sudo - How to run docker-compose up without root privilages?

I want to run docker-compose up as non-root user.
When I execute:

sudo docker-compose up

it works great, but when I execute:

docker-compose up

an error is shown:

 TITLE>Network Error













Network Error (tcp_error)





A communication error occurred: ""

I have added user to docker group and docker commands work without sudo, however docker-compose is causing trouble.

I've found solution. The invalid proxy was set for non-root user.
I've edited /etc/profile and now it works ok.
