Tar Usage / Cheat Sheet

e.g: tar -czvf name-of-archive.tar.gz /path/to/directory-or-file

-c: Create an archive.
-z: Compress the archive with gzip.
-v: makes tar talk a lot. Verbose output shows you all the files being archived and much.
-f: Allows you to specify the filename of the archive.

sudo apt-get install python3-pip

sudo pip3 install virtualenv

Change your database RDS instance security group to allow your machine to access it.
- Add your ip to the security group to acces the instance via Postgres.
Make a copy of the database using pg_dump
- $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
- you will be asked for postgressql password.
- a dump file(.sql) will be created
Restore that dump file to your local database.
- but you might need to drop the database and create it first
- $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>

You have to do 2 things in order to allow your container to access your host's postgresql database

Make your postgresql listen to an external ip address
Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf
