#+ NAME
#+ $PROG - Kubernetes Release Tool
#+
#+ SYNOPSIS
#+ $PROG <branch> [--yes] [--nomock] [--rc] [--official]
#+ [--clean] [--stage] [--github-release-draft]
#+ [--buildversion=<jenkins build version>]
#+ [--gcrio_path=<full gcr.io path>]
#+ [--basedir=<alt base work dir>]
#+ [--security_layer=/path/to/pointer/to/script]
#+ [--exclude-suites="<suite> ..."]
#+ [--build-at-head]
#+ [--prebuild] [--buildonly]
#+ [--mailto=<email1>,<email2>] [--gcb]
#+ [--tmpdir=</alt/tmp>]
#+ $PROG [--helpshort|--usage|-?]
#+ $PROG [--help|-man]
#+
#+ DESCRIPTION
#+ $PROG produces Kubernetes releases.
#+
#+ Driven by the named source <branch> and an optional [--rc] or
#+ [--official] flag, $PROG determines what needs to be released
#+ and calculates the version.
#+
#+ [--buildversion=] will override the automatic check for a build version
#+ Mostly used for testing as a way to re-use a known good build version.
#+
#+ What is going to be done is presented to the user and asks for
#+ confirmation before continuing.
#+
#+ All prerequisites are checked before the process begins.
#+
#+ $PROG runs in mock/dryrun mode by default. To actually execute a
#+ release, pass in the --nomock flag.
#+
#+ ++++ NEW (for 1.8+) ++++
#+ --stage writes all usual and extra artifacts to
#+ gs://$RELEASE_BUCKET/stage for later use by 'release' runs.
#+ * The 'staged' version identifier is the source JENKINS_BUILD_VERSION
#+ rather than the computed version(s) that stem from it to identify
#+ the final release artifacts. You may stage multiple source builds
#+ for potential release later
#+ * When you run a standard 'release', $PROG will look for staged bits:
#+ - LOCALLY: The complete source tree, including all commits & artifacts.
#+ - GCS: Artifacts only in
#+ gs://$RELEASE_BUCKET/stage/$JENKINS_BUILD_VERSION
#+ * This method works with both mock and --nomock INTERCHANGEABLY
#+ on the local disk. If relying on the GCS staging, be sure to use
#+ --nomock for both --stage and the real release run.
#+ * --stage also skips many of the usual release steps including many
#+ auth checks and pushes as it's primary function is to build and
#+ stage release bits and artifacts for later use.
#+
#+ Simply specify the <branch> you want to release from and follow the
#+ prompts. <branch> is one of master, release-1.2, etc. and the release
#+ is based on the <branch> value and the [--official] flag:
#+
#+ WARNING: --build-at-head bypasses any test analysis and builds directly
#+ at the HEAD Of the named branch. Mostly for testing.
#+
#+ Branch RC Official Type
#+ ------ -- -------- ----
#+ master alpha
#+ master alpha
#+ master X N/A
#+ master X N/A
#+ release-* beta
#+ release-* X release candidate
#+ release-* X official
#+
#+ NOTE: <branch> can exist already or not. If the branch doesn't exist,
#+ it will be branched from master as part of the run.
#+
#+ VALUES USED AND DISPLAYED DURING RUNS:
#+ * The RELEASE_VERSION dictionary is indexed by each of the types of
#+ releases that will be processed for a session (alpha,beta,rc,official)
#+ * RELEASE_VERSION_PRIME is the primary release version
#+ * GCRIO_PATH and RELEASE_BUCKET are the publish locations
#+ * Default GCRIO_PATH for non-mock runs utilizes a multi-region alias,
#+ k8s.gcr.io, and a single write alias, staging-k8s.gcr.io.
#+ * Switching between k8s.gcr.io and staging-k8s.gcr.io for the purposes
#+ of naming and pushing is handled by the tooling. If --gcrio_path
#+ overrides, only that name is used by the tooling in all cases.
#+
#+ A simple $USER check controls who can run in --nomock mode as ACLs
#+ restrict who can actually push bits anyway.
#+
#+ OPTIONS
#+ [--stage] - Write all artifacts to
#+ gs://$RELEASE_BUCKET/stage for later use
#+ [--yes] - Assume 'yes' to all queries
#+ [--nomock] - Complete an actual release with upstream
#+ pushes
#+ [--clean] - Force clean of previous session
#+ [--rc] - Release candidates on release branches only
#+ [--official] - Official releases on release branches only
#+ [--buildversion=ver] - Override Jenkins check and set a specific
#+ build version
#+ [--gcrio_path=] - Specify the full GCR path to use.
#+ defaults:
#+ - gcr.io/kubernetes-release-test (mock)
#+ - k8s.gcr.io for --nomock
#+ [--basedir=dir] - Specify an alternate base directory
#+ (default: /usr/local/google/$USER or $HOME/anago)
#+ [--security_layer=] - A file containing a path to a script to
#+ source/include:
#+ FLAGS_security_layer=/path/to/script
#+ Default: $HOME/.kubernetes-releaserc
#+ [--exclude-suites=] - Space separated list of CI suites regex to
#+ exclude from go/nogo criteria
#+ [--build-at-head] - Force a build at HEAD of named branch
#+ [--mailto=] - Comma-separated list of addresses to send
#+ announcement email to. Overrides default list.
#+ [--github-release-draft] - Force a github release draft for mock runs.
#+ The draft placeholder if left behind can
#+ cause issues with the real release.
#+ Users are prompted to remove draft releases,
#+ but the action to create them in the first
#+ place should be explicit.
#+ [--gcb] - Running from GCB
#+ [--tmpdir=] - Set an alternate temp dir
#+ [--prebuild] - Used during GCB to halt before building
#+ to allow switch to build container
#+ [--buildonly] - Used during GCB to halt after building
#+ to allow switch to release container
#+ [--help | -man] - display man page for this script
#+ [--usage | -?] - display in-line usage
#+
#+ EXAMPLES
#+ $PROG --yes master - Do a mock alpha release from master
#+ and don't stop/prompt
#+ $PROG release-1.1 - Do a mock beta release from release-1.1
#+ $PROG --rc release-1.1
#+ - Do a mock release candidate from release-1.1
#+ $PROG --official release-1.1
#+ - Do a mock official release from release-1.1
#+ $PROG --nomock --official release-1.1
#+ - Do an official release from release-1.1
#+ $PROG release-1.8 --stage --build-at-head
#+ - Stage a HEAD build locally and on GCS
#+ $PROG release-1.8 --nomock --build-at-head
#+ - Release the staged build
#+ (assuming HEAD hasn't changed)
