Setting Up My Environment

[AditModi]

I am looking to develop my application that fetches data from repo,
the Jenkins Pipeline should be able to perform the Docker-compose.yml commands.
the docker-compose.yml will contain the two images - node and mongo.
On successful completion of docker-compose it will build the repo.
for publishing the repo, I am not aware, how I can accomplish it.
I am working on my repo using the files provided in this repo.

I am getting a docker-compose command not found error.
I specified PATH and the error is gone.
I am getting a new error,
Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

Seems like it requires sudo access for running docker-compose,
Is there any workarounds for it.
Did manage to get a answer for it, been struggling on finding ways to override my docker image.
