404 when executing docker push to gitlab-container-registry

I have installed gitlab-ce 13.2.0 on my server and the container-registry was immediately available.

from a other sever (or my local machine) I can login, but when pushing a image to the container-registry I get a 404-error: error parsing HTTP 404 response body: invalid character '<' looking for beginning of value: "<!DOCTYPE html>\n<html>\n<head>...

in my gitlab.rb I have:

external_url 'https://git.xxxxxxxx.com'
nginx['enable'] = true
nginx['client_max_body_size'] = '250m'
nginx['redirect_http_to_https'] = true

nginx['ssl_certificate'] = "/etc/gitlab/trusted-certs/xxxxxxxx.com.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/trusted-certs/xxxxxxxx.com.key"
nginx['ssl_protocols'] = "TLSv1.1 TLSv1.2"

registry_external_url 'https://git.xxxxxxxx.com'

what is confusing, is that the registry_external_url is the same as the external_url. There are those lines in the gitlab.rb:

### Settings used by GitLab application
# gitlab_rails['registry_enabled'] = true
# gitlab_rails['registry_host'] = "git.xxxxxxxx.com"
# gitlab_rails['registry_port'] = "5005"
# gitlab_rails['registry_path'] = "/var/opt/gitlab/gitlab-rails/shared/registry"

But when I uncomment this, I cannot login.

what can be the problem here?

You should make sure you are using the right port:

registry_external_url = "https://gitlab.*****.com:5050"
registry_nginx['enable'] = true
registry_nginx['listen_https'] = true
registry_nginx['redirect_http_to_https'] = true
gitlab_rails['registry_enabled'] = true
gitlab_rails['registry_host'] = "gitlab.*****.com"
gitlab_rails['registry_port'] = "5050"

and the system listening to that port; when you run netstat -tunlp

tcp        0      0 0.0.0.0:5050            0.0.0.0:*               LISTEN      708263/nginx: maste

And from client where you want to push the image:

docker login gitlab.*****.com:5050
docker build -t gitlab.*****.com:5050/frontend/app:1.0 .
docker push gitlab.*****.com:5050/frontend/app:1.0

This is actually because you are using https port without proxying the registry in nginx.

Fix these lines according to the following in gitlab.rb:

registry_nginx['enable'] = true
registry_nginx['listen_https'] = true
registry_nginx['redirect_http_to_https'] = true
registry_external_url 'https://registry.YOUR_DOMAIN.gtld'

You don't need to touch nginx['ssl_*] parameters when you are using letsencrypt since the chef would take care.

How is your image named? Your image name must match exactly not only the registry URL, but project too.

You can't just build "myimage:latest" and push it. It must be like git.xxxxxxxx.com/mygroup/myproject:latest. You can obtain correct name from $CI_REGISTRY_IMAGE predefined variable.
