Managed Delivery supports two types of delivery artifacts: debians and Docker images.
Delivery artifacts are meant to provide Spinnaker information about:
Spinnaker needs this information to make decisions about when and how to roll out new versions as they become available. Artifacts are defined with name, type, and version strategy information.
** Warning: this is Netflix specific. Interested in contributing? Reach out to us in the #sig-spinnaker-as-code slack channel. **
All debians at Neflix are named and compared in the same way. For example, a debian might look like this:
# package name is keel keel_0.353.0-h290.ae13adb_all.deb
We compare the semantic version located after the
keel_ in this example) and before the
Debians have status information on them. A debian can have any of these statuses:
which are parsed from the semantic version of the debian.
To define a debian artifact for use with your delivery config, you’ll do something like this:
artifacts: - name: keeldemo type: deb statuses: ["RELEASE"] # This is optional reference: my-debian-artifact # optional human-readable reference to be used elsewhere in the config, defaults to artifact name
If you provide status information, you limit the possible artifacts that can be deployed to your environment. This is useful if you have a test environment that only snapshots should be deployed to, or a prod environment that only release artifacts should be deployed to.
Status information is optional. If you leave it out, versions with any status will be considered eligible for deployment into your environment.
Docker versioning is denoted by the tag value. At Netflix, there are two main ways versions are structured:
# branch-jenkinsJob.commitSha master-h5.5a52206 # semver-jenkinsJob.commitSha v1.12.1-h1159.b839a00
In order to support the different ways of doing versioning, docker artifacts have some more config options. The basic structure is like this:
artifacts: - name: emburns/spin-titus-demo type: docker reference: my-docker-artifact # optional human-readable reference to be used elsewhere in the config, defaults to artifact name tagVersionStrategy: branch-job-commit-by-job
Note that just like with pipelines, we don’t support using a constantly updated
The key difference here is the
tagVersionStrategy field, which indicates how we should sort a list of tags to choose the most recent software version.
increasing-tag: your tags are all integers, and we should choose the highest integer as the latest
semver-tag: your tags are a single semantic version (with or without a
v prefix), and we should choose the largest semantic version
branch-job-commit-by-job: your tags are of the format “branch-jenkinsJob.commitSha” (like
master-h5.5a52206), and we should choose the latest based on the highest jenkins job number (
h5 in this example)
semver-job-commit-by-job: your tags are of the format “semver-jenkinsJob.commitSha” (like
v1.12.1-h1159.b839a00), and we should choose the latest based on the highest jenkins job number (
h1159 in this example)
semver-job-commit-by-semver: your tags are of the format “semver-jenkinsJob.commitSha” (like
v1.12.1-h1159.b839a00), and we should choose the latest based on the largest semver (
v1.12.1 in this example)
If none of these work for you, you can provide your own regex to capture something to compare (using a capture group ). You must create a regex that parses valid tags and captures a string from them which can be compared either as an increasing number or a semantic version. The capture group must only capture one thing (you can’t have multiple capture groups).
For example, let’s say your tags look like
master-h5.5a52206 and we didn’t have a built in strategy for this style.
You’d define an artifact like this:
artifacts: - name: emburns/spin-titus-demo type: docker reference: my-docker-artifact # optional human-readable reference to be used elsewhere in the config, defaults to artifact name tagVersionStrategy: increasing-tag captureGroupRegex: ^master-h(\d+).*$
The regex capture group (the parens in the regex expression) indicates that out of the string tag we should grab any numbers after the
h and before the
The version strategy indicates that we will take the result of the capture group and compare it as an increasing number.
