Notes.md

Using an archive or git clone is the same in both

It's impossible to build an image with MIX_ENV=prod

The worst part comes after building the images and actually setting up pleroma

docker-compose run web mix generate_config

mkdir config
docker exec -i pleroma_web_run_1 cat config/generated_config.exs > config/prod.secret.ex
docker exec -i pleroma_web_run_1 cat config/setup_db.psql > config/setup_db.psql
docker exec -i pleroma_web_run_1 cat config/emoji.txt > config/emoji.txt

docker exec -i pleroma_postgres psql -U postgres < config/setup_db.psql

docker-compose run --rm web mix ecto.migrate WILL FAIL è_è
