From 4db745b8dddb024440a278a0af9f06e587e45902 Mon Sep 17 00:00:00 2001 From: Frank Louwers Date: Thu, 27 Nov 2025 23:34:31 +0100 Subject: [PATCH 1/6] feat(core): add CLI provider authentication support Add new cliauth package that enables SDK applications to use STACKIT CLI provider credentials without direct CLI dependency. This implementation supports: - Reading credentials from system keyring or file fallback - Automatic OAuth2 token refresh with configurable endpoints - Multiple CLI profile support with profile resolution - Bidirectional credential sync (writeback after refresh) - Thread-safe RoundTripper implementation for HTTP clients - Background token refresh with context-based lifecycle management Storage locations: - System Keyring (macOS Keychain, Linux Secret Service, Windows Credential Manager) - File fallback: ~/.stackit/cli-api-auth-storage.txt --- core/cliauth/background_refresh.go | 168 ++++++++++++ core/cliauth/credentials.go | 400 +++++++++++++++++++++++++++++ core/cliauth/doc.go | 101 ++++++++ core/cliauth/flow.go | 191 ++++++++++++++ core/cliauth/token_refresh.go | 154 +++++++++++ core/go.mod | 8 + core/go.sum | 22 ++ 7 files changed, 1044 insertions(+) create mode 100644 core/cliauth/background_refresh.go create mode 100644 core/cliauth/credentials.go create mode 100644 core/cliauth/doc.go create mode 100644 core/cliauth/flow.go create mode 100644 core/cliauth/token_refresh.go diff --git a/core/cliauth/background_refresh.go b/core/cliauth/background_refresh.go new file mode 100644 index 000000000..b2caa1d90 --- /dev/null +++ b/core/cliauth/background_refresh.go @@ -0,0 +1,168 @@ +package cliauth + +import ( + "fmt" + "os" + "time" +) + +var ( + // Start refresh attempts this duration before token expiration + defaultTimeStartBeforeTokenExpiration = 5 * time.Minute + // Check context cancellation this frequently while waiting + defaultTimeBetweenContextCheck = time.Second + // Retry interval on refresh failures + defaultTimeBetweenTries = 2 * time.Minute +) + +// continuousRefreshToken continuously refreshes the CLI provider token in the background. +// It monitors token expiration and automatically refreshes before the token expires. +// +// The goroutine terminates when: +// -

25b6b99bd648fce58d40fe21b96ab65db1247cbf Mon Sep 17 00:00:00 2001 From: Frank Louwers Date: Thu, 27 Nov 2025 23:39:15 +0100 Subject: [PATCH 4/6] fix(core): update CLI auth tests to match implementation Fix test expectations to match the actual implementation: - Update keyring service name from 'stackit-cli-provider' to 'stackit-cli-api' - Update file paths from 'cli-provider-auth-storage.txt' to 'cli-api-auth-storage.txt' - Rewrite config tests to match the actual API (profile string instead of provider object) - Fix helper functions in test files All tests now pass successfully. --- core/cliauth/credentials_test.go | 14 +- core/cliauth/flow_test.go | 2 +- core/config/cli_auth_test.go | 278 ++++++++++++------------------- 3 files changed, 115
