I try to setup nexus docker repository behind nginx reverse-proxy (with a self-signed SSL certificate). I use this official docker-compose file:
https://github.com/sonatype-nexus-community/docker-nginx-nexus-repository
After installing docker-compose I eventually was able to launch the two containers: nexus3 and nginx with ./nexus.sh. It took me several attempts as I had to change nexus pasword to admin123 and add nexus.scripts.allowCreation=true inside of the docker-nginx-nexus-repository_nexus-repository_1 container (in /nexus-data/etc/nexus.properties) otherwise curl -v -u admin:admin123 --insecure --header 'Content-Type: application/json' 'https://localhost/service/rest/v1/script' -d @nexus-repository/create-docker-proxy.json would fail. At the end I had nexus with docker-proxy repository on http port 5000 pointing on DockerHub.
Furthermore on the host I added:
cat /etc/docker/daemon.json
{
"insecure-registries": ["10.97.7.95:5000"]
}
And:
cat /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTPS_PROXY=https://10.97.7.95:5000/"
And restarted docker.
However once I try to pull some images while being on the host, I get follwoing errors:
# docker pull 10.97.7.95:5000/hello-world
Using default tag: latest
Error response from daemon: error parsing HTTP 400 response body: invalid character '<' looking for beginning of value: "<html>\r\n<head><title>400 The plain HTTP request was sent to HTTPS port</title></head>\r\n<body>\r\n<center><h1>400 Bad Request</h1></center>\r\n<center>The plain HTTP request was sent to HTTPS port</center>\r\n<hr><center>nginx/1.19.0</center>\r\n</body>\r\n</html>\r\n"
