First make sure you have postgresql-client installed:
sudo apt-get install postgresql-client
Next, you need to find the IP address of the Docker container running PostgreSQL. You can do this by running the following command:
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container_name>
Once you have the IP address, you can connect to the PostgreSQL instance using the psql
command. Run the following command in your terminal:
psql -h <ip_address> -U <username> -d <database_name>
