Containerized Build Runner

Introduction

A docker image based from python:2.7.11 that can be used to run a lcp-compose commands in a containerized environment.
Dockerfile for the image can be found in the lcp-compose repository at dockerfiles/build-image/Dockerfile.

Purpose

Since lcp-compose makes certain assumptions regarding the environment that it is being executed on, containerizing the runner guarantees a consistent environment.

Assumptions

• The docker socket mounted from the host at /var/run/docker.sock
• If any docker volumes are mounted or containers are built during a test run, the directories and /path/to/Dockerfile's should be mounted from the host's file-system at exact absolute paths.

Environment Variables

• UID: Linux user id of the test user.
• GID: Linux group id of the test user.
• PROJECT_NAME: Namespace for the docker-compose project.
• PROJECT_DIR: Directory which the test commands are executed.

How to use the build image

PROJECT_NAME=points_service
PROJECT_DIR=$(pwd) # /path/to/points_service
docker run --rm --network=host \
    --env UID=$(id --user) \
    --env GID=$(id --group) \
    --env PROJECT_NAME=$PROJECT_NAME \
    --env PROJECT_DIR=$PROJECT_DIR \
    --volume "/var/run/docker.sock:/var/run/docker.sock" \
    --volume "$PROJECT_DIR:$PROJECT_DIR" \
