Anyone got a good example of taking `.

[willow schooner]

haven't seen anything around 🙏 . Should be straightforward to implement.

[hoary cargo]

@willow schooner I can use PHP to grab the .env and split on "\n" and loop over it

[stoic epoch]

Yeah we just did this @woven prism do you have the code sample handy somewhere. (from the legend work)

[hoary cargo]

😄 thanks! looking fwd to seeing it

[woven prism]

@hoary cargo how about this?
https://daggerverse.dev/mod/github.com/quartz-technology/daggerverse/magicenv@627fc4df7de8ce3bd8710fa08ea2db6cf16712b3

[hoary cargo]

@woven prism looks decent, I'll try it out.

btw .. maybe you can add a 2nd user argument for pattern so if the key starts with a pattern, then include it

magicenv('.env', 'DB_')

As if I call this on the MySQL container, then I only want the DB_* ones .. whereas the webapp, I want them all. It's a good way to avoid conflicts IMO

[woven prism]

Sounds like a good PR or issue 🙂 Module was made by @pliant drift

[pliant drift]

Ohh yeah! I need to update it because I made it loog time ago

[stoic epoch]

@woven prism wasn't there some other thing we did using current_module - or am I completely hallucinating?

[woven prism]

We did. But not necessary, I think.

I’m currently using this command to good effect to fill in templates with $FOO

https://github.com/jpadams/legend-daggerize-minimal-maven/blob/main/dagger/src/index.ts#L168
Install package with envsubst in it.

Use it:

@stoic epoch let's move the chat to here 🙂

@woven prism

I wanna grab the contents of a file, from a Directory and store it in a variable.. specifically the .env file

is there a way on the Directory class to grab the contents of a file? or so I have to do

function(Directory $dir) {
  $this->container()->withExec(['cat', '.env'])->stdout();
}

Where do I use $dir ?

probably withMountedDirectory() first?

[stoic epoch]

I believe you must do stdout()

Yes and then you woul dalso need to say WithWorkDir($dir)

[woven prism]

contents(), right?

Oh I see , withExec in there

[stoic epoch]

contents would tell you the files -- but I assume you want the value of a file, right Paul?

[woven prism]

entries() is like ls

contents() returns a string

[stoic epoch]

Oh -- sorry I am confused!

[woven prism]

Afkb for a quick walk, will weigh in in a little bit

[hoary cargo]

build() = dockerBuld() btw ..

and then once I've got a container that's been built from a Dockerfile .. then I wanna load the .env vars into that container

(after I'm gonna do WithService('db') )

Is there a better way to get a file's contents, instead of 'cat' ?

[stoic epoch]

Yes it should be something like

->file(".env)->contents()

[hoary cargo]

testing

is this on Directory $source?

or is this on Container?

[stoic epoch]

Its on directory

[hoary cargo]

$envContents = $source->file('.env')->contents();

testing

WORKED ❤️‍🔥

[stoic epoch]

nice!

[hoary cargo]

@stoic epoch @woven prism here is the sexyness

PHP has builtin parse_ini_string ... which is what the .env file format is .. so i used file()->contents() and took it from there

I just added that $prefix arg .. .so I can say I want all the DB_ keys or all the REDIS_ keys or whatnot ..

Now .. this is how I load all env vars

        $container = $this->loadContainerEnvVars($container, $source);

and this is how I only load the DB args

        $container = $this->loadContainerEnvVars($container, $source, 'DB_');

but inside the code I can break out and call $this-getEnvVars($source, 'DB_') if I just want them as an array, rather than it auto-adding them to the running $container

🙂

[hoary cargo]

Now we're cookin'

gnight

[dull ravine]

I am not a php dev so forgive me if I'm off base. Does php support higher order functions? You could use With to maybe clean this up even further. Here's Go ref - https://pkg.go.dev/dagger.io/dagger#Container.With

Here's a very simple example

func loadEnvVars(d *Directory) WithContainerFunc {
  return func(r *Container) *Container {
    // Process env vars and add to container. Return it.
  }
}

Then when you set up the container

myContainer.With(loadEnvVars(myDir))

[hoary cargo]

Hey @dull ravine - no you can't modify the Container class, as that's owned by the Dagger SDK, and not the userland caller.

We actually do this a lot in PHP, by adding a with() method to things, so it'll modify and return a new instance.

Ways to achieve this are to sub-class it, and make your own child Container class, to add a 'with' method ... and then it'll work like Golang

[hollow frigate]

He's talking about a feature that every SDK should have, including PHP. See SDK Contribution Guide > Helpers. This used to be documented in a guide. All of our SDKs work the same way here:

• Go
• Python
• TypeScript
  This is done in codegen, by detecting if an object type has any fields that return the same object type, in which case the method is added to the resulting client binding of the object (example in Python). See original issue for this feature: https://github.com/dagger/dagger/issues/3885.
