Drone-runner-* Healthcheck End Point

Hi, currently I’m continuing my drone setup and using drone-runner-docker:1.6.3 on my own machine but one thing I’m missing or just oversight…

I’ve taken a look into the drone-runner-docker documentation which writes:

Use the docker logs command to view the logs and verify the runner successfully established a connection with the Drone server.

The question is: Does the drone-runner-docker (other drone-runners might be effected as well) has a health-check endpoint because unfortunately I couldn’t find anything in the docs…

It would make a lot of sense, cause I could enhance my docker-compose/stack file with a healthcheck to see if the connection to the server on the runners has been done successfully…

Hello khmarbaise,

This looks to be a valid ask, you could raise it here : Trello with the priority.

Hello khmarbaise,

You can expose port 3000 for the agent to access the following endpoint:

  • /varz returns some basic agent statistics, including currently running builds
  • /healthz returns 200 if agent is healthy
  • /version returns the version information

Please check if this helps otherwise raise it on Trello as suggested above.

Hi,
I have tested the suggestions you have given:

[root... ~]# docker ps -a 
CONTAINER ID        IMAGE                                      COMMAND                  CREATED             STATUS                     PORTS                                           NAMES
a117aa657242        drone/drone-runner-docker:1.6.3            "/bin/drone-runner-d…"   3 days ago          Up 3 days                  0.0.0.0:4000->3000/tcp                          drone_drone_runner_1_1
...
[[email protected] ~]# docker exec -it a117aa657242 /bin/sh
/ # wget  http://127.0.0.1:80/healthz
Connecting to 127.0.0.1:80 (127.0.0.1:80)
wget: can't connect to remote host (127.0.0.1): Connection refused
/ # wget  http://127.0.0.1:80/version
wget: can't connect to remote host (127.0.0.1): Connection refused
..

So I have tried to access the endpoint from inside the container which are obviously not available. Neither I have found some kind of endpoint definition within the code…(may be I oversight something) but based on my test I would say it does not exist…

So I will raise an issue on Trello…

Apart from that thanks for your answer…
Kind regards

So I have gone to Trello but unfortunately I can’t create some kind of entry there… maybe I just miss it… Can someone give me a short hint how to create an entry there… Many thanks in advance.

Kind regards

Hello khmarbaise,

You will need to create an account there and then you can raise it.
