Some plugins require additional packages to be installed. For example, the `ntpq` plugin requires `ntpq` command. It is recommended to create a custom derivative image to install any needed commands.
As an example this Dockerfile add the `mtr-tiny` image to the stock image and save it as `telegraf-mtr.docker`:
```dockerfile
FROM telegraf:1.12.3
RUN DEBIAN_FRONTEND=noninteractive \
apt-get update && apt-get install -y --no-install-recommends mtr-tiny && \
RUN apt-get update && apt-get install -y --no-install-recommends mtr-tiny && \
rm -rf /var/lib/apt/lists/*
```
Build the derivative image:
```console
$ docker build -t telegraf-mtr:1.12.3 - < telegraf-mtr.docker
```
Create a `telegraf.conf` configuration file:
```toml
[[inputs.exec]]
interval = "60s"
