This image will be deprecated soon. Please use the docker official image: https://hub.docker.com/_/mysql/
Base docker image to run a MySQL database server
Different versions are built from different folders. If you want to use MariaDB, please check our tutum/mariadb
image: https://github.com/tutumcloud/tutum-docker-mariadb
To create the image tutum/mysql
, execute the following command on the tutum-mysql folder:
docker build -t tutum/mysql 5.5/
To run the image and bind to port 3306:
docker run -d -p 3306:3306 tutum/mysql
The first time that you run your container, a new user admin
with all privileges
will be created in MySQL with a random password. To get the password, check the logs
of the container by running:
docker logs <CONTAINER_ID>
You will see an output like the following:
========================================================================
You can now connect to this MySQL Server using:
mysql -uadmin -p47nnf4FweaKu -h<host> -P<port>
Please remember to change the above password as soon as possible!
MySQL user 'root' has no password but only allows local connections.
========================================================================
In this case, 47nnf4FweaKu
is the password allocated to the admin
user.
Remember that the root
user has no password, but it's only accessible from within the container.
You can now test your deployment:
mysql -uadmin -p
Done!
To pass additional settings to mysqld
, you can use environment variable EXTRA_OPTS
.
For example, to run mysql using lower case table name, you can do:
docker run -d -p 3306:3306 -e EXTRA_OPTS="--lower_case_table_names=1" tutum/mysql
If you want to use a preset password instead of a random generated one, you can
set the environment variable MYSQL_PASS
to your specific password when running the container:
docker run -d -p 3306:3306 -e MYSQL_PASS="mypass" tutum/mysql
You can now test your deployment:
mysql -uadmin -p"mypass"
The admin username can also be set via the MYSQL_USER
environment variable.
If you want a database to be created inside the container when you start it up
for the first time you can set the environment variable ON_CREATE_DB
to a string
that names the database.
docker run -d -p 3306:3306 -e ON_CREATE_DB="newdatabase" tutum/mysql
If this is combined with importing SQL files, those files will be imported into the created database.
In order to persist the database data, you can mount a local folder from the host on the container to store the database files. To do so:
docker run -d -v /path/in/host:/var/lib/mysql tutum/mysql /bin/bash -c "/usr/bin/mysql_install_db"
This will mount the local folder /path/in/host
inside the docker in /var/lib/mysql
(where MySQL will store the database files by default). mysql_install_db
creates the initial database structure.
Remember that this will mean that your host must have /path/in/host
available when you run your docker image!
After this you can start your MySQL image, but this time using /path/in/host
as the database folder:
docker run -d -p 3306:3306 -v /path/in/host:/var/lib/mysql tutum/mysql
Another way to persist the database data is to store database files in another container. To do so, first create a container that holds database files:
docker run -d -v /var/lib/mysql --name db_vol -p 22:22 tutum/ubuntu-trusty
This will create a new ssh-enabled container and use its folder /var/lib/mysql
to store MySQL database files.
You can specify any name of the container by using --name
option, which will be used in next step.
After this you can start your MySQL image using volumes in the container created above (put the name of container in --volumes-from
)
docker run -d --volumes-from db_vol -p 3306:3306 tutum/mysql
In order to migrate your current MySQL server, perform the following commands from your current server:
To dump your databases structure:
mysqldump -u<user> -p --opt -d -B <database name(s)> > /tmp/dbserver_schema.sql
To dump your database data:
mysqldump -u<user> -p --quick --single-transaction -t -n -B <database name(s)> > /tmp/dbserver_data.sql
To import a SQL backup which is stored for example in the folder /tmp
in the host, run the following:
sudo docker run -d -v /tmp:/tmp tutum/mysql /bin/bash -c "/import_sql.sh <user> <pass> /tmp/<dump.sql>"
Also, you can start the new database initializing it with the SQL file:
sudo docker run -d -v /path/in/host:/var/lib/mysql -e STARTUP_SQL="/tmp/<dump.sql>" tutum/mysql
Where <user>
and <pass>
are the database username and password set earlier and <dump.sql>
is the name of the SQL file to be imported.
To use MySQL replication, please set environment variable REPLICATION_MASTER
/REPLICATION_SLAVE
to true
. Also, on master side, you may want to specify REPLICATION_USER
and REPLICATION_PASS
for the account to perform replication, the default value is replica:replica
Examples:
-
Master MySQL
-
docker run -d -e REPLICATION_MASTER=true -e REPLICATION_PASS=mypass -p 3306:3306 --name mysql tutum/mysql
-
Example on Slave MySQL:
-
docker run -d -e REPLICATION_SLAVE=true -p 3307:3306 --link mysql:mysql tutum/mysql
Now you can access port 3306
and 3307
for the master/slave MySQL.
MYSQL_USER
: Set a specific username for the admin account (default 'admin').
MYSQL_PASS
: Set a specific password for the admin account.
STARTUP_SQL
: Defines one or more SQL scripts separated by spaces to initialize the database. Note that the scripts must be inside the container, so you may need to mount them.
- Volume created by MySQL 5.6 cannot be used in MySQL 5.5 Images or MariaDB images.
