## Installation
|
|
|
|
### Docker (Recommended)
|
|
|
|
```bash
|
|
docker pull bootmediaalix/snowflakeservice
|
|
docker run -e %{set required .env, see below} -p 9567:9567 -v %{desired path on host}:/data/b00tload-tools/snowflake bootmediaalix/snowflakeservice
|
|
```
|
|
### Containerless
|
|
A containerless installation is possible, although not supported. For development convenience the application base directory is located in `~/.b00tload-tools/snowflake` instead of `/data/b00tload-tools/snowflake`.
|
|
If you want to work containerless you are on your own.
