Hrm, had never seen this, but a quick Google search turns up this issue: https://github.com/docker-library/busybox/issues/80 And as I think the Prometheus docker images are based on busybox, this might explain the wget problem. I don't think a missing openssl implementation would cause issues for blackbox_exporter, as it uses Go's http/tls stack, as far as I understand. However, it might still rely on some default certificates. I suggest trying to get more blackbox_exporter logs and maybe trying to place a (relevant) ca bundle in the proper paths.
