@ictus4u You are right, there are two .Mounts. The one inside HostConfig seems to reflect what you provided at the command-line (or docker compose, or ...) and is the one that we want to work with I think. For example, if you use secrets, they will also appear there (marked as read only). I have tried to fix with an extra "if" to see if that helps. @matheusyl can you check if the new version fixes your problems?

Hi.

I'm facing the exact same problem, and the last update dosen't seem to have fixed it; i see those errors and some run file are still empty

Thanks and best regards

For those who are restricted to public internet access can use cat instead of curl.

docker inspect --format "$(cat /path_to_file/run.tpl)" name_or_id_of_running_container

Please add

--user {{.Config.User}}

docker inspect --format "$(curl -s https://gist.githubusercontent.com/efrecon/8ce9c75d518b6eb863f667442d7bc679/raw/run.tpl)" ded0bdd038e4

Template parsing error: template: :22:15: executing "" at <.Mounts>: map has no entry for key "Mounts"

@uvlad7 --user now supported. @QGB try again, I have merged and adapted the changes from @ictus4u

docker inspect --format "$(curl -s https://gist.githubusercontent.com/efrecon/8ce9c75d518b6eb863f667442d7bc679/raw/run.tpl)" ded0bdd038e4

Template parsing error: template: :22:15: executing "" at <.Mounts>: map has no entry for key "Mounts"

Same error

Thank you for the great work! Unfortunately, I recognized that everything regarding health checks is missing:

  --health-cmd="redis-cli
  --raw incr ping"
  --health-interval=30s
  --health-timeout=10s
  --health-retries=3

Would it be possible to add them too?

This is fantastically simple and effective. Thank you so much!

thank you so much!

Starred! Simply amazing!

great work! so helpful
