@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

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

great work! so helpful

Thanks for this!

To create files with the run commands for all of your running containers:
docker ps -q | xargs -I % sh -c 'docker inspect --format "$(curl -s https://gist.githubusercontent.com/efrecon/8ce9c75d518b6eb863f667442d7bc679/raw/run.tpl)" % > %'

Thanks for this!

Good job. Slightly modify it to use the container name as the file name.

docker ps -q | xargs -I % sh -c 'docker inspect --format "$(curl -s https://gist.githubusercontent.com/efrecon/8ce9c75d518b6eb863f667442d7bc679/raw/run.tpl)" % > $(docker inspect --format "{{.Name}}" % | cut -c2-)'

what a great concept! almost perfect in my use -- had to manually gather to re-assign MAC address (since used to assign IP in DHCP env)

--mac-address=aa:bb:...

Hi @efrecon

I would like to thank you for this template.

I would like to contribute by modifying the iteration through the ports to iterate through every element rather than choosing only the first.

The change is available in my fork: https://gist.github.com/snikhil1998/9176b8583475693f1f8d1f1f5c6e76e4

Motivation: I noticed the incomplete list of port bindings when recreating docker containers with this template, so I modified it to fix the issue.
