In this article, you will learn how to do Postgres seeding using Docker Compose.
Let’s Start Creating Docker Seeding
Hope you are familiar with “Docker-Compose”
├── docker-compose.yml (File)
├── docker_postgres_init.sql (File)
Create a new file docker-compose.yml
Above file, we have created a Postgres Docker container with Port No: 5432
As well as set environment variables such as default username, password of Postgres container.
if you check the entire file we have also created volumes that point to the `docker_postgres_init.sql` file.
- ./docker_postgres_init.sql:/docker-entrypoint initdb.d/docker_postgres_init.sql
The script inside “docker_postgres_init.sql” will create a new table student and insert the records as well
When you run the following command in the root directory for the project.
then you will see in the console docker_postgres_init.sql script will be executed as the following screenshot
that means your script executed successfully.
How to test
For testing, we used Pgadmin4 configured already in the docker-compose file.
Try to run the following URL in the browser
and enter username and password as the following screenshot.
after successful login, you will see the following screen.
Then click on to server -> create -> server
You will see the following pop up then in the General tab type
Then click on the Connection tab as the following screenshot then input Hostname
You can get Hostname by typing the following command
$ ifconfig |grep inet
then click on to Save Button
then you will see the connection successful on the left side of the Pgadmin 4 navigation as shown below.
then go to Databases->root->Schema->Tables->students you will see there are 3 records as shown below in the screenshot.
