[biolounge]

Using swift backend as storage for registry is failing with following error (registry.log).

We looked in the swift logs and there are no authentication errors.

See the below keystone logs: 2016-09-12 14:52:04.863 24657 INFO keystone.common.wsgi [req-34a5a1fa-ba22-43f5-a640-be037db8a7a9 - - - - -] POST http://xxxxx.xxx.com:5000/v3/auth/tokens 2016-09-12 14:52:05.064 24657 INFO keystone.token.providers.fernet.utils [req-34a5a1fa-ba22-43f5-a640-be037db8a7a9 - - - - -] Loaded 2 encryption keys (max_active_keys=3) from: /etc/keystone/fernet-keys/

Let me know if you need more information.

@biolounge The swift storage is provided by Docker distribution. Could you provide the configuration of swift backend? Have you configured something similar to our guide https://github.com/vmware/harbor/blob/master/docs/installation_guide.md ?

Need to replace the username/password and keystone endpoint.

storage: swift: username: admin password: ADMIN_PASS authurl: http://keystone_addr:35357/v3 tenant: admin domain: default region: regionOne container: docker_images

[biolounge]

We followed the guide you mentioned above. Please see the swift backend configuration.

version: 0.1 log: level: debug fields: service: registry storage: cache: layerinfo: inmemory swift: username: admin password: **** authurl: http://xxxx.xxxx.xxx:5000/v3 tenant: admin domain: default insecureskipverify: true region: regionOne container: docker_images

maintenance: uploadpurging: enabled: false delete: enabled: true

admin account and tenant are available in Openstack keystone.

@biolounge I use keystone v2, it woks. I am not sure if v3 can work. This is my config:

version: 0.1
log:
  fields:
    service: registry
storage:
  swift:
    tenant: admin
    username: admin
    password: 5c8d15f732104053
    authurl: http://10.0.10.216:5000/v2.0
    container: docker_registry
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3

Be sure that the swift container docker_registry is created before you start registry/harbor service .

@biolounge for swift v3, the auth URL may look like: https://storage.myprovider.com/v3/auth

For more info, refer to https://docs.docker.com/registry/configuration/

[biolounge]

Yes, that solved the issue!
