Docker - URL syntax [duplicate] - docker

Question

What is the format for the PostgreSQL connection string (URL postgres://...) when the host is not the localhost?

Answer 1

If you use Libpq binding for respective language, according to its documentation URI is formed as follows:
postgresql://[user[:password]#][netloc][:port][/dbname][?param1=value1&...]
Here are examples from same document
postgresql://
postgresql://localhost
postgresql://localhost:5432
postgresql://localhost/mydb
postgresql://user#localhost
postgresql://user:secret#localhost
postgresql://other#localhost/otherdb?connect_timeout=10&application_name=myapp
postgresql://localhost/mydb?user=other&password=secret

Answer 2

The following worked for me
const conString = "postgres://YourUserName:YourPassword#YourHostname:5432/YourDatabaseName";

Answer 3

DATABASE_URL=postgres://{user}:{password}#{hostname}:{port}/{database-name}

Answer 4

Here is the documentation for JDBC, the general URL is "jdbc:postgresql://host:port/database"
Chapter 3 here documents the ADO.NET connection string,
the general connection string is Server=host;Port=5432;User Id=username;Password=secret;Database=databasename;
PHP documentation us here, the general connection string is
host=hostname port=5432 dbname=databasename user=username password=secret
If you're using something else, you'll have to tell us.

Answer 5

the connection url for postgres
syntax:
"Server=host ipaddress;Port=5432;Database=dbname;User Id=userid;Password=password;
example:
"Server=192.168.1.163;Port=5432;Database=postgres;User Id=postgres;Password=root;

Answer 6

server.address=10.20.20.10
server.port=8080
database.user=username
database.password=password
spring.datasource.url=jdbc:postgresql://${server.address}/${server.port}?user=${database.user}&password=${database.password}

Answer 7

The connection string can also be retrieved programmatically from working DB connectors.
For instance I sometimes extract connection strings from SQLAlchemy's engine, like this:
> db_engine.url
postgres://{user}:{password}#{host}:{port}/{db_name}?sslmode=require

Answer 8

Some people seem to misread the database name as a server name and the host as a postgresql server? A host hosts a postgresql server that has a database. Or am I missing something.
postgresql://my_host/&server=my_postgresql_server?user=my_user&port=my_port&password=my_password&database=my_database
Example:
my_host: can be "localhost" (but that is not in the question) or an ip address of a host.
postgresql://my_host/&server=postgres?user=postgres&port=5432&password=postgres&database=test_db
Worked for me in Python with sqlalchemy and a postgresql localhost running. Needs sqlalchemy, postgresql, and psycopg2 to get it to work.
PS: The question is about a postgres://... URL, but this would not work here. Instead, you need postgresql, and what is run in the end in Python is dialect+driver (see Database URLs) = postgresql+psycopg2, without having to write it like this.

Answer 9

The general format of database url
DATABASE_URL=postgresql://username:password#host:port/dtabase_name
If you are using postgresql sql with asyncpg the database url would be
DATABASE_URL=postgresql+asyncpg://username:password#host:port/dtabase_name
Remember to never push your database password so you should use your DATABASE_URL in .env file
The port is optional if you use the default one
Like this you can connect both local and remote database think of that once you want to check an issue that occur in the remote deployed versions
ex of localhost DATABASE_URL would be
DATABASE_URL=postgresql+asyncpg://postgres:dina#localhost/mysens
If you deployed your database on Heroku and you want to connect it with your local app, go to Heroku Postgres installed add-on go to settings and click on view credential in Database Credentials and use the uri to connect to your database
DATABASE_URL=postgresql+asyncpg://sqnalxxxxxxxxx:160xxxx2bdd2942b26c93c392xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx#ec2-35-173-91-114.compute-1.amazonaws.com:5432/del6o4cjoqfsov
