problem：
If I want to write elasticsearch through HTTPS, how can I solve it

[QeelinDarly]

I have the same problem in my system. Do you have any idea?

[QeelinDarly]

Hi, I built a docker image to solve this problem. You can get image from https://hub.docker.com/r/chrysanthe/log-pilot and add two environment variables in it.

env:
  - name: "ELASTICSEARCH_SSL_VERIFY"
    value: "false"
  - name: "ELASTICSEARCH_SSL_VERSION"
    value: "TLSv1_2"

After that, you will ignore your ssl verify. You'd better download with tag 0.9.7-fluentd-0.0.8dst
