Check this snippet out for how I set up my cluster: https://gitlab.com/snippets/1674542
I’m on gitlab 9.5.4, Kubernetes 1.6.9, and attempting to use the following Dockerfile and .gitlab-ci.yml to deploy a static website from gitlab
Dockerfile:
# This file is a template, and might need editing before it works on your project.
FROM httpd:alpine
RUN rm -rf srcimages
COPY ./ /usr/local/apache2/htdocs/
.gitlab-ci.yml:

The build step works, and I have an image posted to my container registry (127 MB!)
However, the review step fails with the following:

Unable to connect to the server: malformed HTTP response "\x15\x03\x01\x00\x02\x02"
ERROR: Job failed: error executing remote command: command terminated with non-zero exit code: Error executing in Docker Container: 1
I looked at the source code of the Kubernetes executor’s deploy command at https://gitlab.com/gitlab-examples/kubernetes-deploy/blob/master/deploy but I couldn’t identify what’s trying to connect to which HTTP server. The autogenerated review URL goes to “default backend - 404” and I don’t see any pods in my kubernetes cluster that correspond to the review, so I don’t know where it got hung up.
