Cert-manager: Latest cert-manager-acmesolver docker image contains arm binary

[PabloCastellano]

Describe the bug:

Apparently the latest version of the image comes with a binary compiled for arm instead of amd64 as previous versions did, hence breaking compatibility.

I have verified it by running the image locally in my laptop and by inspecting the image using dive.

I'm not familiar with the build process using bazel so I have not gone further. Have been running cert-manager during months without problem and apparently the last push to quay.io/jetstack/cert-manager-acmesolver updated the canary tag 20h ago and introduced this breaking change according to quay.

Expected behaviour:
The docker image should contain a amd64 binary.

Steps to reproduce the bug:
Run the following command from a amd64 machine:

$ docker run --rm -ti quay.io/jetstack/cert-manager-acmesolver:canary bash
standard_init_linux.go:190: exec user process caused "exec format error"

Anything else we need to know?:

Environment details::

• Kubernetes v1.9
• Cloud-provider/provisioner: AWS/kube-aws
• cert-manager version (e.g. v0.4.0): stable/0.5.0
• Install method: Helm

Thanks for the report - I have confirmed this and tracked it down to only the latest image tag:

$ docker run --entrypoint=uname --rm -ti quay.io/jetstack/cert-manager-acmesolver:2e95421d -a
Linux 9d97cb920973 4.9.125-linuxkit #1 SMP Fri Sep 7 08:20:28 UTC 2018 x86_64 Linux

$ docker run --entrypoint=uname --rm -ti quay.io/jetstack/cert-manager-acmesolver:a06d888a -a
Linux ff55648c09bf 4.9.125-linuxkit #1 SMP Fri Sep 7 08:20:28 UTC 2018 armv7l Linux

It appears the build job in question failed after pushing the acmesolver image, which seems highly suspect (https://storage.googleapis.com/jetstack-logs/logs/post-cert-manager-release-canary/1124363456384864256/build-log.txt)

We've been working on a new release tool in time for v0.8 that recently merged, and there are clearly some issues still at the moment.

For the time being, please use a versioned release of cert-manager - I'll put a patch together to fix this up shortly!
