To configure Docker to push images to Artifactory using SSL on a port other than port 443, do the following:
1. Edit your .dockercfg file (typically located in your docker-user's home directory) so the URL will include the SSL listening port. For example:
{
"https://docker.example.com:5000" :
{
"auth" : "YWRtaW46QVAyZFVadUM0WEh4Z1Q2cld1aHExdlNBMkRk",
"email" : "abcd@yourdomain.com"
}
}
2. Edit your nginx.conf file to listen to the SSL port and add that port to the proxy_set_header Host $host line.
For example:
listen 5000 ssl; proxy_set_header Host $host:5000;
Reload Nginx after making the changes above (sudo nginx -s reload).
3. Tag the Docker image that you want to push, such that it will include the SSL port. For example:
docker tag ubuntu docker.example.com:5000/ubuntu
4. Run docker push to push the image. For example:
docker push docker.example.com:5000/ubuntu
