+# Testcontainers InfluxDB testing module
+
+Testcontainers module for the InfluxData [InfluxDB](https://github.com/influxdata/influxdb).
+
+## Usage example
+
+Running influxDbContainer as a stand-in for InfluxDB in a test:
+
+```java
+public class SomeTest {
+
+    @Rule
+    public InfluxDBContainer influxDbContainer = new InfluxDBContainer();
+
+    @Test
+    public void someTestMethod() {
+         InfluxDB influxDB = influxDbContainer.getNewInfluxDB();
+         ...
+```
+
+## Dependency information
+
+Replace `VERSION` with the [latest version available on Maven Central](https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.testcontainers%22).
+
+[![](https://api.bintray.com/packages/testcontainers/releases/testcontainers/images/download.svg)](https://bintray.com/testcontainers/releases/testcontainers/_latestVersion)
