So far, we've created a database and a table. "baedlungauthor_pkey" PRIMARY KEY, btree (author_id) Now we'll use the below command to get the schema detail of table baeldungauthor: psql -U baeldung -d baeldung -c "\d baedlungauthor"Ĭolumn | Type | Collation | Nullable | Default Public | baedlungauthor | table | baeldung Let's list out the created table in the database: psql -U baeldung -d baeldung -c "\d" The command to create a table is as follows: CREATE TABLE baeldungauthor ( $ createdb -h localhost -p 5432 -U baeldung baeldung In order to access the database, we have to set up a connection to the Postgres server using pgAdmin. We can easily access PostgreSQL databases using the pgAdmin GUI. In the above command, we provided the PGADMIN_DEFAULT_EMAIL and PGADMIN_DEFAULT_PASSWORD as an environment variable to the pgadmin-baeldung container: To demonstrate, let's run the container using the below command: $ docker run -name pgadmin-baeldung -p 5051:80 -e " " -e "PGADMIN_DEFAULT_PASSWORD=baeldung" -d dpage/pgadmin4 Status: Downloaded newer image for dpage/pgadmin4:latest To do this, we need to pull the pgAdmin image using the following command: $ docker pull dpage/pgadmin4:latestĭigest: sha256:f820e5579857a7210599f998c818777a2f6f39172b50fbeb2faaa1a70413e9ac To perform all the queries from the UI, we can use the pgAdmin. pgAdmin can be used to run SQL queries on PostgreSQL databases.
#Create root user postgresql mac install
Now we'll install pgAdmin, a web-based user interface tool used to manage PostgreSQL databases and services. So far, the PostgreSQL server is active and running on the 5432 port. To back up the data, we also mounted the /var/lib/postgresql/data directory to the /data directory of the host machine of the postgres container. We exposed the 5432 port on the host using the “-p 5432:5432” in the docker run command. By default, the PostgreSQL database runs on the 5432 port.
#Create root user postgresql mac password
The above command uses environment variables POSTGRES_USER and POSTGRES_PASSWORD to set the username and password for the PostgreSQL database. Now we'll run the Docker container using the postgres:latest image with the below command: $ docker run -itd -e POSTGRES_USER=baeldung -e POSTGRES_PASSWORD=baeldung -p 5432:5432 -v /data:/var/lib/postgresql/data -name postgresql postgresĥaeda2b20a708296d22db4451d0ca57e8d23acbfe337be0dc9b526a33b302cf5 Status: Downloaded newer image for postgres:14.2
We can also pull a particular version of the postgres image using the below command: $ docker pull postgres:14.2ĭigest: sha256:e3d8179786b8f16d066b313f381484a92efb175d1ce8355dc180fee1d5fa70ec
In the above command, we pulled the postgres latest stable image. Status: Downloaded newer image for postgres:latest
To run a PostgreSQL using Docker, we first need to pull the postgres public image available on Docker Hub: $ docker pull postgresĭigest: sha256:ab0be6280ada8549f45e6662ab4f00b7f601886fcd55c5976565d4636d87c8b2
