+### Run function
+
+- Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+The CosmosDB module exposes one entrypoint function to create the CosmosDB container, and this function receives three parameters:
+
+```golang
+func Run(ctx context.Context, img string, opts ...testcontainers.ContainerCustomizer) (*Container, error)
+```
+
+- `context.Context`, the Go context.
+- `string`, the Docker image to use.
+- `testcontainers.ContainerCustomizer`, a variadic argument for passing options.
+
+#### Image
+
+Use the second argument in the `Run` function to set a valid Docker image.
+In example: `Run(context.Background(), "mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:vnext-preview")`.
+
+### Container Options
+
+When starting the CosmosDB container, you can pass options in a variadic way to configure it.
+
+{% include "../features/common_functional_options_list.md" %}
