But next I got error :

$ docker-compose up -d --build
ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?

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

I searched for a decision and found next decision as, but got error :

$ export DOCKER_HOST=127.0.0.0/8
#:/mnt/_work_sdb8/wwwroot/lar/DockerApps/votes_docker$ docker-compose up -d --build

docker.errors.DockerException: Bind address needs a port: 127.0.0.0/8

I used port 127.0.0.0/8 as it was mentioned in output of docker info

command. But looks like that not valid option?

I suppose that docker-compose up -d --build command must be run under non root user. Is it so ?

What is the right way ?

Thanks!
