docker tasks

some task that you can do using docker instead install the tool directly in your computer

commands

dump data from external database, important add the network of the container

docker run -it --rm -v ${PWD}:/tmp --network project_network_default postgres pg_dump -c -f /tmp/dump.sql postgresql://postgres:postgres@postgres:5432/postgres

dump just a table as inserts file, also on conflict do nothing so if found existent values would continue the script

docker run -it --rm -v $PWD:/tmp --network project_network_default postgres pg_dump --table=proof --column-inserts --data-only --on-conflict-do-nothing -f /tmp/table_data_patch.sql postgresql://postgres:postgres@postgres:5432/postgres

Deletes all the data, compilations, dumps, networks, its like a clean brand new docker installation, use with safety

docker system prune -a
