If an image has not been downloaded when docker is executed with the run subcommand, the Docker client will first download the image, then run a container using it.

Looks good. Our MySQL Container is running now. As per the details from above logs.
Let’s verify the status of the container.
krishna@ubuntu:~$ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a2e44d353cbb mysql "docker-entrypoint..." 4 minutes ago Up 4 minutes 3306/tcp mysql_server krishna@ubuntu:~$
MySQL container is now running and accessible on port 3306 of that container. Use the following command to see what happened during the container startup:
krishna@ubuntu:~$ sudo docker logs mysql_server
Connecting to Container
Next, we retrieve the IP address of that container in order to access it. Run the inspect command:
krishna@ubuntu:~$ sudo docker inspect mysql_server

Another Access Method
Your command prompt should change to reflect the fact that you’re now working inside the container and should take this form
root@a2e44d353cbb:/#
Now you may run any command inside the container.

Conclusion
VOWW…. We now have a MySQL instance running in a container.
Docker allocates a dynamic IP address on every running container. Whenever a container is restarted, you will get a new IP address. You can get the IP address range from the Docker network interface in the Linux box. To sort this issue there is an option called –link
