These steps are mostly for moving development data around or pulling (partial) production data locally for debugging, or something along those lines. Thatll use your Dockerfile.pg to: build the postgres image and call it gis.
Running postgres in docker manual#
If you use any of these manual steps as a means to create backups, you're probably doing something not entirely correct. Please keep in mind that you should always ensure your production databases are properly backed up, and ideally automatically so. 17 Answers Sorted by: 647 You can run Postgres this way (map a port): docker run -name some-postgres -e POSTGRESPASSWORDmysecretpassword -d -p 5432:5432 postgres So now you have mapped the port 5432 of your container to port 5432 of your server. There are certainly other ways to achieve something similar, but this method will work in a pinch. So instead of installing PostgreSQL as a separate application, we'll use Docker Compose to run Spring Boot and PostgreSQL.
In a previous article, we looked at Docker Compose to handle multiple containers at once. manually created) container to another, you could use pipes to do this in one command, like so: docker exec -i pg_old_container_name /bin/bash -c "PGPASSWORD=pg_password pg_dump -username pg_username database_name" | docker exec -i pg_new_container_name /bin/bash -c "PGPASSWORD=pg_password psql -username pg_username database_name" Conclusions Introduction In this tutorial, we want to run a Spring Boot application with the popular open-source database PostgreSQL. If you, for example, are moving data from one (e.g. 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. Note: By default PostgreSQL keeps importing even when errors occur.

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. sh scripts found in that directory to do further initialization before starting the service. sh scripts, and source any non-executable.
Running postgres in docker password#
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" < /path/on/your/machine/dump.sql After the entrypoint calls initdb to create the default postgres user and database, it will run any. Dump using pg_dump docker exec -i pg_container_name /bin/bash -c "PGPASSWORD=pg_password pg_dump -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. Depending on why you need to dump/restore a database, this might help for you, too. I ran into this just today, and thought I'd share one method that I felt was easy, fast and served my purpose.
However, I thought combining two containers in docker-compose.yml would let me run psql but apparently not.: Updated the guide with a more up-to-date method for sending a password along with the commands. Since the app container does not have postgres installed, it won't be able to run psql by itself. Suppose I have an app in the appcontainer that runs the psql command (just a one liner python script with os.command("psql")). My understanding of docker compose is that I can combine two containers so that they can communicate with each other. I'm having trouble connecting postgresDB to my app using docker-compose
