Short Description
Image for an empty MySQL database instance for running QuotesAPI.
Full Description

Supported Tags

The available versions of cycprime/quotesapi_mysql are:

  • QuotesAPI_MySQL version 0.1.0 (tag: 0.1 as well as latest)


The Dockerfile and sample configurations are available at the GitHub repo cycprime/QuotesAPIMySQL.

To Use the quotesapi_mysql Image

To run the image in a container, do the following:

docker run --name <my_quoteapimysql_container_name> \
           --detach \
           --env-file ./env/runtime/<environment_file> \
           --volume <my_data_volume_name>:/var/lib/mysql \
           --publish <host port>:<container port> \

<my_quoteapimysql_container_name> is the name of the container running the cycprime/quotesapi_mysql image.

./env/runtime/<environment_file> is the file path and name of the file containing the environment variables required my MySQL container to run.

<my_data_volume_name> is the name of the data volume that holds the MySQL database data.

A sample command will resemble the following:

> docker run --name test_container_01 \
             --detach \
             --env-file ./env/runtime/default.env \
             --volume my_data_volume:/var/lib/mysql \
             --publish \

To see the process status:

> docker ps -a

To review the log of the container, do the following:

> docker logs test_container_01 

To access the container:

> docker exec -it test_container_01 /bin/bash

To stop the container:

> docker stop test_container_01

To delete the container:

> docker rm test_container_01

To list all Docker data volumes:

> docker volume ls

To inspect the data volume:

> docker volume inspect my_data_volume

For a full list of docker commands, please refer to Docker's documentation The Docker commands.

Database Root User Password and Environment Variables

When running an instance of the image, the image expects a root password to be passed in. This password can be passed in via an environment variable. Since there are quite a few of these environment variables one can specify, the command makes use of an environment variable file, instead of enumerating each environment variable individually. To specify one's own environment variable file, simply copy the sample from Samples/ default.env to the env/runtime/ directory:

> cp Samples/default.env env/runtime/default.env

and modify the file env/runtime/default.env with your favourite text edit.

The full list of environment variables supported by MySQL is available at MySQL/MySQL-Docker. They can be added to the env/runtime/default.env file and adjusted accordingly.

By having these environment variables specified in the file instead of enumerating them on the command line minimize the chance of passwords being readily accessible via ps command or command history.

Data Store

MySQL data is stored in /var/lib/mysql. To allow data to persist beyond the life cycle of the image container, the image has a mount point at /var/lib/mysql. You can specify your own named data volume and map it to /var/lib/mysql. This is done via the --volume <my_data_volume_name>:/var/lib/mysql option in the docker run command.

If this option is omitted, /var/lib/mysql will be mounted to an annoymous data volume in Docker. Whether it is a named data volume, or an annoymous data volume, the data will still persist even if the image container is deleted. To remove a data volume, use the docker volume rm command.

Adding Network

To create a network for the container:

> docker network create --driver bridge quotesapi-db-network

To connect the container to the quotesapi-db-network:

> docker network connect quotesapi-db-network test_container_01

To check out the details on a network:

> docker network inspect quotesapi-db-network 

To disconnect a container from a network:

> docker network disconnect quotesapi-db-network test_container_01

To remove a network

> docker network  rm quotesapi-db-network
