What is the procedure for using pg_restore on Windows with Docker?

edit

To use pg_restore on Windows with Docker, follow these steps:

1. Install Docker Desktop on your Windows computer.

2. Start Docker Desktop and ensure that it is running.

3. Open a command prompt or terminal on your computer and navigate to the directory containing the PostgreSQL backup file (.tar) that you want to restore.

4. Run the following command to start a PostgreSQL container in Docker:

   docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 -v %CD%:/backup postgres
   

   This command will create a PostgreSQL container with the name "some-postgres", set the default password to "mysecretpassword", map the PostgreSQL port (5432) from the container to the host machine (Windows), and mount the current directory (%CD%) to the "/backup" directory in the container. This will allow you to easily access the backup file from within the container.

5. Run the following command to enter the container:

   docker exec -it some-postgres bash
   

6. Once you are inside the container, navigate to the "/backup" directory and run the following command to restore the backup file to the PostgreSQL database:

   pg_restore -U postgres -d <database_name> <backup_file_name>.tar
   

   Replace "<database_name>" with the name of the database you want to restore the backup to, and "<backup_file_name>" with the name of the backup file you want to restore.

7. Wait for the restore process to complete.

8. When the restore process is complete, exit the container by running the "exit" command.

9. Stop the PostgreSQL container by running the following command:

   docker stop some-postgres
   

You have successfully used pg_restore on Windows with Docker to restore a PostgreSQL backup file.
