backend/azurerm: upgrading the SDK / support for proxies #19414

tombuildsstuff · 2018-11-20T15:51:27Z

This PR upgrades to v21.3.0 of github.com/Azure/azure-sdk-for-go, v10.15.4 of github.comAzure/go-autorest and vendors github.com/hashicorp/go-azure-helpers @ 0.1.1

This is the first in a couple of PR's to the Backend which allows us to support additional authentication modes for the backend, which will allow us to fix #18425 and #16763.

This PR intentionally doesn't fix the locking issue tracked in #17046 (see more details below) - however it should be possible to fix that once this is merged (since this changeset's already quite big)

Tasks:

Upgrade Azure/go-autorest / Azure/azure-sdk-for-go
Threading through the new auth package
Proxy Support
Switching to use the Resources Profile
Switching to use the Storage Profile
Setting the User Agent
Additional Acceptance Tests coverage for Service Principal Client Secret / Access Key
Manual Testing

The underlying issue is being tracked in #17046 - since this functionality is currently broken in master, I'm going to tackle this in the next PR, since this PR's already quite large.

backend/remote-state/azure/arm_client.go

backend/remote-state/azure/backend.go

tombuildsstuff · 2018-11-21T15:05:09Z

Tests prior to updating the names:

backend/remote-state/azure/arm_client.go

backend/remote-state/azure/helpers_test.go

- updating to v21.3.0 of github.com/Azure/azure-sdk-for-go - updating to v10.15.4 of github.com/Azure/go-autorest - vendoring github.com/hashicorp/go-azure-helpers @ 0.1.1

- refactoring the backend to use a shared client via the new auth package - adding tests covering both Service Principal and Access Key auth - support for authenticating using a proxy - rewriting the backend documentation to include examples of both authentication types

tombuildsstuff · 2018-11-21T17:17:20Z

Now that we're testing both Access Key and Service Principal authentication explicitly - the failing test has been duplicated (which is intentional) - but this otherwise passes on Azure Public & Azure Germany:

The failing tests in question (which will be fixed in the follow up PR):

Overall LGTM except the log level thingy.

backend/remote-state/azure/sender.go

radeksimko · 2018-11-21T18:05:00Z

Also this certainly needs review from someone more familiar with Azure than me.

LGTM @tombuildsstuff 👍
