Hello,

 

I am trying to add my custom Nexus private docker registry to the `insecure-registry` settings in the deamon.json config file for docker as mentionned here: https://docs.docker.com/registry/insecure/

 

But I cannot find that file or any other config that would allow me to do that.

 

Anybody has been able to successfully do it?

 

Thanks,

 

Phil

For anyone who is also seeking the answer:

 

Use self signed certificates on your docker registry, then copy the crt file to the following folder in your UNRAID:
/etc/docker/certs.d/myregistrydomain.com:5000/ca.crt

 

For detail instruction you can checkout https://docs.docker.com/registry/insecure/#use-self-signed-certificates

The default configuration file location is /etc/docker/daemon.json, if not exist then create one, set the configuration like bellow:

{
  "insecure-registries": [
    "your local ip address:5000"
  ]
}

restart docker with :　/etc/rc.d/rc.docker restart

it seems like creation of /etc/docker/daemon.json does not survive shutdown/restart cycle of the unraid server.

Of course such settings have to persist somewhere, i guess it has to be somewhere in the /boot folder (the stick)

 

I added 3 lines to the /boot/config/go script to create daemon.json during boot:

# Setup docker daemon.json
mkdir /etc/docker
echo {\"insecure-registries\": [\"192.168.0.54:5000\"]} > /etc/docker/daemon.json

But I guess there must be a better solution than that.

 

 

Unraid runs from RAM. Changes do not persist across reboots unless additional steps have been taken to persistent to the flash drive and reloaded on startup. Most users use the plugin "User Scripts" to run and manage customizations like that.

What worked for me was editing the '/boot/config/docker.cfg' file with

$ nano /boot/config/docker.cfg

and appending:

DOCKER_OPTS="--insecure-registry YOUR_REGISTRY_IP:YOUR_REGISTRY_PORT"

Then you need to restart the docker service to apply the changes with:

$ /etc/rc.d/rc.docker restart

This is also persistent across reboots.

Thank you! This worked for me. Haven't restarted yet, so I can't speak to the persistence, but so far so good.
