# testcontainers-modules

[](https://crates.io/crates/testcontainers-modules)
[](https://docs.rs/testcontainers-modules)
Community maintained modules for [testcontainers]
Provides modules to use for testing components in accordance with [testcontainers-rs].
Every module is treated as a feature inside this crate.
## Usage
1. Depend on [testcontainers-modules] with necessary features (e.g `postgres`, `minio` and etc)
- Enable `blocking` feature if you want to use modules within synchronous tests (feature-gate for `SyncRunner`)
2. Then start using the modules inside your tests with either `AsyncRunner` or `SyncRunner`
Simple example of using `postgres` module with `SyncRunner` (`blocking` and `postgres` features enabled):
```rust,ignore
use testcontainers_modules::{postgres, testcontainers::runners::SyncRunner};
#[test]
fn test_with_postgres() {
let container = postgres::Postgres::default().start().unwrap();
let host_ip = container.get_host().unwrap();
let host_port = container.get_host_port_ipv4(5432).unwrap();
}
```
**Note**: you don't need to explicitly depend on `testcontainers` as it's re-exported dependency
of `testcontainers-modules` with aligned version between these crates.
For example:
```rust
use testcontainers_modules::testcontainers::ImageExt;
```
You can also see [examples](https://github.com/testcontainers/testcontainers-rs-modules-community/tree/main/examples)
for more details.
### How to override module defaults (version, tag, ENV-variables)
Just use [RunnableImage](https://docs.rs/testcontainers/latest/testcontainers/core/struct.RunnableImage.html):
```rust,ignore
use testcontainers_modules::{
redis::Redis,
testcontainers::{ContainerRequest, ImageExt}
};
/// Create a Redis module with `6.2-alpine` tag and custom password
fn create_redis() -> ContainerRequest<Redis> {
Redis::default()
.with_tag("6.2-alpine")
.with_env_var("REDIS_PASSWORD", "my_secret_password")
}
```
