Hi,
I am using a Docker setup, running on AWS EC2, that is orchestrated via Ansible. In short, I run an Ansible playbook that connects to EC2m and then starts Drone Server, a Drone Agent, and Postgres; all of them as Docker containers.
After that I can access Drone UI and I am able to activate a Github repository that I use for testing. I can see the webhook is properly setup on Github.
Then I add and push a Drone file to test it out, Drone gets the trigger from Github webhook but the build gets stuck in Pending state.
This is the Drone file that I use for testing:
$ cat .drone.yml
kind: pipeline
type: docker
name: default
steps:
- name: tests
image: golang:1.14.4-alpine3.12
commands:
- pwd
Here’s the output of docker ps after all the containers are up and running:
# docker ps

I can’t understand what’s wrong with my setup but here’s some specific questions I need help with:
1- It is not clear if the agent is able to reach the server at any time, or just after the first time and not after. That honestly looks ambiguous to me.
2- I set DRONE_RPC_PROTO env var to “http” because I thought that would fix the unsupported protocol scheme error but that did not help.
3- Also I don’t know why the agent assumes the Drone Server is running at localhost:8080. I’m setting DRONE_RPC_HOST and DRONE_RPC_SERVER env vars to drone-server:9000 but that doesn’t seem to change much.
Thanks for any help on this in advance!
