Hello,
I do not use Mesos currently but this is what I did in the Docker settings.
If you don't care about encryption you can tell docker to use an insecure
registry. On /etc/docker/daemon.json:
{
"insecure-registries" : [ "myregistrymachine.domain:port" ],
"features": {
"buildkit": true
}
}
Where port is your registry port (5000, etc.)
Then restart Docker daemon (systemctl restart docker.service for example)
And confirm the insecure registry is there: docker info
If you have setup user authentication you can test this with docker login:
docker login myregistrymachine.domain:port
[YYYY@ZXXXX ~]$ docker login myregistrymachine.domain:port
Authenticating with existing credentials...
WARNING! Your password will be stored unencrypted in
/home/YYYY/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
Hope this helps.

Subject: Docker registry without HTTPS
Hi all,
I’m running a Docker registry in my cluster network that does plain HTTP, no
HTTPS. I tried to configure it using docker_registry and docker_config
options, providing an http:// address. When I try to run a Docker image in a
task it fails and I see in the log a message that CURL SSL got a malformed TLS
answer. So apparently Mesos still tells curl to do whatever it should do via
HTTPS.
I have seen posts that seem to indicate that it will switch to HTTP
automatically when you provide port ‘:80’ as part of the URI for the registry.
However, I cannot put the registry on 80 because there is already a Webserver
sitting that is used for distributing artefacts in the cluster.
—> Is there a way to tell Mesos that it (respectively curl) use HTTP instead of
HTTPS?
Thanks and best regards,
Ben
PS: I also saw in the logs:
curl: option —http1.1: is unknown
curl: try ‘curl —help’ or ‘curl —manual’ for more information
