Docker compose .env file array variable

Question

Im using docker-compose, and Im using env file with my local variables. I need to pass array variable. I have tried:

TAGS="12345","67890"

or

TAGS=["12345","67890"]

or

TAGS=("12345" "67890")

Im getting always error:

List(WrongType(STRING,Set(LIST, OBJECT),Some(ConfigValueLocation(file:/src/target/scala-2.12/classes/application.conf,86))

Any idea how to achieve this ?

Answer 1

As Confidence mentioned above, write a comma separated string:

TAGS=12345,67890

Then in your application (Python for instance):

os.getenv('TAGS').split(',')
