Hi,
I'm running into an issue with how the Ansible Docker module handles JSON
data passed in as an environment variable. I'm currently running Ansible
2.0.2.0. My docker env variable is defined like this:
dockerhub_auth: {"https://index.docker.io/v1/": {"auth": "foo", "email":
"bar" }}
The above var is then referenced like this
- name: Start ecs-agent container
docker:
name: ecs-agent
image: amazon/amazon-ecs-agent:v{{ ecs_agent_version }}
state: reloaded # asserts containers are running and restarts any
that have any images or configs out of date.
pull: always # the registry will be checked for a newer version
of the image' each time the task executes
detach: true
restart_policy: on-failure
restart_policy_retry: 10
net: bridge
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- /var/log/ecs/:/log # Z mount option for SELinux available in
Ansible 2.1
- /var/lib/ecs/data:/data
- /sys/fs/cgroup:/sys/fs/cgroup:ro
- /var/run/docker/execdriver/native:/var/lib/docker/execdriver/
native:ro
ports:
- 127.0.0.1:51678:51678
expose:
- 51678
env:
ECS_LOGFILE: /log/ecs-agent.log
ECS_LOGLEVEL: info
ECS_DATADIR: /data
ECS_CLUSTER: "{{ ecs_cluster }}"
ECS_ENGINE_AUTH_TYPE: dockercfg
ECS_ENGINE_AUTH_DATA: "{{ dockerhub_auth | to_json }}"
When I do a debug on "{{ dockerhub_auth | to_json }|" the data shows as
properly formatted json. However, when I run the above task, the variable
seems to be passed in with single quotes. See below:
[root@localhost ~]# docker inspect 3ae5048a8b03|grep ECS_ENGINE_AUTH_DATA
"ECS_ENGINE_AUTH_DATA={'url': {'email': 'bar', 'auth':
'foo'}}",
Am I encountering a limitation in the Docker module or is there another way
I can pass JSON data through to the container? I saw that the env_file
flag for Docker is coming in Ansible 2.1, so that's a possible solution,
but I encountered other Docker errors when trying to use the ansible 2.1
devel branch.
Thanks in advance for the help!
