Setting up Apache to work with multiple Docker repositories

To have multiple docker repositories in Artifactory, you’ll need to setup different SSL ports (e.g have several VirtualHosts) on your Apache configuration. For example, your default-ssl.conf file may look similar to this –

<VirtualHost *:443>
ServerName dockerone.com

SSLEngine on
SSLCertificateFile /etc/ssl/certs/docker-registry
SSLCertificateKeyFile /etc/ssl/private/docker-registry.key

ProxyRequests off
ProxyPreserveHost on

ProxyPass / http://localhost:9999/artifactory/api/docker/docker-local/
ProxyPassReverse / http://localhost:9999/artifactory/api/docker/docker-local/
</VirtualHost>

<VirtualHost *:442>
ServerName dockertwo.com

SSLEngine on
SSLCertificateFile /etc/ssl/certs/docker-registry
SSLCertificateKeyFile /etc/ssl/private/docker-registry.key

ProxyRequests off
ProxyPreserveHost on

ProxyPass / http://localhost:9999/artifactory/api/docker/docker-local-2/
ProxyPassReverse / http://localhost:9999/artifactory/api/docker/docker-local-2/
</VirtualHost>

To use a non-standard SSL port on a VirtualHost (like 442 in the above example), it is also required to add this to your /etc/apache2/ports.conf file with –

NameVirtualHost *:442
Listen 442

Finally, you need to setup your .dockercfg to manage your credentials per each of the registries, e.g –

{

"https://localhost:442" : {

"auth" : "YWRtaW46QVAzSEZ4UnFhemhoUzlVV2trTFZCMnNHTmlE",

"email" : ""

},

"https://localhost:443" : {

"auth" : "YWRtaW46QVAzSEZ4UnFhemhoUzlVV2trTFZCMnNHTmlE",

"email" : ""

}

}
