Not sure where to start?

Follow these steps and you’ll be right at home.

  1. See the Community Welcome Guide for how, where, and why to contribute.

  2. Sign up for a MeshMate to find the perfect Mentor to help you explore the Layer5 projects and find your place in the community:

  • Familiarize yourself with all the Layer5 projects (Take a look at the Community Drive and the Layer5 Repository Overview: Spend time understanding each of the Layer5 initiatives through high-level overviews available in the community drive and through discussions with your MeshMate.
  • Identify your area of interest: Use the time with your MeshMate to familiarize yourself with the architecture and technologies used in the projects. Inform your MeshMate of your current skills and what skills you aim to develop.
  • Run Meshery: Put on your user hat and walk-through all of Meshery’s features and functions as a user.
  • Build Meshery: Confirm that you have a usable development environment.
  • Communicate with the Layer5 community by joining the Slack account.
  • Contribute by grabbing any open issue with the help-wanted label and jump in. If needed, create a new issue. All pull requests should reference an open issue. Include keywords in your pull request descriptions, as well as commit messages, to automatically close issues in GitHub.

General Contribution Flow

To contribute to Meshery, please follow the fork-and-pull request workflow described here.

Signing-off on Commits (Developer Certificate of Origin)

To contribute to this project, you must agree to the Developer Certificate of Origin (DCO) for each commit you make. The DCO is a simple statement that you, as a contributor, have the legal right to make the contribution.

See the DCO file for the full text of what you must agree to and how it works here. To signify that you agree to the DCO for contributions, you simply add a line to each of your git commit messages:

Signed-off-by: Jane Smith <jane.smith@example.com>

In most cases, you can add this signoff to your commit automatically with the -s or --signoff flag to git commit. You must use your real name and a reachable email address (sorry, no pseudonyms or anonymous contributions). An example of signing off on a commit:

$ commit -s -m “my commit message w/signoff”

To ensure all your commits are signed, you may choose to add this alias to your global .gitconfig:

~/.gitconfig

[alias]
  amend = commit -s --amend
  cm = commit -s -m
  commit = commit -s

Or you may configure your IDE, for example, Visual Studio Code to automatically sign-off commits for you:

Meshery Contribution Flow

Meshery is written in Go (Golang) and leverages Go Modules. UI is built on React and Next.js. To make building and packaging easier a Makefile is included in the main repository folder.

Relevant coding style guidelines are the Go Code Review Comments and the Formatting and style section of Peter Bourgon’s Go: Best Practices for Production Environments.

Please note: All make commands should be run in a terminal from within the Meshery’s main folder.

Prerequisites for building Meshery in your development environment:

  1. Go version 1.11+ installed if you want to build and/or make changes to the existing code.
  2. GOPATH environment variable should be configured appropriately
  3. npm and node should be installed on your machine, preferably the latest versions.
  4. Fork this repository (git clone https://github.com/layer5io/meshery.git), clone your forked version of Meshery to your local, preferably outside GOPATH. If you happen to checkout Meshery inside your GOPATH and you have a version of Go prior to version 1.13, please set an environment variable GO111MODULE=on to enable GO Modules.

Build and run Meshery server

To build & run the Meshery server code, run the following command:

make run-local

Any time changes are made to the GO code, you will have to stop the server and run the above command again. Once the Meshery server is up and running, you should be able to access Meshery on your localhost on port 9081 at http://localhost:9081. One thing to note, you might NOT see the Meshery UI until the UI code is built as well. After running Meshery server, you will need to select your Cloud Provider by navigating to localhost:9081. Only then you will be able to use the Meshery UI on port 3000.

Building Docker image

To build a Docker image of Meshery, please ensure you have Docker installed to be able to build the image. Now, run the following command to build the Docker image:

make docker
