CI failed with:

The following dependencies couldn't be met:
  - datakit-ci -> cohttp-lwt-unix >= 1.0.0
    no matching version

Maybe the Dockerfile FROM lines need updating?

[kit-ty-kate]

Yes probably.
Why is there this reset on 68b69980 in git -C /home/opam/opam-repository reset 68b69980 --hard ?

[kit-ty-kate]

Ok I got the answer to my own question.
Fixed.

You also need to change the FROM lines to use the opam2 images, e.g. something like:

diff --git a/Dockerfile b/Dockerfile
index 9833eaf..dd07d34 100644
--- a/Dockerfile
+++ b/Dockerfile
@@ -1,15 +1,10 @@
-FROM ocaml/opam-dev:alpine-3.5_ocaml-4.05.0
+FROM ocaml/opam2:alpine-3.6-ocaml-4.06.0@sha256:b93bd58dd2d32f0b7a6cd85fe2580ebee7452ef0174904b6a6b0a137c25f6d1b
 RUN sudo apk add --no-cache tzdata aspcud gmp-dev perl libev-dev m4

The opam-dev images are not maintained by @avsm anymore.

All green !!

@samoht The opam2 image(s ?) still fails to parse some packages so I'd let that as it is for now.

LGTM. Thanks for the patches!

[kit-ty-kate]

Thanks !! Is there a release planned soon by any chance ? :3
