[Starlingx-discuss] [Release] [Build] Preparation and discussion about StarlingX release 2.0

[Zvonar, Bill]

Ada/Numan - FYI re: build frequency...

According the build team notes from last week's meeting [0], they will do 2 builds daily during the 4 week (RC1 - Release) period.

Hi all - yesterday's sanity was green, so we'll go ahead with the plan below (assuming Dean & Scott haven't run into any roadblocks).

From the meeting just now, Scott & Dean agreed that they can base the branch off of a SHA, so there is no need for a freeze.

They will finish some script changes for this (thanks guys) and, assuming Monday's sanity is green, will start creating the branch on Tuesday.

After the sanity on the RC1 branch is done, we'll announce that the branch is ready to use.

More details here and at [0] on the modified sequence... 

1 Start (no freeze required since we're branching from a SHA, not from Head)
    - on Tuesday 
    - Dean will start at ~9:30 his time (CDT) (10:30 EDT)
    - assuming sanity is Green
    - Dean will branch from the SHA for that sanity's build 2. Scott/Dean create RC1 branch and make required build changes.
    - Dean will make sure he's able to do the SHA thing 
    - this will be based on Monday's sanity, which will be based on the commits up to Sunday evening 
    - i.e. UTC 0130 am Monday https://www.timeanddate.com/worldclock/fixedtime.html?iso=20190805T0130
3. Scott triggers RC1 build, both ISO and Docker images.
    - Scott has a few script changes to do, will work to knock those off today 
    - we agreed on these build paths
    - Release path
            .../starlingx/release/2.0.##/centos
            .../starlingx/release/2.0/2.0.##/centos
    - RC path
            .../starlingx/rc/2.0/centos/timestamp
4. Ada's team runs sanity and confirm RC1 build passes sanity.
5. Release Team announces that the RC1 branch is now available. 

Note: Developers push changes to master and for Medium & High priority LPs also cherry pick their commit to the RC1 branch.

I ran a dry-run of the branching process this morning using the following:

Branch: r/stx.2.0
Tag: v2.0.0.rc0

Tagging the branch point makes it easier later to pull a list of changes for the next RC or the release tag...

I did find a couple of tweaks required in the branch-stx.sh script to account for the OpenDev change and only branching the Gerrit repos:

The wiki pages [0] and [1] have been updated to match my current understanding (above) of the release naming and process.
