How to deploy MySQL using Docker

First we will run tutum-docker-mysql.

If you do not have an image of tutum/mysql locally, docker will download its image first, and this step may take some time. Wait until the execution is completed Let's check it and it should look like the following

##tutum-docker-mysql will automatically help us create a random password for us to access, which can be viewed through the log.

We log in to mysql through the password in the log

Theoretically, we can successfully log in to mysql at this time. You can create a library, a table, and then exit. .But when the container is stopped and restarted, your data will be lost. How to make your data really saved?

The solution is: mount a local file to the container (mount a local folder from the host on the container to store the database files).

First we stop the previous container

We specify a path that can be mounted locally and restart tutum-docker- mysql. We specify /home/walter/softwares/tutum-docker-mysql/data to hang to the /var/lib/mysql directory in the container (-v bind mount a volume). In this way, we can persist the data on the host (host) directory.

We specified the creation password as mypass when we started it above. Now we log in to mysql to create some data and see if it will be saved

Exit mysql and restart the container. The operations we have done will be retained. Every time we start this mysql, we can use the following command
