I have a custom Docker registry, accessible through http://localhost:5000
Here is the Apache config:
Listen 443
<VirtualHost *:443>
ServerName registry.mycompany.com
SSLEngine on
SSLCertificateFile ...
SSLCertificateKeyFile ...
SSLCACertificateFile /etc/pki/tls/certs/thawte.pem
ProxyPreserveHost On
ProxyPass / http://localhost:5000/
ProxyPassReverse / http://localhost:5000/
ProxyRequests Off
</VirtualHost>
And here how I start the registry:
docker run -d \
-p 5000:5000 \
-e REGISTRY_STORAGE_DELETE_ENABLED=true \
-e REGISTRY_AUTH=htpasswd \
-e REGISTRY_AUTH_HTPASSWD_REALM="Registro" \
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
--restart=always \
--name registro \
registry:2
Everything works ok (docker pull, ...), but docker push fails. After some retrying here is the error message shown:
first path segment in URL cannot contain colon

With docker compose, I use the image jwilder/nginx-proxy:alpine as a proxy, and it works much better
version: "3.7"
services:

- "./cors.conf:/etc/nginx/vhost.d/registro.fccma.com_location"

In this way, I can have the Docker registry and its corresponding GUI in the same host.
