From dc80267b594e41cf7e223821dc1446683f0cae36 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Wed, 13 May 2020 13:44:29 +0200 Subject: compat handlers: add X-Registry-Auth header support * Support the `X-Registry-Auth` http-request header. * The content of the header is a base64 encoded JSON payload which can either be a single auth config or a map of auth configs (user+pw or token) with the corresponding registries being the keys. Vanilla Docker, projectatomic Docker and the bindings are transparantly supported. * Add a hidden `--registries-conf` flag. Buildah exposes the same flag, mostly for testing purposes. * Do all credential parsing in the client (i.e., `cmd/podman`) pass the username and password in the backend instead of unparsed credentials. * Add a `pkg/auth` which handles most of the heavy lifting. * Go through the authentication-handling code of most commands, bindings and endpoints. Migrate them to the new code and fix issues as seen. A final evaluation and more tests is still required *after* this change. * The manifest-push endpoint is missing certain parameters and should use the ABI function instead. Adding auth-support isn't really possible without these parts working. * The container commands and endpoints (i.e., create and run) have not been changed yet. The APIs don't yet account for the authfile. * Add authentication tests to `pkg/bindings`.
