# Selfhosting Trashmail API
|
||||
|
||||
Basic self hosting trashmail API using docker NodeJS, Redis, NGINX + LUA
|
||||
|
||||
|
||||
Requirements
|
||||
---
|
||||
* Docker
|
||||
* [Docker-Compose](https://docs.docker.com/compose/)
|
||||
|
||||
|
||||
Installation
|
||||
---
|
||||
You need to set permissions right to allow npm to run `npm install`
|
||||
```
|
||||
chmod -R 777 node
|
||||
docker-compose up
|
||||
```
|
||||
|
||||
Use the `-d` option to run the containers in daemon mode, and `docker-compose logs -f` to watch logs
