The OpenSearch project releases as versioned distributions of OpenSearch, OpenSearch Dashboards, and the OpenSearch plugins. It follows semantic versioning. Software, such as Data Prepper, clients, and the Logstash output plugin, are versioned independently of the OpenSearch Project. They also may have independent releases from the main project distributions. The OpenSearch Project may also release software under alpha, beta, release candidate, and generally available labels. The definition of when to use these labels is derived from the Wikipedia page on Software release lifecycle. Below is the definition of when to use each label.
Release labels:
- Alpha - The code is released with instructions to build. Built distributions of the software may not be available. Some features many not be complete. Additional testing and developement work is planned. Distributions will be postfixed with
-alphaXwhere "X" is the number of the alpha version (e.g., "2.0-alpha1"). - Beta - Built distributions of the software are available. All features are completed. Additional testing and developement work is planned. Distributions will be postfixed with
-betaXwhere "X" is the number of the beta version (e.g., "2.0.0-beta1"). - Release Candidate - Built distributions of the software are available. All features are completed. Code is tested and minimal validation remains. At this stage the software is potentially stable and will release unless signficant bugs emerge. Distributions will be postfixed with
-rcXwhere "X" is the number of the release candidate version (e.g., "2.0.0-rc1"). - Generally Available - Built distributions of the software are available. All features are completed and documented. All testing is completed. Distributions for generally available versions are not postfixed with an additional label (e.g., "2.0.0").
Each new OpenSearch release process starts when any one component increments a version, typically on the main branch. For example, OpenSearch#1192 incremented the version to 2.0. The version check automation workflow will notice this change or it can be triggered manually, and make a pull request (e.g. opensearch-build#514) that adds a new manifest (e.g. opensearch-2.0.0.yml. After that's merged, a GitHub issue is automatically opened by this workflow to make a new release using this release template (e.g. opensearch-build#566). Existing and new components (re)onboard into every release by submitting pull requests to each version's manifest.
Plugin owners can follow the Onboarding Process to onboard their plugins to the release process.
The distribution workflow builds a complete OpenSearch and OpenSearch Dashboards distribution from source. You can currently build 1.0, 1.1, 1.1-SNAPSHOT and 1.2 versions. This system performs a top-down build of all components required for a specific OpenSearch and OpenSearch Dashboards release, then assembles a distribution. The input to the system is a manifest that defines the order in which components should be built. All manifests for our current releases are here.
./build.sh manifests/1.3.0/opensearch-1.3.0.yml This builds OpenSearch 1.3.0 from source, placing the output into ./builds/opensearch.
See build workflow for more information.
./assemble.sh builds/opensearch/manifest.ymlThe assembling step takes output from the build step, installs plugins, and assembles a full distribition into the dist folder.
See assemble workflow for more information.
A patch release contains output from previous versions mixed with new source code. Manifests can mix such references. See opensearch-1.1.1.yml for an example.
OpenSearch is often released with changes in opensearch-min, and no changes to plugins other than a version bump. This can be performed by a solo Engineer following a cookbook. See also opensearch-build#1375 which aims to automate incrementing versions for the next development iteration.
Snapshots for OpenSearch core/min can be downloaded and used in CI's, local development, etc using below links:
Linux:
https://artifacts.opensearch.org/snapshots/core/opensearch/<version>-SNAPSHOT/opensearch-min-<version>-SNAPSHOT-linux-x64-latest.tar.gz
Macos:
https://artifacts.opensearch.org/snapshots/core/opensearch/<version>-SNAPSHOT/opensearch-min-<version>-SNAPSHOT-darwin-x64-latest.tar.gz
Windows:
https://artifacts.opensearch.org/snapshots/core/opensearch/<version>-SNAPSHOT/opensearch-min-<version>-SNAPSHOT-windows-x64-latest.zip
We build, assemble, and test our artifacts on docker containers. We provide docker files in docker/ci folder, and images on staging docker hub repositories. All Jenkins pipelines can be found in jenkins. Jenkins itself is in the process of being made public and its CDK open-sourced.
See jenkins and docker for more information.
The distribution url and the build output manifest include a Jenkins auto-incremented build number. For example, the manifest from OpenSearch build 5905 contains the following.
build:
name: OpenSearch
version: 2.2.0
platform: linux
architecture: x64
distribution: rpm
id: '5905'Use the latest keyword in the URL to obtain the latest build for a given version. For example https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/2.2.0/latest/linux/x64/rpm/dist/opensearch/manifest.yml redirects to build 5905 at the time of writing this.
The latest keyword is resolved to a specific build number by checking an index.json file. This file has contents such as this.
{"latest":"5905"}
The file is updated when a distribution build job is completed for the given product and version (or is created when such distribution job succeeds for the first time). Since one distribution build job consists of multiple stages for different combinations of distribution type, platform and architecture, the index.json is only modified once all stages succeed. With this said, the latest url only works when the distribution build job succeeds at least once for the given product and version.
The resolution logic is implemented in the CloudFront url rewriter.
The TTL (time to live) is set to 5 mins which means that the latest url may need up to 5 mins to get new contents after index.json is updated.
All the artifacts accessible through the regular distribution url can be accessed by the latest url. This includes both OpenSearch Core, OpenSearch Dashboards Core and their plugins.
For example, you can download the latest .tar.gz distribution build of OpenSearch 2.2.0 directly at https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/2.2.0/latest/linux/x64/tar/dist/opensearch/opensearch-2.2.0-linux-x64.tar.gz, without having to first download and parse the complete build manifest.
For plugin artifacts, you can also use the latest keyword to get the latest plugin artifacts with a known version. E.g. in order to get performance-analyzer x64 tarball artifacts for 2.1.0, you can obtain it with link https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/2.1.0/latest/linux/x64/tar/builds/opensearch/plugins/opensearch-performance-analyzer-2.1.0.0.zip, which will redirect you to https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/2.1.0/5757/linux/x64/tar/builds/opensearch/plugins/opensearch-performance-analyzer-2.1.0.0.zip.
For bundled artifacts, here are some examples for LINUX and Windows:
- Linux Tar:
https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/2.4.0/latest/linux/x64/tar/dist/opensearch/opensearch-2.4.0-linux-x64.tar.gz - Windows Zip:
https://ci.opensearch.org/ci/dbc/distribution-build-opensearch/2.4.0/latest/windows/x64/zip/dist/opensearch/opensearch-2.4.0-windows-x64.zip
Tests the OpenSearch distribution, including integration, backwards-compatibility and performance tests.
./test.sh <test-type> <test-manifest-path> <path>See src/test_workflow for more information.
Workflow to check if the release notes exists or not and shows the latest commit for OpenSearch and Dashboard distributions.
To run:
./release_notes.sh check manifests/2.2.0/opensearch-2.2.0.yml --date 2022-07-26See src/release_notes_workflow for more information.
For all types of signing within OpenSearch project we use opensearch-signer-client (in progress of being open-sourced) which is a wrapper around internal signing system and is only available for authenticated users. The input requires a path to the build manifest or directory containing all the artifacts or a single artifact.
Usage:
./sign.sh builds/opensearch/manifest.ymlThe tool currently supports following platforms for signing.
Anything can be signed using PGP signing eg: tarball, any type of file, etc. A .sig file will be returned containing the signature. OpenSearch and OpenSearch dashboards distributions, components such as data prepper, etc as well as maven artifacts are signed using PGP signing. See this page for how to verify signatures.
Windows signing can be used to sign windows executables such as .msi, .msp, .msm, .cab, .dll, .exe, .appx, .appxbundle, .msix, .msixbundle, .sys, .vxd, .ps1, .psm1, and any PE file that is supported by Signtool.exe. Various windows artifacts such as SQL OBDC, opensearch-cli, etc are signed using this method. Windows code signing uses EV (Extended Validated) code signing certificates.
| Types of signing/Details | Digest | Cipher | Key Size |
|---|---|---|---|
| PGP | SHA1 | AES-128 | 2048 |
| Windows | SHA256 | RSA | |
| RPM | SHA512 | RSA | 4096 |
RPM artifacts are signed via a legacy shell script which uses a macros template. See this commit for more information and this issue to add RPM artifact signing functionality to the above signing system. Currently we are only signing OpenSearch and OpenSearch dashboards RPM distributions using this method.
See src/sign_workflow for more information.
The Linux / Windows release is managed by a team at Amazon following this release template (e.g. opensearch-build#2649).
The FreeBSD ports and packages for OpenSearch are managed by a community OpenSearch Team at FreeBSD. When a new release is rolled out, this team will update the port and commit it to the FreeBSD ports tree. Anybody is welcome to help the team by providing patches for upgrading the ports following the FreeBSD Porter's Handbook instructions.
At this moment there's no official MacOS distribution. However, this project does support building and assembling OpenSearch for MacOS. See opensearch-build#37 and #38 for more details.
The checkout workflow checks out source code for a given manifest for further examination.
./checkout.sh manifests/1.3.0/opensearch-1.3.0.ymlSee src/checkout_workflow for more information.
You can perform cross-platform builds. For example, build and assemble a Windows distribution on MacOS.
export JAVA_HOME=$(/usr/libexec/java_home) # required by OpenSearch install-plugin during assemble
./build.sh manifests/1.3.0/opensearch-1.3.0.yml --snapshot --platform windows
./assemble.sh builds/opensearch/manifest.ymlThis will produce dist/opensearch-1.3.0-SNAPSHOT-windows-x64.zip on Linux and MacOS.
This workflow runs sanity checks on every component present in the bundle, executed as part of the manifests workflow in this repository. It ensures that the component GitHub repositories are correct and versions in those components match the OpenSearch version.
The following example sanity-checks components in the the OpenSearch 1.3.0 manifest.
./ci.sh manifests/1.3.0/opensearch-1.3.0.yml --snapshotSee src/ci_workflow for more information.
The manifests workflow reacts to version increments in OpenSearch and its components by extracting Gradle properties from project branches. When a new version is found, a new input manifest is added to manifests, and a pull request is opened (e.g. opensearch-build#491).
Show information about existing manifests.
./manifests.sh listCheck for updates and create any new manifests.
./manifests.sh updateSee src/manifests_workflow for more information.
Storage and access roles for the OpenSearch release process are codified in a CDK project.
