Attached is the unit file (template type) I wrote and that works for me
to run multiple instances. It is important to give every instance
configuration file a different port number, like
version: 0.1
log:
fields:
service: registry
storage:
cache:
blobdescriptor: inmemory
filesystem:
rootdirectory: /var/lib/docker-registry/fedora_org
delete:
enabled: true
http:
addr: :5012
headers:
X-Content-Type-Options: [nosniff]
tls:
minimumtls: tls1.2
ciphersuites:
- TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
- TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
certificate: /etc/docker/registry/tls_cert.pem
key: /etc/docker/registry/tls_key.pem
proxy:
remoteurl: https://registry.fedoraproject.org
Of course, you can do it with containers as well. But then the question
is, would you want to run debian/ubuntu at all or use some simpler
distribution which more or less consists of container starting.
