Hi! I think i have an improvement for when no docker containers are running.

Adding this if before the for entry in output: tells the user if no docker containers are running

#etc...

if len(output) == 0:
    print("No running docker containers 😔")
else:
    print("")

for entry in output:
#etc...

Before

After

Good idea. Thanks for your contribution @KrappRamiro :)
I updated the gist.

@MaaxGr Thank YOU! I really love this script, its beautiful!

Awesome script!

I've made the following changes to show at a glanced if each container is running or not:

# line 20, added `-a` to the docker ps command
# (optional: also added my local timezone for convinance since my server is in UTC)
+ command = "TZ='Europe/Paris' docker ps -a --format '{\"ID\":\"{{ .ID }}\", \"Image\": \"{{ .Image }}\", \"Names\":\"{{ .Names }}\", \"Status\":\"{{ .Status }}\", \"CreatedAt\":\"{{ .CreatedAt }}\", \"Ports\":\"{{ .Ports }}\"}'"

# line 36, added a way to crudely set color if `Up` or `Exited` is present in the string
+ status = entry_json_object["Status"].replace("Up", f"{bcolors.OKGREEN}Up{bcolors.OKDARKGRAY}").replace("Exited", f"{bcolors.FAIL}Exited{bcolors.OKDARKGRAY}")

result:
