Docker is useful for running the TFGridDb in container environment. Read this to [install Docker engine](system_administrators@@docker_basics.md#install-docker-desktop-and-docker-engine).
Note: it will be necessary to follow step #2 in the previous article to run docker without sudo. if you want to avoid that. edit the docker commands in the `Makefile` and add sudo.
## Postgres
If you have docker installed you can run postgres on a container with:
```bash
make db-start
```
Then you can either load a dump of the database if you have one:
```bash
make db-dump p=~/dump.sql
```
or easier you can fill the database tables with randomly generated data with the script `tools/db/generate.go` to do that run:
```bash
make db-fill
```
