+========================================== + +Introduction +------------- + +Problem Statement: +^^^^^^^^^^^^^^^^^^^ + +OPNFV will use many upstream open source projects to create the reference platform. +All these projects are developed and tested independently and in many cases, +not have use cases of other projects in mind. +Therefore it is to be expected that integration of these projects probably will unveil some gaps in functionality, +since testing the OPNFV use cases needs the interworking of many upstream projects. +Thus this integration work will bring major benefit to the community. + +Therefore the goal of the CI project – Octopus – is to quickly provide +prototype integration of a first set of upstream projects. +Step by step this later will be evolved to a full blown development environment with +automated test and verification as a continuous integration environment, supporting both, +the parallel evolutionary work in the upstream projects, and the improvement of NFV support in this reference platform. + +Summary +^^^^^^^^ + +The CI project provides the starting point for all OPNFV development activities. +It starts by integrating stable versions of basic upstream projects, +and from there creates a full development environment for OPNFV including automatic builds and basic verification. +This is a very complex task and therefore needs a step by step approach. +At the same time it is urgent to have a basic environment in place very soon. + +* **Create a hierarchical build environment** for the same integrated upstream projects as "getstarted", +that uses the build tools as defined by each of the upstream projects and combines them. +This allows development and verification in OPNFV collaborative projects. + +* **Implement automatic build process on central servers** - Provide automation and periodic builds + +* **Execute the continuous automated builds and basic verification** diff --git

+What is Artifact Repository +--------------------------- + +An Artifact Repository is akin to what Subversion is to source code, i.e. +it is a way of versioning artifacts produced by build systems, CI, and so on. [1] + +Why Artifact Repository is Needed +--------------------------------- + +Since many developers check their source code into the GIT repository it may seem natural +to just place the files you've built into the repo too. +This can work okay for a single developer working on a project over the weekends +but with a team working on many components that need to be tested and integrated, this won't scale. + +The way git works, no revision of any file is ever lost. +So if you ever check in a big file, the repository will always contain it, +and a git clone will be that much slower for every clone from that point onward. + +The golden rule of revision control systems applies: +*check in your build scripts, not your build products*. + +Unfortunately, it only takes one person to start doing this and we end up with huge repositories. +Please don't do this. It will make your computers sad. +Thankfully, Gerrit and code review systems are a massive disincentive to doing this. + +You definitely need to avoid storing binary images in git. This is what artifact repositories are for. [2] + +A “centralized image repository” is needed that can store multiple versions of various virtual machines +and have something like /latest pointing to the newest uploaded image. +It could be a simple nginx server that stores the output images from any jenkins job if it's successful, for instance. + +OPNFV Artifact Repository +========================= + +What is used as Artifact Repository for OPNFV +--------------------------------------------- + +Setting up, hosting, and operating an artifact repository on OPNFV Infrastructure +in Linux Foundation (LF) environment requires too much storage space. +It is also not a straightforward undertaking to have robust Artifact Repository and provide 24/7 support. + +OPNFV Project decided to use **Google Cloud Storage** as OPNFV Artifact Repository due to reasons summarized above. [3] + +Usage of Artifact Repository in OPNFV CI +---------------------------------------- + +Binaries/packages that are produced by OPNFV Continuous Integration (CI) are deployed/uploaded +to Artifact Repository making it possible to reuse artifacts during later stages of OPNFV CI. +Stored artifacts can be consumed by individual developers/organizations as well. + +In OPNFV, we generally produce PDF, ISO and store them on OPNFV Artifact Repository. + +OPNFV Artifact Repository Web Interface +---------------------------------------- + +OPNFV Artifact Repository is accessible via link http://artifacts.opnfv.org/. + +A proxy has been set up by LF for the community members located in countries with access restrictions to Google http://build.opnfv.org/artifacts/. + +Access Rights to OPNFV Artifact Repository +========================================== + +As summarized in previous sections, OPNFV uses Google Cloud Storage as Artifact Repository. +By default, everyone has read access to it and artifacts can be fetched/downloaded using browser, +a curl-like command line HTTP client, or gsutil. + +Write access to Artifact Repository is given per request basis and all the requests +must go through `LF Helpdesk `_ with an explanation +regarding the purpose of write access. +Once you are given write access, you can read corresponding section to store artifacts on OPNFV Artifact Repository. + +How to Use OPNFV Artifact Repository +==================================== + +There are 3 basic scenarios to use OPNFV Artifact repository. + +* browsing artifacts +* downloading artifacts +* uploading artifacts + +Please see corresponding sections regarding how to do these. + +How to Browse Artifacts Stored on OPNFV Artifact Repository +----------------------------------------------------------- + +You can browse stored artifacts using + +* **Web Browser**: By navigating to the address `OPNFV Artifact Storage `_. + +* **Command Line HTTP-client** + ``curl -o http://artifacts.opnfv.org`` + + Example: + + ``curl -o opnfv-artifact-repo.html http://artifacts.opnfv.org`` + +* **Google Storage Util (gsutil)** + ``gsutil ls gs://artifacts.opnfv.org/`` + + Example: + + ``gsutil ls gs://artifacts.opnfv.org/octopus`` + +How to Download Artifacts from OPNFV Artifact Repository +-------------------------------------------------------- + +You can download stored artifacts using + +* **Web Browser**: By navigating to the address `OPNFV Artifact Storage `_ and clicking the link of the artifact you want to download. + +* **Command Line HTTP-client** + ``curl -o http://artifacts.opnfv.org/`` + + Example: + + ``curl -o main.pdf http://artifacts.opnfv.org/octopus/docs/release/main.pdf`` + +* **Google Storage Util (gsutil)** + ``gsutil cp gs://artifacts.opnfv.org/ `` + + Example: + + ``gsutil cp gs://artifacts.opnfv.org/octopus/docs/release/main.pdf main.pdf`` + +How to Upload Artifacts to OPNFV Artifact Repository +---------------------------------------------------- + +As explained in previous sections, you need to get write access for OPNFV Artifact Repository +in order to upload artifacts. + +Apart from write access, you also need to have Google account and have the +Google Cloud Storage utility, **gsutil**, installed on your computer. + +Install and Configure gsutil +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Please follow steps listed below. + +1.

ones can be installed when requirements arise. + +The Jenkins jobs are defined by Jenkins Job Builder(JJB) in human readable YAML format. +The jobs defined are the key points of CI pipeline. +To make clear how the jobs in pipeline run to complete the build, deploy, test works, +you can refer to https://wiki.opnfv.org/octopus/pipelines. +Moreover, to start your own job in Jenkins, +you can write a JJB under the guide of https://wiki.opnfv.org/octopus/jenkins_wow. + +Artifact Repository +------------------- + +An artifact repository is a collection of binary software artifacts +and metadata stored in a defined directory structure, +it is a kin to what subversion is to source code, i.e., +it is a way of versioning artifacts produced by build systems, CI, and so on. +At this moment, since

These should be reviewed in advance of disclosure by committers and stable-maint. At the time of coordinated public disclosure, the fix is proposed simultaneously to master and the stable branches and immediately approved. - -Processes ---------- - -Proposing fixes -~~~~~~~~~~~~~~~ - -Anyone can propose a cherry-pick to the stable-maint team. - -One way is that if a bugfix on master looks like a good candidate for backporting - e.g. if it's a significant bug with the revious release - then just nominating the bug for Arno maintenance will bring it to the attention of the maintainers. - -If you don't have the appropriate permissions to nominate the bug, then send an email via the user list. - -The best way to get the patch merged in timely manner is to send it backported by yourself. To do so, you may try to use "Cherry Pick To" button in Gerrit UI for the original patch in master. Gerrit will take care of creating a new review, modifying commit message to include 'cherry-picked from ' line etc. - -If the patch you're proposing will not cherry-pick cleanly, you can help by resolving the conflicts yourself and proposing the resulting patch. Please keep Conflicts lines in the commit message to help reviewers! You can use git-review to propose a change to the stable branch with:: - - $> git log (find out the commit id of the patch that you want to backport from "git log" output) - $> git checkout stable/arno - $> git cherry-pick -x $master_commit_d - $> git review stable/arno - -Note: cherry-pick -x option includes 'cherry-picked from ' line in the commit message which is required to avoid Gerrit bug - -Failing all that, just ping one of the team and mention that you think the bug/commit is a good candidate. - -Change-Ids -~~~~~~~~~~ - -When cherry-picking a commit, keep the original Change-Id and gerrit will show a separate review for the stable branch while still allowing you to use the Change-Id to see all the reviews associated with it. - -Hint: Change-Id line must be in the last paragraph. Conflicts in the backport: add a new paragraph, creating a new Change-Id but you can avoid that by moving conflicts above the paragraph with Change-Id line or removing empty lines to make a single paragraph. - -Email Notifications -~~~~~~~~~~~~~~~~~~~ - -If you want to be notified of these patches you can create a watch on this screen: -https://gerrit.opnfv.org/gerrit/#/settings/projects -click "Watched Projects" - -Project Name: All-Projects - -Only If: branch:stable/arno - -Then check the "Email Notifications - New Changes" checkbox.

It is in the responsibility of each project how to select those committers (e.g. vote in the team). - -The group of these committers here are sometimes called the "stable branch maintenance team" or "stable-mtc" without this being necessarily a team with own organization. - -Stable branch management -~~~~~~~~~~~~~~~~~~~~~~~~ - -Stable branches are less exercised than master branches, and they may get broken by external events. - -Therefore a group of committers, the "stable branch maintenance team" (stable-mtc) is tasked with specific stable branch support, making sure the branch stays in good shape and remains usable at all times. They monitor periodic jobs failures and enlist the help of others in order to fix the branches in case of breakage. They should also raise flags if for some reason they are blocked and don't receive enough support, in which case early abandon of the branch will be considered. - -The stable-mtc is responsible for the enforcement of the Stable Branch policy. Initially it is composed of a release manager and at least one committer of each of the participating projects and will have similar organization and rights as OPNFV project teams. It will be granting exceptions for all questionable backports raised by projects, providing backports reviews help everywhere, and educating projects members on the stable branch policy. - -The stable-mtc will propose to TSC to decide on point releases from the stable branch. Preparation of the point release will be described in a second step. The stable-mtc can also propose to TSC to decide to abandon maintenance of the release. - -When a new OPNFV version is released, a stable-mtc team for that project will start. At that time, the earlier maintenance version will go to a phase with less support. Details will be defined later. - -Joining the team -~~~~~~~~~~~~~~~~ - -Existing committers are greatly encouraged to join the stable-mtc in order to help with reviewing backports, judging their appropriateness for the stable branch and approving them. - -We're really keen to add more folks to the stable Arno stable-mtc to help out with reviews. - -All you really need is some time and the ability to apply the "safe source of high impact fixes" and "must be fixed on master first" policies. It mostly comes down to having a good sense of the risk vs benefit of applying a backport to the branch. - -If you'd like to join the team, you can start by simply [+-]1ing stable branch reviews. It's best if you can add some brief thoughts to your review on why you think the fix is suitable for stable so that we know how you're applying the policy. - -Same as in normal OPNFV projects, stable-mtc team will use committer votes for some decisions like proposing a new point release to TSC. -- cgit 1.2.3-korg
