![]() ![]() The output may vary depends on if we already downloaded the images and setup the volumes. To check if services are running successfully, we can use command: docker-compose ps.įigure 03: Example docker-compose ps outputĪfter running Docker Compose services, open web browser and go to localhost:15432. The port number is based on the mapping we configured under pgadmin service. Then key-in the email and password configured using the environment variable: PGADMIN_DEFAULT_EMAIL and PGADMIN_DEFAULT_PASSWORD.Įnter Name under General. The value can be anything.Įnter Host name/address, Username and Password under Connection. For Host name/address, the value is the Docker Compose database service name, in our case is postgres.For Username, the value is the environment variable POSTGRES_USER.For Password, the value is the environment variable POSTGRES_PASSWORD.Īnd click Save to finish create.Compose file version 3 reference docker.: Updated the guide with a more up-to-date method for sending a password along with the commands.Why and How To Use Docker for Development.To stop Docker Compose service, just execute command: docker-compose downįigure 09: Example docker-compose down output After done, we can get access to the database from the sidebar. I ran into this just today, and thought I'd share one method that I felt was easy, fast and served my purpose. Depending on why you need to dump/restore a database, this might help for you, too. Since you are not able to provide a password directly through arguments, we rely on the PGPASSWORD environment variable: docker exec -i pg_container_name /bin/bash -c "PGPASSWORD=pg_password psql -username pg_username database_name" /desired/path/on/your/machine/dump.sql Restore using psql This quickie assumes you have nothing directly installed on your development machine, so everything is run straight from and to the Docker PostgreSQL container you're running. Note: If you are attempting to restore data from a custom format dump, you should instead use pg_restore as I described in my How to set up and use Postgres locally article. Note: By default PostgreSQL keeps importing even when errors occur. Here is a link to official postgres tutorial.If you would instead prefer to stop the import completely upon error, be sure to add -set ON_ERROR_STOP=on to your above command. As an example, here is how you can create a new table. To run psql, you will first need to run a bash shell in the container, then connect to our database and finally run our SQL statements. To create database objects, we can either use pgAdmin or the psql command line. ![]() ![]() The hostname will once again be the ip address of the virtual machine. The database name, username and the password will be as specified in the yaml file. Once logged into pgAdmin, you will select the Add New Server option to connect to the postgres database. To log in, you will use the default email and password specified in the yaml file. To get the ip address, you can run the docker-machine ls command. However, since docker is running on Windows, pgAdmin cannot be accessed using Instead, you will need to use the ip address of the virtual machine that is running docker toolbox. The docker-compose.yml file specifies 8080 as the port to run pgAdmin. To verify if the docker containers are running, you can use the docker container ls command. To create the containers, you will need to run the docker-compose -f docker-compose.yml up command.
