It's free!
Support / SLA

N/A

Not specifically mentioned, probably not.

Yes

Paid support available: https://rancher.com/pricing/
Paralellism
Every CI servers tends to address this differently (parallel, distributed, build matrix). Some of it is just marketing, and some is just nuance. For this table, parallel means that tasks can be run concurrently on the same machine, distributed means that tasks can be scaled horizontally, on multiple machines
How to split tests in parallel in optimal way with Knapsack Pro

Yes

Automated parallalelization for code analysis, as well as support for running tasks in parallel

Yes

You can run multiple parallel steps within a build stage
Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines

Containers support / Build environment

Yes

Tests run in isolated containers. Docker support available.

Yes

Analytics / Status overview
Analytics and overview referrs to the ability to, at a glance, see what's breaking (be it a certain task, or the build for a specific project)

Yes

Besides classic CI overview, they also provide static code analysis insights, which is a differentiator for Scrutinizer

Yes

Not particularly clear, but it appears you can monitor stats in a Grafana dashboard: https://rancher.com/docs/rancher/v2.x/en/project-admin/tools/monitoring/
Management support
How easy is it to manage users / projects / assign roles and permissions and so on

Yes

Additional seats available for every plan at $14.90 per seat, per month.

Yes

User management is available, with specific roles assigned, or permissions to certain resources and projects
Self-hosted option

No

Yes

Hosted plans / SaaS

Yes

No

Build pipelines
A continuous delivery pipeline is a description of the process that the software goes through from a new code commit, through testing and other statical analysis steps all the way to the end-users of the product.

Yes

Pipelines as code (YML files)

Yes

Pipelines as code (YML files), but also manageable via the UI
Reports
Reports are about the abilty to see specific reports (like code coverage or custom ones), but not necesarily tied in into a larger dashboard.

Yes

Yes

Ecosystem
Besides the official documentation and software, is there a large community using this product? Are there any community-driven tools / plugins that you can use?

No

N/A

Specific language support: Ruby
Some CI servers have built-in support for parsing RSpec or Istanbul output for example and we mention those. Some others make it even easier by detecting Gemfiles or package.json and automate parts of the process for the developer.

Yes

Code analysis (automated code reviews) are available for Ruby, as well as specific documentation for setting up a Ruby project: https://scrutinizer-ci.com/docs/guides/ruby. Frameworks like Ruby on Rails are supported. They also provide tools like bundler-audit, for identifying vulnerable gems: https://scrutinizer-ci.com/docs/tools/ruby/bundler-audit/

N/A

Pipelines / CI is just a small part of Rancher. No specific support mentioned.
Specific language support: JavaScript

Yes

Automated code reviews are available for Javascript as well as specific documentation for setting up a Node.js project: https://scrutinizer-ci.com/docs/guides/javascript. Typescript is also supported.

N/A

Pipelines / CI is just a small part of Rancher. No specific support mentioned.
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

Light integration with third party systems, mainly code management frameworks like GitHub, Bitbucket, GitLab.

Yes

Integrations available for GitLab, GitHub and Bitbucket
API
Custom integreation is available, via an API or otherwise, it's mentioned separately as it allows further customization than any of the Ecosystem/Integration options

Yes

Comprehensive REST API available: https://scrutinizer-ci.com/docs/api/

Yes

REST API available. It provides introspection and documentation: https://github.com/rancher/api-spec/blob/master/specification.md#filtering. It should offer enough access to allow building whatever customizations or integrations with 3rd party tools deemed necessary.
Auditing

N/A

Unclear from the documentation, but most likely available.

Yes

Allows logging to various systems (Kafka, Elastic, etc) which should make audit possible
Additional notes

The code analysis features seem great, the offer for similar tools is quite light. Seems similar to lgtm.com

Rancher is a full software stack for container orchestration, going as far as building their own Linux distribution (RancherOS). Using Rancher seems more like a decision to be made considering all other features Rancher offers, not just the CI server. Also worth noting that Rancher uses Jenkins under the hood, but the engine is locked so projects can't just be migrated between the two.

How to run parallel tests on Scrutinizer CI and Rancher Pipelines
to execute 1-hour test suite in 2 minutes?

How it works

1. Install Knapsack Pro client in your project


2. Add Knapsack Pro client to your current CI server and run your tests in parallel



3. Update your CI server config file to run tests in parallel with Knapsack Pro

Knapsack Pro in Queue Mode will split tests in a dynamic way across parallel CI nodes to ensure each CI node finish work at a similar time. Thanks to that your CI build time is as fast as possible. It works with many supported CI servers.

Features that make your tests perform better

  • Queue mode see video

    Dynamic tests allocation across Scrutinizer CI and Rancher Pipelines parallel jobs. Autobalance tests to get optimal test suite split betweeen CI nodes.

  • Regular mode see video

    Test suite split based on time execution. Generates subset of test suite per CI node before running tests.

  • Fallback mode

    Network issues? Not a problem, run tests anyway! Auto switch to the fallback mode to not depend on Knapsack Pro API.

  • All supported test runners

    Ruby: RSpec, Minitest, Test::Unit, Cucumber, Spinach, Turnip.

    JavaScript: Cypress.io, Jest

We've been really enjoying Knapsack Pro, it's been saving us a ton of time.

Devin Brown Software Engineer at Pivotal

This is a fantastic product, it's been a total game-changer for us.

Geoff Harcourt CTO at CommonLit

We are using CircleCI and we noticed that builds were being limited by the slowest parallelized container. Knapsack Pro was really east to setup and we saw huge improvements right away. Thank you for making this tool!

Martin Sieniawski Software Engineer at Collage

Knapsack Pro has helped us build an insanely fast and scaleable build pipeline with almost no setup or maintenance.

Tim Lucas Co-founder of buildkite.com

Knapsack Pro saves us hours of engineer waiting time every week, and is the best solution for keeping our tests load balanced that we've used to date.

Michael Amygdalidis Senior Software Engineer at Popular Pays

I just logged into my account expecting it to say that I needed to add a credit card and was so surprised and delighted to see the trial doesn't count usage by calendar days but by testing days! This is incredible! I love it!!!

I just wanted to say that I really appreciate that small but very huge feature. Thank you for being so thoughtful :)
