That means fail fast so that we can improve before we reach the public - -2) Reduce the time to market to minimum, by streamlining the release process. - That means a lot of testing, a lot of consistency checks, a lot of validations - -3) Generated artifacts consistency. We should not allow broken software to reach the public. - When this happens, it's embarassing and we struggle to eliminate it. - -4) We are an innovative company, so we love to automate :) - - -Having said that, here's a brief introduction to Netdata's improved CI/CD pipeline with Travis. -Our CI/CD lifecycle contains three different execution entry points: -1) A user opens a pull request to netdata/master: Travis will run a pipeline on the branch under that PR -2) A merge or commit happens on netdata/master. This will trigger travis to run, but we have two distinct cases in this scenario: - a) A user merges a pull request to netdata/master: Travis will run on master, after the merge. - b) A user runs a commit/merge with a special keyword (mentioned later). - This triggers a release for either minor, major or release candidate versions, depending the keyword -3) A scheduled job runs on master once per day: Travis will run on master at the scheduled interval - -To accommodate all three entry points our CI/CD workflow has a set of steps that run on all three entry points. -Once all these steps are successfull, then our pipeline executes another subset of steps for entry points 2 and 3. -In travis terms the "steps" are "Stages" and within each stage we execute a set of activities called "jobs" in travis. - -### Always run: Stages that running on all three execution entry points - -## Code quality, linting, syntax, code style -At this early stage we iterate through a set of basic quality control checks: -- Shell checking: Run linters for our various BASH scripts -- Checksum validators: Run validators to ensure our installers and documentation are in sync -- Dashboard validator: We provide a pre-generated dashboard.js script file that we need to make sure its up to date. We validate that. - -## Build process -At this stage, basically, we build :-) -We do a baseline check of our build artifacts to guarantee they are not broken -Briefly our activities include: -- Verify docker builds successfully -- Run the standard Netdata installer, to make sure we build & run properly -- Do the same through 'make dist', as this is our stable channel for our kickstart files - -## Artifacts validation -At this point we know our software is building, we need to go through the a set of checks, to guarantee -that our product meets certain epxectations. At the current stage, we are focusing on basic capabilities -like installing in different distributions, running the full lifecycle of install-run-update-install and so on. -We are still working on enriching this with more and more use cases, to get us closer to achieving full stability of our software. -Briefly we currently evaluate the following activities: -- Basic software unit testing -- Non containerized build and install on ubuntu 14.04 -- Non containerized build and install on ubuntu 18.04 -- Running the full Netdata lifecycle (install, update, uninstall) on ubuntu 18.04 -- Build and install on CentOS 6 -- Build and install on CentOS 7 -(More to come) - -### Nightly operations: Stages that run daily under cronjob -The nightly stages are related to the daily nightly activities, that produce our daily latest releases. -We also maintain a couple of cronjobs that run during the night to provide us with deeper insights, -like for example coverity scanning or extended kickstart checksum checks - -## Nightly operations -At this stage we run scheduled jobs and execute the nightly changelog generator, coverity scans, -labeler for our issues and extended kickstart files checksum validations. - -## Nightly release -During this stage we are building and publishing latest docker images, prepare the nightly artifacts -and deploy them (the artifacts) to our google cloud service provider. - - -### Publishing -Publishing is responsible for executing the major/minor/patch releases and is separated -in two stages: packaging preparation process and publishing. - -## Packaging for release -During packaging we are preparing the release changelog information and run the labeler. - -## Publish for release -The publishing stage is the most complex part in publishing. This is the stage were we generate and publish docker images, -prepare the release artifacts and get ready with the release draft. - -### Package Management workflows -As part of our goal to provide the best support to our customers, we have created a set of CI workflows to automatically produce -DEB and RPM for multiple distributions. These workflows are implemented under the templated stages '_DEB_TEMPLATE' and '_RPM_TEMPLATE'. -We currently plan to actively support the following Operating Systems, with a plan to further expand this list following our users needs. - -### Operating systems supported -The following distributions are supported -- Debian versions - - Buster (TBD - not released yet, check [debian releases](https://www.debian.org/releases/) for details) - - Stretch - - Jessie - - Wheezy - -- Ubuntu versions - - Disco - - Cosmic - - Bionic - - artful - -- Enterprise Linux versions (Covers Redhat, CentOS, and Amazon Linux with version 6) - - Version 8 (TBD) - - Version 7 - - Version 6 - -- Fedora versions - - Version 31 (TBD) - - Version 30 - - Version 29 - - Version 28 - -- OpenSuSE versions - - 15.1 - - 15.0 - -- Gentoo distributions - - TBD - -### Architectures supported -We plan to support amd64, x86 and arm64 architectures. As of June 2019 only amd64 and x86 will become available, as we are still working on solving issues with the architecture. - -The Package deployment can be triggered manually by executing an empty commit with the following message pattern: `[Package PACKAGE_TYPE PACKAGE_ARCH] DESCRIBE_THE_REASONING_HERE`. -Travis Yaml configuration allows the user to combine package type and architecture as necessary to regenerate the current stable release (For example tag v1.15.0 as of 4th of May 2019) -Sample patterns to trigger building of packages for all amd64 supported architecture: -- '[Package amd64 RPM]': Build & publish all amd64 available RPM packages -- '[Package amd64 DEB]': Build & publish all amd64 available DEB packages |
