After the install is complete you will have to log out and back in. Head to this link and click the Get Docker link to download the installer.
#Running postgres in docker full#
In the end, I decided to try and run the Postgres process using Docker instead installing directly on Windows or dealing with a full VM. This kicked off a lot of searching on my part and didn’t find a good definitive answer on why that is or isn’t the way to do. This is the route I was going to at first, but in Rob’s book, he suggests using a VM for Postgres installation on Windows.
On the download section of the official Postgres site, there is an option to download an installer. For personal projects SQL Server’s cost and be prohibitive and the release of Rob’s book added up to a good time to give PostgreSQL a try. I have a lot of experience using Microsoft’s SQL Server, but up until now, I haven’t touched PostgreSQL.
Giving the file names numeric ascending value helps in controlling the execution order.Over the weekend I finally got the chance to start reading A Curious Moon by Rob Conery which is a book on learning PostgreSQL by following the fictional Dee Yan as she is thrown into database administrator role at an aerospace startup. I have two simple SQL script files as follows:Īnd here are the content of these script files, feel free to adjust as per your requirements: Notice the Copy command which is copying the script files from host directory to container. Let's create a docker file to structure our setup requirements. You can run the above-mentioned commands individually, but typically, you will create a docker file to build an image. >docker exec -it pg-docker psql -U postgres -f /opt/scripts/test_script.sql Docker File We can also run sql-script in a similar manner as shown below: >docker exec -it pg-docker psql -U postgres -c "CREATE DATABASE testdb " We can issue SQL commands via docker cli as follows: >docker exec -it pg-docker psql -U postgres We can also run psql inside the container by using the following command: Or u can use Azure Data Studio and make the connection as shown below: >psql -h localhost -U postgres -d postgres For example, to connect using psql we can execute
Once the container is up an running, connecting to it from an application is no different than connecting to a Postgres instance running outside a docker container. But if we want to persist data generated by the Postgres instance running inside a container beyond the container’s lifecycle, we need to map a local mount point as a data volume to an appropriate path inside the container. if you are running some database/integration testing and want to get rid of test data then it's great). The following command will pull down the latest stable release Postgres image from the official Postgres docker hub repository.Ĭontainer data is gone once it is stopped and this is useful for certain situations (e.g. I am assuming that you already have installed docker on your machine and it is running. Now the idea is that you are gonna get, I don’t know, lights up the old neurons and creates one of those aha moments. I will try to keep this post very simple and will not cover complex workflows (those will be covered in later posts) and this will keep the discussion focus and help in easy learning.

In this post, I will show you how to quickly get started with docker and PostgreSQL.
#Running postgres in docker software#
Docker is changing how we distribute and install software and it is a very popular tool in many areas of software development as well.
