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

Step 1: Create a .gitpod.yml file in Root

official Docs for configuring the .gitpod.yml: config-gitpod-file

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 )
