Create and populate htpasswd file if missing #2362

liron-l · 2017-08-13T06:08:48Z

If htpasswd authentication option is configured but the htpasswd file is
missing, populate it with a default user and automatically generated
password.
The password will be printed to stdout.

cmd/registry/config-example.yml

+auth:
+  htpasswd:
+    realm: basic-realm
+    path: /auth/htpasswd


would prefer to use /var/lib/registry or something under /etc for the examples

Makes sense, I've put it under /etc/registry

This output looks kind of off

WARN[0000] htpasswd is missing. provisioned with default user:docker password: qakOn184C_WYgnUt7RDyE3xO7YrDkYhpqA9A2JbwIz0=

Maybe just getting rid of the space after password: would make it look more consistent. Also please use RawURLEncoding to get rid of the = at the end, some might find it confusing as to whether it is part of the password or part of an encoding.

Makes sense. I've removed the space and replaced the encoding method.

Put the bulk of the work in the main path, not the indented path.

Any other non-empty error should also be returned

Please use the logging system already used throughout the registry. We don't access logrus directly.

Also, use the field-based logging for these values, rather than just dumping them in the message.

Thanks @stevvooe can I use GetLoggerWithFields? if so, fixed.

Also, this message should explain the "escape hatch", as this will confusing to those who have already ran the registry. I'll discuss the "escape hatch" more on distribution/distribution-library-image#58.

@stevvooe but this config only apply if you start the registry with htpasswd enabled.
If you use REGISTRY_AUTH="" (or silly with realm) it is not enabled.

Is it OK to write
Disable default basic authentication by overriding the 'REGISTRY_AUTH' environment variable?

@liron-l If you are using the registry behind a proxy, which is an extremely common deployment, this will break them and those users will panic. What do they do when this happens?

@stevvooe I think the scenario you describe is relevant to the hub image change (which is indeed a breaking change).
However, here we just automatically populate the username/password when they are missing in basic auth scenario (like Jenkins does on default setup).

dmcgowan · 2017-10-11T18:55:42Z

Can you rebase this to get CI passing, circleci does not seem to be building from a merged branch even when I kicked it to run without cache

liron-l · 2017-10-11T19:31:18Z

Thanks @dmcgowan, The tests passed now.
I'm not sure the code coverage check is related to my change (they appear to be failing in other PRs)

@dmcgowan we broke something here. New PRs are not passing failing on gometalinter checks.

We cannot merge old PRs that haven't run Travis, we can kick it off by opening a dummy PR with the change commit or having them rebased

@dmcgowan agreed.
My bad on this one.
