Many developers still install a database on their computer and work on it.
It may be a preferable method, but using Docker takes only seconds to set up a database. I used PostgreSQL and Docker in my latest project. As a result, I have achieved efficiency and convenience. I will give you my experience with PostgreSQL and Docker.
I can start with finding the Docker image we will use. There are two easy ways to do this. I prefer to visit the Docker Hub website. Alternatively, it can be used the command below. It will list you similar results to the Docker Hub.
docker search postgresql
I will use the postgres, the official image can be obtained in the search results. I prepared a Docker command with important and necessary parameters. It can be easily customized and used this command.
docker run --name postgresqldb -e POSTGRES_USER=myusername -e POSTGRES_PASSWORD=mypassword -p 5432:5432 -v /data:/var/lib/postgresql/data -d postgres
It looks a little confused, but don't worry. I will explain these parameters.
Let's run the command together and see the result.
If you have encountered a similar output, you can be sure that everything is fine. You can see the working Docker containers by running the command below.
You can also stop or restart your container using start and stop commands. In this example I set the container name as postgresqldb. You can run the start and stop commands with your own chosen name.
docker start postgresqldb docker stop postgresqldb
You may think it took a long time because I explained the details. Don't be biased, you can create a PostgreSQL database just by running a single Docker command.
