How to install Postgresql in docker

I use Docker Desktop

prerequisites

1. Docker desktop run already. ( test docker at Powershell input docker ps )

Contrainer is show ( docker run already )

step to install postgresql

1. Pull postgres repository to docker images

docker pull postgres

2. check images

input docker images at powershell

3. run images with username password and database

docker run — name psqldb -e POSTGRES_USER=admindb -e POSTGRES_PASSWORD=11111111 -e POSTGRES_DB=temp1 -p 5432:5432 -d postgres

name => contrainer name

• e -> parameter
• POSTGRES_USER = username
• POSTGRES_PASSWORD = password
• POSTGRES_DB = db for user access
• -p = port out: port in
• -d run deamon
• postgres at last = images name

4. check connection ( I use Azure data studio )

5. connect success
