Using Docker/Fig with StrongLoop

I'm having a problem using Docker/Fig to set up StrongLoop.

'slc run' works locally but it runs into an error when I run 'fig up'

I have a very basic fig file:

web:
  build: .
  command: slc run
  volumes:
    - .:/srv/data
  ports:
    - "3000:3000"
  links:
    - mysql
mysql:
    image: mysql:latest
  ports:
    - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD:xxx

Edit: This is my Dockerfile

# Pull nodejs base image
FROM google/nodejs:0.10.30

RUN apt-get -y update

# Install stongloops
RUN npm install --global pg strongloop

#Get source code
RUN cd / && git clone https://github.com/dmathewwws/ios-api.git

# Install dependencies
RUN cd /ios-api && npm install

# Expose running port
EXPOSE 3000

WORKDIR /ios-api

This is the error returned:

Creating iosapi_mysql_1...

Solution

  • If you have copy/pasted your fig.yml accurately, it has an error in it.

    To use the dictionary format for the environment variables, you need a space between MYSQL_ROOT_PASSWORD: and xxx.

    mysql:
  image: mysql:latest
  ports:
    - "3306:3306"
  environment:
    MYSQL_ROOT_PASSWORD: xxx

    Alternatively you can use the array form, which is a list of strings of the form VAR=val:

    mysql:
  image: mysql:latest
  ports:
    - "3306:3306"
  environment:
    - MYSQL_ROOT_PASSWORD=xxx
