Try this inside the docker container:

```bash
apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y libmysqlclient-dev
su discourse -c 'export IMPORT=1; bundle install --no-deployment --without test --without development --path vendor/bundle'
su discourse -c 'export IMPORT=1; bundle exec ruby script/import_scripts/vanilla_mysql.rb'

```
