#How to copy file to an environment with container-use?

I'm trying to setup container-use with my legacy Rails project. In Rails there was a convention to store secrets in config/secrets.yml, which is not committed to repository, so it's not copied to environment by default. How to copy a file to environment manually?
I tried to use file reference with secrets https://container-use.com/secrets#secret-types and then do
container-use config install-command add "echo $SECRETS > ./config/secrets.yml" but now the formatting is screwed up, and the file is not valid yml.

Is there some way to do this with container-use or maybe there's an escape hatch which I can use, to use dagger for the environment directly?

How to copy file to an environment with container-use?

@jolly snow i'd use an install command to write a secrets.yml that looks like this

production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

and then set up a cu secret like container-use config secret set SECRET_KEY_BASE "your value here, either from an env var set on the host machine, from a pw manager, etc"

#

you could also maybe do it as a whole file, using a very similar technique as what you've already got, file://path is a supported secret protocol

#

which would be like echo $SECRETS_YML > ./config/secrets.yml as an install command, and setting the env secret like container-use config secret set SECRETS_YML file://config/secrets.yml

Yeah, that's what I'm supposed to do, I understand. But as I said it's a legacy project, and this file kind of got out of hand, and just contains a lot of configuration, that is not accessible through env variables alone. I can refactor it for sure, but that would be more work.

I was hoping there would be an easier way to just do "hey, copy this file from host here"

yeah the file protocol will let you do that (and conveniently it'll also actually try to hide the contents of the file from logs and whatnot)

container-use config secret set SECRETS_YML file://config/secrets.yml when I did that it removed all of the indentation from contents, so it's not working straight away

#

I don't know if it's even possible to restore the indentation correctly after echo

oh oh oh i know this one

#

echo "$SECRETS" > ./config/secrets.yml

#

the quotes

#

it's like they say, there are 3 hard problems in computer science: counting and posix shell quoting

#

(either that or we have a classic llm-written bug where something is unnecessarily stripping whitespace, but im like 70% sure it's the quotes lol)

jolly snow
#

You're right! It was those damn quotes

#

It works now, thank you

#

Should've figure this out myself. Long day..
