Brouillon, insecure registry

/etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=http://192.168.56.1:3128/" "HTTPS_PROXY=http://192.168.56.1:3128/" "NO_PROXY=localhost,127.0.0.0/8,192.168.0.0/16,registry.local"

systemctl daemon-reload
systemctl restart docker

Vérif

systemctl show --property=Environment docker

/etc/hosts

192.168.205.18 docker-1

API

curl -X GET -u <user>:<pass> https://myregistry:5000/v2/_catalog
curl -X GET -u <user>:<pass> https://myregistry:5000/v2/ubuntu/tags/list

sudo mkdir -p /etc/docker/certs.d/registry.local:5000

Puis déposer le fichier ca.crt dans ce dossier.

Autre solution

/etc/docker/daemon.json

{
    "log-level":        "error",
    "insecure-registries" : ["docker-1.local"],
    "proxies": {
      "http-proxy": "http://192.168.1.100:3128",
      "https-proxy": "https://192.168.1.100:3128",
      "no-proxy": "*.local,127.0.0.0/8"
  }
}

Old
Ne semble plus marcher.
Avant nous pouvions spécifier un numéro de port au registry Docker.

/etc/docker/daemon.json

{
          "insecure-registries" : ["docker-1:5000"]
}

mkdir docker-registry
cd docker-registry
 
mkdir certs
openssl req -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key -x509 -days 365 -out certs/domain.crt
 
chmod a+r certs/domain.*
sudo mv certs /certs

Be sure to use the name myregistrydomain.com as a CN
