+# InfluxDB
+
+Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+## Introduction
+
+A testcontainers module for InfluxDB.  This module supports v1.x of InfluxDB.   
+
+## Adding this module to your project dependencies
+
+Please run the following command to add the InfluxDB module to your Go dependencies:
+
+```
+go get github.com/testcontainers/testcontainers-go/modules/influxdb
+```
+
+## Usage example
+
+<!--codeinclude--> 
+[Creating an InfluxDB container](../../modules/influxdb/examples_test.go) inside_block:runInfluxContainer
+<!--/codeinclude-->
+
+## Module Reference
+
+The InfluxDB module exposes one entrypoint function to create the container, and this function receives two parameters:
+
+```golang
+func RunContainer(ctx context.Context, opts ...testcontainers.ContainerCustomizer) (*InfluxDbContainer, error) {}
+```
+
+- `context.Context`, the Go context.
+- `testcontainers.ContainerCustomizer`, a variadic argument for passing options.
+
+### Container Options
+
+When starting the container, you can pass options in a variadic way to configure it.
+
+!!!tip
+
+    You can find configuration information for the InfluxDB image on [Docker Hub](https://hub.docker.com/_/influxdb) and a list of possible 
+    environment variables on [InfluxDB documentation](https://docs.influxdata.com/influxdb/v1/administration/config/).
+
+#### Image
+
+To use a different Docker image, you can use the `testcontainers.WithImage` option to specify the 
+image, E.g. `testcontainers.WithImage("influxdb:1.8.0")`.  By default, the 1.8.10 image is used.  Note that
+`influxdb:latest` will get you a version 2 image which is not supported by this module.
+
+
+{% include "../features/common_functional_options.md" %}
+
+#### Set username, password and database name
+
+By default, authentication is disabled and no credentials are needed to use the Influx API against the test container.
+If you want to test with credentials, include the appropriate environment variables to do so.
+
+#### Init Scripts
+
+While the InfluxDB image will obey the `/docker-entrypoint-initdb.d` directory as is common, that directory does not
+exist in the default image. Instead, you can use the `WithInitDb` option to pass a directory which will be copied to
+when the container starts. Any `*.sh` or `*.iql` files in the directory will be processed by the image upon startup.
+When executing these scripts, the `init-influxdb.sh` script in the image will start the InfluxDB server, run the
+scripts, stop the server, and restart the server.  This makes it tricky to detect the readiness of the container.
+This module looks for that and adds some extra tests for readiness, but these could be fragile.
+
+!!!important
+    The `WithInitDb` option receives a path to the parent directory of one named `docker-entrypoint-initdb.d`. This is
+    because the `docker-entrypoint-initdb.d` directory is not present in the image.
+
+#### Custom configuration
+
+If you need to set a custom configuration, you can use `WithConfigFile` option to pass the path to a custom configuration file.
+
+### Container Methods
+
+#### ConnectionUrl
+
+This function is a simple helper to return a URL to the container, using the default `8086` port.
+
+<!--codeinclude-->
+[ConnectionUrl](../../modules/influxdb/influxdb_test.go) inside_block:influxConnectionUrl
+<!--/codeinclude-->
+
+Please check the existence of two methods: `ConnectionUrl` and `MustConnectionUrl`. The latter is used to avoid the need to handle errors,
+while the former is used to return the URL and the error. `MustConnectionUrl` will panic if an error occurs.
+
+!!!info
+    The `ConnectionUrl` and `MustConnectionUrl` methods only support HTTP connections at the moment.
