Hi Everyone, I am trying to convert big old monolith bash script to ansible, and I’m about 90% of the way there. I am having a bit of trouble with one element, the docker entrypoint. The original code along with my Ansible attempt and the entrypoint debug output is here: [https://pastebin.com/J1j49aKT](https://pastebin.com/J1j49aKT) I _think_ I have done everything correctly, but I do not get a populated license file I’m sure there is something glaringly obvious, but I can’t seem to put my finger on it. Thanks, Dave ---

Ansible won't do such magic for you. The `entrypoint` option expects a list of strings; if it is not a list but a single string, it is treated as a comma-separated concatenated list, i.e. split by commas. In your case, you end up with a single string containing the whole command line. This is passed to docker as the executable to run in your container, which will obviously fail. You have to compose a proper `entrypoint` list. Also, the redirect is not part of the thing docker should execut, but something you have to handle on ansible level (i.e. ask the docker\_container module to capture stdout for you). Cheers, Felix ---

Whoops, upon further scrutiny, I have realised I should be using entrypoint, but command instead.

Hello, Sorry if it’s not the right place, I’m thinking my problem is little bit similar. In guacamole install process, It’s suggest to do: **docker** run --rm guacamole/guacamole /opt/guacamole/bin/initdb.sh --mysql \> _initdb.sql_ I want to convert in proper way with ansible. This is my task: - name: Extract SQL Guacamole community.general.docker\_container: name: guacamole-sql-extract image: “guacamole/guacamole:latest” container\_default\_behavior: no\_defaults command: “/opt/guacamole/bin/initdb.sh --mysql \> /srv/live/{{ app\_name }}/initdb.sql” But not file SQL is output. I tried with **container\_default\_behavior: compatibility, entrypoint** instead of **command** but no more work. When I tried docker run […] dry, it’s work. Thanks ---

You need to remove the "\> /srv/...", and pass the `detach: false` option to docker\_container to enable non-detaching and stdout capturing. Then you need to register the output of the task, and extract the output from there as `result.container.Output`. Also, your command line specifies `--rm`, which is equivalent to `auto_remove: true`.

Hello, Thanks, but without argument, docker ansible failed. - name: Extract SQL Guacamole community.general.docker\_container: name: guacamole-sql-extract image: “guacamole/guacamole:latest” container\_default\_behavior: no\_defaults detach: false # command: “/opt/guacamole/bin/initdb.sh --mysql \> initdb.sql” register: sqlextract And when I let command and detach false, same error : “msg”: “Wrong number of arguments.\nUSAGE: /opt/guacamole/bin/initdb.sh [–postgres | --mysql]\nWrong number of arguments.\nUSAGE: /opt/guacamole/bin/initdb.sh [–postgres | --mysql]\nWrong number of arguments.\nUSAGE: /opt/guacamole/bin/initdb.sh [–postgres | --mysql]\nWrong number of arguments.\nUSAGE: /opt/guacamole/bin/initdb.sh [–postgres | --mysql]\nWrong number of arguments.\nUSAGE: /opt/guacamole/bin/initdb.sh [–postgres | --mysql]\nWrong number of arguments.\nUSAGE: /opt/guacamole/bin/initdb.sh [–postgres | --mysql]\n”, “status”: 1 I have to set command to get work. May I used volume, but how? Because with dry run docker run, it extract in the folder in argument. I don’t know… Sorry.
