Using Third Party Images: Databases
Running your database in a Docker container can help streamline your development process and ease deployment. Docker Hub provides numerous pre-made images for popular databases such as MySQL, PostgreSQL, and MongoDB.
Example: Using MySQL Image
To use a MySQL database, search for the official image on Docker Hub:
docker search mysql
Find the official image, and pull it:
docker pull mysql
Now, you can run a MySQL container. Specify the required environment variables, such as MYSQL_ROOT_PASSWORD, and optionally map the container’s port to your host machine:
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -p 3306:3306 -d mysql
This command creates a new container named some-mysql, sets the root password to my-secret-pw, and maps port 3306 on the host to port 3306 on the container.
Example: Using PostgreSQL Image
For PostgreSQL, follow similar steps to those outlined above. First, search for the official image:
docker search postgres
Pull the image:
docker pull postgres
Run a PostgreSQL container, specifying environment variables such as POSTGRES_PASSWORD:
docker run --name some-postgres -e POSTGRES_PASSWORD=my-secret-pw -p 5432:5432 -d postgres
Example: Using MongoDB Image
Running a MongoDB container with Docker follows a similar pattern as previous examples. Search for the official image:
docker search mongo
Pull the image:
docker pull mongo
Run a MongoDB container:
docker run --name some-mongo -p 27017:27017 -d mongo
