Excellent!

ubuntu:latest doesn’t work as well

Any update about this yet? Don’t want to seem pushy, just checking in if there’s new info!

We had to delay our host kernel upgrade maintenance the other day because we found another issue.

We’ve implemented a fix for this other issue and are still observing.

We should be able to reschedule the host kernel upgrade maintenance soon and it should fix this segmentation fault issue.

Can I hijack this thread to ask you how to spin up a plain ol’ ubuntu instance on fly (that I can ssh into?)

Right now I’m getting Failed due to unhealthy allocations on deploy, presumably because my container exits and doesn’t wait for any incoming SSH connections.

2022-07-08T19:03:52Z   [info]2022/07/08 19:03:52 listening on [fdaa:0:6cb4:a7b:23c6:6cf7:258a:2]:22 (DNS: [fdaa::3]:53)

2022-07-08T19:03:53Z   [info]Starting clean up.
--> v3 failed - Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v4

Is there a recommended way of doing this on fly?

For the record, I want to spin up an Ubuntu instance to test connecting to my redis app on fly.io using an .internal address!

Try putting CMD ["sleep", "infinity"] at the end of your Dockerfile. And put an empty [[services]] block in fly.toml.

This worked. Thank you!

@technillogue @ryansch @codearchitect @merlin we’ve upgraded our hosts today and using these images should now work everywhere.

I just shipped a phx app with:

ARG BUILDER_IMAGE="hexpm/elixir:1.13.4-erlang-25.0.2-ubuntu-jammy-20220428"
ARG RUNNER_IMAGE="ubuntu:jammy-20220428"

IT’S WORKING!
