Successfully deployed from a registry with a public cert.
A registry with a private/self-signed cert fails at the stager.
I've got the name of the registry in insecure_docker_registry_list and
insecure_docker_registry: true in the manifest.
On the cell, the garden-linux process is running with
-insecureDockerRegistryList=theregistryname.
On the stager, the stager process is running with -insecureDockerRegistry
-logLevel=info
Shouldn't theregistryname also be in stager arguments?

The error:

certificate signed by unknown authority. If this private registry supports
only HTTP or HTTPS with an unknown CA certificate, please add
`--insecure-registry theregistryname` to the daemon's arguments. In the
case of HTTPS, if you have access to the registry's CA certificate, no need
for the flag; simply place the CA certificate at
/etc/docker/certs.d/theregistryname/ca.crt

(change the hostname to "theregistryname" in this message...the real
hostname can be resolved and reached on each machine)
