What is MetaCall?
MetaCall helps you build serverless applications using a more fine-grained, scalable and NoOps oriented Function Mesh instead of ServiceMesh and DevOps approach. It automagically converts your code into a Function Mesh and auto-scales individual hot parts or functions of your app.
Need of an Automated Cloud Dev Environment
As MetaCall being an Open Source Software, the major block to start contributing to the Project is to Setup the Project Locally with all custom configurations, tools, libraries that a particular project requires. And I've been with MetaCall for a year, and the majority of the queries we get on our internal discord server are about setup and dealing with various issues. That's how I started, too. So with this Automated Cloud Dev Environment on Gitpod, you can just code, build, test, and ship without having to worry about setting up all the environments!
In this blog, i will be automating the setup of metacall/core
on Gitpod.
I will be automating this Installation official docs of MetaCall

For This Project, requirement was to build the project, pulling metacall docker images & executing them.
tasks:
- name: Build Metacall
init: |
mkdir build && cd ./build
cmake ..
cd ..
command:
sudo env PATH=$PATH cmake --build . --target install
- name: Pulling metacall Docker Images
init: |
docker pull metacall/core
docker pull metacall/core:dev
mkdir -p $HOME/metacall
command:
docker run -e LOADER_SCRIPT_PATH=/metacall -v $HOME/metacall:/metacall -w /metacall -it metacall/core:dev /bin/bash
- name: Pulling metacall-cli Docker Image
init: |
docker pull metacall/core:cli
command:
docker run -e LOADER_SCRIPT_PATH=/metacall -v $HOME/metacall:/metacall -w /metacall -it metacall/core:cli
Tasks Description
- Task 1: It will Build all the files
- Task 2: It will pull & execute
metacall/core:dev
docker image
- Task 3: It will pull & execute
metacall-cli
docker image
At the time of workspace preparation, this .gitpod.yml
file will setup all of the essential environments. and Your Project Will be ready to code under _ 60 seconds_ (Gitpod β‘)

Repository of Gitpod
, an Automated Open Source Cloud Dev. Environment. Use it or just give it a π for their amazing work.
gitpod-io / gitpod
The developer platform for on-demand cloud development environments to create software faster and more securely.
Gitpodβs developer platform provides on-demand, pre-configured environments that automatically integrate into any tool, library, or dependency required for creating software. Gitpod workspaces are the fastest and most secure way to ship software and are as easy as adding a .gitpod.yml file to the root of any repository.

Features
-
Dev environments as code - Gitpod is like infrastructure-as-code, but for your development environment. Gitpod defines your editor extensions and requires dependencies in a declarative
.gitpod.yml
configuration. Spinning up dev environments is easily repeatable and reproducible empowering you to automate, version-control, and share dev environments across your team. - Prebuilt dev environments - Gitpod continuously prebuilds all your git branches similar to a CI server. Control how Gitpod pre-configures and initializes environments before you even start a workspace through tasks commands in your .gitpod.yml. No more watching apt-get or npm install again.Β
