How to source an env file created by another task

[waterworthd-cim]

I have a task (create-env) which generates various .env files, including a codeartifact env file which contains a token that expires every 12 hours.

Issue is dotenv: ['.codeartifact.env'] seems to run before any task, so it uses the previous (maybe expired) token.

I've tried explicitly sources the file via set -a; source .env; set +a but this only sets the ENV variables locally.

In general I need to export vars in one command (create-env, run by build) and import them for all subsequent tasks. Is this possible (or is there some other pattern)? I really want to do this so tasks from imported taskfiles also inherit the environment

You need a bootstrap strategy. I would suggest a task (dep) which takes a checksum of the .codeartifact.env file, then generates it, and then takes a second checksum. If the checksum changed .... call task again with the same parameters ... that will reload the .env file and you will be good to go. Otherwise, if the checsum did not change, just continue.

It will take some effort to figureout, but it should be possible.

So for my understanding why is the .env file reloaded in this case (if I understand correctly - when the same task is called with the same parameters). How does this differ from one task calling another - if the .env file not reloaded other than when a task is called recursively?

In this case task codeartifact:login only invokes the aws codeartifact login cmd if the file doesn't not exist or was created > n hours ago. If the file exists and was created recently (I do this is the task status key) the cmd will not be executed. So in order to do the check sum I'd have to create another "wrapper" task right? This task would look something like

tasks:
   codeartifact:login:wrapper:
       cmds: |
           before_checksum = checksum(.codeartifact.env)
           task codeartifact:login
           after_checksum = checksum(.codeartifact.env)
           if after_checksum != before_checksum:
               task bootstrap
