The build workflow builds components declared in an input manifest from source, or downloads previously built artifacts, in order. All manifests for current releases are in manifests. Here are some examples.
name | description |
---|---|
opensearch-1.0.0.yml | Manifest to reproduce 1.0.0 build. |
opensearch-1.0.0-maven.yml | One-time manifest to build maven artifacts for 1.0 from tags. |
opensearch-1.1.0.yml | Manifest for 1.1.0, the current version. |
opensearch-1.1.1.yml | Manifest for 1.1.1, a patch release. |
opensearch-1.2.0.yml | Manifest for 1.2.0, the next version. |
opensearch-2.0.0.yml | Manifest for 2.0.0, the next major version of OpenSearch. |
opensearch-dashboards-1.1.0.yml | Manifest for 1.1.0, the next version of OpenSearch Dashboards. |
The following example builds a snapshot version of OpenSearch 1.2.0.
./build.sh manifests/1.2.0/opensearch-1.2.0.yml --snapshot
While the following builds a snapshot version of OpenSearch-Dashboards 1.2.0.
./build.sh manifests/1.2.0/opensearch-dashboards-1.2.0.yml --snapshot
The OpenSearch repo is built first, followed by common-utils, and all declared plugin repositories. These dependencies are published to maven local under ~/.m2
, and subsequent project builds pick those up.
The OpenSearch Dashboards repo is built first, followed by all declared plugin repositories.
All final output is placed into a builds/opensearch
and builds/opensearch-dashboards
folder respectively, along with a build output manifest.yml
that contains output details.
The build order first publishes OpenSearch
followed by common-utils
, and publishes these artifacts to maven local so that they are available for each component. In order to ensure that the same versions are used, a -Dopensearch.version
flag is provided to each component's build script that defines which version the component should build against.
The build order first pulls down OpenSearch-Dashboards
and then utilizes it to build other components. Currently, building plugins requires having the core repository built first to bootstrap and build the modules utilized by plugins.
To build components we rely on a common entry-point in the form of a build.sh
script. Within each build script components have the option to place artifacts in a set of directories to be picked up and published on their behalf. These are as follows.
name | description |
---|---|
/dist | Include any distributions, e.g. opensearch or opensearch-dashboards min tarball. |
/maven | Include any publications that should be pushed to maven |
/plugins | Where a plugin zip should be placed. If included it will be installed during bundle assembly. |
/core-plugins | Where plugins shipped from https://github.com/opensearch-project/OpenSearch should be placed |
/bundle | Where the min bundle should be placed when built from https://github.com/opensearch-project/OpenSearch |
/libs | Where any additional libs should be placed that are required during bundle assembly |
The following options are available in build.sh
.
name | description |
---|---|
-s, --snapshot | Build a snapshot instead of a release artifact, default is false . |
-a, --architecture | Specify architecture to build, default is architecture of build system. |
-d, --distribution | Specify distribution to build, default is tar . |
-p, --platform | Specify platform to build, default is platform of build system. |
--component [name ...] | Rebuild a subset of components by name, e.g. --component common-utils job-scheduler . |
--keep | Do not delete the temporary working directory on both success or error. |
--continue-on-error | Do not fail the bundle build on plugin component failure. |
-l, --lock | Generate a stable reference manifest. |
-v, --verbose | Show more verbose output. |
Each component build relies on a build.sh
script that is used to prepare bundle artifacts for a particular bundle version that takes two arguments: version and target architecture. By default the tool will look for a script in scripts/components, then in the checked-out repository in scripts/build.sh
, then default to a Gradle build implemented in scripts/default/opensearch/build.sh.
Builds can automatically generate a manifest.lock
file with stable git references (commit IDs) and build options (platform, architecture and snapshot) by specifying --lock
. The output can then be reused as input manifest after checking against a collection of prior builds.
MANIFEST=manifests/1.2.0/opensearch-1.2.0.yml
SHAS=shas
./build.sh --lock $MANIFEST # generates opensearch-1.2.0.yml.lock
MANIFEST_SHA=$(sha1sum $MANIFEST.lock | cut -f1 -d' ') # generate a checksum of the stable manifest
if test -f "$SHAS/$MANIFEST_SHA.lock"; then
echo "Skipping $MANIFEST_SHA"
else
./build.sh $MANIFEST.lock # rebuild using stable references in .lock
mkdir -p $SHAS
cp $MANIFEST.lock $SHAS/$MANIFEST_SHA.lock # save the stable reference manifest
fi
The Jenkins workflows in this repository can use this mechanism to avoid rebuilding all of OpenSearch and OpenSearch Dashboards unnecessarily.
