Docker returns "json: cannot unmarshal string into Go value of type []string"

Question

I'm new to docker. I tried to launch an image with:

fig up -d --allow-insecure-ssl

But I get the following error message:

json: cannot unmarshal string into Go value of type []string

And I can't figure out how to fix it.

My fig.yml :

configrepo:
  image: docker-registry.backbasecloud.com/backbase/engage-configuration:latest
  environment:
    - SERVICE_NAME=configuration
  ports:
      - "8788:8080"

configserver:
  image: docker-registry.backbasecloud.com/backbase/engage-configserver:latest
  environment:
    SERVICE_NAME: configserver
  ports:
    - "8888:8888"
  links:
    - configrepo:configrepo
  dns: 172.17.42.1

docker version

fig --version

fig 1.0.1

Any ideas why I'm getting this error?

Answer 1

First, fig has long been migrated to docker compose .
Second, docker 1.6.2 is not the newest release of docker.

So before chasing that bug too much (in light of issues like 1638 ):

• update to docker compose and docker 1.8.2
• check your entrypoint in your docker-compose.yml : true should be /bin/true for instance.
