  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 <>

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:


  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:

Documentation Contribution Flow

Please contribute! Meshery documentation uses GitHub Pages to host the docs site. Learn more about Meshery’s documentation framework. The process of contributing follows this flow:

  1. Create a fork, if you have not already, by following the steps described here
  2. In the local copy of your fork, navigate to the docs folder. cd docs
  3. Create and checkout a new branch to make changes within git checkout -b <my-changes>
  4. Edit/add documentation. vi <specific page>.md
  5. Run site locally to preview changes. make site
  6. Commit, sign-off, and push changes to your remote branch. git push origin <my-changes>
  7. Open a pull request (in your web browser) against our main repo:

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, 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

Writing a Meshery Adapter

Meshery uses adapters to provision and interact with different service meshes. Follow these instructions to create a new adapter or modify and existing adapter.

  1. Get the proto buf spec file from Meshery repo: wget
  2. Generate code
    1. Using Go as an example, do the following:
      • adding GOPATH to PATH: export PATH=$PATH:$GOPATH/bin
      • install grpc: go get -u
      • install protoc plugin for go: go get -u
      • Generate Go code: protoc -I meshes/ meshes/meshops.proto --go_out=plugins=grpc:./meshes/
    2. For other languages, please refer to for language-specific guides.
  3. Implement the service methods and expose the gRPC server on a port of your choice (e.g. 10000).

Tip: The Meshery Adapter for Istio is a good reference adapter to use as an example of a Meshery Adapter written in Go.

mesheryctl Contribution Flow

mesheryctl is written in Golang or the Go Programming Language. For development use Go version 1.15+.

The /mesheryctl folder contains the complete code for mesheryctl.

After making changes, run make in the mesheryctl folder to build the binary. You can then use the binary by, say, ./mesheryctl system start.

mesheryctl command reference

Detailed documentation of the mesheryctl commands is available in the Meshery Docs.

Guidelines and resources for contributing to mesheryctl

mesheryctl might be the interface that the users first have with Meshery. As such, mesheryctl needs to provide a great UX.

The following principles should be taken in mind while designing mesheryctl commands-

  1. Provide user experiences that are familiar.
  2. Make the commands and their behavior intuitive.
  3. Avoid long commands with chained series of flags.
  4. Design with automated testing in mind, e.g. provide possibility to specify output format as json (-o json) for easy inspection of command response.

Part of delivering a great user experience is providing intuitive interfaces. In the case of mesheryctl, we should take inspiration from and deliver similar user experiences as popular CLIs do in this ecosystem, like kubectl and docker. Here is relevant kubectl information to reference - Kubectl SIG CLI Community Meeting Minutes, contributing to kubectl, code.

mesheryctl uses the Cobra framework. A good first-step towards contributing to mesheryctl would be to familiarise yourself with the Cobra concepts.

For manipulating config files, mesheryctl uses Viper.

A central struct is maintained in the mesheryctl/internal/cli/root/config/config.go file. These are updated and should be used for getting the Meshery configuration.

For logs, mesheryctl uses Logrus. Going through the docs and understanding the different log-levels will help a lot.

mesheryctl uses golangci-lint. Refer it for lint checks.

UI 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.

Install UI dependencies

To install/update the UI dependencies:

make setup-ui-libs

Build and export UI

To build and export the UI code:

make build-ui

Now that the UI code is built, Meshery UI will be available at http://localhost:9081. Any time changes are made to the UI code, the above code will have to run to rebuild the UI.

UI Development Server

If you want to work on the UI, it will be a good idea to use the included UI development server. You can run the UI development server by running the following command:

make run-ui-dev

Make sure to have Meshery server configured, up and running on the default port http://localhost:9081 before proceeding to access and work on the UI server at http://localhost:3000. Any UI changes made now will automatically be recompiled and served in the browser.

Running Meshery from IDE
