I'm using prometheusIngester module to query my prometheus instance. It is behind a web proxy that does the SSL termination. I'm getting the following issue when using the default Docker image from dockerhub.

slo-exporter_1  | time="2021-02-08T15:45:32.03454Z" level=error msg="failed querying Prometheus: 'Post "https://my-prometheus.com": x509: certificate signed by unknown authority'" component=prometheusIngester query="http_server_requests_seconds_count"

To fix that I need to manually install ca-certificates, ending up with the following Dockerfile

FROM seznam/slo-exporter:v6.7.0

RUN apt update && apt install ca-certificates -y

I can send a PR adding this line if you agree.

Hi, thanks for rising the issue!
Your request sounds reasonable to me, so please feel free to send the PR 👍

Just please add also the apt clean after the installation to keep the image small as possible.
Thanks!
