docker-compose volumes: no such file or directory-CodePudding

I have the following folder structure:

scripts/
--constraints.cypher
docker-compose.yml

This is my docker-compose.yml:

services:
  app-config-db:
    image: neo4j:latest
    container_name: app-config-db
    ports:
      - "7474:7474"
      - "7473:7473"
      - "7687:7687"
    volumes:
      - ./scripts:/var/lib/neo4j/scripts
    environment:
      - NEO4J_AUTH=neo4j/test123!
    command:
      - cypher-shell -u neo4j -p test123! --file /var/lib/neo4j/scripts/constraints.cypher

But when I run docker-compose up I get the following error:

error: exec: "cypher-shell -u neo4j -p test123! --file /var/lib/neo4j/scripts/constraints.cypher": stat cypher-shell -u neo4j -p test123! --file /var/lib/neo4j/scripts/constraints.cypher: no such file or directory

To me, it seems like the .scripts directory is not mounting correctly into my docker container, but everything seems in order. What am I doing wrong?

CodePudding user response：

The scripts directory gets mounted correctly. The problem here is that you are specifying the command in an array form so docker searches for the executable file "cypher-shell -u neo4j -p test123! --file /var/lib/neo4j/scripts/constraints.cypher" which is obviously not found. You can either specify the command as a string

services:
  app-config-db:
    image: neo4j:latest
    container_name: app-config-db
    ports:
      - "7474:7474"
      - "7473:7473"
      - "7687:7687"
    volumes:
      - ./scripts:/var/lib/neo4j/scripts
    environment:
      - NEO4J_AUTH=neo4j/test123!
    command: cypher-shell -u neo4j -p test123! --file /var/lib/neo4j/scripts/constraints.cypher

Or split all the options up:

services:
  app-config-db:
    image: neo4j:latest
    container_name: app-config-db
    ports:
      - "7474:7474"
      - "7473:7473"
      - "7687:7687"
    volumes:
      - ./scripts:/var/lib/neo4j/scripts
    environment:
      - NEO4J_AUTH=neo4j/test123!
    command:
      - cypher-shell
      - -u
      - neo4j
      - -p
      - test123!
      - --file
      - /var/lib/neo4j/scripts/constraints.cypher

This is similar to the CMD instruction in the Dockerfile. You can find more info in the compose file spec and the documentation for CMD.
