git push：缺少托管GitLab存储库所需的主机头

Question

When I'm trying to git push -u origin master to my repository, I get 400 Bad Request . I've purposely redacted some information with < >. Recently unbundled nginx from gitlab-ee, and have verified accessibility via web browser to gitlab location. I've also tried setting the git remote-url to https://gitlab.<mysite>.com/<user>/project.git and the same thing happens.

Error when attempting git push

remote: 400 Bad Request: missing required Host header fatal: unable to access 'https://oauth2:<myawesometoken>.site.com/<user>/project.git/': The requested URL returned error: 400

Answer 1

So I figured it out by looking closer at GitLab documentation: https://docs.gitlab.com/omnibus/settings/nginx.html#vhost-server-block

I overlooked these two settings. This is inside the main server block.

# For protocol upgrades from HTTP/1.0 to HTTP/1.1 we need to provide Host header if its missing
if ($http_host = "") {
    # use one of values defined in server_name
    set $http_host_with_default "git.example.com";
}

if ($http_host != "") {
    set $http_host_with_default $http_host;
}

Also, I removed client_max_body_size from location / { ... } and put it in the parent scope.

Finally, I added gitlab_rails['internal_api_url'] = 'https://gitlab.<mysite>.com' to the gitlab.rb config file.

Everything is working now as it should.
