Problem using default(omit) in docker environment variable

[Chad McElligott]

I am trying to use the `| default(omit)` filter in the environment variable declaration of my docker role, for example:

- name: start container

  docker:

    name: foo

    image: foo

    state: reloaded

    pull: always

    restart_policy: always

    env:

      COMMAND: '{{ command|default(omit) }}'

    net: default

Then I'm using the role in the playbook without specifying the command variable, which I would expect would omit any value from being set to the environment variable. Instead, this is what is in the environment when the container is started:

COMMAND=__omit_place_holder__4aee0541e67c9db52882aecb3a955196572ae0f8

any ideas what I could be doing wrong?

omit won't work for subkeys. You can omit env, but not entries inside it.

Thanks Brian. Sorry for redundant post, I found a previous group post mentioning this.
