Docker-compose: cannot build WITHOUT sudo but I can run containers without it
The cause of the problem is that you have a volume mount point with root:root
owner & group and caused this behavior.
The solution to this problem is to create a file named .dockerignore
and put all the folders mounted as volumes.
For example if you have the following docker-compose.yml
version: '2'
services:
data_map_prod:
build:
context: .
dockerfile: Dockerfile
image: 'pcmagas/data-map:latest'
links:
- 'neo4j'
- 'mongodb'
volumes:
- './docker-volumes/app_dev:/var/log/datamap'
ports:
- "9780:9780"
environment:
NEO4J_HOST: 'neo4j'
MONGO_CONNECTION_STRING: 'mongodb://mongodb:map'
data_map_dev:
build:
context: .
dockerfile: Dockerfile_dev
image: 'pcmagas/data-map:dev'
links:
- 'neo4j_dev'
- 'mongodb'
volumes:
- './src:/opt/map/src'
- './www:/opt/map/www'
- './package.json:/opt/map/package.json'
- './docker-volumes/app_dev:/var/log/datamap'
ports:
- "9781:9780"
environment:
NEO4J_HOST: 'neo4j_dev'
NEO4J_USER: 'neo4j'
NEO4J_PASSWORD: 'neo4j'
MONGO_CONNECTION_STRING: 'mongodb://mongodb:map_dev'
neo4j_dev:
image: 'neo4j'
ports:
- '7474:7474'
volumes:
- './docker-volumes/neo4j_dev/data:/data'
environment:
NEO4J_AUTH: 'neo4j/neo45j'
neo4j:
image: 'neo4j'
volumes:
- './docker-volumes/neo4j/data:/data'
environment:
NEO4J_AUTH: 'neo4j/neo45j'
mongodb:
image: 'mongo'
ports:
- '27017:27017'
volumes:
- './docker-volumes/mongodb/:/data/db'
Then you should create the following .dockerignore
:
./docker-volumes
As you can see all the volumes are in ./docker-volumes
folder.

One of the reason is that any file used to build the docker image is not owned by the current user. We can change this by using this command:
sudo chown -R $USER .
