## Docker
|
|
|
|
|
|
|
|
|
|
### 1. Configure
|
|
|
|
|
|
|
|
|
|
mcaptcha is highly configurable.
|
|
|
|
|
|
|
|
|
|
Configuration is applied/merged in the following order:
|
|
|
|
|
|
|
|
|
|
1. path to configuration file passed in via `MCAPTCHA_CONFIG`
|
|
|
|
|
2. `./config/default.toml`
|
|
|
|
|
3. `/etc/mcaptcha/config.toml`
|
|
|
|
|
4. environment variables.
|
|
|
|
|
|
|
|
|
|
See
|
|
|
|
|
[CONFIGURATION.md](https://github.com/mCaptcha/mCaptcha/tree/master/docs/CONFIGURATION.md)
|
|
|
|
|
for configurable options.
|
|
|
|
|
|
|
|
|
|
### 2. Run image
|
|
|
|
|
|
|
|
|
|
If you have already have a Postgres instance running, then:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
docker run -p <host-machine-port>:<port-in-configuration-file> \
|
|
|
|
|
--add-host=database:<database-ip-addrss> \
|
|
|
|
|
-e RUST_LOG=debug \
|
|
|
|
|
-e DATABASE_URL="postgres://<db-user>:<db-password>@database:<db-port>/<db-name>" \
|
|
|
|
|
mcaptcha/mcaptcha:latest
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
If you don't have a Postgres instance running, you can either install
|
|
|
|
|
one using a package manager or launch one with docker. A [docker-compose
|
|
|
|
|
configuration]('../docker-compose.yml) is available that will launch both
|
|
|
|
|
a database instance mcaptcha instance.
|
|
|
|
|
|
|
|
|
|
## With docker-compose
|
|
|
|
|
|
|
|
|
|
1. Follow steps above to build docker image.
|
|
|
|
|
|
|
|
|
|
2. Set database password [docker-compose configuration]('../docker-compose.yml).
|
|
|
|
|
|
|
|
|
|
3. Launch network
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
docker-compose up -d
|
|
|
|
|
```
|
