Pull
```
git clone https://github.com/shadowban-eu/shadowban-eu-backend && cd shadowban-eu-backend
```
### Docker
Add config
```
cp ~/configs/.env.development|production ./
cp ~/configs/.htaccounts
Follow the quickstart instructions in our docker repo's [README](https://github.com/shadowban-eu/docker#shadowbandev).
### Install/Run
```bash
$ git clone https://github.com/shadowban-eu/testing ./testing; cd $_
$ ./bin/install.sh
$ ./bin/docker-entry.sh .env.example # takes any .env file
```
Run
`./run.sh development|production`
### Memory Profiling
Using [memory-profiler](https://pypi.org/project/memory-profiler/) to debug memory usage:
See [.env.example](https://github.com/shadowban-eu/shadowban-eu-backend/blob/dev/.env.example) for .env variables
```bash
# When env vars are already set
$ ./bin/docker-entry.sh mprof
# Otherwise, read from file
$ ./bin/docker-entry.sh .env.example mprof
# Passes remaining arguments to mprof (set interval to 5s)
$ ./bin/docker-entry.sh .env.example mprof -T 5
```
