How to write secured env variables into file inside docker image in pipelines?

ronpeled

I'm trying to build a pipeline to deploy our serverless architecture. Ideally I can right into a local .env file including all several secured environment variables. I'm assuming the entire docker image is flushed after the pipeline is done deploying so this is really not a security concern. 

However, when I try to write into the file, all env vars write ok except the secured ones. Any idea how to make this work? 

 

script:

# setup local .env file
- touch .env
- echo "DEV_DB_DATABASE=$DEV_DB_DATABASE" >> .env
- echo "DEV_DB_USERNAME=$DEV_DB_USERNAME" >> .env
- echo "DEV_DB_PASSWORD=$DEV_DB_PASSWORD" >> .env
- echo "DEV_DB_HOST=$DEV_DB_HOST" >> .env
- echo "DB_LOGGING=true" >> .env
- echo "SLS_DEBUG=*" >> .env

 

Where ```$DEV_DB_PASSWORD``` is a secured variable. 

 

Thank you!

Oh Yes. No errors. What actually happens is all the normal environment variables gets written as expected. The secured ones translate into the string itself,

so this line:

DEV_DB_DATABASE=$DEV_DB_DATABASE

will show as the following line:

DEV_DB_DATABASE=<name of the db from the env var>

BUT this line:

DEV_DB_PASSWORD=$DEV_DB_PASSWORD

will result in the following line literally:

DEV_DB_PASSWORD=$DEV_DB_PASSWORD

I'm assuming this is some sort of a security mechanism to not 'log' the secured vars but I wonder if there's a way around it or if I'm just doing something wrong. Ideally we actually write the value of the secured vars into the same file so we can then use it in our deploys.

Thanks!
