OK. That’d be great. Per the above, I wanted to do something like this:

I wanted to add this to `Dockerfile`:

```plaintext
# Add libmysqlclient-dev for running imports
RUN apt-get update && apt-get install -y libmysqlclient-dev

```

And also, the database stuff in the OP. I don’t fully understand the security implications of the `trust` that I suggested, but I can’t get backups to work without the change. This is what I’m doing to run an import in `discourse_dev`

```plaintext
./bin/docker/shell_root
rm /etc/apt/sources.list.d/google-chrome.list
apt update
apt -y install libmysqlclient-dev
sed -i -e 's/peer/trust/g' /etc/postgresql/9.5/main/pg_hba.conf
exit
docker restart discourse_dev
./bin/docker/shell
time bundle exec ruby /src/script/import_scripts/vbulletin.rb # for example

```
