1Any Release






Update release notes
Note. Check documentation configuration and release instructions on: Create documentation for an ONAP release (ONAP project teams) 

Note. Also update the openapi info.version property with the version we are releasing for cps-core , NCMP and NCMP-inventory openapi yaml files.

Release notes available on https://docs.onap.org/projects/onap-cps/en/latest/release-notes.html

Change 123658


2

Update read-the-docs copies of openapi documentation e.g. for CPS-Core:

Code Block
titlecopy openapi.yaml
cps-rest/target/generated-sources/swaggeropenapi/openapi.yaml → docs/api/swagger/cps/openapi.yaml
cps-ncmp-rest/target/generated-sources/swaggeropenapi/openapi.yaml → docs/api/swagger/ncmp/openapi.yaml
cps-ncmp-rest/target/generated-sources/swaggeropenapi/openapi-inventory.yaml → docs/api/swagger/ncmp/openapi-inventory.yaml

For DMI-Plugin:

Code Block
titlecopy openapi.yaml
target/generated-sources/openapi/swaggeropenapi/openapi.yaml → docs/api/swagger/openapi.yaml

For CPS Temporal (no need to run mvn build for this one):

Code Block
titlecopy openapi.yml
openapi/swagger/openapi.yml → docs/_static/openapi/swagger/openapi.yml

Note 1. Run mvn clean install locally first to get required files in target subfolders

Note 2. This step can be skipped if there are no OPEN API changes

Latest (amalgamated) openapi.yaml available in read-the-docs
3

For DMI Plugin and CPS Temporal, update any CPS Core release dependency, if needed:

  • ncmp-dmi-plugin/pom.xml (cps.version property)
  • cps-temporal/pom.xml (cps.version property)
  • cps-temporal/csit/plans/default/setup.sh (STABLE_CPS_CORE_VERSION environment variable to use for integration testing)

Changes

4Go to latest Gerrit merged review of repo and comment 'stage-release'
  • maven-stage Jenkins job is triggered
  • maven-docker-stage Jenkins job is triggered
  • Maven artifacts are published to Nexus 2 autorelease repository
  • Docker images are published to Nexus 3 registry
  • Change 124884
  • Job maven-stage-master 145
  • Job maven-docker-stage-master 145


5

Add and merge 'x.y.z.yaml' file to releases folder of the repository root.

It describes the release and refers to maven-stage job previously ran.

Note: This step is ignored for CPS Temporal (no Maven artifact delivered)

Note. this file should NOT contain 'tag_release=false'

Maven artifacts are published to maven release repository
6

Add and merge 'x.y.z-container.yaml' file to releases folder of the repository root.

It describes the release and refers to maven-docker-stage job previously ran.
Set "ref" to the (full) SHA of the last git commit or the commit of the stage release
Note opinions difference what commit it should be exactly , fact is the ref. value is for  '(future) reference only' The process will complete either way and which commit exactly is bring referred too is quiet moot (not important)

Take the latest built image, retag it without the timestamp :

e.g. SO release file

Code Block
container_release_tag: '1.1.0'
...
...
containers:
    - name: 'cps-and-ncmp'
      version: '1.1.0-SNAPSHOT-20210609T102555Z'


Docker image is published to docker release repository
  • Change 124887
  • Topic CPS-728
  • To get the 'version' for the YAML file you should look up the full console log of the cps-maven-docker-stage-master job from step 4 and search for : 'Built image to Docker daemon as nexus3.onap.org:10003/onap/cps-and-ncmp'. Then you will find the correct version number with the timestamp.
7

Prepare the next drop by bumping patch version (3rd digit)

In
  1. Update all pom files
,
  1. ; set to x.y.z-SNAPSHOT by running "mvn versions:set -DnewVersion=<snapshot version>"
  2. In \version.properties, set to x.y.z
  3. Add section in \docs\release-notes.rst for next release

8

Once versions are bumped update the docker-compose file and update the latest images

  • cps-core : docker-compose.yaml
  • ncmp-dmi-plugin: docker-compose.yaml


9

Update https://gerrit.onap.org/r/q/project:oom with the release specific changes: 
Note. Use [CPS] prefix for OOM commit message

  • Update /kubernetes/cps/values.yaml with new image versions
  • Update /kubernetes/cps/resources/config/application.yml if properties need to be added or updated.

Before pushing changes to the release-specific OOM branch, it is required to push them to master first. If it can not be done, then specify a reason in the release-specific change (for example, image version number is branch specific and it is expected that it could be different in master branch and release branch).


910Only when Branching

Create the (previous) release branch in Gerrit for the version you are releasing e.g. 'istanbul'. 
Has to be done manually (e.g. here: https://gerrit.onap.org/r/admin/repos/cps,branches)  by users with committer rights. 

Note : The branch is created in ONAP gerrit. After sync happens the branch is available in NORDIX for Step-13.


https://gerrit.onap.org/r/admin/repos/cps,branches
1011In ci-management repo, configure new Jenkins jobs for the release branch by adding a new release stream to the project. e.g. https://gerrit.onap.org/r/c/ci-management/+/118868/1/jjb/cps/cps.yaml
1112

On Master branch increase Minor version of Master branch (2nd digit)

  • In pom files, set to x.y.z-SNAPSHOT by running "mvn versions:set -DnewVersion=<snapshot version>"
  • In version.properties, set to x.y.z

1213

On (previous) release (e.g. istanbul) branch:

  •  update ".gitreview" (change "defaultbranch" value)

...

  1. Decide with team if a bug should be dropped back to previous release or not, consider things like (use fix-version field in Jira to indicate this)
    1. bug was reported by user of previous release (easy decision (smile))
    2. bug exposes behavior that was not in line with acceptance criteria for a user story that was delivered in previous release
  2. Make the fix and have it merged in master branch
    1. use minimal code to avoid merge/drop back issues
    2. specific test for bug fix should be included where possible
  3. Cherry pick the fix from master branch to release branch
    1. From Gerrit:
      1. Navigate to ... / Cherry Pick
      2. Fill the form with the release branch name (honolulu) in "Cherry Pick to branch" field and click "Cherry Pick"


    2. Using local branch (to resolve cherry-pick conflicts):
      1. Create local branch from honolulu  (create branch & switch to branch)
      2. Cherry-pick commit from master branch
      3. Resolve conflicts
      4. Continue cherry-pick (git cherry-pick --continue)
      5. git push origin HEAD:refs/for/honolulu (or git review)
  4. Review patch by peers as normal
    1. Ensure that Gerrit merge requests both in master and release branches have the same Change-Id value (ex: https://gerrit.onap.org/r/q/Ia58a8dfcf427e373b24bb3be7436abf6abd55492). Then, related fixes can be easily filtered and clicking on the Change-Id from one change provides the list of all related ones.
  5. Update Release version in a separate commit if and when required
    A few bugs can be combined in one patch.
    Release notes doc should be updated too
    Typically only the 'patch' number (last digit) should be increased. See also
    1. Release Versioning Strategy (proposal for Honolulu)
    2. ONAP API Common Versioning Strategy (CVS) Guidelines
  6. Once the fix is in release branch, deliver releases artifacts from release branch as described in previous section.
