Using docker-lock --dockerfiles with find command

[andoks]

@michaelperel Is there a way to pass output from the find command to docker lock generate --dockerfiles? This seems to hold true for docker-compose files too

I have tried the following plus some other mutations of the same, but I can not find a way to do this that work. Does it perhaps require changes to how --dockerfiles argument is parsed in code?

mkdir test
cd test
echo "FROM ubuntu" > 1.dockerfile
echo "FROM ubuntu" > 2.dockerfile
docker lock generate --dockerfiles $(find . -type f -iname '*dockerfile')
cat docker-lock.json # shows only entry for 1.dockerfile
docker lock generate --dockerfiles $(find . -type f -iname '*dockerfile' -printf "%p ") # errors out with "file with no instructions"

Thank you for a great tool BTW! I hope I am not spamming too much with the issues (and this discussion), in that case please tell me =)

@andoks Apologies for the late reply, I did not have notifications turned on for discussions.

The syntax for passing a list in the CLI is as comma separated values, such as:

docker lock generate --dockerfiles=file1,file2

So in your case, you could say:

docker lock generate --dockerfiles "$(find . -type f -iname '*dockerfile' | paste -s -d ',' -)"

Hope this clears it up!

@michaelperel no problem, thank you for taking the time to answer 😄

Commenting for others following: As of #99, docker-lock supports more powerful globs, so you likely will not need to use find. Instead, if you want to recursively search for anything with the path *dockerfile, you could say:

docker lock generate --dockerfile-globs='**/*dockerfile'
